Project: Serling is an electronic reproduction of the “Mystic Seer” prop from the Twilight Zone episode “Nick of Time”. In the show, William Shatner’s character becomes obsessed with the seemingly correct predictions of a coin-operated fortune teller machine. The version being built for element14 Presents is a Raspberry Pi-powered device that uses a thermal printer to deliver randomly-selected answers to yes or no questions.

Whether you call them “blinkies”, “throwies”, “sparklers”, or anything else, LED art is an interesting nexus of street art and hacker culture.

Events such as DEFCON even have exhibitions for the most creative blinky designs while maker storefronts sell them in every conceivable shape. In this video, Matt collaborates with his friends at the National Upcycled Computing Collective to build a solar-powered “smart” blinky that not only looks cool at night, but contributes its computing power to a worldwide network that’s looking for disease cures, extraterrestrial intelligence, rogue asteroids, and more!
The Berkley Open Infrastructure for Network Computing (BOINC) allows citizens to donate their spare computing power to help scientific research. In this element14 Presents project inspired by the 2007 Boston Mooninite Panic, we’re going to build a basic electronics hacker project: an LED blinky that not only makes cool designs, but also contributes computing power to BOINC by means of a solar-powered Raspberry Pi!

If you’re going to build a retro gaming device, why not do it with a little style? The TurtlePi starts with a 1989 Konami Teenage Mutant Ninja Turtles LCD handheld with a bad board and replaces the internals using a Raspberry Pi Zero W and Adafruit PiTFT screen to build a TMNT-themed handheld like no other! This video is the grand-prize-winning entry in Element14’s “Hack Like Heck” competition. Special thanks to Element14 and all of my friends, family, and subscribers who supported me in the contest!

TRANSCRIPT:
1
00:00:04,549 –> 00:00:09,590
why don’t we have people send in short
audition videos and put them on the Element
2
00:00:09,590 –> 00:00:14,690
14 community saying hey here’s Who I am
here’s what I do and here’s how I would
3
00:00:14,690 –> 00:00:22,359
approach a raspberry pi affordable okay
and the ten best videos that we oh yeah
4
00:00:22,359 –> 00:00:26,900
what are you doing here we were battling
the shredder and old metal face
5
00:00:26,900 –> 00:00:33,019
destroyed my favorite video game ever I
need your help to fix it well why don’t
6
00:00:33,019 –> 00:00:37,370
you get it Donatello to do it nah he’s
busy working on some project for some
7
00:00:37,370 –> 00:00:42,140
Ben Heck guy whoever that is you think
you can look at it oh yeah this is a
8
00:00:42,140 –> 00:00:51,320
crush a I’ll see what I can do so
apparently Raphael is entrusted me with
9
00:00:51,320 –> 00:00:56,629
this vintage 1989 Teenage Mutant Ninja
Turtles handheld game and well it’s kind
10
00:00:56,629 –> 00:01:01,119
of a one-trick pony though it’s a
rudimentary graphics rudimentary sound
11
00:01:01,119 –> 00:01:08,330
rudimentary gameplay but what if we can
take these design cues and upgrade the
12
00:01:08,330 –> 00:01:14,149
internals we’ll say a Raspberry Pi new
screen etc and we can build something
13
00:01:14,149 –> 00:01:19,939
that celebrates not only a beloved
franchise but retro gaming in general
14
00:01:19,939 –> 00:01:26,299
much the way that the SNES classic or
the NES classic does so here’s my idea
15
00:01:26,299 –> 00:01:37,670
we take said TMNT game which is very
poor part and should be able to fit a
16
00:01:37,670 –> 00:01:47,030
new TFT screen right here we’ll use the
original buttons if I can get some
17
00:01:47,030 –> 00:01:52,939
replacements we use the original buttons
here we use these function buttons we
18
00:01:52,939 –> 00:01:59,659
put a power switch here for the on/off
button and then we’ll just use some tax
19
00:01:59,659 –> 00:02:05,060
switches up underneath we’ll build a new
control set so the screen and a
20
00:02:05,060 –> 00:02:11,840
Raspberry Pi should just fit right here
may have to take much of this out just
21
00:02:11,840 –> 00:02:17,600
to fit everything in but we should be
able to have plenty of room here since
22
00:02:17,600 –> 00:02:21,439
we’re not
gonna use double A’s I should be able to
23
00:02:21,439 –> 00:02:28,280
get a lipo big lipo battery stick it
right in here and use this room for some
24
00:02:28,280 –> 00:02:37,579
extra eternals so this looks like it’s a
very viable project so let me order some
25
00:02:37,579 –> 00:02:43,340
parts and we will start fitting
everything together and see where it
26
00:02:43,340 –> 00:02:52,280
goes so I think my biggest concern here
is the way that the pie and the screen
27
00:02:52,280 –> 00:02:59,150
are gonna fit together inside the case
now of course it looks like they’re
28
00:02:59,150 –> 00:03:03,290
gonna fit so it should be okay but we’ll
know for certain once we get rid of all
29
00:03:03,290 –> 00:03:07,069
this extra plastic here so I’m gonna
mark off all these areas that we’re
30
00:03:07,069 –> 00:03:14,870
gonna cut and then once I have all that
now it’s time to dremel yes I actually I
31
00:03:14,870 –> 00:03:20,209
was afraid of this so the buttons don’t
fit right the screen and they don’t even
32
00:03:20,209 –> 00:03:24,370
line up right so we’re gonna have to
take those
33
00:03:36,780 –> 00:03:44,350
so here are the buttons that we removed
and of course you got a uh can actually
34
00:03:44,350 –> 00:03:47,320
see in here that they just they just
don’t line up right so we’re gonna
35
00:03:47,320 –> 00:03:56,140
actually create a new pad a new
controller to go in here now before we
36
00:03:56,140 –> 00:03:59,020
get building this thing we should
probably at least set up the operating
37
00:03:59,020 –> 00:04:02,830
system on the Raspberry Pi and since
this is a PI based gaming system we’re
38
00:04:02,830 –> 00:04:07,360
gonna use the tried-and-true retro PI so
we’re just gonna jump over to the retro
39
00:04:07,360 –> 00:04:11,620
pie website and grab the image once
that’s finished downloading use an app
40
00:04:11,620 –> 00:04:16,810
like etcher to flash it onto a bootable
SD drive disco now I’ve got to
41
00:04:16,810 –> 00:04:21,520
reconfigure this workstation with the
HDMI monitor the OTG cable and the power
42
00:04:21,520 –> 00:04:27,700
supply in order to set up the Raspberry
Pi for the first boot okay we’ve got a
43
00:04:27,700 –> 00:04:31,780
splash screen this is a good sign so
from here let’s go into the
44
00:04:31,780 –> 00:04:36,330
configuration menu and set up the Wi-Fi
45
00:04:36,630 –> 00:04:42,730
now we need to enable SSH so we’re gonna
go into raspy config then to interface
46
00:04:42,730 –> 00:04:49,150
options SSH and 1/8 now back in the main
retro PI interface I’ll go ahead and
47
00:04:49,150 –> 00:04:53,560
shut down the pi so that I can clear all
the stuff off my workstation now back on
48
00:04:53,560 –> 00:04:58,120
the Mac I’ll just fire around terminal
and ssh into hi now I haven’t changed
49
00:04:58,120 –> 00:05:01,450
the knee of the credentials yet but you
absolutely should do that as soon as
50
00:05:01,450 –> 00:05:08,320
possible now I’m gonna be using a two
fruits 2.2 inch pie TFT hat as the
51
00:05:08,320 –> 00:05:12,730
primary display so I need to enable
support using the script that they were
52
00:05:12,730 –> 00:05:20,320
so good to provide I’ll use option 6 for
the manual configuration and give it a
53
00:05:20,320 –> 00:05:25,990
few minutes for everything to install I
also need to set up a two fruits from
54
00:05:25,990 –> 00:05:29,890
retro game scripts so I can quickly
assign the GPIO breakout pins from the
55
00:05:29,890 –> 00:05:35,330
screen module
we’ll use the hi girls zero settings for
56
00:05:35,330 –> 00:05:42,910
simplicity okay the initial setup is
complete and it’s time to do
57
00:05:44,620 –> 00:05:49,520
okay so I’ve picked up some bakelite
perfboard so I could build a custom
58
00:05:49,520 –> 00:05:54,620
controller without having to roll my own
PCB besides it’s quicker and easier if I
59
00:05:54,620 –> 00:06:00,140
just hand wire everything and I’m gonna
be better able to make adjustments and
60
00:06:00,140 –> 00:06:06,590
changes as necessary if so to start I
just need to lay out my buttons and make
61
00:06:06,590 –> 00:06:10,130
sure I have the correct spacing by using
the front panel of the game then I’ll
62
00:06:10,130 –> 00:06:14,560
press fit my pack switches in the board
and double check the spacing as I go
63
00:06:14,560 –> 00:06:31,600
once everything is lined up right it’s
time to solder
64
00:06:31,600 –> 00:06:35,150
now that all the buttons are soldered
place I’ll go ahead and trim off the
65
00:06:35,150 –> 00:06:39,980
excess bakelite so that the whole board
fits in the case nicely of course this
66
00:06:39,980 –> 00:06:44,090
is why I’m using bakelite instead of
fiberglass because well it’s I can cut
67
00:06:44,090 –> 00:06:47,330
it with scissors I don’t have to get out
the dremel and all the safety equipment
68
00:06:47,330 –> 00:06:51,650
so you know just to make a simple trail
I’m also gonna need to cut out a notch
69
00:06:51,650 –> 00:06:56,690
here to fit this big beefy power button
that I’m gonna install separately now
70
00:06:56,690 –> 00:07:00,490
let’s start working on this screen
assembly
71
00:07:03,590 –> 00:07:09,020
so the PI TFT hat actually comes with a
separate GPIO breakout right here below
72
00:07:09,020 –> 00:07:13,940
the 40 thin connector so that you can
easily attach control wires the cell I’m
73
00:07:13,940 –> 00:07:17,389
going to connect the buttons and I’m
just gonna use a two fruits default
74
00:07:17,389 –> 00:07:25,610
layout for their retro game script to
wire everything for now okay just a
75
00:07:25,610 –> 00:07:29,960
quick orientation check let’s get these
wires soldered to their Horace ponding
76
00:07:29,960 –> 00:07:36,839
buttons
77
00:07:39,690 –> 00:07:47,670
okay now moment of truth it’s time to
solder the pie to the screen module with
78
00:07:47,670 –> 00:07:51,470
all the wires sandwiched in between
79
00:07:57,530 –> 00:08:02,370
now the screen module and the PI are
married I need to ground all these
80
00:08:02,370 –> 00:08:07,560
buttons to a common line so I’ll just
run some ground lines create a couple of
81
00:08:07,560 –> 00:08:13,590
buses and connect all of that to one of
the ground pants on the GPIO now I need
82
00:08:13,590 –> 00:08:18,480
a couple of shoulder buttons and so I’m
going to use these little candy colored
83
00:08:18,480 –> 00:08:24,330
text witches because they’re going to
fit right into the top of these little
84
00:08:24,330 –> 00:08:29,820
shoulders here on the bottom of the case
appropriately enough so I’m going to
85
00:08:29,820 –> 00:08:34,830
need to measure the button cap okay
looks be about 11 millimeters give or
86
00:08:34,830 –> 00:08:45,999
take so now my stepper bit and you get
to chewing through this plastic
87
00:08:56,220 –> 00:09:07,259
looking good so now we need some onboard
audio okay let’s take our USB audio
88
00:09:07,259 –> 00:09:12,120
adapter and and tear off these three and
a half millimeter Jaxx’s we’re not going
89
00:09:12,120 –> 00:09:18,360
to need them instead we’ll just solder
the leads to our speaker directly to the
90
00:09:18,360 –> 00:09:22,920
pads where the headphone jack was it
doesn’t really matter which channel we
91
00:09:22,920 –> 00:09:27,209
use because we’re only going to output
mono sound all these old games did just
92
00:09:27,209 –> 00:09:31,019
fine with mono sound anyway I mean it’s
not like a lot of TVs back in the day
93
00:09:31,019 –> 00:09:36,629
had stereo capabilities anyway
kind of reminds me of the Etta reminds
94
00:09:36,629 –> 00:09:41,730
me of the old game boys you know
dot-matrix with stereo sound but only
95
00:09:41,730 –> 00:09:55,079
one speaker whatever now we should at
least make sure it works now comes the
96
00:09:55,079 –> 00:09:57,660
fun
97
00:09:57,660 –> 00:10:06,810
I need to desolder these wires leading
to the USB plug because well this just
98
00:10:06,810 –> 00:10:11,280
isn’t gonna work
oh yeah and you might want to take note
99
00:10:11,280 –> 00:10:16,590
of where each wire is connected to
logistics anyway with the USB
100
00:10:16,590 –> 00:10:22,530
disconnected I’ll just cut a micro USB
cable that I have lying around and leave
101
00:10:22,530 –> 00:10:28,140
a micro plug and just a few inches worth
of cable strip it down and solder the
102
00:10:28,140 –> 00:10:33,390
individual wires onto the appropriate
pads add a little dab of hot glue to
103
00:10:33,390 –> 00:10:39,840
reinforce the connections and then we’ve
got as a micro USB audio adapter that
104
00:10:39,840 –> 00:10:49,860
should fit just like so now the last
component I have to build before we put
105
00:10:49,860 –> 00:10:53,280
this whole thing together is the power
supply now I’m going to use a two
106
00:10:53,280 –> 00:10:57,810
thousand milliamp power lipo battery to
power the thing with but I’m gonna need
107
00:10:57,810 –> 00:11:02,910
a way to charge it and to distribute
that power so for that I’m gonna use
108
00:11:02,910 –> 00:11:09,720
this a power boost 1000 from Adafruit
it’s actually pretty simple to wire the
109
00:11:09,720 –> 00:11:16,230
battery plugs into this little jack
right here and we just have to run a
110
00:11:16,230 –> 00:11:22,320
couple of wires from these terminals one
goes to a 5 volt pin and the other goes
111
00:11:22,320 –> 00:11:26,490
to the ground pin on the PI I’m also
gonna wire this little clicky button
112
00:11:26,490 –> 00:11:32,820
switch that I have that I’ll use to talk
with power now let’s get these things
113
00:11:32,820 –> 00:11:37,310
soldered up and that’ll be time to put
this bad boy together
114
00:11:39,279 –> 00:11:45,379
so I’ve run into a little bit of a snag
on assembling the speaker that I’m using
115
00:11:45,379 –> 00:11:50,029
is just too big to fit inside the shell
so I’m gonna have to find a smaller
116
00:11:50,029 –> 00:11:55,360
speaker driver to use now fortunately
the fine folks over at Ben Heck show
117
00:11:55,360 –> 00:12:00,500
happened to send me another speaker as
part of the build materials for Ben’s
118
00:12:00,500 –> 00:12:08,149
original bill okay let’s get this bad
boy put together we’re gonna start with
119
00:12:08,149 –> 00:12:14,449
the power boost unit wire that up to the
five volt in and the ground pin on the
120
00:12:14,449 –> 00:12:21,500
Raspberry Pi then we want a route ours
power switch into its appropriate
121
00:12:21,500 –> 00:12:29,209
position all right looking good now we
need to connect the shoulder buttons to
122
00:12:29,209 –> 00:12:34,189
the main controls we’re gonna start by
running ground lines from the ground bus
123
00:12:34,189 –> 00:12:38,029
on the controller out to the shoulder
buttons which I’ve attached to these
124
00:12:38,029 –> 00:12:42,889
small little pieces of perfboard that
I’ve glued into place then we’re going
125
00:12:42,889 –> 00:12:46,689
to connect our signal wires that we
soldered on to the screen module earlier
126
00:12:46,689 –> 00:12:52,100
all right everything’s fitting great now
we just need to add a little hot glue to
127
00:12:52,100 –> 00:12:57,769
hold everything in place and to insulate
our wires okay the last thing we have to
128
00:12:57,769 –> 00:13:02,110
do is Mount our USB audio so we got to
run the cable right around through here
129
00:13:02,110 –> 00:13:07,699
plug it in and cut a little piece of
mounting square we’re gonna tack the
130
00:13:07,699 –> 00:13:15,800
speaker right down on to the battery and
I think we’re actually finished let’s
131
00:13:15,800 –> 00:13:23,430
give it a shot
it works I’ve works it works okay one
132
00:13:23,430 –> 00:13:40,320
more thing I’ve got to do and always got
to sign our work perfect now I just got
133
00:13:40,320 –> 00:13:44,340
to get this back over to Raphael and
we’re good to go okay so the games
134
00:13:44,340 –> 00:13:47,940
intact but I’ve made a few modifications
that I think you’re gonna enjoy let’s
135
00:13:47,940 –> 00:13:57,830
check it out wow this is radical this is
way better than the game I used to play

TRASNCRIPT:
1
00:00:00,030 –> 00:00:04,799
hey folks Atari here I’ve been playing
2
00:00:02,790 –> 00:00:05,580
around with this Robo 3d printer for a
3
00:00:04,799 –> 00:00:07,379
while now
4
00:00:05,580 –> 00:00:10,110
and I think I’ve got the hang of it
5
00:00:07,379 –> 00:00:12,660
finally the thing about 3d printing is
6
00:00:10,110 –> 00:00:14,670
it’s very much a hacker minded hobby
7
00:00:12,660 –> 00:00:17,850
there’s a lot of trial and error
8
00:00:14,670 –> 00:00:20,369
involved in the process and most
9
00:00:17,850 –> 00:00:22,710
consumer grade printers do lack a lot of
10
00:00:20,369 –> 00:00:24,960
the out-of-the-box features got some of
11
00:00:22,710 –> 00:00:27,539
the higher-end printers include which
12
00:00:24,960 –> 00:00:30,300
leads people like me to go ahead and
13
00:00:27,539 –> 00:00:32,750
build their own upgrades what I’ve done
14
00:00:30,300 –> 00:00:36,090
here is I’ve installed a Raspberry Pi
15
00:00:32,750 –> 00:00:39,420
with the octoprint software to make a
16
00:00:36,090 –> 00:00:42,719
self-contained Wi-Fi printer and then I
17
00:00:39,420 –> 00:00:45,809
installed a webcam to capture time-lapse
18
00:00:42,719 –> 00:00:48,510
videos of the print process as well as
19
00:00:45,809 –> 00:00:51,449
some LED lighting for better video
20
00:00:48,510 –> 00:00:53,390
capturing and then I’ve you know kind of
21
00:00:51,449 –> 00:00:57,390
rejiggered the cabling and the filament
22
00:00:53,390 –> 00:00:58,559
feeds so that they’re going to move a
23
00:00:57,390 –> 00:01:01,949
little bit better and they don’t be
24
00:00:58,559 –> 00:01:03,629
caught up in may in the works inside it
25
00:01:01,949 –> 00:01:08,280
just makes for a whole lot better
26
00:01:03,629 –> 00:01:11,310
experience so this video is going to
27
00:01:08,280 –> 00:01:16,350
walk you through the process that I use
28
00:01:11,310 –> 00:01:19,320
to install these physical upgrades but I
29
00:01:16,350 –> 00:01:21,659
will have a link in the doobly-doo and
30
00:01:19,320 –> 00:01:26,150
probably up here in the corner a link to
31
00:01:21,659 –> 00:01:30,600
a full how-to article about about
32
00:01:26,150 –> 00:01:33,479
installing and setting up octoprint on
33
00:01:30,600 –> 00:01:35,100
the Raspberry Pi or octopi as its called
34
00:01:33,479 –> 00:01:38,220
I will put a link to that I’ll have a
35
00:01:35,100 –> 00:01:40,680
full write-up on airborne surfer comm so
36
00:01:38,220 –> 00:01:42,720
you can follow that guide there but
37
00:01:40,680 –> 00:01:46,380
again this is going to walk through the
38
00:01:42,720 –> 00:01:48,509
physical installation and with that with
39
00:01:46,380 –> 00:01:50,579
the write-up on the software that should
40
00:01:48,509 –> 00:01:52,680
get you through a pretty much down the
41
00:01:50,579 –> 00:01:54,840
gist of it the first thing I’m going to
42
00:01:52,680 –> 00:01:56,939
fix is the zip tie loop for the cable
43
00:01:54,840 –> 00:01:58,770
loom having a zip tie here has been
44
00:01:56,939 –> 00:02:01,950
holding the Loom a little too rigidly
45
00:01:58,770 –> 00:02:03,930
and has led to a few failed prints I’ve
46
00:02:01,950 –> 00:02:06,210
already cut the zip ties since removing
47
00:02:03,930 –> 00:02:08,640
the hood and now I need to replace the
48
00:02:06,210 –> 00:02:10,500
mounting point for the zip tire I found
49
00:02:08,640 –> 00:02:13,140
a suitable two piece cable loop on
50
00:02:10,500 –> 00:02:15,480
Thingiverse that holds the Loom in
51
00:02:13,140 –> 00:02:18,240
face while being loose enough to allow
52
00:02:15,480 –> 00:02:20,000
some play in the tension remove the two
53
00:02:18,240 –> 00:02:23,459
screws holding the loop mount in place
54
00:02:20,000 –> 00:02:25,740
then replace it with the base of the
55
00:02:23,459 –> 00:02:29,580
two-piece print hang on to the second
56
00:02:25,740 –> 00:02:31,709
piece for later next thing to do is
57
00:02:29,580 –> 00:02:34,500
install some lighting I picked up the
58
00:02:31,709 –> 00:02:37,680
self-adhesive USB powered LED strip from
59
00:02:34,500 –> 00:02:40,530
Amazon and ran it along the interior of
60
00:02:37,680 –> 00:02:42,630
the hood be sure to start with the USB
61
00:02:40,530 –> 00:02:44,790
plug on the slide with the cable well
62
00:02:42,630 –> 00:02:48,239
this is the same side that the loop
63
00:02:44,790 –> 00:02:51,120
mount is installed now before we put the
64
00:02:48,239 –> 00:02:53,459
hood back on go ahead and unplug the USB
65
00:02:51,120 –> 00:02:56,820
cable and the power cable from the
66
00:02:53,459 –> 00:02:59,130
printer place the hood back onto the
67
00:02:56,820 –> 00:03:02,130
base of the printer with the cable loop
68
00:02:59,130 –> 00:03:04,350
on the same side as the well make sure
69
00:03:02,130 –> 00:03:07,170
all the wiring is tucked inside the hood
70
00:03:04,350 –> 00:03:10,170
before pressing down to properly align
71
00:03:07,170 –> 00:03:14,550
the screw holes then screw the hood
72
00:03:10,170 –> 00:03:17,489
securely in place now gently lift the
73
00:03:14,550 –> 00:03:19,440
printer and set it on its side make sure
74
00:03:17,489 –> 00:03:21,810
to hold on to the print cartridge and
75
00:03:19,440 –> 00:03:24,870
abed as they’re likely to slide around
76
00:03:21,810 –> 00:03:26,790
to install the Raspberry Pi we’re going
77
00:03:24,870 –> 00:03:29,190
to need to siphon some electricity from
78
00:03:26,790 –> 00:03:32,340
the printers power supply specifically
79
00:03:29,190 –> 00:03:40,590
from the AC input coming from the switch
80
00:03:32,340 –> 00:03:43,590
on the back of the unit the power supply
81
00:03:40,590 –> 00:03:44,610
on a robo 3d printer is a tough zombie
82
00:03:43,590 –> 00:03:46,769
to remove
83
00:03:44,610 –> 00:03:50,040
there aren’t any screws or anything it’s
84
00:03:46,769 –> 00:03:53,430
just held in the friction very tightly
85
00:03:50,040 –> 00:03:56,190
as you can see taking quite a bit of
86
00:03:53,430 –> 00:03:58,950
effort to remove I found that shifting
87
00:03:56,190 –> 00:04:01,380
it down at an angle back and forth will
88
00:03:58,950 –> 00:04:04,290
garner the quickest results but your
89
00:04:01,380 –> 00:04:06,810
mileage may vary so here are the
90
00:04:04,290 –> 00:04:09,049
terminals these four go into the Arduino
91
00:04:06,810 –> 00:04:13,790
board that controls the printer and
92
00:04:09,049 –> 00:04:19,289
these three are for the AC what dish
93
00:04:13,790 –> 00:04:20,489
blue brown green and yellow OnLive just
94
00:04:19,289 –> 00:04:24,639
get get somebody killed
95
00:04:20,489 –> 00:04:27,039
you see standards exist for a reason
96
00:04:24,639 –> 00:04:29,889
well they exist for many reasons but one
97
00:04:27,039 –> 00:04:33,099
of them is safety international standard
98
00:04:29,889 –> 00:04:35,289
wiring colors are such so that one does
99
00:04:33,099 –> 00:04:37,710
not accidentally connect the wrong
100
00:04:35,289 –> 00:04:41,439
conduct to do the wrong terminal or
101
00:04:37,710 –> 00:04:47,740
worse touch the wrong live conductor
102
00:04:41,439 –> 00:04:50,199
this is wrong this is it’s good right
103
00:04:47,740 –> 00:04:57,370
I mean bed at least the goddamn
104
00:04:50,199 –> 00:04:59,770
terminals are clearly marked anyway
105
00:04:57,370 –> 00:05:02,919
we’re going to need to tap into these
106
00:04:59,770 –> 00:05:05,139
leads to direct power to a standard 110
107
00:05:02,919 –> 00:05:07,180
volt outlet so that we can use an
108
00:05:05,139 –> 00:05:08,379
off-the-shelf power converter to power
109
00:05:07,180 –> 00:05:10,870
the Raspberry Pi
110
00:05:08,379 –> 00:05:14,169
we’ll start by loosening the terminal
111
00:05:10,870 –> 00:05:16,629
screws and removing the leads I picked
112
00:05:14,169 –> 00:05:19,210
up this outlet saver at micro Center for
113
00:05:16,629 –> 00:05:21,310
a couple of dollars essentially it’s a
114
00:05:19,210 –> 00:05:23,919
10 inch long grounded extension cord
115
00:05:21,310 –> 00:05:26,770
take a pair of scissors and cut off the
116
00:05:23,919 –> 00:05:29,589
plug-in then strip away the outer casing
117
00:05:26,770 –> 00:05:32,740
leaving just the outlet end and the
118
00:05:29,589 –> 00:05:35,949
exposed inner wiring at least these
119
00:05:32,740 –> 00:05:37,779
wires are the proper colors so now we
120
00:05:35,949 –> 00:05:40,569
just need to strip the end of the
121
00:05:37,779 –> 00:05:43,330
insulation off of each of the wires so
122
00:05:40,569 –> 00:05:45,940
we can hook them up to the terminal now
123
00:05:43,330 –> 00:05:48,969
remember kids ground is green like grass
124
00:05:45,940 –> 00:05:51,960
on the ground white is neutral because
125
00:05:48,969 –> 00:05:55,719
it’s the neutral color and black is live
126
00:05:51,960 –> 00:05:58,060
because black lives matter anyway
127
00:05:55,719 –> 00:06:01,270
so we reinsert the leads from the switch
128
00:05:58,060 –> 00:06:04,240
into the proper terminal then insert the
129
00:06:01,270 –> 00:06:06,810
new leads from the extension cord into
130
00:06:04,240 –> 00:06:10,599
the appropriate terminals as well and
131
00:06:06,810 –> 00:06:13,270
tighten the retaining screw then simply
132
00:06:10,599 –> 00:06:19,629
reposition the power supply back inside
133
00:06:13,270 –> 00:06:21,789
its retainer with a good shove now we’re
134
00:06:19,629 –> 00:06:23,770
going to need to run a USB cable to
135
00:06:21,789 –> 00:06:26,259
connect the Arduino to the Raspberry Pi
136
00:06:23,770 –> 00:06:28,900
and because the Arduino is mounted so
137
00:06:26,259 –> 00:06:31,330
close to the edge of the base we’re
138
00:06:28,900 –> 00:06:33,789
going to use this right angle USB cable
139
00:06:31,330 –> 00:06:36,279
to make the connection now even with the
140
00:06:33,789 –> 00:06:38,409
low profile of the right angle cable
141
00:06:36,279 –> 00:06:41,469
though we’re going to need to
142
00:06:38,409 –> 00:06:43,569
move the Arduino to plug in the cable so
143
00:06:41,469 –> 00:06:46,179
just remove these three mounting screws
144
00:06:43,569 –> 00:06:48,669
from the Arduino and carefully plug in
145
00:06:46,179 –> 00:06:51,309
the USB cable you can use the existing
146
00:06:48,669 –> 00:06:54,219
wires to hold the new USB cable in place
147
00:06:51,309 –> 00:06:57,009
just be careful not to pull any of the
148
00:06:54,219 –> 00:06:58,959
wires from the Arduino screw the Arduino
149
00:06:57,009 –> 00:06:59,619
back into place and you’re done with
150
00:06:58,959 –> 00:07:03,279
step 2
151
00:06:59,619 –> 00:07:05,769
I found the simple mouth for a Raspberry
152
00:07:03,279 –> 00:07:08,379
Pi on Thingiverse but I also printed if
153
00:07:05,769 –> 00:07:10,959
you get the hole size right you can use
154
00:07:08,379 –> 00:07:12,610
screws to mount the pie in place but I’m
155
00:07:10,959 –> 00:07:15,339
just going to use glue as it’s a little
156
00:07:12,610 –> 00:07:17,439
easier than drilling out the hole apply
157
00:07:15,339 –> 00:07:20,349
the glue to the mount and press the
158
00:07:17,439 –> 00:07:22,419
Raspberry Pi board into place some glue
159
00:07:20,349 –> 00:07:24,279
should come through the holes in the pie
160
00:07:22,419 –> 00:07:26,409
and mushroom over to provide a pretty
161
00:07:24,279 –> 00:07:29,919
good hole clamp some parts together
162
00:07:26,409 –> 00:07:32,110
until the glue sets apply glue along the
163
00:07:29,919 –> 00:07:35,050
perimeter of the mouth and press it into
164
00:07:32,110 –> 00:07:36,669
place on the bottom of the printer make
165
00:07:35,050 –> 00:07:39,779
sure to hold it tightly against the base
166
00:07:36,669 –> 00:07:42,579
of the printer until they do the sex
167
00:07:39,779 –> 00:07:45,789
finally plug the printer into one of the
168
00:07:42,579 –> 00:07:48,279
USB ports on the pie plug one end of a
169
00:07:45,789 –> 00:07:50,529
USB to micro USB cable into the power
170
00:07:48,279 –> 00:07:52,659
port on the Raspberry Pi and the other
171
00:07:50,529 –> 00:07:54,999
end into a wall wart power converter I
172
00:07:52,659 –> 00:07:57,669
think this one up at Tashi station for
173
00:07:54,999 –> 00:07:59,860
about 5 imperial credits just make sure
174
00:07:57,669 –> 00:08:02,709
it’s rated for at least 5 volts and 1
175
00:07:59,860 –> 00:08:04,689
ampere plug your power converter into
176
00:08:02,709 –> 00:08:07,239
your hacked up power outlet from earlier
177
00:08:04,689 –> 00:08:10,839
and now your pie is powered on by the
178
00:08:07,239 –> 00:08:12,759
main switch on the printer again you can
179
00:08:10,839 –> 00:08:16,719
use the existing wiring to hold your new
180
00:08:12,759 –> 00:08:18,579
wiring in place I picked up a short USB
181
00:08:16,719 –> 00:08:20,259
extension cable to connect the lighting
182
00:08:18,579 –> 00:08:24,369
to the PI as well so I just need to
183
00:08:20,259 –> 00:08:26,259
connect that the last USB connection is
184
00:08:24,369 –> 00:08:28,479
made for the webcam which will record
185
00:08:26,259 –> 00:08:30,699
our time-lapse videos for this i’ll
186
00:08:28,479 –> 00:08:32,589
thread the USB cable from the front of
187
00:08:30,699 –> 00:08:34,659
the printer through the cable well to
188
00:08:32,589 –> 00:08:37,350
the underside of the printer and connect
189
00:08:34,659 –> 00:08:40,120
it to the Raspberry Pi
190
00:08:37,350 –> 00:08:41,950
before setting the printer up light go
191
00:08:40,120 –> 00:08:44,500
ahead and insert the cable loom in place
192
00:08:41,950 –> 00:08:46,690
inside the loop installed earlier and
193
00:08:44,500 –> 00:08:51,220
enclose it with the locking piece then
194
00:08:46,690 –> 00:08:52,900
carefully write the printer this is a
195
00:08:51,220 –> 00:08:54,670
widget that I designed myself and
196
00:08:52,900 –> 00:08:56,980
Tinkercad and I’ll put a link to it in
197
00:08:54,670 –> 00:08:58,900
the doobly-do what it does is it clamps
198
00:08:56,980 –> 00:09:01,270
onto the edge of the print bed and
199
00:08:58,900 –> 00:09:03,970
allows you to mount a clamp style webcam
200
00:09:01,270 –> 00:09:06,130
level with the print bed so you can
201
00:09:03,970 –> 00:09:09,490
capture time-lapse video that stabilize
202
00:09:06,130 –> 00:09:11,860
to the y-axis stabilizing one axis is
203
00:09:09,490 –> 00:09:13,480
nice because otherwise motion gets
204
00:09:11,860 –> 00:09:17,410
really messy and you can’t really see
205
00:09:13,480 –> 00:09:19,180
much detail in your printing lastly
206
00:09:17,410 –> 00:09:20,800
we’re going to turn the printer around
207
00:09:19,180 –> 00:09:23,410
to the back so I can install the new
208
00:09:20,800 –> 00:09:25,180
spool holder that I printed this is a
209
00:09:23,410 –> 00:09:27,940
replacement for the stock holder that
210
00:09:25,180 –> 00:09:29,590
hangs off the side of the hood this one
211
00:09:27,940 –> 00:09:31,720
keeps the footprint of the printer a
212
00:09:29,590 –> 00:09:33,700
little smaller and keeps the filament
213
00:09:31,720 –> 00:09:35,620
closer to the center axis of the printer
214
00:09:33,700 –> 00:09:38,470
which helps keep the feed steady
215
00:09:35,620 –> 00:09:40,060
preventing jams and tangles and it just
216
00:09:38,470 –> 00:09:43,290
grips onto the side of the hood and
217
00:09:40,060 –> 00:09:43,290
slides down to lock in place
218
00:09:43,950 –> 00:09:48,580
now if you’ll install these upgrades as
219
00:09:46,690 –> 00:09:50,530
soon as possible after setting up your
220
00:09:48,580 –> 00:09:51,730
logo through the printer you’ll find
221
00:09:50,530 –> 00:09:55,030
that you’re going to get a much better
222
00:09:51,730 –> 00:09:57,370
and much more consistent quality in your
223
00:09:55,030 –> 00:10:01,540
prints and you’ll have a lot fewer
224
00:09:57,370 –> 00:10:03,250
headaches along the way so anyway thanks
225
00:10:01,540 –> 00:10:05,320

Having a 3D printer at your disposal is pretty amazing, but it can be a pain when you have to keep the printer tethered to your working computer for hours (or even days) while it runs! I was looking for a simple solution to drive my printer while I used my laptop for other purposes (like going to work during the week) when I came across OctoPrint, an open-source 3D printer web interface for controlling and monitoring the printer from a remote computer. The software essentially creates a running web server for the printer and takes the place of printing suites like MatterControl or Repetier, so it does require running on a machine connected to the printer via USB. If you have an old PC gathering dust, you can easily set it up and have a permanent print station. I, however, don’t have the luxury of a lot of space, so I wanted a more portable option that I could pull out when I needed to use it and easily put away. For this, I chose the Raspberry Pi as it is small enough to easily fit into the printer’s form factor, doesn’t require much electricity to run, and has built-in WiFi compatibility. The OctoPrint software even comes as a complete Linux distro optimized for Raspberry Pi called OctoPi.
Out of the box, OctoPi incorporates the LAMP stack for web hosting, a complete OctoPrint installation (including dependencies) for controlling the 3D printer, the mjpg-streamer package for streaming timelapse videos of the print process, and CuraEngine for slicing. This last item, however, is really moot because of the anemic computing power of the Raspberry Pi. I prefer to slice models on my working computer then transfer over the network to OctoPi for printing.
OctoPi is a pretty simple setup with a lot of really good documentation both at the OctoPrint.org site and their GitHub page. To start, make sure you have Etcher installed and simply download the latest stable version from http://octopi.octoprint.org/download (Be sure to grab the md5 file to verify the download as well!). Unzip the downloaded image and burn it to your SD card using Etcher like you would any other RPi image.
Open the newly burnt SD card as a removable drive in your computer’s file explorer. In the root folder of the SD card, use a text editor to open octopi-network.txt and edit the file as necessary to match your network configuration. Don’t forget to delete the # at the beginning of the appropriate lines or OctoPi will not connect to the network!
Eject the SD card from your computer, pop it into the Raspberry Pi, run a USB cable from the Pi to the printer, and turn on the Pi by plugging it into a power supply. Give the Pi a minute to boot up, and SSH into it from your main computer. The Pi will be located on the network as octopi.local (or an IP address assigned by the router). As usual, the default username is pi and the default password is raspberry.
Change the password using the passwd command, then close your SSH session.
Open a browser on your main computer and point it to octopi.local (or the assigned IP address). The OctoPrint interface will open with the “First-Run Wizard” and prompt you to set up access controls such as username and password. This is specific to OctoPrint and independent of the username and password used to access the Pi via SSH. If you don’t plan on having your printer exposed to the Internet or having anyone else connecting to your network, you may disable access control. I keep it active just in case, so disable at your own risk!
Reboot OctoPi through the menu at the top right of the screen, and you will be all set to print! If you need more help, check out the README section of the GitHub page or drop a comment below!
