Before “soccer mom” was a pejorative, there were the detergent commercials.
As a child of the 1980s, I’ve been fascinated by the apparent complexity of Rubik’s Cube–the world-famous puzzle toy designed by Hungarian architect Emö Rubik–but I could never solve one past peeling the stickers and placing them in the correct position (a trick my uncle taught me that could be used to “mess with the Cube nerds”). I’ve had a newer model sitting around for a few years, and as one of my “COVID Side Projects”, I finally learned the proper way to solve the Cube.
Building the yellow cross:
If you have no yellow edge pieces on the top face, then F U R U’ R’ F’
If you have a line of yellow pieces through the center, then reorient the entire cube so that the line is vertical to your perspective and F U R U’ R’ F’
If you have two yellow edge pieces making an “L” shape, then turn the top layer until the edge pieces are in the 12:00 and 9:00 positions and F U R U’ R’ F’
Solving the yellow face:
If there are 0 or 2 yellow corners showing, then R U R’ U R U2 R’
If there is 1 yellow corner showing (“the goldfish”), then turn the top layer until the yellow corner piece is in the lower left of the face (the “goldfish” will be diving to the left) and R U R’ U R U2 R’
Set up the top layer:
If there are no matching corner pieces on any faces of the top layer, then L’ U R U’ L U R’ R U R’ U R U2 R’
If there is a set of matching corner pieces on a face, then reorient the cube so that face is on the left and L’ U R U’ L U R’ R U R’ U R U2 R’
Continue until there are matching corner pieces on all 4 faces
Solve the top layer:
F2 U’ R’ L F2 L’ R U’ F2
Continue until the top layer is solved, then rotate the top layer to solve faces as necessary.
For Project Rankin to come alive, I needed it to have some level of audio, but I didn’t want to plug some USB solution in or even use the on-board mini jack if I could help it, so I figured out a quick hack to get sound from the Raspberry Pi A+ out to a simple speaker.
That jingle, though!
Could you get any less subtle with a compilation of love songs called “Tonight’s The Night”?
After the 1991 “Cinderella Season” for the Atlanta Braves, every local business suddenly caught Braves Baseball Fever and tried to tie them in to promotions in every conceivable way.
Does anyone remember this show? Seems like it was a follow-up to the wildly popular “Rescue 911” and CBS’s answer to Fox’s “COPS”
As part of Project Rankin, I need to be able to convert 120VAC to a more usable 5VDC, so I’ll be using a ubiquitous wall wart. However, I want to keep it as clean and tidy as possible, so I need to wire the adapter directly into the project itself. While I’ve got the case off, I’ll walk through the basic components and how an AC adapter works.
Millions of teeth can’t be wrong?
