Cellular Automata Explorer

Posted on by

Well all know cellular automata from Conway’s Game of Life which simulates cellular evolution using rules based on the state of all eight adjacent cells. [Gavin] has been having fun playing with elementary cellular automata in his spare time. Unlike Conway’s Game, elementary automata uses just the left and right neighbors of a cell to determine the next cell ahead in the row. Despite this comparative simplicity, some really complex patterns emerge, including a Turing-complete one.

[Gavin] started off doing the calculations by hand for fun. He made some nice worksheets for this. As we can easily imagine, doing the …read more

E-paper looks awesome, but it’s a pain to work with. You need only look at the homebrew implementations of e-paper drivers and the mess of SMD components for proof of that. [jarek] wanted to play around with e-paper and developed this tiny little driver for a Teensy. It’s a fun toy, and the simplest possible circuit necessary to drive this particular e-paper module.

I am once again asking if anyone knows where to buy this computer case. No, not a complete system – I just want the case, folding keyboard, and monitor integrated into an mATX enclosure.

Back in 1985, …read more

Have a Laser Cutter? He’s a Cool Combination Lock Box You Can Build!

Posted on by

Laser-cut plywood boxes are cool. Don’t believe me? Take a look at the free projects out there for people to get started with when they get a laser cutter – it’s obviously a popular genre of project. Laser cut plywood boxes with combination locks are even cooler, especially when the combination is entered on four separate number selectors, on four sides of the very same box.

That’s exactly what [Sande24] has done, and the final result is mesmerizing. 30-40 parts are cut from plywood with a laser cutter, and assembled to construct the lockbox. The design could easily be reused …read more

Battletech Case Mod Displays Awesome Woodwork, Hides Hacks

Posted on by

[S.PiC] has been working on a computer case styled to look like the Vulture mech from Battletech. We’re not sure if his serious faced cat approves or not, but we do.

The case is made from artfully cut plywood. We kind of hope he keeps the wood aesthetic. However, that would be getting dangerously close to steampunk. So perhaps a matching paint job at the end will do. In some of the videos we can how he’s cleverly incorporated the computer’s components into the design of the case. For example, the black mesh on the front actually hides the computer’s …read more

Fourier Machine Mimics Michelson Original in Plywood

Posted on by

It’s funny how creation and understanding interact. Sometimes the urge to create something comes from a new-found deep understanding of a concept, and sometimes the act of creation leads to that understanding. And sometimes creation and understanding are linked together in such a way as to lead in an entirely new direction, which is the story behind this plywood recreation of the Michelson Fourier analysis machine.

For those not familiar with this piece of computing history, it’s worth watching the videos in our article covering [Bill “The Engineer Guy” Hammack]’s discussion of this amazing early 20th-century analog computer. Those videos …read more
