Here’s an update to Chris Fenton’s FIBIAC FIBIAC – Punchcard Computing 3D Printed Electromechanical Computer:
A long time ago (after I built my FIBIAC), my friends at Makerbot used their botfarm to make a boatload of 3-digit counters for me. I hadn’t really decided what to do with them at the time, but I thought it would be fun to see how far I could push the delightfully-inefficient instruction-set architecture I had come up with. After languishing for 2 years or so, I finally decided to do something with them. The punch-card chain of the FIBIAC has been replaced by a somewhat more robust stepper-driven instruction drum, and there are now 8 (!) 3-digit counters. Here is a short test video of it running a 4-instruction ‘Difference Engine Emulator’, and computing a table of x^2 (1, 4, 9, 16, 25 …). The final result shows up on the 4th counter from the left (the white one) after every iteration. Enjoy =)
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here
