At first glance, [Dean Gouramanis]’s stepper driver module for 3D printers looks like just another RAMPS-compatible stepper board. Except, what could that gold-plated copper peg sticking out of the PCB possibly be? That would be [Dean]’s PowerPeg Thermal Management System that he built and entered in the Hackaday Prize competition for 2015, where it rocked…
We’ve been frankly mystified at the popularity of fidget spinners. After all, we can flip an ink pen around just fine. However, [MakersBox] just sold us on what he calls the geek spinner. The fact that the spinner is actually a PCB and has parts on it, would probably have been cool enough. However, the…
[barbouri] found a few old (vintage?) parts from the early ’80’s while rummaging through his parts bin, and quickly spun out a small PCB to build a 10.000 V reference using these old ICs. Throwing together a small number of parts, he was able to build a source which might be good enough to use…
[Sean Hodgins]’s calls his three-part video series an Arduino Neural Network Robot but we’d rather call it an enjoyable series on prototyping, designing a board with surface mount parts, assembling it, and oh yeah, putting a neural network on it, all the while offering plenty of useful tips. In part one, prototype and design, he starts…
Alex Williams pulled off an incredible engineering project. He developed an Autonomous Underwater Vehicle (AUV) which uses a buoyancy engine rather than propellers as its propulsion mechanism and made the entire project Open Source and Open Hardware. The design aims to make extended duration missions a possibility by using very little power to move the…
The next Hardware Happy Hour (3H) Chicago will be this Tuesday, November 28th:
Hope to see you there!
1. Get a Linux shell prompt on your C64 through the Pi Zero’s Console Pins.
3. Allow your C64 to access the Internet, USB, etc. through the Pi Zero. ssh!
4. Provide Composite Video out from the Pi Zero that is usable directly on a Commodore monitor.
5. (Stretch Goal #1) If possible – use your C64’s keyboard as the keyboard on the Pi Zero (through the serial port). Maybe through softwedge? (https://github.com/theatrus/softwedge)
6. (Stretch Goal #2) Add PWM audio output (along the lines of https://learn.adafruit.com/introducing-the-raspberry-pi-zero/audio-outputs)
