Stepper Driver Module with Swappable Heatsinks

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…

Hackaday: A Fidget Spinner We Can Love

 

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…

Prototyping, Making A Board For, And Coding An ARM Neural Net Robot

[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…

An Interview with Alex Williams, Grand Prize Winner

 

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…

Interface the Raspberry Pi Zero W to Commodore 64

Leif Bloomquist has designed a board to interface the Raspberry Pi Zero W to the Commodore 64 through the User Port.

Raspberry Pi Zero W / Commodore 64 Interface Board

Project goals:

1. Get a Linux shell prompt on your C64 through the Pi Zero’s Console Pins.

2. Use the Pi Zero as a virtual Floppy Disk Drive through raspbiec (https://github.com/Flogistoni/raspbiec) (another option is ninepin, https://github.com/FozzTexx/ninepin)

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)

 

  • 1 × Commodore 64
  • 1 × Raspberry Pi Zero W
  • 1 × 75HC245 For 5V / 3.3V translation
  • 1 × Custom board To be designed.

Hackaday: What Actually Happens At A Hardware Hacking Con

 

The Hackaday Superconference was last weekend, and it was the greatest hardware con on the planet. What can you build out of a conference badge? If you answered “a resin-based 3D printer” you would have won a prize. If you decided to put your badge in a conference water bottle and make a stun gun…

Vectrex cartridge

This is my first version of a PCB for building a Vectrex cartridge. I used this for my Kickstarter project for the Bloxorz game. The PCB was manufactured by @oshpark , you can order your board here.

1073231511269047209

It fits in this 3D printed case from Thingiverse (you can order it here in my Shapeways shop), or in one of the nice new injection molded cartridge shells from Sean Kelly

Frank has launched a Kickstarter campaign:

FrankBuss has shared the board on OSH Park:
