Hand tools and fabrication machines
This is a demo board to showcase the HCC Module, but its cool enough to be its own tutorial. I've done a macro board in the past, but I really wanted to do one with Cherry MX Mechanical switches. So here it is! The Modzilla.Step 1: Watch the Video!Step 2: Get the Parts!
There aren't that many for this build. Should be pretty easy!
- Modzilla PCB from PCBWay - PCBWAY PCB
- HCC Module - Currently Kickstarter (Or make your own!)
- 8 x Cherry MX Switches - Digikey
- 2 x 1uF Capacitor - Digikey
- 1 x USB Connector - Digikey
- 5 x M1.91 Plastic Threading Screws
- Soldering Iron
- Reflow oven
- Solder Paste
- 3D Printer(If printing the Frame)
- Screwdriver with appropriate head
The frame is very simple, quick print. You could use spacers and screws if you want instead if you don't have a printer.
If you do, download the frame on Thingiverse here.Step 4: Add Solder Paste for Surface Mount Components
I did this manually. Can be a bit tricky with the APA102 LEDs! One trick is to use a toothpick or small piece of wire to transfer the solder paste to small components.Step 5: Add Components
Place the components one by one.Step 6: Bake in the Oven
The HCC Module solders really easily!Step 7: Test the Board!
Here is a demo program that works with the HCC Module to test the LEDs.
Find the "LED Test" code below.Step 8: Add the Key Switches and Solder!
These only have two pins, and rely on the solder to hold them on. Again, its a simple design, but it works for this!Step 9: Program Again!
I've attached the Arduino code, and in the video I explain what each part does, so you can setup your own Macros! Find the code "Macro Keypad Firmware" Below.Step 10: Assemble!
I used plastic threading screws to mount the board to the 3D print.Step 11: Done!
It works!Step 12: Support These Projects!
This project uses the HCC Module, which is a project that I am currently Kickstarting! If you would like to support me and my projects, the Kickstarter is a great place to do so, and you can make stuff like this Macro Keyboard!
