GalaxyMouse V1

Materials used:

• A lot of 0.5mm diameter copper wires
• 5mm copper adhesive
• Solder wire
• 6x M3 by 8 bolts
• 4x M3 nuts
• 90x brass spacers
• 90x M3 by 8 headless screws
• PLA
• The keycaps were 3D printer in resin
• Arduino pro micro
• PS2 joycon
• 2x springs for knob
• Bearing ball 22x8x6.5
• 6x M1 x10 bolts
• 4x M3 by 3 bolts
• 30x mechanical keyswitches
• Braded cable wire

3D printing

You need a really calibrated first layer to be able to print the array of cables without any lift in the print

Make sure you got dialed in the dimensional accuracy aswell

Now the supports, for the wrist holder you need a really good calibrated supports, because it’s going to be a pain in the ass to remove them

Assembly

Use the youtube video I posted for additional help with assembly: 

First start with routing the wires from both the main body and the numpad, don’t connect them yet.

Solder the Arduino and joycon pins.

Then install the keyswitches and check if the 5 main buttons are connected and work properly, if they don’t

Check if they are connecting with the copper wires

Now assemble the knob, the piece that installs over the joycon, you can regulate the travel it takes for the limit switches to click, remember to solder properly the limit switches, to need to stay normally open, and close when they click

After that look on the 3D model to see what cable from the main body connects to the numpad, and you are done!

Firmware

https://github.com/Razberry97/Firmware-GalaxyMouseV1

this is the github repository, inside you will find a requirements.txt that explains what you need

one thing I forgot to mention, you need to install keypad.h for Arduino ide
