awesome job with assembling this hackpad! could i ask what happened with the plate? seems like it didn't make the final assembly.

Regardless - enjoy the tickets! Keep building awesome stuff

Soldering, programming & testing

My hackpad kit & PCBs arrived so I got everything ready

I soldered the xiao, switches and OLED onto the PCB (it took quite a while as this was my first time)

I ensured all the connections were soldered properly and programmed the xiao for my keypad

I first made it just type out the number of the key switch that was pressed but later upgraded to my custom binds which include music pause/play, windows lock, task manager, new brower tab and arrow keys.

My 3D printed hackpad case arrived and I put everything together.

I have learnt through making my hackpad: Fusion 360 design for 3d printing, PCB design in KiCad and electronic soldering

Design approved

My design was approved so I have gone through my whole project to ensure everything is accurate and how I want it to be. This included:

  • Measuring & adjusting the 3D model for my case to properly fit my PCB
  • Creating a finalised BOM for my components
  • Double checking my PCB for any errors & running the DRC program on KiCad

Just waiting for the grant to come through so I can order my parts

Thanks, Couldn't find how to reply to your kudos on mine, but I built the desk with my own money, no grant. Am going to see if I can get reimbursed for filament, though.
