Custom-Made Tamagotchi-Like Device
Features
Physical
- USB - C rechargeable 500 mAh battery
- 3 Tactile buttons for control
- Buzzer for sound feedback
- 128x64 OLED Screen
Digital
- [WIP] Multiple Pets to obtain
- Take care (or don't) of your pets to see the visuals change
- [WIP] Use items obtained randomly on your pets for effects
Why?
I wanted to create this for a couple of reasons:
- I wanted a more complex project to work on
- Tamagotchis are fun and allow me to practice some pixel art skills too
- And finally, because there was a great guide on the Fallout docs :)
The PCB
The PCB was made in KiCAD due to the extensive tools and ability to import own footprints that might not be on EasyEDA

How to Build
[!NOTE] It is recommended to have prior knowledge in electronics and soldering if you want to create one for yourself!
First download the PCB Gerber file from here then send it to your preferred manufacturer! Next buy all of the components from the BOM. For screws and similar items, it is recommended to find the cheapest in your location. Next 3D print the case from here here and ensure the PCB fits once it arrives. Next solder on all of the components and screw the PCB into the case! Finally flash the firmware onto it from here (you might have to build the file on you own computer)
Tada! You now have a PetPad!
(instructions on how to build will improves once I actually physically build one myself :D)

Questions
How big is the Videocraft PetPad PCB?
It measures 50 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Videocraft PetPad use?
13 parts, built around the HS96L03W2C03 and 1207-P6.5MM. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Videocraft PetPad KiCad files?
From the Videocraft10/PetPad repository on GitHub, at the commit this page was made from: the board is KiCad Files/Videocraft PetPad.kicad_pcb and its schematic KiCad Files/OPL_Kicad_Library-master/Grove Vision AI V2 Library/Grove - Vision AI Module V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Videocraft PetPad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
