05/01/26 - Firmware and Pinouts

Researched on the pinout connections between the raspberry pi and both the display and RTC clock, creating a connections diagram.

Created the code for the linux driver to be load the time from the RTC into the raspberry pi on boot!

And other repo changes and fixes! :P

26/12/25 - Best firmware and how flashing works

Due to the Raspberry Pi Zero having less CPU power, using an image of pwnagotchi without AI could end up having better returns instead. Although I'll be testing both haha once I get the RP board :P

This is the repository that contains the optimized Pwnagotchi firmware.

Flashing the firmware looks as easy as plugging in an SD Card and hitting flash on the Raspberry Pi imager!

Also to get accurate results, I noticed that I will need to get an RTC battery for the project! So that every time I plug the Raspberry Pi with external power it will know the time and date, so logs are correctly logged. A DS3231 module is fairly inexpensive, at less than 2 euros, and will normally fit in between the Display and the RP0 board inside the same CAD design I made 5 days ago :p

21/12/25 - CAD case design & more research

So after some extra research I discovered that a multi-color e-paper might not be too good of an idea due to the refresh rate speeds, going from around 3 seconds to 15 or more per frame. This is quite a drawback and made me chose a B&W display instead.

Today I also made the cad design for a case to house the raspberry pi zero and the display inside. It features side holes to access the usb ports, hdmi port and the micro sd card slot. Also I added a lanyard loop slot to the other side of the case!
Regarding the top closing part I feel it's more prudent to wait to order and receive the display first so I can take exact measurements.

17/12/25 - Parts fetching and it can have pokemon!!!

So today I looked more into it, and discovered that apparently I can add custom faces including Pokemon!! There are so many resources for this project over on pwnagotchi.org and a very cool community on Discord and on Reddit!

I found a good E-Paper display on AliExpress and a Raspberry Pi Zero 2W on a local shop near me.

Next up I'll study how the Pwnagotchi Firmware is loaded onto the Raspberry Pi, and will design a custom case to house the whole build.

16/12/25 - Research on Pwnagotchis and how they work

I researched what I need to build this project and it seems pretty straight forward! A Raspberry Pi Zero, around 40 pin headers and an E-Paper display! I could also add a battery but for something that I'm planning to stay on my desk I don't find it a very good investment for 35 bucks. Idk how batteries for raspberry pi are so expensive...

There is this really cool website with instructions and multiple build tutorials: pwnagotchi.org

This uses AI to fetch packets and then learns what methods are best to capture as much packets as possible. This is not illegal as it's just a passively listening object per my understanding. It's also really cute :3

THIS IMAGE IS NOT MINE. THIS IS AN EXAMPLE OF HOW IT MIGHT LOOK LIKE. I took the image from pwnagotchi.org as well!
