Welcome to KAMPi! My Self-Built Digital Camera

Hello everyone! I have always wanted to build my own digital camera. But not just any digital camera, one I would actually use like a regular point-and-shoot camera. I wanted something that would give me traditional feel, but still shoot in 4K. A tall order for sure, and to top it all off, I wanted to build everything myself. Well the time has come. . . Please join me in welcoming KAMPi! Check out my build below.

Why KAMPi?

KAMPi is short for “Kampay” which is Tagalog slang for “Kanpai” the Japanese word for cheers. It also sounds like CAMPi another way of saying Pi Cam, which is exactly what it is – a digital camera built using a Raspberry Pi mini computer.

What’s Inside?

I built KAMPi from the ground up: selected, wired, and soldered the hardware electronics, 3D printed the parts, and prepared the software.

For the computer internals, I chose to use a Raspberry Pi Compute Module 5 which rides on a Waveshare Nano A. The camera imager and lens are from Raspberry Pi as well, the Raspberry Pi High Quality Camera with the 16mm Telephoto Lens. For the display I used a Pimoroni HyperPixel 4.0″ Hi-Res Display. The display is connected to the Waveshare Nano A via GPIO pins (the header of the Nano I soldered myself). Everything is packed together in a tight package shown above.

For the power electronics I chose to use a Pimoroni LiPo SHIM I purchased from Adafruit. I wired it up with a on/off switch and connected it to a USB-C plug.

For the trigger mechanism I chose to use Adafruit’s KB 2040 electronic board due to it’s small form factor, and also that it works over USB-C / USB serial. I also chose to use the KB 2040 because the HyperPixel 4.0 uses all the GPIO pins of the Waveshare Nano A and USB-C / USB serial seemed like a more straightforward alternative. Alternatively I could have used I2C, via the HyperPixel 4.0, but I didn’t have enough time to go that direction before the convention. The trigger itself is an illuminated pushbutton switch also from Adafruit.

I’m no expert in 3D printing and I originally wanted the form factor to be smaller. But since the camera cable stuck out from the top, I needed to make extend the base.

So I designed and 3D printed a cap portion to hold it all together.

I even added a hinge and latch lock to for easy access.

For the software, I wanted something simple. I’m running python script to take the photos. One thing to note is that the camera does not have any autofocus (which is exactly how I wanted it). That meant I needed to see what I’m shooting before taking the photo. I added a preview in the software, so I could focus the lens, and then take the shot.

The desktop above shows the camera python script and the folder where the photos are saved. You can also see the Circuitpython mounted “disk” of the KB 2040 on the desktop. I’m also a space nerd so I chose a James Webb galaxy image as a backdrop to show off the beautiful Pimironi display. I included a fun logo and added a nice rectangle so I could easily see the program icons on the desktop too.

KAMPi in Action

KAMPi is so new, I haven’t been able to test it in the wild yet. But here are some raw unprocessed photos from my home test shots.

More to come from Opensaucelive!*

Tomorrow is Opensaucelive 2025 and I thought what better place to test and share my build there. Wow, I’m so excited to share KAMPi with everyone at Opensauce. If you see me, please do say hello. I’ll also upload some photos from KAMPi at Opensauce below:

[*UPDATED July 20, 2025] See above sample photos I took at Opensaucelive 2025 using KAMPi. I chose the sharpest in focus images to share. Since it was my first time shooting with it, many of the photos came out blurry – which was exactly what I was expecting! I wanted KAMPi to emulate the feel of a film camera, capturing the moment. And KAMPi did just that. I’m also sure I’ll get better at taking photos with KAMPi with a litter more practice 🙂

[*UPDATED Sept 20, 2025] Updated the description of the KB 2040 to provide additional info on why I decided to use it over I2C.

Kampay (Cheers) for now!
