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!

This weekend I finally got around to releasing v5.0.0 of the Arduino LMIC (https://github.com/mcci-catena/arduino-lmic). This is an independent very lightweight implementation of the basic LoRaWAN protocol, originally done by IBM Zurich, then curated for many years by Matthijs Kooijman. 1/

I decided to swap it with a Bluetooth module. But first, I cut a perfboard to fit into the free space next to the motor shield. Soldered the pins and a pin header for the module, including resistors for the voltage divider.

New long term project...
I got this talking #DrWho 50th anniversary UK #Dalek #model quite a few years ago, and thought I could enhance it a bit.
I opened it and already bought some motors. First goal is to make it move on its own.
For now, I'll use the #ArduinoMega2560 #microcontroller that I got for my birthday, and assembled an #Adafruit motor shield with two motors. I hope to make the head turn, too, but will have to find out how to open it further.

Did I ever show this? Turns out because #ESP32 has super-configurable pins AND because the #adafruit #QTPy / #Seeed #Xiao format has castellated pads, you can just solder an I2C OLED display right on top of it and it works! Since this is an #ESP32S3 QTPy, I use this to test #CircuitPython WiFi stuff. Lately I've been using its as a Multicast UDP emitter 😀 Code for this demo: https://gist.github.com/todbot/31272a914df7f856b088671943b5ed35

It's the most useless #DTMF phone dialer! Only sequential numbers allowed!
(this is a test bed for doing multicore stuff on the #ESP32: #Mozzi audio synthesis in "loop()" on core1 and UI stuff on core0). Uses a @adafruit QTPy ESP32, a #PCM5102 I2S DAC, and a #SH1106 OLED display #Arduino code: https://github.com/todbot/mozzi_experiments/blob/main/esp32_multicore_mozzi_dtmf/esp32_multicore_mozzi_dtmf.ino #adafruit #qtpy

@todbot oooh yes that makes sense! I've been using a lot of the tiny #QTPy boards from #Adafruit, and they have been #making charge boards, neoPx boards etc to all go together. I'm just loving them!

It's not a bad likeness, I think. Apart from the fins. I need the fins to keep pointy end up, flamey end down in the absence of vernier rockets and thrust vector control, though.

This is my scratch built 3D printed, flying model rocket semi-scale replica of the Gilmour Space Eris, with camera and altimeter.

Mechanically it is the most complicated thing I've made so far. 12 3D printed parts plus the electronics, parachute and shock cord. The electronics are pulled out of my previous rockets. I did put an extra slot in the avionics tray though, so I'd have space to add an inertial measurement unit later. The airframe goes together with bayonet couplings. Total mass (without motor) is 127g.

Hopefully I'll get to fly this soon, but the weather forecast isn't looking fantastic.
