Making a Canon EF Lens Mount for a Game Boy Camera @NintendoAmerica #Gameboy

Bastiaan Ekeler wasn’t satisfied with the camera on his Game Boy. He states:

I was inspired by Tim Binnion‘s work with the Game Boy Camera and a cheap cellphone tele lens. I figured I’d up the ante and design and build a full Canon EF Mount for my Game Boy Camera. The GBC has a sensor size of about 3.6mm² which seems equivalent to a 1/4″ sensor (Wikipedia). This gives the GBC a crop factor of about 10.81. With my 70-200 f4 mounted on a 1.4x extender, this gives me a max equivalent focal distance of about 200×1.4×10.81=3,026.8mm.

3,000 mm, insane. He captured the shots to his PC using the Arduino Gameboy Printer Emulator by Mofosyne (github). He cut a $5 Game Boy Link cable from Amazon in half and soldered it directly onto an Adafruit prototype shield plugged into an old Arduino Duemilanove. Serial data comes in from the Arduino in HEX format and can then be converted to PNG files using a JS script. When transferring multiple photos at once, the resulting file is one tall PNG reminiscent of analog camera film but can easily be sliced in Photoshop.

And the results:

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
