There’s something magical and nostalgic about extremely low resolution in this era of mega-megapixels on every cell phone. And the Game Boy’s big bulbous camera module just looks so cool. [Robson Couto] didn’t stop at simply using the camera — that’s been done before — but actually reversed the card’s protocol so that he could leave it entirely intact. As you can see from the banner image, it was a success.
[Robson] could read one bank of memory, but not any of the others. It turns out that the camera pack uses a clock signal that not many other cards use. It took [Robson] some serious work — a lot of it false starts and dead ends — to get this particular part working.
[Furrtek] is a person of odd pursuits, which mainly involve making old pieces of technology do strange things. That makes him a hero to us, and his latest project elevates this status: he built a device that turns the Nintendo Gameboy camera cartridge into a camcorder. His device replaces the Gameboy, capturing the images from the camera, displaying them on the screen and saving them to a micro SD card.
Before you throw out your cellphone or your 4K camcorder, bear in mind that the captured video is monochrome (with only 4 levels between white and black), at a resolution of 128 by 112 pixels and at about 14 frames per second. Sound is captured at 8192Hz, producing the same buzzy, grainy sound that the Gameboy is famous for. Although it isn’t particularly practical, [Furrtek]s build is extremely impressive, built around an NXP LPC1343 ARM Cortex-M3 MCU processor. This processor repeatedly requests an image from the camera, receives the image and then collects the images and sound together to form the video and save it to the micro SD card. As always, [Furrtek] has made all of the source code and other files available for anyone who wants to try it out.
One of the first popular mass-produced digital cameras was the Game Boy camera, a terrible black and white image sensor stuck inside a highly modified Game Boy cartridge. With a Game Boy, the camera, and the Game Boy printer, it was able to produce low-resolution but still surprisingly usable images. Combine all these parts together with the best of hacker art from [vtol] and what do you get? The Game Boy Instant Photo Gun.
There aren’t many details for this build, but it looks like this is an uncased Game Boy Brick, a Game Boy camera, and Game Boy Printer assembled into something that looks dangerous and won’t get past a TSA checkpoint. That might be fixed by repurposing an old NES zapper.
TI calculators don’t include a Game Boy cartridge slot, so [Christopher] used an Arduino Uno to interface the two. He built upon the Arduino-TI Calculator Linking (ArTICL) Library to create ArTICam. Getting the Arduino to talk with the Game Boy Camera’s M64282FP image sensor turned out to be easy, as there already are code examples available. The interface between the camera sensor and the Arduino is simple enough. 6 digital lines for an oddball serial interface, one analog sense line, power and ground. [Christopher] used a shield to solder everything up, but says you can easily get away with wiring directly the Arduino Uno’s I/O pins. The system is compatible with the TI-83 Plus and TI-84 Plus family of calculators. Grabbing an image is as simple as calling GetCalc(Pic1) from your calculator program.
So, If you have an old calculator lying around, give it a try to enjoy some 128×123-pixel grayscale goodness!
