What do you do with your Altoids tins after devouring the mints? Maybe for keeping your coins, hand it over to your mom for storing the sewing accessories, for keeping handy a first aid, or perhaps keep the watercolor paint for your little niece. DIYer “Exercising Ingenuity,” however, has a very unique use for the aluminium container.
The inventive YouTuber wanted to build a fully functional Cyberdesk inside of the Altoids tin. Sounds bizarre? Surely it is, given the size of the thing. In his video, he asked himself, “That looks like a tiny computer?” It was clear from the outset that the assembly would require the utmost level of detail and sourcing all the hardware inside the tiny housing. While it might not be the most powerful machine you can own, it surely is ultra-portable and quite nice nonetheless.
Designer: Exercising Ingenuity
Normally, Cyberdesks are built inside ammo cans, rugged Pelican cases, or anything that has a boxy form factor. The machines piqued in popularity during the 1980s after the science fiction novel Neuromancer. Altoid tins have all these attributes, just the smaller size makes them a very odd proposition in the Cyberdesk world. That said, he set out anyway on putting together the hardware. For the CPU, he used the Raspberry Pi Zero W he had lying around, and a 2-inch LCD from another unfinished project. The power comes from a 750mAh lithium-ion polymer battery.
The real challenge was to find the tiny mechanical keyboard and fit it inside the small space. According to him, this was the most enjoyable part of the project, even though the video suggests it was a difficult one. It required learning how to construct the diode matrix for configuring the input, along with the assembling and soldering methodology of each of the keys. The final step here involved painting the keys with a white ink pen. Once this bit was taken care of, the DIY headed into the moderate level difficulty (at least for us). The next step was to create a 3D-printed frame to keep all the components inside the tin in place.
Wiring had to be kept to a minimum, and soldering of other components had to be done efficiently, as space was a premium. As a last step to make more room for components like the UPS HAT board and the display, the original hinge was extended with another Altoids tin hinge for a makeshift, slightly bigger replacement. Once all the hardware components were secured properly inside the tin, it was just a matter of running the system using the software. To make the thing look and feel like a vintage desktop computer, the DIYer painted the front panel beige.
