2022 Cyberdeck Contest: IP00-Minus, a Daring Wearable [Hackaday]

October 4, 2022 Mike Minotti

Watch on the wrist, with all the sensors facing the camera. There's a lot of them, and a lot of wires of all kinds tying everything together.

[Rob]’s IP00-Minus watch stands out on the Cyberdeck Contest project list page; it’s clear he decided to go a different path than most other hackers, and we can certainly see the advantages. For example, if there’s no case, there’s no need to redesign it each time you want to add a module — and [Rob] has added many, many modules to this watch.

Picking between regular LCD, memory LCD, and OLED displays can be a tricky decision to make when planning out your gadget, so he just added all three. The CircuitPython firmware initially attempted to resist the trio, but was eventually defeated through patching. Jokes aside, we can almost feel the joy that [Rob] must have felt after having put this watch on for the first time, and this project has some serious creative potential for a hacker.

[Rob] has been focusing on day-to-day usability first and foremost, with pleasantly clicky encoders, impeccable performance of its watch duty, unparalleled expandability, and comfortable wrist fit — it provides a feeling no commercial wearable could bring.

Out of the myriad of sensors, the air quality sensor has been the most useful so far, letting him know when to open a window or leave a particularly crowded place. The ESP32-S3 powered watch has been quite a playground for [Rob]’s software experiments, and given the sheer variety of hardware attached, we’re sure it will bring unexpected synergy-driven ideas. Plus, it’s no doubt a great conversation starter in nerd and non-nerd circles alike.

Good things happen when you give hackers a wrist-worn watch full of sensors, whether it’s a particularly impressive event badge, a modified firmware for an open source smartwatch, or a custom piece that pushes the envelope of DIY hardware.
