Modern smart watches have some incredible features, but they still don’t stack up to what science fiction promised us, both in size and capabilities. Fortunately, [Zack Freedman] has set out to change that with the Singularitron, a modular wearable computer that is less Apple Watch and more Pip-Boy.
The most striking features of this monstrosity is its size and the out-of-production four-line VFD display. The inputs consist of a row of large RGB-illuminated buttons and a rotary encoder mounted at an angle to curve around the wearers arm. On the inside are a pair of PCBs with an integrated Teensy 3.2, BLE module, motion processing module, haptic driver and power circuitry drawing from a removable 18650 battery. The armband is from a commercial wrist mounted barcode scanner which attaches to the Singularitron with a quick-detach mount.
