Sinclair ZX Spectrum & QL OqtaDrive Standalone v1.2b PCB
PCB for OqtaDrive that combines the main circuit shown on the github wiki with a Raspberry Pi for standalone usage. This is an updated version of the v1.1 PCB adding circuitry for a vibration motor which provides feedback when loading etc... I've also removed the two LEDs preferring to go with a single bi-colour LED which better fits in the original case.
The PCB will fit in an original Sinclair Microdrive case (with a simple 3D printed bracket to secure the top) and receives all necessary power from the Spectrum or QL via aTSR-2450 9V to 5V converter. Full set-up shown in the following diagram:
Full write up on setting this up can be found on my website
A bracket to fit this in an original cast can be found on Thingiverse
Video of it working can be found on YouTube
