Been a while but have had a busy year. Amongst the odd projects that I’ve been working on is a power converter for the Sinclair QL. The original power supply is fairly hard to get and its unique power connector means that there hasn’t been an off the shelf alternative – until now.
The converter takes a nominal 12V input from a customer supplied power supply (plug pack or other suitable power source with a 2.1mm DC plug) and converts this single voltage into the DC and AC voltages the QL requires. The converter comes with a custom 3D printed case and QL power plug.
Protection is provided with the converter returning to standby if excessive power draw is detected or if the external power supply is of insufficient power rating.
