thingiverse

Issue: PSU high voltage contacts are fully exposed, without an AC on/off power switch. Solution: Add a cover to the PSU, include an on/off switch, and install placeholders for future Raspberry Pi upgrades (two options for vertical and horizontal mounting). Total Budget: Approximately $3. Bill of Quantities: * AC Power socket with switch and fuse: http://got.by/3jt6h4 * DC-DC 5V 5A module, high quality (synchronous, TPS40057): http://got.by/3jt510 * DC-DC 5V 3A module, conventional (LM2596): http://got.by/3jt5qh * Four M3 3X4mm thread brass inserts: http://got.by/3jt4pc Two Designs: * One model features brass thread inserts for an extra DC-DC converter, with inserts injected using a solder iron at approximately 150 degrees Celsius. * One model includes threaded components (which may require additional threading).
