RackPi PowerSupply Unit 19" 2U for 7x Raspberry Pi

thingiverse

I've decided to simplify the power connections of my Pi's and eliminate the need for single external power supplies. This Power Supply Unit allows you to provide power for up to 7 Pi's, featuring a main voltage connection with a power switch and individual switches for each Pi. The electrical circuit is straightforward: input power (+) connects to one connector on each switch (via pin header and jumper wire), while the other switch connector has a link to a screw terminal (again with an jumper wire) and also a resistor in line. The ground connection (-) terminates at another pin header, where LEDs and second pins of screw connectors are connected. A Micro USB cable can be easily connected to power your Pi's with 5V. To power up or down, simply flip the switches - that's it! The green indicator light shows you which switches are active. Here is a list of materials needed: * 7x LED 3mm Green * 7x 1.5K Ohm Resistor * 7x Power Switch (small) * 1x Power Switch (large) * 1x Power Supply 50W 5V * 7x Micro USB Cables * 8x Screw Terminals * Jumper Wires * Solderable Pin Header * 1x Circuit Board * Screws and Nuts * 1x Power Cord Here are some example links for the materials: LED 3mm Green: https://www.reichelt.de/led-3-mm-bedrahtet-gruen-3-2-mcd-60-led-3mm-2ma-gn-p21624.html? 1.5K Ohm Resistor: https://www.reichelt.de/widerstand-metallschicht-1-5-kohm-axial-0-4-w-1-vis-c1501fc100-p237121.html?
