# LPSU – Linear Power Supply
A simple ±12V linear power supply, which supplys max 1.5A on each rail. This PSU should deliver enough current for 2 rows of 84HP.
## ⚠ Safety Warning
**DANGER! To build this power supply you need to work with 230VAC from mains. This can kill or hurt you badly! If you wire the transformer wrongly you create even more deadly high voltages. The capacitors in the circuit can keep their charge for minutes, even after you plugged everything out. They won't kill you, but the charge can burn/vaporize your tools if you create a short circuit. If you are not sure what you do, ask for help. Don't make stupid decisions!**
## Circuit
![images/simple_psu_schematic.png](simple_psu_schematic.png)
The Circuit is based on a Toroid transformer which converts 230VAC to 15VDC (this value is the effective value, The peak-to-peak voltage is roughly 42Vpp). The four diodes D1, D2, D3 and D4 form a bridge rectifier – a circuit used to convert AC voltage to DC voltage. With this we can convert positive and negative halfwaves of the two sine voltages of the transformer's secondary windings to DC (roughly 20VDC).
The Capacitors C1 C2, C9, C10, C11 and C12 are used to smoothen the DC coming from the bridge rectifier. The LM317 and LM337 are Linear Voltage regulators, which allow us to set a precise voltage level with a voltage divider (replace R3+R4 and R6+R7 with 10K Trimmers). The Diodes D5, D6, D6 and D10 are there to protect these ICs. Make sure to use heat sinks for the Voltage regulators, because depending on the current draw of your modules they may become very hot or even destroy themselves otherwise.
Adjust R5 and R10 to fit the used light diodes and desired brightness.

The LEDs glow and the PSU is calibrated to 12V with the multimeter.

# Minicase
A small Eurorack Case with 88HP on two rows. Adjust the 244 mm width to fit the width of your rails. Look at [Doepfer's Eurorack Construction Details Page](http://www.doepfer.de/a100_man/a100m_e.htm) for further information about rack units and standards.

# Simplecase
The most simple implementation of a eurorack case possible. For details to single parts read the [diy case wiki entry](https://code.hfbk.net/t6/sdiy/wikis/diy-case)
This uses:
- 85HP rails from Reichelt
- A 65 Watt Meanwell RT-65B powersupply
- A Clicks & Clocks Busboard without 5V option
## One row
### Pictures
![Simplecase view](images/simplecase_persp.png)
The simplecase consists of 5 case parts:
![Simplecase Exploded view](images/simplecase_exploded_anotated.png)
### Size
All units in Milimeters (mm)
Choose the thickness to your taste
The depth of 150mm allows to use average modules in the vicinity of the powersupply. If you wanna go for something less deep check yourself how much space would be left. If you wanna go deeper change the 150mm for the parts Top/Bottom and Side to the desired value. Note that this is the INSIDE depth.
