Overview
I started LPS during the 2006 summer althought I had this idea for a long time. Every electronics lab should have some power supply that you can adjust and use. I needed one and it's also one of the thing most eletronics hobbiest like to do. LPS will probably have the following specifications:
- 0..18V/2A
- A positive variable power supply with a full voltage scale digitally controlled (8-bit resolution). The output current is measured and is also limitted.
- +12V/2A
- A fixed 12V output with a maximum 2A load. The output current is also measured and limitted.
- +5V/2A
- A fixed 5V output with a maximum 2A load. Likewise.
- -12V/2A
- A fixed -12V output with a maximum 2A load. Likewise.
- 0..-18V/2A
- A negative variable power supply.
LPS will also feature:
- Measure of output current and voltage
- Recording of these measure over time
- An USB connection for a remote control and monitoring
Architecture
In its heart, LPS will probably have 3 to 4 Atmel Atmega8 microcontrollers that communicate with an I2C bus. Why so many?
