Homemade adjustable DC power supply
I was at my parents’ house this holiday and I wanted to power some small electronics project but found myself without a DC power supply. So I decided to build my own using a simple LM317. The input is a 12V, 1A wall wart, adjustable output voltage from 1.7V to 10.3V. This should be able to power most electronic projects that require low voltages.
