Small variable PSU with LM317 / LM337

It comes in handy to have a small PSU with variable output voltages around to test modules with different voltages or drive small projects. The emphasis is on driving small projects. Tests are better done with a lab PSU. I just made a small PCB for a +/- 12..17V with LM317 and LM337. There is nothing special about it. Straight forward design. Because it is small the heatsinks are not that big and close together. Don’t drive it to hard.
