Power Supply - Part 1

Hey folks, how are you?
So, some time ago in one of my classes we soldered a small variable power supply, I has in the need of one anyway, but unfortunately the supply had a lot of noise, I tried to use the ADC of an atmega8 and a LM35 to check the temperature of my room and the temp has varying considerable more then when the power was coming from my usb port.
And it was a pain to have to adjust the power to 5V everytime, burned a chip because I forgot to do that…
So that is why I decided to use the transformer from the old board and make a new board with a regulated 5V output and a variable output also. And since I was gonna do that, might as well do a decent enclosure.
