LM317T Variable Voltage Power Supply

After searching on internet for a nice power variable power supply based on LM317T voltage regulator i decided to design one of my own. Because i don't find a good pcb design. All the files are uploaded so you can download them. PCB is designed in Eagle Cad.

Step 1: MAKING THE PCB

I used toner transfer method. Soldermask is made by painting the pcb with glass paint.

Step 2: SOLDERING THE COMPONENTS

Parts list:
10uF, 1uF, 2200uF polarized electrolyte capacitor
220ohms, 1k both 1/4 watt resistors
LM317T Voltage regulator and heatsink
3mm led
1N4007, 1N5406 Diodes
Two pin screw terminal
