Steps
1. Collect Parts
Make sure you have everything in the parts list.
You can get the PCB by going to BatchPCB and submitting the GERBER files above for processing.
3. Solder IC Socket and Resistor
Solder the second resistor into place. Solder one of the socket legs in place. Then use one hand to push the socket all the way into the board while using your other hand to re-melt the solder on the socket leg. This way you can make sure the socket is well-seated. Continue by soldering the rest of the socket legs.
4. Solder LEDs
The LEDs can be solder into either position. It doesn't matter because both LEDs are lit simultaneously. Match up the flattened sides of the LEDs with the artwork on the board. (Ignore the + marks by the LEDs. They are wrong.) Solder the leg closest to the edge of the board of each LED. Then adjust the position of the LED by pushing it flush with the circuit board while re-melting the solder. Once the LEDs are positioned properly, solder the remaining LED legs.
5. Solder Battery Clip
Solder the battery clip to the back of the board. You may have to push hard to get the battery clip into the holes for it. You do not have to fully insert the battery clip. Just make sure that your solder makes a secure contact between the leads of the battery clip and the holes.
