Step 5How to Solder
If you are experienced with electronics, skip this step.
If you have never done something like this before, here are some tips that I learned to do (and not to do).
-Use a small piece of perf board. I fit this entire circuit (without the switches) onto about a 1X3 inch piece easily.
-Lay the circuit out on the piece like it is on the schematic. It will be reversed on the bottom, but I'm sure you can figure it out.
-When soldering, NEVER touch the solder to the soldering iron. Hold the iron to the wire and let it heat up. Then touch the solder to the wire, and let it be wicked up and down for a good connection.
-For this circuit, you can attach the terminals directly to each other instead of wiring a tiny gap. Just bend and solder. Be careful though!
-Attach all grounds to one copper wire soldered to the perf board. It makes everything ALOT easier.
-Make sure your grounds are connected very well or else you will get a loud buzz.
-Get some desoldering braid. That stuff is very useful! I couldn't have done this project without it.
Practice, practice, PRACTICE! The op amp can be cooked if you hold the iron on it for very long. Try cutting a little piece of perf board and solder wires to it and then desolder them. There is nothing worse than going through the entire process to find out the project doesn't work. I know. I did that twice (different designs).
Look at the second picture for what the soldering should look like.
