For my latest electronics project I decided to make a resistor substitution box, instead of just using another perf-board I decided to make a pcb for it so I could document the process and make an instructable. I decided to do this because I have yet to see anyone do it on Instructables so I figured it would be a good thing to share. This process works well for simple circuits that do not have a lot of small parallel bus lines in them, I have done a few guitar stomp boxes this way as well.
Step 1: Materials
Materials to design and Draw the board:
-Paper and Pencil
-Tiny #65 twist bit (0.035" which is good for most electronic components)
-Dremal or pin vise to drill holes, the Dremal is the obvious winner here
-Copper clad PC board
Materials to etch the board:
-Ferric Chloride(FC), which is used to etch the board
CAUTION Ferric Chloride is a very corrosive liquid the vapor well cause steel to rust, therefor one must take all precautions nessessery in order to protect yourself as it well cause nasty burns and alike. So therefore you well also need
-Paper towels to clean up spillage
-A well ventalated work area as the vapor is also quite nasty and not good to breath in.
Aside from all the safety stuff you need,
-A small resealable plastic container to put the FC into for etching and storage afterwards.
-A larger plastic container that the small one well go into for water and storage of materials afterwards.
-Warm water, goes in larger container to heat the FC.
