Making a circuit board and components
Everything starts with making my own circuit board. I got positive photoresist boards and made my own with a fluorescent light. You need a positive developer, such as sodium metasilicate pentahydrate. Then, I used Ammonium Persulfate in an etching tank and agitator. The result is below. If you need electronic parts, Digikey and Mouser are good sources. There is always Ebay.
