In this blog I will show you how to make a dip switches capacitor substitution board. Its very simple since capacitors add up in parallel. So if you look at the schematic you will get an idea.

Capacitor powered LED flashlight
Long time ago QVC sold a shakeable Flashlight that had no batteries just a shakeable generator and a super capacitor. This flashlight uses a 5vdc 1.5a wall wart to charge the capacitors. To figure out how long it will take to charge the flashlight you use this equation $$T=5R_{currentlimit}C$$ And for total discharge time $$T=5R_{LED}C$$ …
De Sauty’s Bridge
This bridge is good for measuring Capacitors. What you do is hookup high impedance headphones to the output(V2 in the NL5 Circuit). Then adjust the resistor(s) , you can use the calculator below to find a suitable resistance for the resistors. This works like a Wheatstone bridge except one side has capacitors. The calculator calculates …
