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 $$T=5R_{LED}C$$

Simplest analog computer

In this post I will show you how to make a analog computer using just resistors, switches and a 100 micro ammeter. Here’s the schematic of it: You can see the idea on how this analog computer works, it uses ohms law to get current from resistors in the circuits. Each current is limited in

Icon Screensaver

This screensaver does exactly what the name says. It looks for icons and have them bounce around the screen and leaving a trail behind them. They are randomly chosen from windows, system and cursors directory. It uses ExtractIcon function from shell32.dll to get the icon and number of icons.
