My favorite IDE

This is an old post, nowadays I use a web IDE. We all start with something like notepad++ until we start for something more useful.

USB bike charger

Before the era of solar chargers, people could charge their phones via their bike dynamo. Phones back then charged at a maximum of 500mA, which is close to the 400mA a regular bike dynamo generates. Nowadays phones require lots more power. A video of this board can be found here. What you’ll need: 50x100mm board 4 diodes 1n5817 (in order of preference: 1n581[7,8,9] or 1n400[1,2]) large capacitor: 10-35v, 750-1000uf small capacitor: 10-35v, 10-24uf 7805 (don’t get the small 100mA) What you need to know: Read more
