− | + | It seems to be believed that runing a driver with too little load can damage it. A possible solution is to use a capicator ( EL wire behaves as a capicator ) as a dummy load to be switched on when the length of wire dirven is too short. | |

− | Probably. The lower the freqency the the more we can be sure of it. The blending is done in the eye, 24 Hz is normal for movies, so this or faster might be a good starting point. Motion can make the modulation more obvious, so a frequency somewhat higher might be better. Need the frequency to be low enough so the width can be controlled accurately and to leave computation cycles for the controller | + | Probably.

Seems like the popular answer is to use a triac, driven through an optical isolator if you think the mc needs a lot of protection. | Seems like the popular answer is to use a triac, driven through an optical isolator if you think the mc needs a lot of protection. | ||
