Greetings all! I've got a Handy Board with the expansion board, and the first and second digital ins (digitals 7 and 8) aren't working. 7 is stuck in 0, and 8 is stuck in 1. I replaced everything on the board but the processor itself, and I'm not (...) (27 years ago, 22-Apr-99, to lugnet.robotics.handyboard)

Kind of. Electrolytics are indeed made by plates in a conductive solution, however when the voltage increases, it pulls the plates together (standard columbs law stuff). When you exceed the rated voltage the force on the plates is enough to pull the (...) (27 years ago, 22-Apr-99, to lugnet.robotics.handyboard)

Generally, cost, accuracy, size, and drift. Ceramic caps are expensive ($/pf) reasonably stable across temperature and acceptably accurate. Electrolytic capacitors are cheap ($/pf) only moderately stable across temperature changes, polarized, and (...) (27 years ago, 22-Apr-99, to lugnet.robotics.handyboard)
