Low Capacitance Tranzorb in the 10-30V range
Gents. I'm looking for a tranzorb or equivilent that can discharge a 45mH inductor with 1A DC flowing through it if one end gets disconnected. This tranzorb must have less than 100pF of capacitance. The tranzorb will be in parallel with the inductor. any thoughts? All if the 1.5KE like parts have 800pF a... 2 Feb 2010 16:26

motor driver boards
Can someone recommend an off-the-self solution for a motor driver board? I've found a few that are close to what I need but none are quite exactly the solution I'd like. For example here are a few I've found: http://www.pololu.com/catalog/product/758 http://www.roboteq.com/brushed-dc-motor-controllers/brushed-... 2 Feb 2010 16:27

Fixing a Maxent MX-26x3 LCD TV
I have a non-working Maxent MX26X3 LCD TV/monitor. Immediately upon powerup, it will generate anomalous vertical multi-colored lines throughout the entire screen with a blue background. I've read about two known solutions, and I think both are related to one root cause. On FixYa, people have reported favor... 27 Jan 2010 03:46

Hysteresis on dsPIC ports?
Hello, This really blows my mind and I think I've arrived at the decision not to use their uC in the future. But a client does. It's a dsPIC and while the datasheet says that the IO ports have Schmitt characteristics there is no mention of how much hysteresis. So, I dutifully opened a support ticket asking f... 27 Jan 2010 19:28
