Choosing a PIC controller
Hi, I have been reviewing farnell's shop to get an idea of existing PICs, but I am clueless regarding which one i should choose. The PIC is connected to an accelerometer (input) and has 2 outputs, one that is either 0 or 1 (solenoid command) and an additional EEPROM to store measurements from the accelerometer... 5 Mar 2010 19:37

Follow up on the Stepper Question: H-Bridge
I had posted recently about stepper motor control. Since that post and the replies I received I have come to the point of building the actual motor controller. Plenty of H-Bridges exist but I wanted to use some components I had. I posted this on my first posting but received no replies; with all the spam I see s... 13 Mar 2010 14:14

Discharge a huge voltage
hello, I have a very simple circuit here, I am charging a 900uF capacitor to 600v. (900v max capacity) I want to discharge this at 0.01seconds interval. I have 30 ohm resistance, without so from my calculation I should have 20 amp max. All this element are in series with each other, I want to add a transistor... 5 Mar 2010 18:29
