Updated: 2010-03-11 00:27:03Hi I was wondering if anyone could look at this and tell me what I might be doing wrong, I seem to have killed the transistor. I was running it...Learning resources for Electromagnetism?
Updated: 2010-03-10 23:41:41I am taking class in my university on electromagnetism (2nd class). At the moment we are covering electromagnetic wave propagation. I feel like I...How would you define VOL and VOH of inverter?
Updated: 2010-03-10 22:16:47I'm learning about inverters and I know that when: Vin = VOL, Vout = VOH & Vin = VOH, Vout = VOL However, what is the meaning of each of them?...level shifter from +5 to +/- 2.5
Updated: 2010-03-10 22:16:07Hi, I am trying to build a +5v to +/-2.5v voltage shifter for my ramp waveform (from MCU). I looked at similar threads but they all seem to be + to...ULN2803 DC Motor Control

Updated: 2010-02-18 19:43:00In order to get more out of your CV1 input on your VoS synth, we have come up with a simple mod that will help you do more with your synth. The mod should take only about 15 minutes and requires adding a new wire and moving an old one.
