Electric Power Steering solution

Hi, I built a project vehicle ( picture a Kawasaki Mule ect.) I am upgrading the steering to a 2004 Saturn Vue (KOYO) electric power steering unit. It is a niece compact unit. Problem: I was going to use a 555 (not ready for PIC's yet) and send a dummy VSS signal. Well it use's 2 class 2 serial data...

Re: Really understanding Capacitors

The cap values in uF are: 0.1 - 0.05 - 0.021 ( the best: 5 mS and 3 volts) - 0.033. In both ceramic and mylar the behavior is the same. Construction is breadboard. I have pulled the bottom plates and looked for broken jumper pieces shorts ect. Everything is O.K.

Re: Really understanding Capacitors

Hi Robert, I am reading the cap at the second 555's trigger input which is tied to Vcc- 5 volts via a 10 K resistor. Pulses are between 5 and 10 milli seconds to the maximum negative value in a nice straight line. Recovery back to Vcc becomes very anolog and the time varies. I understand the non pre...

Really understanding Capacitors

I am building a shift circuit that utilizes 555 timers. One triggering the other by way of a mylar cap. 555 triggers can be touchy, so I wanted to transfer a good " pulse". After all my reading and studying I realized that I really have no understanding of how to pick a capacitor properly for this c...
