Re: Really understanding Capacitors

Hi Dale -- . I would like to throw some light on the subject if I can. As I see it, there are three areas up for discussion - . 1. What's involved in triggering a 555 on pin #2. 2. Why the charge/discharge differences. 3. About coupling capacitors . 1. It would appear that you are setting up a strin...

Re: air conditioner pre cooler

I lived in Barstow, Calif. from 1973 to 1987. Swamp cooler worked great after I made some changes. The cooler was roof mounted so I removed the ceiling grating at the end of the hallway, opened the attic inside trap door at the other end of the hallway and cut a large opening in the attic portion of...

Re: use of 1/4w resistors to control a dc motor

Bob Scott: i couldnt find any other values for the motor other than the max rpms, :???: cant - One thing you should try to do is find out how much juice the motor uses at stall or near stall conditions. A quick and dirty way to do this is with a home made pony brake (the motor is small so this will...

Re: Time Base

Maybe my programming knowledge is behind the times, since I still use various versions of basic. The attempts I originally made were to use a loop to count the 60hz pulses with a branch to a 250ms output pulse routine when the count was satisfied, then back to the counting loop again. Obviously, wh...

Re: Appreciation for Ma Bell

I've noticed that myself, in storms I've lost power, cable. water and so on but not once have I lost phone service. It would be nice if they shared their secret with other utilities. :wink: Hi SETEC - Back when I worked for Ma Bell (and back then it WAS Ma Bell) in the California high desert, we wo...

:razz: Hi Roger. (time is 4:22 p.m. local) If this engine is for display, don't forget to change the valve springs to something much lighter - just enough pressure to keep the valve closed on the cam's base circle but light enough to be able to push the valve open with your finger. Removing the spar...

This is a very small, battery powered device- no AC available here. The 12 VDC relay is driven by an 18-pin DIP IC. Without the cap across the coil, and a cap across the motor, a large battery still results in chatter. The supply voltage is not dipping- the relay drive is being chopped by RF interr...
