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 The attempts I originally made were to use a loop to count the 60hz pulses with a branch to a 250ms output pulse routine when the count was satisfied, then back to the counting loop again.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...

:grin: Hi guys! What you are talking about has really got my interest. If you'll allow me, I'd like to toss a few ideas out there for your perusal. I grew up with generators in cars before they switched to alternators - (I switched to alternators to be more specific!). When the generator on my '62 C...

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...
