Speaking of atomic clocks for the home... I have several atomic clocks. One is a wall clock (time, temp, date, moon phase), another is a weather station with a clock, a clock radio with atomic clock setting, and an atomic watch. All of these will "sync up" sometime after midnight. You can set them ...

Janitor Tzap: Yes it was purchased from Radio Shack, you think that has something to do with this? Well..... Radio Shack has a bad habit of buying up; used, old stock, or rejected parts. Then re-packaging it, and then re-selling it. Most of the time the parts are good. But once in awhile they get a...

Clearly it shows roughly a 10sec delay for R=1Meg and C=22uf (or near that anyway). The data sheet is for LM555. Mral, Not all 555 timers are created equa...

I found the copper wiper that is attached to the plastic slide had snapped off. I made several tries to re-attach it. But it just kept snapping off w...

Quasar VCR Problem Solved......

I got in an old Quasar VH5251YW.{Circa; 1985} With a problem with it being stuck in rewind. I can't find a service manual for it. I've already tried Sams PhotoFacts and came up with nothing. I know Panasonic and RCA have used this same chassis for they're own VCR's. So, I'm trying to find one of the...

Re: Question about the CD back-issues (Servo, N&V)

I'm looking at replacing my space-expensive paper copies with the CD versions now available. I REALLY like the PDF format for magazines, but for magazines with projects in them that require support files (either source code, PCB patterns, or whatever), are they included with the CD? Or is it exclus...

How is the Television connected to the Cable Box? RCA Cables? Left, Right Stereo & Video Cables? S-Video and the two RCA Left & Right Cables? Have you tried just connecting a Antenna to the set, and check for broadcast signal? If It works ok on Antenna. Then I would say you have a problem in the vid...
