    What is holding switch mode PSUs back?

    Hi Guys, Today SMPSU’s are found frequently in home electronics equipment. Almost every VCR, DVD players, tuners, TV-sets and similar has got them and so do every computer laptop or other computer. The smaller and lighter SMPSU’s are cheap to make and they save weight and space in the...

    help for rpm measurement

    I guess it’s like comparing a gallon (inp. vs US) they are not even close! Or a ton vs a tonne and a ton! Or short ton = 907.2kg vs metric ton = 1000.0000000000000kg how stupid is that?  ;D I stay with metric like Europe; it’s much simpler this way! 8) Or perhaps one day there is only 907mm on...

    Timer

    Hi Herman, I do not have Eagle installed in my computer; you can (while Eagle displays the circuit) make a screen dump (Prnt Scrn key) and post it here.  8) For the future (wouldn’t have helped in this case but); if you have a file with a suffix not allowed (like .sch) just ZIP or RAR it and...

    3 Minute Timer

    Hi Jim, Your local electronics store might have a kit for you. Most simple timer kits use the 555 IC instead of the CD4060 which I prefer, but still it works as a timer.

    3 Minute Timer

    To power the timer a small PP-3 and a low drop regulator like L4940 or similar would be fine, this will keep the timer run exactly right each time. Here are a few examples on CD4060 circuits, of which some are very well explained: http://www.circuitsonline.net/circuits/view/106...
