Re: Dumb thing of the day ...
Quite the masterstroke ;-) I have some adjustable wall-warts with exchangeable plugs. The voltage is unregulated of course and not much current, but they work for such stuff that has a regulator on

Re: SPI interfacing - How long can external connections be?
Well, I know for sure what won't work! I had a 100' spool of 24 gauge solid core wire handy with both ends of the cable exposed. I stripped off some conductors, spliced it into the bread board circuit

Dumb thing of the day ...
Hmm, Working alot between my bread board and the programming board for my project, I got fed up with the mess of wires. I was using the power supply on my little machine for powering the programming

Research papers? Nope, never saw any of them around here... Dunno if there's "new" information or not, you might be better off looking elsewhere for that. In the meantime, if you (NOT "u") have any

Re: Favorite CMOS binary counter
For up/down counters try the CD4029. 4000-series CMOS is real pokey when it comes to speed. This is good. It simply cannot narrow noise pulses that would give false counts when using faster IC logic

Re: datasheet
I've used them a lot. But recently they decided that they were going to add a page to each datasheet, making the indicated size and page count wrong, so that means more time to download, more space

Re: datasheet
Thanks for the offer, but Shawn Upton sent it to me via email and I can read it all just fine. Something about me and the connection to that site, I don't know what the problem was...

The printers are on a lan printserver. But i was thinking about getting a LPT from the PC to the electronics bench for micro programming. It works fine with 2 extensions right across the room, but i'm

Re: USB cable length
Isn't that strange :-( It used to be you would use a serial interface because it allowed for greater cable lengths. Parallel interfaces like the printers were problematic over 10 feet whereas RS232

SPI interfacing - How long can external connections be?
Hi Guys, Having lost enough hair trying to get i2C working with BASCOM, I dropped it and switched to the SPI interface. Got that working within a couple of minutes as opposed to countless hours

Favorite CMOS binary counter
A very knowledgeable person has suggested that I uses a CMOS binary counter to set up a circuit used to test my SMPS. I need to take a look at Digi-Key or Mouser and select a binary counter. I think
