Back in the early days of computers, (before 1980) if you wanted to add a serial port to your computer you had to buy a UART and find a way to generate a baud...
... Look at the 74HCT4060 or 74HC4060; this is a 14-stage divider with an oscillator that can work with crystals. For a typical 16x baud clock for 4800 Hz,...
The final baud rate is 300 the clock going into the 6850 chip has to be 4800 Hz. The LM555 runs at 9600 Hz. The flip flop divides by 2 and makes the wave...
I recommend buying a pre built programer. The one I use is the EPIC from Micro Engineering Labs http://www.melabs.com It only cost $60 and will program all...
... Sorry, I misread your numbers. Are you sure you need 9600 Hz? (that'd be 600 bps for a UART that requires a 16x clock). The 6850 could work (as I recall)...
We're not talking a general purpose IBM PC with 640k or RAM here. We are talking about an appliance that has a small computer system in it. It runs on a...
Hello: I've recently been working on a Mini Sumo Robot, so I'm interested in finding out when competitions will be held in 2003. I can find plenty of...
For the money, I would recommend using a PIC. You can program it to generate several timing waveforms on its output pins, and drive it off the same clock the...
Hello I'am trashing a bad EtherNet Card. I think some one on this group once made a remark that there is a voltage converter on the card. I tried doing a...
... Maybe on your card, though I don't recall seeing such a thing. Hmm... now you've got me curious. Looking over my old NICs, I see the following potentially...

What you are referring to are the older coax thin ethernet cards. They have a 5v to -9v DC/DC converter on them. This is to power the transceiver chip which...

Happy New Year to all, I am searching infos about building a quad encoder into a hacked r/c servo. AFAIK no info about it is available on the internet. I would...
Sounds like your plan should work fine assuming the CNY70's are photo-reflex sensors (i.e. have both an LED and a phototransistor). Cheers! ... From:...
