goofy PWM


May 29, 2015, 1:20 am

I need an isolated analog output (many of them, actually) with, say, 1 PPM programmability and linearity. An optocoupled DAC would be silly, so I'll use PWM. https://dl.dropboxusercontent.com/u/53... Read more »

I seem to be having a networking problem that only lets me reach www.google .com and groups.google.com. I can't get to mail.google.com or any other we bsite I have tried. This is the same in all ... Read more »

Experiments towards a differential air pressure based wind speed sensors


May 28, 2015, 4:08 pm

Do not remember who mentioned it here, but why not try it I though: Got some of these absolute pressure sensors (barometer): http://www.ebay.com/itm/201116533872 And the 24 bit ADC with 128x gain... Read more »

lessons taught


May 27, 2015, 7:24 pm

I think older people neturally want to teach. That's a tribal, selfish-gene survival thing. When something in a new circuit doesn't work, people are sometimes inclined to replace a bad part. Most ... Read more »

USB Serial Adapters from eBay


May 27, 2015, 4:40 pm

I have bought a number of serial port adapters from eBay over the years and many claim to use Prolific or other name brand chips when in fact they are counterfeit. I bought one batch after speci... Read more »

PWM generator for half Hbridge

  [ 2 ]
May 27, 2015, 10:28 am

Hi everyone, we are facing a stupid issue with our current signal generator (Agilent 33500B). We are generating, via GPIB, a complementary PWM signal [1] with time delay insertion in order to ... Read more »
