Technical question about good low power rail to rail opamp Technical question about good low power rail to rail opamp. I published 'scope_pic' http://panteltje.com/panteltje/pic/scope_pic/ and am getting questions as 'to where to connect the input etc..'. The question is how to make a 1 MOhm, few pF, input with a bandwidth of about 1MHz, with as few components as pos... 14 Apr 2010 02:14
Could lightning flashes damage a camcorder ? Hello, I am thinking about purchasing/ordering an "expensive" camcorder... with sound option too ! ;) :) I might use it sometime to film a thunderstorm... I am wondering if such "thunder flashes" might damage the camcorder ? Like a human's eye staring into the sun for too long ? Can a camcorder be dama... 18 Apr 2010 07:34
You'd think someone would make... When I travel I carry one of those Buttoneer gadgets that "staples" a button back on using tiny plastic straps. You'd think someone would make a similar device for fixing a pant's cuff that comes unstitched :-) Is there such a thing? ...Jim Thompson -- | James E.T... 18 Apr 2010 17:31
jfet as current source, temp dependence in-theory question I've not used JFETs before and was thinking about them first as high impedance current sources to get started learning more about them. (I already gather that their potentially very high input impedance and low Ciss is a good thing and I'm broadly aware that FET and BJT input opamps divide their world into low ... 12 Apr 2010 14:47
LED temperature range Hello, I've been asked to design a simple motor-driven pump for medical use, and one of the primary requirements is that the device can be sterilized using an autoclave, which works with steam at 135 degrees Centigrade. Basically, there's no need to use any semiconductors or electrolytic capacitors in the devi... 14 Apr 2010 00:02

UART Multiplexing "eeboy", Are you just a shill trying to "seed" your web page hookup to this usenet thread? You want to apply LOTS of engineering time because a $2.70 part is too expensive for your one-off project? What you're describing is an electronic version of an A/B switch, correct? Why wouldn't 9600 Baud do the job?... 12 Apr 2010 07:00
