Smallest Transistor - 7 atoms across Not seen mention of this here yet but the first electronic switch transistor built by moving atoms around is now just 7 atoms across. Makes you wonder how they do the phosphorus doping! <http://www.telegraph.co.uk/technology/news/7759347/Scientists-create-worlds-smallest-electronic-switch.html> You have to lo... 28 May 2010 06:05
DAS recommendation I am searching for a portable (low cost) data acquisition system with minimum 4 analog channels and 200 ksamples/sec. simultaneous sampling. I will be processing signals of a few hundreds of micro volts to hundreds of millivolts. I will be streaming the data to a pc for logging. Any recommendations ? I have ask... 25 May 2010 21:15
