      Thanks, great documentation :).
      Btw. what do u think about http://www.seeedstudio.com/depot/micro-digital-storage-oscilloscopedso-nano-p-512.html ? Is it worth buying ? (Not “instead” real scope, more like 3rd channel/take-anywhere scope)

      I had built a mA prototype a year ago, I must say, to overcome the above mentioned problems with available components (100mohm precision current shunt, quad JFET input Internally Compensated OpAmp wired as Instrumentation Amplifier with a voltage gain of 10.
      The uCurrent project being far superior demands components the market have not heard about. Just for being a little curious and as the article mentions ‘Blank PCB
