[NJARC] Technoweenie Stocking Stuffer

[antqradio at sbcglobal.net]

I had bought an earlier generation of an LCR meter about 2.5 years ago for $23.00.  Worked fine for a year then it quit.  To be fair, the micro-controller was not in a package but was wire bonded to the circuit board and then epoxied in place.  So it will be interesting to see how reliable this generation will turn out to be.  Anyone else have this problem?Jim

  Gang,
 
 I just took delivery of this component tester.
 
 
 You don't even have to know what component.  Just stick something in the zero-insertion-force socket, push the button, and the tin brain inside figures it out.  Does resistors, capacitors, inductors, diodes, and bipolar and FET transistors.
 
 The best part:  It's 15 bucks shipped from Duluth, GA. -

 There are a bunch of these floating around on E-bay, but this appears to be the latest revision, with a really nice display and rugged battery holder.  You'll likely want to install in in some sort of box to carry around.
 
 All this is made possible by a modern microcontroller that has analog inputs and outputs built in, so it can make the appropriate measurements.
 uC data sheet here:  ATmega48A, ATmega48PA, ATmega88A, ATmega88PA, ATmega168A, ATmega1688PA, ATmega328, ATmega328P datasheet -atmel-8271-8-bit-avr-microcontroller-atmega48a-48pa-88a-88pa-168a-168pa-328-328p_datasheet_complete.pdf
 
 Not much on the circuit board except the processor and an 8MHz crystal.  Everything else in SMOP. (Simply a Matter Of Programming)  Welcome to the 21st Century!
 
 Thanks to Robert Forte for making me aware of these things, and Joe Cro for kicking my butt to actually get one.
 
 My apologies for the freak out,
 Al
