[NJARC] Technoweenie Stocking Stuffer -- PDF File

Hi Gang,

I made a PDF file of information I found on Ebay, attached

Spelling is from China, I guess?

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
