Further developed and worked with during the Lab-in-the-Wild @ PIFcamp, Trenta 2015

Intro

It's basically the same circuit as the NanoSmano Sajica aka Vive-la-Resistance, as documented on the SGMK wiki. A basic 4093 single oscillator using 1 NAND gate with a very small capacitor (1 - 10 nF), leaving the pads for the resistor open to play with. Then buffering the output through another gate to control the LED and further buffering it through a gate to be used as output for a piezo or read-out using the freqCount library.

The History

Orignally made during the NanoSmano Small Matter, May 2011 in Ljubljana, to use as a model of a NanoCarbon based gas sensor.

See the other workshops from Du du kuglica sajica mavrica

Very simple making of a PCB using photolitho and using a resistive "surface" as a sensing area, coating it with different materials such as soot (black carbon). The use as a "Salami-Sensor" has been questioned though...
