ELECTR0 SM0K - HANDHELD SPATIAL EMF SCANNER
[green prototype]
A spatial handheld EMF scanner, that translates electro magentic fields into stereo audio (noise) signals. This device is based on the 'Electrosluch3+' circuit by Jonáš Gruska. A VOLUME pot controls the output via 3.5mm stereo socket for headphones or direct connection of a recorder (most recorders are EMF sources themselves!). The circuit incorporates a high performance OPA2134 amplifier IC for best sound quality. An UV or bright green LED indicates the ON/OFF state (toggleswitch) of the device and illuminates the 'scanned' zones. A 3.5mm stereo input socket in the front to connect your own coils (eg. 10mH) for experimental set-ups (if you plug something in, the coild on the PCB will be disabled.) The device runs on 9V DC provided by a battery (DURACELL INDUSTRIAL included), sandwiched between two layers of PCB. The solder points are isolated by a bottom plate made from recycled transparent acryl or MDF wood plate (please, indicate what you prefer.) Size: 10cm X 4.8cm. Handmade by GRM for METSÄÄN.
Full Device: Sold.
Just the PCB: 15€
Here's the first demo video, that i've made:

A better one shall follow. Maybe i even manage to get out in the field, have to go to the city for that, i am lucky that here in the forest, is not much going on.
