ELEKTR0 SM0K - Handheld spatial EMF scanner [green prototype]

from GRM / TOTES FORMAT

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 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 MDF wood.
Size: 10cm X 4.8cm.
Handmade by GRM for METSÄÄN. metsn.tumblr.com

Full Device: 55€

Just the PCB: 15€
