Hi all.

(Mission Impossible voice)
"Your challenge should you choose to accept it, is before 12 midnight on Friday 14th September design build and test a circuit which is able to reliably detect a signal between 25 and 27 MHz and display an indication. The test circuit it must sense is an unshielded micro (3.3V) oscillator as used on many cheap Bluetooth dongles, Wi-Fi cards and other devices at a preset distance of 10.0 metres. The antenna, circuit and other parts must cost less than £10 UK or equivalent, ideally also be portable enough to fit into a sensible case."

Prize 1 for best working tested circuit: box containing Pi Zero W with NoIR camera and "other goodies".

Prize 2, for "most novel circuit" a slightly smaller box.

EDIT: Extended to whenever *any* circuit is submitted.
