PICKINI - an easy to build PI detector

[N0QBH]

Thanks for the info, F117.
The plan here is to use a LiPo 14.4v battery pack and a 12v low drop out regulator at the pack to power the Pickini.
Now to choose a coil design.
What seems to be the best all around coil design and value for the Pickini circuit?

Nice looking PCB's
Be aware that these PCBs are for Pickini V3 which has a separate thread:
http://www.geotech1.com/forums/showt...ld-PI-detector

The main disadvantage of V3 over V1/2 described in this thread is that the performance of V3 is changing with changing power supply voltage. V1 and V2 have an onboard 12V regulator.

What seems to be the best all around coil design and value for the Pickini circuit?

A basic bundle coil 20 cm diameter, 25 turns of PVC insulated litze wire or enameled copper wire will do - around 350 microHenry.
Check out the coils forum + coil designs used for other PI projects like surfPI,..
Shield the coil all around except for a 1 cm gap. Connect the shield to ground.

I won't go into more detail here as there is plenty of information already on this forum on coils.

Best regards,
