$45 basic kit now avalible
This metal detector is built to be as simple as possible yet retain all the sensitivity of a more advanced model.
Built around the ATTiny 25/45/85 Series Microcontroller, It compresses what would be hundereds of analog componets into two of these chips
With under 16 componets it can be built in an afternoon.
The unit is also highly customizable and can drive small to large coils providing exellent sensitivity.
Powered by a 32 bit 400Mhz 8 threaded XMos XS1-L1 DSP and backed by a 2Msps Ultra low noise 16 bit ADC, this unit is designed from the ground up to compete with the highest-end Metal Detectors.
