NO ERRORS!!

Re: tiny

did you buy anything ready made from pulsedetector?

Re: tiny

NO!!I get the parts from diferent suppliers.

Re: tiny

I built the tiny project also.Which coil you have made.Diameter of the coil,wire?I get the best result when the power supply = 9v.More then 9v it works bat.with a 25 mm copper coin the max depth is 17 cm in air.What results have you?

Re: tiny

The coil diameter I made is 190mm .71mm wire.
With a coin of 23mm Nikel.I get 22 cm in air

Hi Sergio

How many windings has your coil? Is it a single coil or? I made my own PCB of the TINY. But have not assembled a proper search coil jet. So far what I tested I can say that the unit is working fine with a test coil.

Hi Sergio

I don't know whether you saw it. In the TINY schematic is a little error. The pin 9 of U3 must be connected to ground as well! The PCB is okay!
And in the component list is a small typing error. The first R3 should be R23=10K ohms.

Re: tiny

Hello Cris! The PCB is OK pin 9 of U3 is conected to GND.But in the squematic pin 9 is missing.
I dont see any problem in performance about R3.I have it with 1K.But I think is 10K I think 10K is the correct one.
Im going to swap! the resistors and see the diference.

Re: tiny

10K is the correct one. I ask the designer Pulsi.
