I am also very interested in the project and would like to have a schematic to implement.
I'd love to contribute to the project. Smile

Regards.

Has anyone attempted to do this project recently? I am very interested in trying, but could use some pointers.
Specifically, a more complete schematic would be very helpful, as well as any pointers in terms of programming and giving a output signal would be greatly appreciated.

hello, i would like to receive a copy of the full schematics too.

Thank you.

Yes, the topic is still live.

Have been burried in a lot of work the last months and didn't have the time to post any test results or schematics of this project. Time flies if you're having fun. Smile

It will take a few extra weeks before I will be able to post new information around the pulse induction metal detector. Please hold-on.

Hi, I am in a race to build a PI machine with depth capabilities of up to 8ft. The coil needs to be about 2m . Schematics would be really useful to me too as I may decide to try the build myself once i have a component list. Great website!! Hoarder

HELLO I AM ALSO INTERESTED IN THE PLANS FOR A PI
DETECTOR. AM LOOKING TO BUILD AN ALMOST ALL PLASTIC
ROBOT WITH 8+ COILS UNDER A 2 X 4 FOOT PLATFORM. THE
PARALLAX PROPELLER HAS MY INTEREST AS IT HAS 8 COGS OR CPU'S MORE LATER

Anyone know if the schematic for this project got posted? Would be interested in receiving them. Thanks.

I am also interested in building a pulse induction metal detector. My targets will be from 5' to 10' deep. Any help you can provide would be appreciated.

Sorry that I haven't updated anything about the project yet. Development is taking more time than expected and other activities are taking much of my precious time.

I am attempting to build this based on the system described on the main page. I do have a few questions though.

How was the value of 2k2 for R1 arrived at? With it in parallel with R2 would that not affect the "ideal damping" of 680 Ohms.

How critical is the 400V breakdown voltage of the MOSFET? That is for stage one but we are only measuring stage 3. I only ask because I have only found a MOSFET with a 55V BV. Based on calculations given, it will take 14us to leave stage 1 which is almost as long as stage 1, 2, & 3 together shown on the decay graph. I will continue to look around for the 400V BV component.
