GOLDSCAN 5 SCHEMATIC QUESTION

[dbanner]

this is my proposed layout for main board. VCO audio and power supply will be on seperate boards. All components have been labelled. Some mistakes have been corrected.

[Toros]

With what TL052 is better than TL062 ?

Goldscan 4 for sale with deffect (“It all works but has gained a small problem it detunes itself”) in good condition for 250GBP.
Old, used and broken it goes for high bucks, it's just like when you buy Lamborghini or Ferrari and you sell it it after XX years it still fetches good bucks.

Anyone made progress on the 5th GS ?
I'm still stuck on the PIC32 software, decided I want audio controlled by the MCU, instead of using descrete components, so it takes lots of time.

ive not done any projects for several months cause of my depression problems......so GS 5 on hold for now...i did manage to do some detecting on beach and found a palladium wedding band ring...but ive now returned it to its owner...i read on another site fisher are teaming up with the french guy who developed the manta detector and doing a discriminating iron pulse machine...bet it will be very expensive.

Hey Dave
here in Australia they are having good success with Neurofolin which contains L-methylfolate, an active form of folate that addresses part of a complex deficiency found in people with depression
its a simple over the counter supplement that can be purchased without prescription under various brand names in pharmacies.

Hi 6666.....many thanks for your advice concerning depression...its something ive had for a long time but got worst cause of different things that have happened to me in the past
it just interfears at times with me being able to do things like my electronic projects.....to be honest i do not trust the pharma companies anymore
cause of all this forced vaccination business which is a big problem i believe in australia...america..and now parts of europe...people should be able
to choose for themselves...so i mistrust pharma now and prefer to go the natural way.

[dbanner]

Seems no interest anymore. anyway, here is good layout i did some time back.

Thanks Dbanner, did you build it to prove it works ?, and do you have the timings ?

[dbanner]

yes i have the timing data somewhere, and no i haven't had the time to build and verify. It's something i would like to do but most people seem to be stuck on surf and baracuda in perpetuity.

[dbanner]

parts labelled to correspond with my layout

[dbanner]

i started working on the audio section from original, but this is as far as i got. without better photos its impossible to complete. actually the audio section can be adapted as there are many solutions out there. The power supply is straightforward and easy.

[6666]

You have spent a lot of time on this thanks.

[Orbit]

Audio section very critical .
