"OLD FORGOTTEN METAL DETECTOR'S"

[Qiaozhi]

Don't worry about components labels.
We can try to figure those out somehow.
What's more important is we to have accurate pcb traces.
Take a close shots (macros) of pcb, both sides.
Give here photos.
I will redraw it in more suitable format and give it back here.
Than you can write on it measured values of resistors etc..
Once we finish that, don't worry, i will figure out IC labels with no effort at all.
That's how we can reverse ee on it.
Winter is coming, lot of spare time.
We can make it, if you want!
Just make those close shots for now.
Cheers!

Depending on the model, you might have some trouble back-engineering the Red Heat.
I seem to remember reading somewhere that the latest model contains 4 microcontrollers.

....love his resistor turn-store.. ( how to call it ) nice invention !

seems a dispenser of resistors... it's a nice idea and speed up things when need to mount a pcb

Agree. In case of uPC we can do nothing.
I have no idea what's inside, that's why i suggested him to take close shots.
But even if it has uPC, still it would be interesting to see the rest of electronics.
XP Gold Max Power is also "protected" by having PIC inside.
Yet i learned some things analyzing it's analogue part.

This is cool way to hold a coil while testing!
I like it!
Will make the same!

Yes.... some nice things in the photo,s ...... say's more than 1000 words....

Thanks Vic....

REDHEAT

Thanks for all the interest and photos.
Not sure what model this is,I believe there were only a few models,so this has to be a very early one. Have included some board photos (top only) as you can see the board screws are glued..I have included a photo of the battery/phone socket/switch box (homemade) Has anyone any photos of how these were mounted? as the top of is missing.

Left Disc Right Boost. + on/off on battery box (2x9volt) below.



How's the box mounted?

Thanks for the photo,s....... think Ivica can dream the circuit... http://www.geotech1.com/forums/showt...=goldy&page=53 looks much like it, only the 'filtering' is from the silver+ just a guess ..?

Best regards.

No problem.
Very curious on how that batt box is mounted-Its made up from individual
pieces all glued together

Pffffff!?!?
You must be joking!?
That's the famous Red Heat!?!
No way!
You are joking here!?

The 9V batt. holders can be bought as a spare look for an indication

I know its a REDHEAT (See other posts) The REDHEAT stickers on the sides was a dead giveaway

Yes I know.They fit these to Viking Detectors.

So?
I will put stickers: "Nautilus Gold Max Power 18DX" on my next IGSL.
Will you pay it $1200 ?

[chopz54]

So your not familiar/interested with any early models?

Of course i am (interested) !
Thank You Very Much for posting it!
It is informative indeed!
I must admit that i didn't knew there are more RH models!?
I thought it was only one of a kind.
My mistake.
Cheers!
