TD3X ( pi )

[DOOLEY]

hello DBANNER,

on the original ( strip board version )
it's not a 16 pin ic you see,

it's 2 x 8 pin sockets / chips that happen to be placed together,
they are the TL062's for earth field and 1 volt ref source.

but does look like a single 16 pin when a wire passes directly over where the 2 chips meet.

[dbanner]

I see a 16 pin IC on Dooley's stripboard but I don't see it on the schematic. Am I missing something?

[liudengyuan]

Does anyone make it? Is it ZERO useful? Is it stable? Is the detection range better than the XR71?

I have one of the original PCB’s.
I would love to get an error free one
Please let us know when they become available

Can you shared pcb up-down pictures?

[nickel_n]

Yes the board had some issues (so this is an error).
If there's an interest I would build another batch, offering error free boards for those who already have this board.
However something must be done with the sound, it's very scratchy or at least mine was.
Probably It's best to revert that to Dooley's original sound.

Hmm unfortunately no, 1st and only batch of boards and contain few errors here and there
(this one noted here, few trimmers will need just 2 pins due to wrong connection of the 3rd pin, also check the 555 oscillator for proper pulse width/frequency, I remember I had to make on the fly changes to make it work proper).

hello eclipse....so the pcb i have is up to date and been corrected ????

[eclipse]

You've got it

[daverave]

i already have the original pcb...and want to know if there is a parts list ????

Yes those vactrols have relatively slow response so filter the sound nicely.

Parts list ???

[galaksi]

Boards have been sent. They should arrive in 3 weeks or so. I will prepare parts list soon.

Which is incorrect? Pcb or sch. IC6 6.pin GND connected.

The sound appears to be frequency dependant btw (PPS). Overheating was fixed with turning down the frequency, was too high when overheated.

That sound issue is curious, wonder why that is?
