sounds like your the man

Holyuser, you are obviously sady uninformed. I've reverse engineered everything from microsoft basics, to a russian instrument. A good disassembler, and a debugger, and it will be a no brainer. So I am sure that ivconic will have no problem. Hell, I might even take a shot at it for fun, even though I don't know pic code. The russians said that an object file would do no good for helping reverse the instrument, but they were dead wrong. inside of 2 days I had a fully disassembled and semi commented file, in in 3 weeks I had a fully commented file and understood what they were doing with BOTH micros.

So the coil could bend with Poly ?
- not so good,
understand.

Yes not quite as good but the difference is only marginal except for the heat. Both make workable coils.

Are you talking about Polyurethane or Epoxy ?
I did not know that Polyurethane heats up.

The chemical reaction that hardens Polyurethane causes quite a bit of heat. A cup full of Polyurethane would be almost too hot to touch. I found that Polyurethane not a solid as cured epoxy but epoxy does take several days to harden properly.

I did a poly one, I wrapped glass strips around my coil - so I didnt have a potted void. So wasnt much curing volume, so didnt get hot.

Large volumes of poly almost smoke during cure and tend to shrink and crack. Small amounts is easier

Has anybody tried mounting a Coil into POLYURETHANE - instead of EPOXY ??
- It seems like a lot Cheaper !!

Yes done both polyurethane and epoxy. Well not be using polyurethane again.

Works usable but not as good.

Gets quite warm so null shifts.

Not as stable.

No I don't. I work for a medical device manufacturer and our products are based on 8051's from Sialbs. I've never used the Arduino, but I think the atmel mega is a good processor. I am not impressed with their 8051's because they don't have an embedded jtag debug block like the Silabs processors do. It makes debugging a lot easier. I've been an embedded programmer for over 25 years now.
A second unrelated question, is where does one find the IDX-PRO manual. All I can find on whites site is the classic ID/IDX which has different features from the IDX-PRO

This is good to know. You have been out of stock for ages. Any idea of the price in us dollars? I don't do pounds.....
I wish someone would take the 6000di series 3 schematic, and lay out a board for it. And for what it is worth, I'm an embedded systems programmer, with a lot of experience on the 8051 family, some on the pic24, and a lot on a whole batch of other fine processors (68000, 6800,6809,8080,z80,8031,6502, 6811 etc.) No pic 18 though. Consider most of the pics to be junk. Anyone with a 6 bit byte and a 17 bit address is an idiot.

You don't use Arduino ?

just for info - I have more IDX pro boards arriving within a week

I built one of Silverdogs IDX boards and now would not manufacturer my own IDX PCB. Makes a more reliable MD for use in the field with proper thru plating and varnished tracks. Saves all that drilling. Make debugging much easier if you know the PCB is correct to start with.

Does anyone have the gerbers for the idx pro board? i.e. a 1:1 full sized drawing file (or even a pdf) that can be used to print out the silk screen and the pcb traces? I've prowled through pages 92 to 111 of this forum and haven't found one. With Gerbers it would be easy to get these boards made, and with a 1:1 printable image, a laser transfer would work.
It does seem to me that the phase discrimination could be done with a microprocessor as long as the signals were conditioned into square wave. A phase detector is pretty strightforward with a good timing unit on a decent micro.
