IDX-PRO+VDI

[blobber]

Very nice design!

How is your performance in air?
You have made two gaps in the graphite layer, right?

[Nandor]

Thats very nice man ! We hade the same idea even the foam grip is the same black with red! Is your stem made of 2 piece's can you separate them? Thats what I wanted to do but have no idea how to make it. I like the coil thats my favorite of the White's design. You helped me a lot thanks again!

Look's very cool dude.
This is my with arduino vdi, but with unfinished cosmetic's.

Hello Blobber, thank you ! I have mixed lacquer(for wood) with graphite and covered the housing 2x with it and glued a drain wire to the housing. I have seen this technique here on the forum. The resistance of the shielding was less than 1kOhm from one end to another. Than I placed the coils than the epoxy resin just to cover the coils than another layer of graphite and a final resin layer. You can paint the outrside of the housing with graphite to have a better shielding but you have to connect drainwires. Check this thread it's very informative on building a graphite shielded coil "http://www.geotech1.com/forums/showthread.php?21305-XP-deus-coil-modification&highlight=henrikas"

I remember, that some years ago for another project, I replaced a MPSA13 by only BC337 and it was working very well. Even until today, I never changed this transistor.

thanks Blobber
I try BC337 hfe looking for a good gain.

This is my idx.

Very nice done Nandor, could* you or someone else please explain more details about shilding the coil with graphite? I saw different designs with gaps and also without. Which homemade graphite mixtures are working well? Which resistance per centimeter is at least necessarry?

Hello Nandor,

Do you have pcb lay? nice and simple

Thank,
Wahyu.

Of course you will find the layout in the thread here, but here is the same version like Nándor's pcb. The first file is what I have made and also with VDI connection. Well like always, I changed the pad sizes. The detector is one of my favorite.

Hello
I explained bad, practically the BC517 is replaced by 2 transistors (BC547-BC337) mounted and connected in a darlington configuration.
hfe the gain is the sum of the 2 transistors.

[CDI]

Hello to all
I thought I'd replace the transistor BC517 (untraceable) with BC547-BC337 couple in Darlington configuration audio amp.
you think you can do?
I'm building IDXpro Silverdog pcb.
Thank you all

No,u can't.
Because mpsa13/bc517 is darlington type.

Hello Wahyu
I have the pcb from Silverdog from the UK http://www.silverdog.co.uk/shop2/ind...product_id=123

Thank you very much "gurdal''!
