CRYFTON .....

[Geo]

Hi.
Some friends sent me schematics from Cryfton OBMD.
Schematics are not so clear so i will draw them with eagle and after it will attach here.
Because i have n't many free time it is more easy for me to give at the end a part list.
For the time the basic is to see the members what is happening with this lrl who cost so much money and is a mix of schematics from Andy Flind, Alonso's PD etc.
If i know will give info but will not criticize it.
I have n't so hight knowledge level.
I suppose that the schematic that i am working on is the OBMD-2 because the other one that i have is a little simpler...
If anyone has any comments, can write here...


Regards

btw... is there any problem from admins????

Bravo Geo. You are most friendly man in our galaxy.


Regarding those Cryfton, it is big question why constructor need to go
complicated (or compilated) way, when we know, that it is more than
enough to attach simple calculator to kids pistol and make big business.

It's ok as long as you don't post the manufacturer's original schematic.
Back-engineered schematics are allowed.

Here is the schematic of Cryfton. I don't know if it is obmd1 or obmd2.
If anybody knows can inform here.

Thank you Geo !
How to know the exact position of VR1 without the bargraph, unless there is a fixed value in the OBMD version ???

Part list next week. My opinion is that the IR iss doing NOTHING so you can find the value from other parts at Andy Flind thread.

thank you mr.Geo

[Geo]

Also i have another schematic (maybe the first) where there are some differences at IR section, all the rest are the same (preamplifier + Andy's MFD).
I will redraw it later.....


Also i have and newer schematics......

Longrangelocator's members love me and they give me any new schematic

[dragomir]

Geo, this is the scheme of OBMD - 1

[Geo]

Thanks Dragomir.
So i have two versions of OBMD-1 and it miss me the OBMD-2.
Maybe a good friend to send it to me....

Do you see any circular coil or OO coils with critical null????
THere is only one square coil....

I don't know, not critical.
You wrap 30 turns and play with the capacitor
