Reading through the posts I understand you've spent considerable time and effort in getting the boards made.
Will there be any chance that you'd be letting go of any/reproducing any? I'm interested to get my hands on a unit.
Thanks!
]]>1. Can the AT91SAM7S512-AU be replaced by its successor, version B?
2. Can the OMRON Relay in RLY1 be replaced with Panasonic TQ2SA-5V?
Thanks in advance
]]>just for exercise i modified the board shematic, to see if i can do it cheaper.
You find it here: proxmark3.1.pdf
Here what i did:
-removed C8 (it was only 1nF and it's in parallel with a 4,7uF capacitor C9!!)
Hello gaucho. I'd be interested in collaborating on an alternative h/w version of the PM3 (if you're still planning it after your marathon build!).
I'm an electronics engineer by education and training but the time I have available to work on personal projects may be limited.
The link to your proposed alternative schematic is broken. Is there an alternative link?
Also - with regard to your proposal to remove C8 I'd advise against it. The two capacitors are in parallel and one may therefore seem to be redundant, but they perform slightly different tasks. The 4.7uF cap smooths the PSU but can't really decouple HF noise from the power line. That's done by the 1nF cap.
A quick explanation here: http://www.capacitorguide.com/coupling-and-decoupling/

Perfectly working
i've seen some posts with enhancements of the "old" proxmark3 eG Bluetooth options and lcd .
I'm not sure if theese posts where ideas or now implemented.
so: is there a newer hardware on the marked?
if yes, i am highly interested to buy a ready assembled one. this is the only way for me to support the community.
or wait, i can deliver some plots from unknown rfid tokens and cards. i have some devices which i am not able to recognize with the given types of the proxmark, but this is another story.
Thank you sooo much for all the effort you put into these proxmarks!
The list of issues you encountered and fixed(!) is quite impressive!
And of course: thx to all the community members how helped him!
oh well
]]>sent the parcels to Res,Benoit,ikarus and twixx
I miss only betelgeuse and new_user13 . I sent them private mail.
Coming back from the post office i was thinking that a PM3 with the bluetooth will be easyer to integrate with the smartphone.
But may be it saves nothing on client coding.
on the parcels i wrote "not working parts - to be repaired" just to avoid the customs (in some cases were not needed but i was in hurry and i wrote it on all the boards), so NO FEAR, boards are ok.
I will send to you private email with the tracking number of the shipment.
Please when you receive do these steps in order:
1)test it and check that it works.
2)post here your thanks
3)flash latest FW revision cause some board has a test firmware version.
i will write here detailed info for newbye about steps to follow.
NOTE: if you ordered also other items they are included in your parcel, so don't bother me if it is not needed.
