Where do you get them made? Any chance to also make some for the Snark Barker? :)

Hi, just want you to tell that I'd love to support this project if I could.
Unfortunately, I can't at the moment since I'm very short on money right now.
If you still need some tests for comparsion against a SB2, SB16, PAS16 or ThunderBoard, please let me know.

Ok, this is how the assembled board looks like without a bracket:

Measured the noise - compared to a prototype's -94dB this has around -90dB, still good, but must be better. I use an output relay with a delayed (2 sec) switch to eliminate speakers pop on power up, its coil is powered from an unfiltered 5V rail, probably there is interference and I should fix it.
Now there is a led near the output jack which lights up when the relay clicks - really cool :cool:
The PB1 pin of the atmega is routed to H6 header now, it can be used for firmware debugging etc.
I wanted to use custom cables at first for PC SPK and CD IN, that is why these are 2 and 3-pin. But now I dropped it in favor of standard cables.
Putting voltage regulators between 2 rows of electrolityc caps was a bad idea too :dead:
After making final corrections I will order 20pcs in ENIG finish for the kits. Brackets are still in production.

The list is opened, if anyone else wants the kit - you are very welcome.

Happy holidays everyone!
