A little upgrade to my CMoy. Made a new PCB to accommodate a low voltage indicator circuit (LED turns red when battery drops below 7,2 volts) and a trickle charger. As I had used up all the space on the end panels, the first time I built it, I now had to mount the charger socket vertically. It's a Hammond 1455C801 enclosure.

@ Reintz
Good job on the that hand drawn?
I've been using that voltage trigger in my builds too, works great
doesn't it...

So it took me longer than I expected, but I finally finished off my AMB alpha 10. Here are some pics:



And here it is in action:

alpha 10 is the top box, beta 22 is in the middle, and the sigma 22 for the beta 22 as well as the trafos/ssr for the alpha 10 are in the bottom box. 
A big thanks to Ti for making all of these awesome projects so well documented and accessible!
Just for kicks here is my complete AMB signal chain - PC --> gamma 2 --> alpha 10 --> beta 22

Wow, very impressive! Great looking too!

bcg27:  This makes me wish I had the time, space and money to build something like that!  Beautiful build dude.  :D

Thanks for the compliments!
@Pageygeeza: I built these on and off over a period of about 6 months as I had some spare time. I also did all of my soldering, construction, and testing on my 4 foot diameter dining table. Any drilling or dremeling was done on my balcony which is maybe 8x10. So you don't really need a lot of space to do stuff like this, and since it is for yourself you can take as long as you want to build it.

How do you get ExpressPCB to print out?
I didn't think it would print layouts...

Thanks, I used ExpressPCB as always. And I'm rather pleased with that voltage trigger - great little thingy.

Thats good information for anyone looking for a good/free layout program.
I'll try and remember to pass that on to people. I use Eagle myself now,
but I have used ExpressPCB  quite a bit when I was getting boards done at work.
I use pdf995 Just install it and when you print in ExpressPCB then choose "PDF995" as your printer. Instead of printing, it creates a .pdf file of the layout. Then just print that .pdf file.

I was wondering if anyone had any extra heatshrink that they could send me? I would need about an inch or two of two different colors (preferably red and white) to identify the left and right side of a my headphones? PM me if you are able to help.
