can I use PS section only as a low noise voltage reg 5 Vdc to 35 Vdc
what are your practical results
current range

Salas · 9th July 2009, 06:47 PM

No. Because you will need space for substantial sinks. The orientation of the Mosfets isn't for heatsinks.

Look at the proper pcb

Also read that thread from start.

there might be a way to mount heatsink
how much ma B1 consumes

Salas · 9th July 2009, 07:09 PM

Plus and minus 17mA and the shunts are set at 60mA each. One bank has backs to the outside, but the front row to the inside. Its a hassle, plus it is fixed Vref with leds.

Ryssen · 9th July 2009, 07:36 PM

I am going to give it a try at 13-15v,a led or two more.
With a load of 40mA.

Salas · 9th July 2009, 07:58 PM

OK. Crt replied that anybody who can and like, can ask for the eagle file and try to match the pdf for Gerber.

Edit:If I order 80pcb´s from pcbcart the unit price is $ 1.71 + shipping and stuff,will calculate tomorrow.(allmost to god to be true.

Dang, that is a good price. If they turn out well I will try them for the second batch of Diamante boards.

I calulated the price with toolingcost, shipping and taxes to me,and it ads up to 4,12$/pcb

This is what the price is when all fees (toolingcost) and stuff are addd:4,12$
And the price might vary some depending on the exchanges coarse.

Salas,arent you skilled to fix the Eagle files?
