Adam Amp !!!

[James Lehman]

Check this out!

300EVIL made this and gave me one at SELEM.







After all this time, I finally got a round tuit.

This is a really NEAT design. He used a full size USB jack, that is much stronger than the mini. Cool idea!

This board is based on the original LaserBoy Correction Amp schemo that Dean Hammonds drew back in 2004. It uses a 5.1 V zener diode as an offset voltage reference.

My review of this device is simple. It works perfectly!

What's the little pcb standing up straight for?

[Banthai]

im guessing thats a DC/DC converter that generates the +12v and -12v supplies (required for the opamps) from the 5v usb supply

all the best ... Karl

[FourDee]

Ah yes, that will be it

Hey James!
Thanks for the feedback! Glad to hear you like the board. Also, the 6th channel is pin selectable for the ILDA output. You can also use the voltage output of the DC-DC converter or the USB for signals sent to the ILDA connection. For instance, I used the 5V out for controlling my shutter to pin 13.
Thanks Again!
Adam

No problem.

You know I think the world of you.

I like your amp too!

It's the one I use now.

Nice tidy little amp there! Looks rather pro!

[James Lehman]

dave, do you use a sound card DAC ?

............ what about LaserBoy ?

James.

[300EVIL]

No problem.

I'm flattered dude! Thanks!

WOW! Thanks Dave! Sure was fun to build. I owe all the credit of the circuit design to Dean Hammonds though. I'm no circuit designer, I'm just good at layout.
