Lasers / Re: I just ordered a new green laser!

They are diode drivers. (analog modulation) 1.5A

2-Red (PBS)
1-Green
1-Blue - 445nm
1-Violet - 405nm

Next I am working on a PSU and microprocessor controlled "Gain" to give me full control of each laser min-max power output using a atmega328 and digital pots.
I know I can adjust this in software but in stand alone mode a hardware approach is the best solution.
Plus I can lock all RGB channels to keep the optimum white balance at lower outputs.

Using a microprocessor also allows me to log temp and output (mA) and some error and fault control.

The current drivers I made are designed to adapt to the mods easily.

DACs / TTL LB-Dac Test

« on: July 04, 2010, 04:35:28 pm »

I have been looking at the output from the LB-Dac on my Oscope.

What I have done is make a simple WAV output for the TTL, Then look at it on my Oscope.
Is what I am seeing normal output for the LB-Dac?


First pic - Oscope output
Sec Pic - How I made the TTL

Yes James we do drink Budweiser here too. lol

Thanks for spending some time with me and llaw to teach use how to use Laserboy.


Am now starting the next stage of my projector build.
Just done my first LPC815 and GGW harvest and press.

Here are some Pix of my LaserBoy Correction Amp.
I used a 8 Channel CM106 USB Sound Card.

woow. Extremal detailed reply. 

If I need extra wide X and Y, As you say I can change input sensitivity on the scanner amps.
I don't want to over draw current from the USB.
What DC/DC converter do you use / recommend?

Thanks so much. you have cleared alot up for me.

Thanks James for your fast reply.


So would this DC/DC converter work ok?

Hello all at LaserBoy Forum.

I have been looking to make a sound card Dac for some time now.
I am having problems understanding the schematic input connections.

Thanks alot.
