Etching a LD driver PCB

Hello all,
I'm going to etch a driver board on my CnC today. I was wondering if anyone has
a layout in a dxf or eps format. I can make one up but if one was already available.
I'll use Daedal's circuit, if it turns out maybe I'm willing to distribute these out to those who might want some. If anybody would like to help out on this venture it would greatly be appreciated.
I have not done this on my cnc before but i have milled some pretty small stuff. And I do have the right tooling. So it should be possible.
I was thinking of a design that would make it simple for any DIY'er to solder so thru hole seems to be the most simple.
I'm not sure what style VR would be the best to keep it small, but Radio Shack component's would be the easiest to obtain.
I'm also not sure about the boards size, I would like to shoot for 12mm wide by 25 mm long.
I don't have the dims on all the component's yet so I'm not sure if thats possible.
I welcome any commits or suggestions, is it something anybody might be interested in?
I know I'm a noobe here but I would like to be able to contribute in some way.

Thanks for reading
Chuck

I'm jealous of the CnC but for something with just a couple of parts, it seemed to me that point-to-point wiring on some perfboard was good enough.
But then I always put the capacitor and diode inside the Aixiz module.

I'd suggest not putting the capacitor on the board - too much risk of charging it up with no LD connected or a bad connection.

I'd also lobby for a 1 Ohm resistor just before the output to the diode, with a test-point on either side, for convenient measurement of the output current.

I kinda hate to use a 1-turn RS pot rather than a 25 or 10-turn, but yeah, they are available almost everywhere. (Do they go as low as 100 Ohms in the stores?)

Thanks for the input, much appreciated.
i guess your right on the not needed, doesn't appear to be much interest in it.
i think I'll give it a whirl just to see if I can do it.
i agree the 1 ohm would be a nice addition, I have drew up the cad drawing so all i have to do is mount the job and try it out. if i can squeeze in the test points I will...things kinda got tight.

here's a simple point to point that i used for reference.

Putting the capacitor across the laser diode is the best place for it.
BUT, as long as you have good connections, and use a 1 ohm resistor to measure current as Zarniwoop suggested, you will be ok. For parts check here

I think he has everything except the 317. I got some capacitors and 50ohm precision trim pots from him and the trim pots are really nice. He also has 1 ohm 2 watt resistors...I believe the recommended minimum is 1 watt but his prices are good and he will combine shipping.

Thanks Gazoo, I'll check it out.
I will remove the cap and use the space for a resistor.

Here's the second version.
I removed the cap so it can be soldered directly to the LD.
I added a mount for a 1 watt resistor in series with the positive output.
Included holes so loop test points could be added to measure the current.
Changed the footprint on the pot to a 10 turn Spectrol trimpot.
Suggestions? Commits?....All are appreciated and welcome.

Here's the first version cut.
The componet's used were what i had handy..just checking the fit.
I might make the profile a tad larger on the next one.

Looks nice, and small
