For full speed DVD an 18k is enough to handle vertical positioning. Horizontal would require a high-speed spinning mirror. That's far out of range for any galvos.

The controller, galvos, and blanking device. Sorry.

30k scanners, 11MHz blanking, and a controller capable of accepting and processing data at a rate of over 170MHz for full DVD resolution raster with 16-bit color and full framerate. That's my goal.

You don't. You mount the laser and select a target such as in a lab, and focus to that. Shooting across the street is high risk, and may be illegal depending on where you are.

As soon as I can figure out a good, relatively cheap solution to raster scanning (likely in a few years :P ) I'll post a how-to on building a raster laser display head. For now, all I can do is warn you that this one won't be easy. It's sure to require high precision and will be high difficulty.

It's probably Hotmail that's messing things up. My accounts randomly stop accepting mail, start dropping mail for no reason and with no warnings, or time out in trying to retrieve mail. MS has their head up their arse on that service.

Re: Starting tonight, 13 Sept - new GB for 16xdiod I'm almost tempted to buy two more, but I don't want to Bogart the lasers. ;D That, and I wouldn't be able to buy the fuel to get to the parts store for additional driver boards.

Feces occurs. We can't blame you for them being lazy. :P

That reminds me of the light show made from two broken computer hard drives and a laser.

I hadn't thought of doing it that way. A positioning rate of 6k to 15k on a good galvo isn't too much to ask. Handling the blanking at the full speed would still be an issue, however. You'd still have the full 2MHz or 250MHz. It would probably require use of laser modulation to properly account...

Sorry, I have to pop the dream balloon here. ;) Having looked into the requirements for developing a laser-driven raster display, I'll post the skinny of my discovery here: The downside is handling the servos, the servo driver, and the data processing for something like that. It may be...

Re: red and green wl lasershades interest gauge Depending on funds at the time, I'd be up for a red and green. That'll leave me with needing only to track down a set for IR.

Easy trick. Use a digital camera/camcorder/picture cell phone and take a picture of the diode's target. My solution to verifying infrared LDs was to set the diode to be tested without any lens approximately 6 inches from a piece of paper. Use the camera's screen (not viewfinder) to look at the...

No harm in trying. Worst it could do is result in SPAM and/or mailed lit on lasers.

Re: Starting tonight, 13 Sept - new GB for 16xdiod It's not so much a matter of procrastination as a matter of $$. You can only buy things when you have $$, and I had to steal some back from the moths to buy in on these. As far as the housings, I snagged one of the blank packs Aixiz put up...

Sounds about what I figured. I'm glad I just snapped up 2 from your GB order.

Re: Starting tonight, 13 Sept - new GB for 16xdiod Yay. Two just paid by me. That leaves me with one more housing to fill out of the order I placed for them, too. :)

Aixiz is currently advertising a 200mw red diode for $40US on their main page. Anyone tested this one yet, or have any feedback on it? From the main page for Aixiz, scroll down to the diode listed for the Kip Kay project (second one listed)

Last day indeed, and what the heck. +1 for me on that list. How often do you get a chance to play with violet lasers, after all? :D

After a night of no sleep, I decided to post the resulting schematic from an attempt to trace out the Aixiz driver. This probably will not work for most other lasers without modification, so I'm posting it only for information and discussion ...
