suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
Here's the spinning mirror laser projector:

It's interesting, to say the least.

You can also build a very capable DAC using an 8 channel USB sound device and a correction amp kit.
LaserBoy is free and it can be used to make frames of text and numbers. Once you have what you want it takes a fraction of a second to generate a wave file that, when played on the USB sound card, produces the signals that control the laser projector.
It's not exactly real-time but with some practice, it's close.

LaserBoy and the modified USB sound device also work with a Raspberry Pi!
This is about as inexpensive and DYI as it gets!

All software has a learning curve usually proportional to its capabilities and unique features. Pointing with a mouse is in no way easier than tapping a key.
His latest out-of-the-box idea is to get 28 laser pointers with a grating on the end to project a short line.
Then arrange them in 4 sets of 7-segment numbers (like old LED displays). Then just selectively turn on and off each segment to display two scores.
I already told him that alignment is going to be hard, and of course, it would only work at one fixed distance, and if the distance changed, so would the alignment of each segment.
But this he can do for less than $100!
In addition, finding the right gratings might be a challenge. That said, this approach could be done within the $100 budget!
"Help, help, I'm being repressed!"
If over 5mw, I assume this is for some sort of public thing, being a scoreboard. How is this device for under $100 going to be compliant or is it in use where it isn't public and nothing is sold in the same venue?
Pretty awesome solution though!
