This looks cool! How much and when will it be ready?
I'm still messing with the setup & changing my program, so I'd say about a month. Already added resizable/movable plates and poppers, now working on a swinger target.
The biggest issue I see is that some computer knowledge is required: a separate (free) program needs to be set up to register laser hits. It has to be adjusted so that only laser dot is registered, not the ambient light. Finally, it needs to be calibrated by using a regular laser pointer - mine is from a dollar store.

The system - like most of its kind - uses a webcam. I use PS3Eye, it is generally recommended for its high frame rate and ability to control its settings manually.
So far, I only figured out how to detect laser hits on a monitor. I'd like to have a working solution for projectors as well.
I haven't decided on the price yet - this will depend on how much more time/effort is required. I started messing with this last December, and really like the results so far. Once done, the program will be available for about $100. I assume most people have a webcam of some sort, if not, the PS3Eye is about $40.
The laser cartridge is only half of the system. There is a target that costs about 200.00 (and looks like a toy from 1980) that registers the hits so that you are not training to look for the hit.
There is a guy on Brian Enos' forum who makes a similar device for $40US +shipping. It makes a sound when target is hit, no LED rings like on the Laserlyte. The box is typically placed in the A-zone of a USPSA target. This guy can't keep up with his orders and has a waiting list.
Totally agree with you, anything to stop one from looking at the laser dot is good.
