Hi, Alex. great job. Did you use FTIR? or LLP? also I made one with LLP way. however, it seems a bit problem with recongnization. :)

Super! here is the question. when I use LLP way. I found a problem some finger point cannot recognize. coz, other fingers can be blocked laser often. how did you set up for this problem. I think when you set up you might have got the same problem. :)

and also if you use acrylics. it might bend that makes laser cannot spread widely. (sorry for poor english. kkk)

you can watch my one as well. :)

I think you can see the problem when I use tbeta calibration.

I see. In your case, you put 4 lasers at the end of corners, am I right? actually I put 2 lasers. :)

ans also I bought second-hand lasers. coz, I couldn't find good and right lasers in korea. if you don't mind could you tell me links to buy right lasers from online shopping mall? or if you don't mind could you tell me all you use equiptments list and where you bought? ^^

and how did you fix position for Laser?

thx your help. :)

Thanks a lot. :)
