I finally managed to get a proper solution for fixing the lasers... I used a method I've seen on nuigroup.com, from AdrianH, which is very clever and also simple. As he says, "Basically, it is a piece of metal resting on 4 screw-nuts, so that it is possible to adjust height/roll easily and precisely" I couldn't explain it myself better :).
I'll try to calibrate and make some resistance tests later, but the result feels pretty strong right now.
Hi there,
ReplyDeleteYour project is quite exactly what I have I mind for making my own MediaCenter/Cofee Table/Multitouch Device !
Great, I'll might bother you with some questions :)
Here is the first one: Is the limited vertical view angle of LCD a problem when you are sitting on your couch ?
As the view angle from the top is often better than from the bottom, may be you inverted the screen upside-down ?
And congrats !

Hello Thomas,
ReplyDeleteÇa me fait plaisir de voir que ce projet intéresse d'autres gens que moi ! :D
N'hésite pas à poser des questions, si je peux y répondre, je le ferai avec plaisir.
Concernant l'angle de vision, l'écran que j'ai utilisé est très bon : on voit très bien l'image, quelque soit l'angle.
J'ai effectivement néanmoins interverti l'image (simple rotation à 180° dans les paramètres d'affichage) et installé le LCD à l'envers pour maximiser la qualité mais j'avoue que ce n'était pas spécialement nécessaire.
A ta dispo !
Hi, What laser did you use? I bought 4 x 780nm 25mw lasers but the blobs are too weak. what do you recommend? should I buy 60 mw 780nm laser? or 80mw? (is only +3 dolars) I hope to hearing from you soon, thanks!
ReplyDeleteHi there ! Sorry I was on holiday and couldn't reply to you :)
ReplyDeleteI use 4 x 780nm 25mw lasers like you and I also have some trouble with the blob detection, especially in daylight, they're not quite steady :/
I don't have time at the moment to test, but switching to 60mW seems a good idea. If you change for them, could you keep me posted if the blob are better?
Cheers and keep up the hard work !
