Holy shit. That’s all I can say, simply…holy shit.
He goes into good detail about how he did this; could this be replicated pretty easily? I’ve already got some violet lasers on their way from china, and I know of a good galvometer setup (hard drives have galvometers in them already and there have been quite a few laser projectors made from them in the past). The whole resin floating on saltwater bit is very interesting as well.
Wow, that is freakishly clever. Using the sound card on the laptop, that is resourceful! Pretty sure I’m pledging on this one, just for curiousity’s sake… but I need to buy aluminum extrusion, decisions!
This is really cool, I have used the sound card for many things, they are really cheap and nice dacs. I had a friend who used it to control an rc plane (auto pilot), I am almost sad I didn’t think of this… but I have to say way to go.
@Qitian_Dasheng_Sun_W , read the FAQ on his site. He has plans on working around AC coupled output in order to turn it into DC coupled output. Some sound cards are AC, some are DC…
I still skipped over this although it was tempting. The guy seems more interested in design than a KS presentation which is good and some of the ideas are good, but not unique or novel. A lot of this stuff is available in the DIY laser show groups. Looking at the vids I think this design will appeal largely to people who like to spend endless hours ‘tuning’ something. At any rate, I wish him luck, while I don’t think it’s more innovative, I definitely feel that it’s a good push for the troubleshoot+resolve crowd. This design in the ‘real world’ would use pricey quality galvos and a reasonably high end drive system, his claim is that you can achieve this with some rubber band type items and scrap mirrors, good luck if he can… and you as an investor can. I don’t deny that it’s possible, but I think it’s a very very tunable system
