Hi,
I haven't been on here in quite some time and haven't messed with lasers for a while either.
In the past I have built a couple of laser projectors, they were a 300mw 532nm green with 40kpps scanners from eBay, I think they were laserworld branded. I also built a 500mw 532nm green with the same scanners. I ran these with Medialas Mamba Black 1.90. I've since sold these lasers and software, the guy I sold the software to is a friend so he lets me borrow it back now and again :-)
I've acquired, really cheaply an Equinox Vixen RGB laser, which for a cheap laser is ok, but at a guess I'd say the scanners are at best 20kpps??? anyone know exactly what they are?. The convergance of the RGB lasers is off and on taking the thing apart it's no wonder because the engineering for the mountings etc.... is shocking! It's obviously a very cheaply made Chinese effort. As a project I think I'm going to make new more robust mountings etc.... I trained as a mechanical engineer originally so have the skills to mill new parts. I may put faster galvos in this too.
I would really like to have a good RGB projector (maybe 1-2W) with reasonably fast scanners and preferably analog modulation so I have a larger range of colours available to me.
Like I say, I've been out of this for a bit so I'm not well up on what's available these days.
So a few questions for those of you in the know.
1. Do I Build my own or buy a prebuilt Laserworld or other....?
2. I notice that Laserworld quote their scan speeds at say 40kpps, but this is at 4 degrees...... is that going to be good enough for graphics? are the 40kpps Galvos on ebay faster than these?
3. If I did build my own where are the best places to buy components? Laser modules, Galvo's, optics etc.....
4. What show software would you recommend? I still quite like Mamba Black 1.90, but I'm guessing things have moved on since then?
5. What proportions (powerwise) of Red, Green and Blue lasers should I use?
Hope some of you can give me a few tips with all this.
Thanks in advance
