    Default SOLD: Dragon Tiger DT-30 Pros 30kpps Galvos (Used)

    I have a set of DT-30 Pro galvos with 3mm mirrors for sale that come from a recently upgraded projector. They have low hours on them and are functioning well with no signs of bearing grind or anything like that. They have very low hours on them.

    I am asking $130 plus shipping for them. If you are interested, please PM me with your location (US only please).

    Are these still available? I'd be interested.

    FYI, OPTlaser sells DT-40 galvo sets for ~$240 + shipping. They work great for my home system.
    Tried cheaper no-name ones from aliexpress, but they're not tuned and there's no documentation. Same deal with el cheapo RGB diode modules, BTW. RGB wouldn't stay aligned. But, they will work fine for lumia projectors. OPTlaser's W3000(w/o A)-RGB modules are far better.
    If you're planning to build your own projector, all things considered, it costs the same as OPTlaser's PD3000-RGB projector, which uses these same components. So, why not just purchase a fully functional ILDA compatible projector and start having fun from the get-go? I did, for ~$800, shipping incl.
    Hope this info helps to light up your life with lasers.
    BR

    hey pm me i would be willing to take those from you if still avail. located in the us. Hey TheHermit. sure you can buy a laser to play with but it depends what your after. some like the side of programing shows and playing with code and soft where and some like the side of building something. i enjoy both but the planning and production building a laser and overcoming the failures is fun for a hobby person. its like a nerdy model rc car type of project. and also good price for the scanners. u can buy a laser for cheap but building one with stick with you for longer

    Agreed. Back in the day, my forte' was building gas ion road systems, while some electronics gurus build the control desks. So, I rebuild my own wall mounted projectors for my home, anyway.
    Only making the point to others who may not have my experience that it's just as expensive to DIY using the same components as it is to go ahead and purchase a working projector with a warranty.
    If starting out and on a minimum budget, then the 'el cheapo' stuff is a great place to learn what not to do, without killing a pair of DT-40's in the process. That's why I started with inexpensive projectors with attractive cases for my living room walls and that I knew I'd need to mod them.
    But, neither the galvos nor RGB modules were up to my personal standard, again as a previous show pro. I'll repurpose the cheaper LDs for an RG,GB,BR 3 beam lumia projector with multiple effects wheels.

    OPT W3000-RGB & DT-40s are looking great, for a fraction of Kvant. but, of course, if I were still a pro, making a living and upholding a reputation, I'd fork out the cash for a Beyond & Kvant rig, mostly for the safety compliance, which I don't need at home.
    Different strokes for different folks.
    Instead, I've abandoned LSX & Etherdream3 DACs and am developing my own MIDI controllable Teensy laser synth for abstract lissajous cycloids, just like the good ole days of Laserium.
    Don't see where we're in disagreement.

    What goes around, comes around. You are in control of both. People reflect what we project.

    Apologies for not updating this thread earlier. I haven't been on this forum as I have taken a break from building lasers and writing content for a couple years now.

    As it turns out I had two sets of these, one of which was in great shape and another that had a driver that would 'lose it's sh!t' occasionally. It was acting like the protective electric 'fuse' (I forget what it's called) was malfunctioning. The later set I offered to someone for free, but accidentally sent them the fully functional set. I still have the set that needs repair if someone wants that - just pay the shipping from Fort Mill, SC.

    As for buying new - I'd look at the ScannerMax Compact 506 and Saturn series. They perform significantly better than anything I've seen including the pricey and hard-to-find CT scanners. I migrated the remaining of my 19 custom builds to Saturns and C-506 series scanners some time back and couldn't be happier with their performance and reliability.

    To further some of the recent comments, I believe someone taking the time to build their own lasers for home use only has a few 'avenues of distinction' to build something that they can't buy for less. These areas include:

    1. Single mode diodes for exceptional beam overlap. Yes, you'd be limited on power, but for home use or graphics single-modes look awesome. They are also more practical than gas or OPSL options.
    2. High-end galvos (Scannermax) for either beams or graphics
    3. Custom lumia capabilities
    4. Custom cases for an unusual form-factor / footprint requirement
    5. Use of uncommon diode wavelengths (e.g. 405nm for glow in the dark work)


    Of course, building your own is still fun and educational even if it doesn't save you any money.

    Hi David,

    I'd be interested in picking up the malfunctioning set of DT-30 galvos if prosnurfer doesn't want them.

    Thanks,
    Kyle
