2 x green ILDA laser

[tomme6]

Hi all!

I am relative new into lasers and I bought a Laserworld CS-1000 laser a few years back.
Since a couple of weeks i bought a Riya dac allong with a Spaghetti license and what a difference was that .
I know there are a lot of people that are not so enthousiastic with Laserworld but it fits my needs; small venues and hobby

Now i am looking for 2 sidefill green lasers. In the past there was the CS 250 series wich had ILDA and were pretty cheap. Nowadays nothing in this pricerange is available with ILDA.
So, i am looking for 2 green lasers, with ILDA, used or new for appr. 300 - 400 euros.
Do you guys think this is somehow possible?

Best regards,
Tom

Where in the world are you located? Update your profile, and it will be a lot easier to answer this and all your future questions. If you are lucky, a member here are located near you, and are willing to share knowlage in some basic building of projectors.

300-400 Euros does not go a long way, but you still might be able to build a couple of simple low power 532mn green beamprojectors.
Do you have basic electonic skills you shoud be fine. There are several threads on PL to be read about the topic.

Good morning!

I am located in the Netherlands My electronic skills are a little bit low, but always eager to learn.
A friend of mine is a pro in electronics, so that should not be a big problem and therefor building one myself is one of the possibilities!

One of my major concerns regarding this is where to get wich parts. I did not find any topics with some pre-designed lasers, but perhaps i did not search very well

Hi Tomme6

Drop me an email on lm@laserworld.com I have a couple of single green projectors that are discontinued you might be interested in.

Many thanks,
Lee

Hey Tomme6,
My name is Saifer Song, I work for 520laser.
You can contact www.520laser.nl for the green laser with 520nm Green.

Tks!

I am currently in contact with several companies, but none of them have what I am looking for So i am also curious to the options of building a laser.
Are there any standard designs withing this price range?

[Datsurb]

I`m not aware of any standard designs for "budget" lasers.
But i can give you some clues to what bits and pieces you need to buy when building yourself.

In your first post, you stated that you wanted a couple of green satellite projectors. I recon this will be used for beams and not graphics.
Beams require less, and the parts can therefore be cheaper. You have not stated what powerrange the green should be, but to balance the cs 1000, i guess a 100-150mw green will be enough. When building yourself, changing the module and driver for a more powerfull laser later, will be a piece of cake.

So to the bits and pieces.

Safetygoogles for green lasers. IMPORTANT.

Chassis. You need either to purchase a finished empty box, or make one yourself. No limits what so ever, but make it big enough, and have the baseplate solid. The baseplate have 2 important functions. The first is that it make a solid, steady platform. Second is that it also is used to dispose heat like a heatsink. The second is probably not so important for these lowpower green beamers. I have made a couple of projectors in plexiplastic with only the baseplate in metal. 10mm aluminum pre cut to 25X25 cm. Plenty of space for a single color laserprojector.

Galvos or scanners. These can be found cheap on ebay, aliexpress etc. For beams, you get away with 20K if you don`t plan to scan to wide angles. The higher speed, the higher price. The higher angle, the higher price. There are a lot of galvos/scanners that are sold with "ilda kit", included. I know there are a lot of members hating this, but for my first builds, they were a lot of help understanding how things work, and made the hookup easy. The kits normally includes the ILDA chassis connectors, a "showcard" for hooking all wires togheter. Dont use the DMX plugs and function as you have next to none control of the laser with DMX.

Laser module. There are plenty out there for a reasonable price. You probably know the difference between TTL and analog drivers. For beams a 532nm modules will work fine and they are cheaper than 520nm in that powerrange. You could also build your own lasermodule, but we leave that for now.

AC to DC powersupply. Most common is 12V output, but you need to make shure it suits the drivers for the lasermodule. A 5 amp is OK.


You also will need some smaller bits and pieces.

Female chassis 220v connector plug with fuse and on/off switch. Plenty to be found on ebay etc.
DB9 male chassis and female plug for the estop
Keyswitch for safety
Selection of wire and connectors
Drillbits
Tapping bits.
M3 and M4 bolts
A couple of chassisfans 60X60mm 12volt for cooling with dustcovers

Soldering iron - multimeeter - tools to mark up baseplate before drilling and tapping.

A cup of patience, a teaspoon of engineering, and plenty of time, and you are there.

Please bare in mind that using low shelf components, never will result in a legit certified laser, but as a private hobbylaser, it can do just fine.

Some of the components can easy be harvested from old PC`s, etc. Fans - powersupply etc.

Happy building.
