The SYNIOSBEAM - CFT90 recoil thrower

Impressive stuff! Perhaps the folks of Mercedes are actually Illuminati? :smiley:

Subscribed! Will be fun to see it’s performance as compared with a Maxabeam.

I meant polishing it before you anodize it. You will still be able to see the difference.

Haha thanks :stuck_out_tongue: it does look like their logo doesn’t it…


:slight_smile: Can’t wait!


Ah ok, I will try to remove scratches and stuff with a scotchbrite pad but I think the anodizing place also offers some surface prep before anodizing, maybe I can get them to polish it for me.
Do you think polishing will make a big difference compared to just brushed?

Do you own a maglite? Those are somewhat polished I think.

What are your thoughts on the Maxiem waterjet? I’ve run an OMAX for a long time and Maxiem is what I guess you would call their value brand. The software looks to be almost identical which I would expect. They’re fantastically versatile machines that will cut just about anything, though I was defeated by a piece of carbide.

Yup, an old 4D one :stuck_out_tongue:
I think if I try polishing it then the flaws will become more visible.
Maybe for a future more refined prototype I can try doing that.
If everything is turned on a lathe and milled perfectly it would look best, which I didn’t do on this prototype unfortunately.


Can’t really give a good opinion since the one I used has been mistreated and screwed up plenty of times by kids who don’t know what they’re doing.
But from my personal experience with this one, it is less accurate than the regular omax waterjets which I’ve also used previously.
If you just need quick cuts at large size then the maxiem works great for that.

BUILD PROCESS - chassis

Almost done with the flashlight body, everything fits!
Only things left to do is clean up the surfaces with some scotchbrite and remove scratches.
With the body finished I can start working on the cooling and electronics.
Here you can also see the handle on the light, as well as the 6 screws which will hold the glass on the front.







Hmmm… Enderman I really did not think that you are crazy scientist but you obviously are… :+1:

:smiley: Thanks!
It will get more crazy, don’t worry.

My kinda guy!

BUILD PROCESS - chassis finished

So all the aluminum parts been cleaned up with a lot of scotchbrite pads to remove small scratches and hand oils.
I think it looks pretty good!
Overall this is as much work as I want to do on the body (at least for now) so I will start working on the cooling system and electronics.
If everything goes smoothly we should be able to get some beamshots next week! I’m excited :smiley:









did you see the other project with laser pumping the LED additionally?

in recoil this would be even easier to achieve than on a regular reflector light

Yes, it is not a good solution.
If you want to use laser it should be directly to a heatsinked phosphor, preferably single crystal, not an LED.

This project is not for laser, it’s LED only, I have plans for future projects that can use laser.
Not only is it less safe but it costs several thousand dollars for the lasers and crystals alone.
Also won’t count as an “LED” flashlight/searchlight, which is hat I’m currently trying to break the record of :slight_smile:

Its like a wavien collar increasing the output and intensity of the LED

By almost nothing, since the LED is already running near the limit of it’s heat transfer capacity. Laser-Phosphor-Erweiterung von Projekt Excalibur | Taschenlampen Forum
A wavien collar actually gives more than 2x increase.

Any useful amount of laser power is just going to speed the burn up of the phosphor.
This is why the phosphor needs to be directly heatsinked.

How much more we need to wait for miracle beam?

You know about that $ I was talking to you? You will have easy 100 pcs order all over the world if you’ll not put to big price on it.

Making money with the hobby you like is the most wonderful thing. Product made with love is the best product :+1:

Well what a coincidence, I was just uploading the images from last night! I’ll post them in 5 minutes.

The problem with selling this at the moment is that the parts alone cost a lot, and on top of that it is a lot of work :frowning: It wouldn’t be affordable at all.
I am however constantly learning ways to improve the design, make it easier to build, cheaper, etc.
So maybe one day I can make a very affordable 10+Mcd flashlight :slight_smile:

BUILD PROCESS - liquid cooling and first test

So I finally got around to installing the liquid cooling and LED to do the first test.
Filling the cooling loop is not very difficult, the self-priming pump makes it really easy to get water flowing, then all that’s required is to put both tubing ends under water and join them, that way no air bubbles get inside.
One problem I have at the moment is that the water pump is getting extremely hot, so I need to find a way to heatsink it to the body, I guess 30ft of tubing adds a lot of restriction!
The flow rate is still very good though, the tiny pump has no problem moving the water since it is not an impeller pump, it uses a diaphragm.


Here you can see the coil in place. It is not attached to the body with thermal compound, but I plan to do that only once the body is finished and anodized.

These are the screws+springs that are used for mounting and focusing the reflector. They actually worked very well in my testing at the end of this post, however the screws are a bit too short so I will have to increase the depth of the countersinks and add some washers to the springs.

Test fitting the reflector.

I only have 3/6 of the batteries in, but the black shockli cells look awesome :slight_smile:

Here is the small pump used for cooling. This is what is currently getting very hot after a few minutes and needs better cooling. How ironic, the pump used for cooling is what needs the most cooling.

The light is jam packed with wires, tubing, and batteries. In the future I need to allow for a bit more extra room in my designs for ease of assembly!

The LED mounted on the cooling block, mounted on the spider. So far 0 leaks :slight_smile:

Screws holding the MCPCB are too thick, and block some of the light, so they will be replaced with some lower profile ones.

I used the 1 amp DMLN Synios LED for this testing.

Test before putting the reflector in.

Mounting the reflector is probably the most difficult part. The copper tubing unfortunately only lets it fit through the front of the light, which means it is not possible to see where the screws and screw holes are to line it up. If there was no liquid cooling it would have been a breeze. Design flaw :frowning:

Despite all these small problems, the light works!

First beamshot! (not focused perfectly because of the screw length I mentioned before)

Great shot! The very slim central core of the beam is visible and looks very laser-like. Your shot directly above minus the beam, looks like it could be a Christmas card. It’s very warm, pleasing and “home’y! Can’t wait to see the beam focused on a clear, dry night.
