This will be very very cool to see when its done, if you have a RC model car/plane/HELLICOPTER place close to you then you may want to take a look at the assembly to control the rotors, a swashplate I think its called. you might find one usefull.

Re: Hex DIY Red Laser - The ULTIMATE burner idea!

 Just mount the Aixiz modules in a circle, on a flexible disk, and pull back the center of the disk.  I was going to draw this, but my software doesn't want to open.

Make a thin spring steel disk and cut slits inward to divide it into 'petals', one for each diode.  Bolt an Aixiz module in the center of each one, perhaps with a thru-hole peltier on the other side of the disk behind each module.

Add a shaft attached to the center of the disk with wide washers, such that the petals extend out from the washer and the steel does not bend at its weakest point in the center, but rather a few mm out.

Run this shaft to your pistol grip, such that squeezing the bottom of the grip pulls the shaft towards you and deforms the disk inward.

the petals' big ends should rest on a pipe end so they are loose, but cannot move backward.  A second disk should probably be mounted behind all this, with an OD the size of the pipe's ID, to keep things concentric.  If the apparatus gets off center, some petals weill bend more than others.

Any differences in flexibility can probably be trimmed with a needle file to arrive at a nice focused pattrn on the target.

I'll try to produce a diagram in the next couple days.  -o.r.

  OK, here's the diagram.  Most likely the only part of this that would need to be CNC'd is the petal-cut flexible disk.  Maybe the centering disk too, for precice control of diameter - it should fit almost snugly inside the rear tube.  I stuck hypothetical thru-hole peltiers behind each module in case someone was interested in that.  Everything else would seem to be readily available hardware.

 Basically, when you pull back on the shaft, the parts of the petals that aren't restricted by washers will bend to form it into a parabolic sort of cross section.  That's why you can only have one circle - modules further in or out would not converge on the same point - you'd need a spherical profile for that.

 Obviously the individual petals need to be symmetrical, including holes and loads, to prevent sideways twisting.

 Once I get my second clutch of diodes, I will be interested in having a few of these disks CNC'd if the opportunity is still there.  -o.r.

I have been reading this thread with great interest but it is giving me a headache... ;D So many great ideas.

Rog, you are almost there!

Re: Hex DIY Red Laser - The ULTIMATE burner idea!

a swashplate I think its called

@LC yes it is a swash plate, they are used to transmit movement at a constant angle on a rotating shaft (I once made a swash plate hot air engine) the LD's need to move toward the centre at the same time......I feel a new thread coming on though, you could use a swash plate to adjust the angle of mirrors on a spiro projector whilst motor is running

@O.R Not sure about the peltiers but the flex plate should do the trick, are you going to try a build?

@G My worst problem is the angle at which the laser beams emit from the modules...I marked them all to get the error radially in the same direction, I chose to converge them, I may try to turn them all through 180 deg's so that they naturally diverge then they won't cross over so close to the mount...if you see what I mean....

Re: Hex DIY Red Laser - The ULTIMATE burner idea!

Has no one said how cool that pic looks, so far?

The thingus you built, it looks AMAZING! That is some cool stuff. And besides, it works!!!

Well, cool stuff!

That is some AMAZING stuff you got there! ;D

VERY nice work

 Eventually.  I'm pretty slow though, I'm wondering if maybe one of you hot rodders will precede me because it might be a couple months on this end.  =)

 I will probably omit the peltiers, as I am a cheap sumbitch.

@G My worst problem is the angle at which the laser beams emit from the modules...I marked them all to get the error radially in the same direction, I chose to converge them, I may try to turn them all through 180 deg's so that they naturally diverge then they won't cross over so close to the mount...if you see what I mean....

 Can you trim them with setscrews?

 I'm starting to think along the lines of heat setting polymer clay for trimming the base direction on mine, something like super sculpey, so the modules can be pointed to converge by hand and the assembly put in the oven for curing.  You might be able to do the same depending on your central cone geometry, especially if you use a thin metal plate on the coneward side to make a sculpey sandwich.

 Do you know if the stonetek modules have glass lenses, or plastic?

 Fantastic work, BTW.

Re: Hex DIY Red Laser - The ULTIMATE burner idea!

Wow that is awesome man. You should focus all of them real fine and burn the heck out of stuff. ;D. But yeah that is some amazing work you've done. Nice job.

My next job is to make seven adjustors to do the presetting. they will screw down to touch the cone......

Once again Rog. Very impressive

Re: Hex DIY Red Laser - The ULTIMATE burner idea!

If you can trim with set screws then I think you will have done it ...

Re: Hex DIY Red Laser - The ULTIMATE burner idea!

Are you going to eventually try and get 1 beam out of all these? That would be crazy.

Re: Hex DIY Red Laser - The ULTIMATE burner idea!

I'm certainly impressed. I wish I had the initiative to make something like this. Keep it up

Re: Hex DIY Red Laser - The ULTIMATE burner idea!

I'm away for 3 days, and look how much progress you have made!!!!

Brilliant!

Now I'm back, I'll be able to whip up some designs + post pics.

@ Rog: How did you get so many modules so quickly? I'm on tenterhooks here waiting for my modules so I can get cracking! I wish I had ordered more....

Does anyone in the UK have some stock Aixiz the same as senkat is selling that I could buy off them? I've only ordered 5, and that was before I started this project.. I would have ordered a dozen or so, but us post takes ages. :-(

I'll need about another 3-5 to buy. I'm willing to pay the price + 15% and full 1st class postage to my house.
I can't wait to get my lens idea started!!!!!!

@ O.R.: I love that idea, it's really quite possible. I'm just currently thinking of what material would be a good candidate. I'm currently thinking thick rubber, say 8-10mm sheet, with a 50mm dia? I'm sure you could try a tennis ball (through a bandsaw) as that is about the right thickness, but it might be too stiff to use. BUT most people have some lying around to mess with.

I'll muse over that idea a bit more later....


@ Death Angel: Read post 1! - Yes!
1W+ of power ;D


@ DDL:
If the death ray works, I'm planning on making a White death ray, (SenKat + Aixiz green + DDL's PS3 Diode modules) + an RGB driver circuit
But that's well into next year, (i'm sure I've mentioned that before!)


I'm still working on the maths of the lens, to see if it is worth pushing that idea.
IF the lenses work, then the only mechanical part would be the final lens itself moving up and down, hence making the manufacture more easy. Essentially creating a HUGE 1.4 Watt Aixiz Module that just plug and plag. However I do like the idea of a highly mechanical correction system.

Anyway...
I'll catch up with you all later.

Re: Hex DIY Red Laser - The ULTIMATE burner idea!

Hi again,

I've drawn out an idea, I can't remember who suggested it, but I've put it on paper.
I'll hopefully draw this in CAD later this week.

OK, the drawing is not to scale, I've enlarged parts on purpose to show how it fits together.
Basically you have an aixiz module that is pivoted in the middle, as a kind of gimbal. Then say on the lower part of the module, a spring that is pushing against it. The other ends of the spring push against the centre hex post for stability.

Then at the other end of the aixiz module, there is an adjustment screw, which you can use to alter the angle of the module. Think of the whole setup as 6 mini see-saws. This allows individual control of modules position, but would be VERY tedious to align. However, you could set it for 50cm and leave it...

By using the tension springs, hopefully the modules should remain in place.


As an after idea, more for when the thing is built: When you are positioning the diodes, you could add sep. switches to the circuit, perhaps a DIP/DIL switch, to allow turning individual modules on an off. For example, clamp the death ray in a fixed position pointing at a wall a fixed distance away. Then put a coloured dot on the wall and match each module to that dot one at a time using the screws and switches. Then switch them all on and.... the wall dissolves!  ;D


Let me know what you think. I could start building of the array assembly this week, ready for the diodes and housings!

Edit: I just realised that this looks like a particle detector from the LHC @ Cern (I think it's the Atlas detector)
Lol! I hope it's not as complicated as that!
