Introducing STINGRAY-3 Development of the "Hercules killer"

Here are some pics of the progress. Finally got back to it and did the wiring, and some more machining.

As you see, i put some air intake holes. That came out not as pretty as i hopped as i was rushing, and because i decided to drill them under angle towards the front of the laser (in direction of air flow)

I replaced the fan with quieter one, and cut off a ring in front of the switch, which i replaced with newly machined one. This I did for purely aesthetic reasons, so it appears same width and angle as the front cone.

Fan works nicely, and is pretty quiet now. I wired it to a 5V voltage regulator, and it will run only when switch is pushed to a constant ON position. When switch is used as momentary on/off fan does nothing.

Next time i post, there will be coherent light.

cheers

New air intakes:

New ring to achieve desired shape.

Internal wiring. I made wires long enough for easy disassembly All are AWG24 silicone shield. 5V DC voltage regulator (covered with yellow gaff tape) takes power form battery and feeds 5V to fan.

I did a bit of aerodynamics improvement on driver board with epoxy so air wont hit flat walls directly.

Happy coupling molex style for easy disassembling.

ZOMG! :drool:

I missed this earlier in the month


VERY nice

+1

Let's get that rep up into three digits ;)

Peace,
dave
 
Also missed this one before :thinking:

Looks like a great host to keep the 638nm we have these days cool and lasing at at lower, more visible wavelength!

+ :gj:
 
holly shit! i could really see someone trying to load that into a RPG! +1
 
Thanks guys!
Actually, i've been into military airplanes as long as i can remember, so picture of something like this (below) was on my mind when placing the exhaust holes :-)

these rocket launchers always looked like great heat sink to me :-)

cheers all !!

I only just seen this now, very cool laser you have made and with forced air cooling, over the top +3

I like the over all shape of it and you flatter me as it looks very much like one of my custom focus adapters The HYDRA > http://laserpointerforums.com/f64/fs-custom-focus-rings-any-build-52448-5.html#post730873

Keep up the good work man :beer:

Thanks man. I have not been on the forums much in recent years, but I did notice your avatar :-)

To make clear, this is one and only. I do not intend to produce more.

more beam pics and specs to come.

cheers
 
Just saw this thread today. Amazing!
I can't imagine the hours you've put into it though.
 
most of it was done during my lunch hour break at work. Many lunch hour brakes. Its hard to get anything done in 1h at the time in machine shop. Sometimes it takes 30min just to set up lathe in different way.
We have small machine shop, (not maintained at all for decades). Otherwise its a camera / service / rentals, and sales business. Lots of optics :-)) !!!

Some of the additional modifications:

- Added mounting plate on the bottom with 1/4-20 and 3/8 standard threads formounting options.

- Machined off rounded end of back cap and added 6mm thick steel flat ring arround key switch. Now laser can sit on its back end on the table.

- Added locating pin and a groove for easier dissemblance when i want to take it apart.

- Spray painted everything behind anodized front end with two primer, and two coat semi gloss black paint.

- Made a new stand combining a round base mic stand with camera ball arm mount, with quick release plate. Painted same as laser.

cheers
 
Good job Milos, good to see you back and with a solid build... One for the record books I'd say.

I know you said more specs later might I ask what diode ur using. I read the thread a bunch and still missed it also look up you tube on the Herc. I remember a vid a kid did with smoke for a test seems the exit for the fan is in the sink grooves.
