x paul1598419: the only method will be to measure one diode at a time. My sensor cannot sustain more than 20w and my Laserbee can read max 7 watts ... xRedCowboy: I'm interested about this LiPo issue. I do not want to fry 9 diodes all together! I will use the classic SXD driver mounted on the...

x RedCowboy: this build is not intended to be used for more than 10 seconds, but I have plenty of space inside the battery compartment to add a fan in the future! I will use this kind of lens: https://www.thorlabs.de/thorproduct.cfm?partnumber=ACL7560U-A I could use only one lens to move the...

I'm sorry DTR forgets my rude expression. By now you have got used to (and spoiled) your speed of response so we often take everything for granted. :beer:

Hmm the new NUBM44-81/NUBM47-A1 diodes have 10% more power compared to the previous model and yes, I will have <5% of total power loss, so the real output should be around 65 watt. Enough to cut a cutter LOL :whistle:

Hello forum. I started another ambitious crazy project called "Blue Katana", a "portable" laser with 9x NUBM44-81/NUBM47-A1 450nm diodes. Since the beam diodes angles cannot be tilted, this will be a build suitable only for short focusing. I plan to reach a focusing range from 1/2 meter to 10...

Phew happy to hear You again, DTR! I cannot build anything without Your diodes !! :D

Thank You for the hints, but first I need to know if I can obtain/receive what I'm looking for. Usually DTR reply me thru mail in 24 max 48 hours. I have sent him a mail 4 days ago and a PM here. It sounds very strange to me that he do not respond about a simple question ... Surely I do not...

Hello forum. I need to buy a lot of material from DTR but I never receive response from him. I tried by mail, I tried here by PM .. nothing. He is not in holidays because I can see a recent activity of him in the forum. It seems that he want to avoid me and I cannot understand the reason...

Hi forum. I'm back :na: Lately I have spent a lot of moneys and efforts to become a decent pyrotechnician, so I have missed this forum and also abandoned the laser passion. But I will return in September with a new laser build, this time made 100% by me. I had a great master like CDBEAM777 that...

Marvellous piece of art, congrats CDbeam and Alaskan :beer: I missed it in my huge collection LOL.

Hello forum. This time I returned to illustrate You how I learned during this months about the wonderful pyrotechnical world. The following procedure is the result of many different techniques that I have learned surfing many forums over internet, and with the help of a great friendly and...

To found the better distance from the two corrective optics I applied the well-knowed method TRY AND ERROR. First of all I firmly glue the first lens, then I begin to move backward/forward the other lens and observe the dot shape against a wall at least at a distance of 10 meters. When I found a...

LOL, the probe is a very small and simple sensor that come together the 8A blackbuck driver. If connected, it checks the temperature near the diode: if it reach a certain amount, the driver cut off the current and allow the heatsink to cool. It is a nice diode protection. It is not necessary to...

Hello. Yes, this time I did also the H-BE (host to Beam Expander) with a CNC cutter. In a (near?) future I think to build everything. I have learned much lessons here, especially from CDBEAM777, that will always be my greatest teacher. But there are at least two things to curb my desire to do a...

Re: Indigo Imperator - A 6500 mW 450nm Monster Optical Corrected With Thorlabs 3x BE Hi my friend! Yes I disappeared for many reasons. One of them was this build LOL. Wow I see that You are now a Super Moderator .. my best wishes! It seems that I missed a lot of news lately :o

Hello forum. Yesssss .. another painful and suffered birth came to light! This time me and CDBEAM 777 met a very big dose of problems and issues. A considerable amount of misfortune has also intervened to complicate our existence even more. But now the masterpiece is ready to be unveiled. As...

The first launch was with a rocket only without any shell attached. It was only a test (in a perfect North-Korean style lol :D). It starting so fast that I lost the rocket. Only the second was launched in the NYE.

This was a very impressive launch of a 750 grams supersonic nozzleless rocket: This was the same rocket with on top attached an heavy 5" shell for a total of 1500 grams: I used a professional Alphaphire radio-controlled ignitor from a distance of 50 meters. With these beasts it is better...

Hello forum! I have worked hard lately, for a new incredible handheld laser project and for my 25 kg of pure pyrotecnic juice :D Take a look here: Cakes apart, all the rockets and the shells are completely designed and build by me myself :rolleyes: There are many interesting news, suck as...

Added some updates at the end of the first post :)
