My first Blu-Ray!!!!(Pictures Added)

50Freestyle · Aug 31, 2008

Wow this thing is cool! Constructing it was more frustrating than I predicted and took 4 days

, but I finished it and it is working. It is an 803t diode running at 125mA with an rkcstr fixed output driver. I used the old 5W MXDL host to put it in, the two CR123's give more than enough voltage to the Blu-Ray (8.4V). Oh it has one of Jay's heatsinks in it too, they work great and make the laser look alot cooler ;D.

I thought the hardest part would be hooking the diode up to the driver, turns out that the hardest part was trying to connect the driver and diode to the MXDL. The problem occured when I had this stupid idea of pulling off the blue wire completely and soldering the driver directly to the circuit board, it turns out that the wires from the driver were a bit too stiff so when I would get a good solder connection I would try to put everything into place and the wires would bend and snapp right off the circuit board. I kept trying and eventually I ripped off the positive contact by accident, this pissed me off because I wasn't able to drop a blob of solder where it used to be because the solder doesn't stick to the circuit board. After I had almost given up I took the wires right off of the driver and put on some stereo multistrand wires (The kind that are used with earphones) that were incredibly flexible and small. I also ended drilling a small hole right through the middle of the circuit board so I could attach a wire directly to the posetive contact.

Through all of the burns and cuts I finished my first Blu-Ray and right now it is sitting on my kitchen counter wide open so that the silicone can dry and hold all of the wires in place.

This thing lights up as one of the most beautiful colores I've ever seen. I found something even cooler about it, when I shine the beam through my fish tank the beam is actually a very light blue-green color that looks just way too cool. The most odd thing I find about this is that then the dot is unfocused, it makes an oval shape. This thing burns like none other, I went and put it on a pure white balloon and it popped instantly. It really badly stings skin too even at long distances, with my red DX200 I have to put the laser on something stable and make sure it does not move to burn my skin at far distances (And even then the burn is hard to feel). I think my eyes have something wrong with them too, I can see the beam on this thing almost just as well as my DX30 greenie

.

Thanks for reading this terribly long thread and thank you everyone on this forum for teaching me so much!

post some pics and beam shots ;D

Re: My first Blu-Ray!!!!

I fried two of mine (blurays) by letting them get too hot. One I left on next to me while I was sleeping. The other one died while I was burning pictures in to wood while camping. It was hot that day and my fingers where hot as well. Bluray is my goto laser. The 250mw green is fun for its beam but the bluray is like Circe de sole is to watching tv.
Thanks again Igor!

Re: My first Blu-Ray!!!!

I try to be careful with mine, I give it a huge duty cycle. Its like 30 seconds on and 1-2 minutes off

. I make sure that no wires twist or the laser gets bounced around. I expecially enforce my guidelines onto my buddies when they want to use it. I really love this thing and people are amazed by its color, none of my family or friends knew there was another color of laser besides red and green.

Gimme a sec, I'll be posting the pictures today.....Hopefully my comp can load them

Re: My first Blu-Ray!!!!

yeah its good to be careful but i have been pushing the limits with some of my blu rays and havent had to many problems....... 30 seconds is not enough for me

Good job! Very clean...

You have done a professional job and have a great looking bluray! Well done.
Try running it over some peanut butter, in the dark. The peanut butter will fluoresce green for a few seconds where the beam hit it.

50Freestyle · Sep 4, 2008

Thanks for the compliments, it really feels nice when people say good things about something that took some frustrating work to build. I haven't tried the peanut butter trick but I found something very odd that is very similar to it. When you shine on concrete sidewalks or driveways during the day and move it around you can see a mossy green trail behind it. Thought my eyes were playing tricks on me, guess not.

Last night I took it outside to look at the beam again and I was trying to focus it down to a really thin beam, I focused my eyes really hard on it to make it really thin and I ended up seeing two beams. I was really lightheaded after that.

OMG you are getting laser poisoning ... stop all use of lasers immediately... the effects can not be reversed if you continue!!!!!!!!!

Quick question...how do you get 8.4v's out of 2 cr-123's? Aren't the CR-123's 3.0 or 3.6 volts each. The reason I'm asking is I would also like to use the MXDL host to mount a PHR-803t with a rckstr adjustable driver but I was thinking 2 CR-123's wouldn't provide enough voltage and therefore would be using a 9 volt battery instead. But I don't think the 9 volt will fit. Any insight? Thanks,

jayrob · Sep 4, 2008

The 3.6 volt RCR123 rechargeable batteries are 4.2 volts at full charge. If you are going to use a FlexDrive, you cannot use a pair of these batteries, but can use a single 3.6(4.2) volt battery.

Although I have not used rkcstr's driver, I believe that 2 X 3.6 will just be enough for a blu-ray.

I have used rkcstr's 'Driver test load circuits', and I just want to say, that they are very well built and are a perfect tool for setting current! (plug for rkcstr - good stuff there)

Thanks Jay...so what is the best host for using an 803t and rckstr's driver? Right now it is powered by a 9 volt battery but I do not know of any nice looking flashlight type host...do you? Also, would a MXDL with 2 CR-123's be enough to power an 803t?

I believe that the sku 4171 host using 2 X 3.6 volt rechargeable batteries would work with rkcstr's driver and a blu-ray diode.

The other thought would possibly be a host that takes 3 X AAA sized batteries (use 3.6 volt 10440 batteries) The only thing is to make sure from rkcstr, that 12.6 volt max is not too much for his driver.

For AAA hosts, I have used three different ones. The sku 3405, sku 5095, and sku 46.
Not trying to 'threadjack', but here's a couple of blu-ray tutorials: (In the tutorials, I use a FlexDrive, but a rkcstr driver may be used with 10440 batteries - check the voltage max. with rkcstr)

This is what is good about this hobby -- someone builds, learns and shares about a project. Too many people anymore just want to acquire.

WackBag · Sep 4, 2008

Thanks Jay...as usual your help and advice is first class!

Oh...I just thought of something. If I used the 10440's with Rckstr's driver could I place a 1n4001 diode in-line with the positive side of the battery to reduce the voltage below 12v's?
