Default My New Pocket Blu-Ray

I've been working on this on for awhile. Usually more thinking than doing. However, it is finito

Introducing my Pocket Blu-Ray

The host is a Dorcy 5mm LED.

http://www.dorcy.com/products.aspx?p=414224

Originally it used one AAA battery to light one 5mm white LED. I have been carrying this thing around for years. I kept it in my shaving kit so that I would have light wherever I went. Ever since I got into lasers, I've been eyeing this host. It was only after the flexdrive came on the scene that the idea came to life.

The completed unit uses a single 10440 3.6V cell, powering a flexdrive. The diode is from a PHR-308t sled harvested from a Toshiba SD-H802A DVD player. The tail switch is a "momentary" type switch, but it can be screwed in all the way to make a constant contact. It has an acrylic Sure lens with the back opened up. The finished laser (with the extension for the module head) is 3 3/4inches long (9.5cm). The bell is 3/4 inch in diameter (2cm). The battery case is 1/2 inch diameter (13mm).

Here it is in its original form




Here are its parts




Even as small as the flexdrive is, I had to sand off the corners and open the host's bell a bit




The bell didn't have enough room for the driver and the module, so it became necessary to make an extension. I could have gotten away with a simple "washer" interface, but I like the look of this more. The module is chrome and the corners would have been more "square." This flows better for me.




I used the original board only for supporting the + contact spring and wire. I soldered the - to the little "ring" that went between the board and the bell. Here it is with the power source sorted out




Here's the flexdrive wired in and hooked up to the dummy load. I set it to 90mA. I want this to last




Here is the diode hooked into the flexdrive




The completed unit




A different perspective




We have light




LOTS of light!


TAAA DAAAHHH!!!

Nice job! A little pocket rocket
I have been lasering for less than a year and it is amazing just how far we have come in that time with the experiments and builds shared by the members here.

Keep em coming!

I ran it up to 3 minutes without any appreciable heat using the very precise and well tested "lips to the module" test.

I'm using the flexdrive set at 90mA. It has an acrylic lens with the back opened up.

Nice tight package. I like that you saw it's potential and waited for the right components to come along (Dr. Lava & BluRay).

Remember, all science is based in what we can perceive with the five senses.

I'm just a little closer to the heart of science than some
