    The Adjustable Voltage Regulator

    I don't think i can post links yet, but I thought this might come in handy for some of you. rason.org/Projects/regulator/regulator.htm

    White laser

    I'd suggest you go buy all of them cause you'd be able to sell white lasers for probably $2000-4000 here...

    Was bored last night...

    I sort of have some lever action going on, but because the drinking straw I used is much larger than the axel the bottom of the mirror is still able to move too much... Still not 100% happy, but I glued some 1" square craft store mirrors over my shiny plastic and now I have finished my senkat...

    New 337nm Laser Diodes Being Designed

    With a scanner and enough patience you could have a customized tan...

    DIY Homemade laser diode driver

    Just a note for anyone building this circuit, If you're using a pot in your design and a "safety" resistor. Make your safety resistor a little smaller than the suggested. Example: For my red laser the suggested resistor is 5 ohms, but because the pots never quite reach 0 ohms you will never...

    DIY Homemade laser diode driver

    Completely the wrong thread for this, but. My MBP is 2/3 the thickness, nearly 2 lbs lighter. Has draft n wireless and windows. It also has bluetooth. It doesn't need turbo memory to boot fast, unless I'm booting into windows. Your laptop has no OS X no IEEE 1394b. I already own a backpack and...

    DIY Homemade laser diode driver

    The lantern batteries are just temporary until I can afford something better. I'm afraid my bank account is low ever since I purchased my macbook pro. I'm quite happy with the 8600m gt with 256mb. Plays any of the games I throw at it. A great improvement from my fx5200 with 128mb.

    DIY Homemade laser diode driver

    Question of the day: Why does radioshack put stand offs in the bottom of their project boxes, when none of their circuit boards have holes in the right places to fit? The heatsink was ripped off an old motherboard. It still had a little bit of thermal tape on it and i wrapped some wire around...

    DIY Homemade laser diode driver

    Everything fits perfect in the 1"x2"x4" enclosure from RS. Just needs to be drilled for power and the aixis module. Crossing my fingers that my package from senkat arrives tomorrow. I ended up going back to RS to get a pcb so I picked up a 47uf electrolytic. No switch yet since it'll just be...

    Was bored last night...

    The problem is I can only turn the speakers so loud before they start distorting and making the laser blurrier than it already is. That's why I need a better laser, real mirrors, and better speakers. From about 15 feet away I can only make about a 6 inch image. Hopefully with my senkat diode I...

    Was bored last night...

    This project was kind of rushed. I found out about Laserline yesterday and wanted to give it a try. I will take more pictures when I have a better laser. These were all taken with a $5 pointer from Radio Shack. If the postal service hasn't made a mistake my diode from senkat should be here...

    I made this video, but the laser is too dim to see the big circle just the small loops rotating around.

    This was made using LaserLine on my mac it's a simple spirogram, this was the best picture I could take, even better than the ones with the flash off, oh well.

    So I ripped apart an old boombox and put the speakers to good use

    DIY Homemade laser diode driver

    Size isn't an issue for me. I just want my first laser to work nicely. I found a small bag of 104M caps so I'll use those. The diode in the picture i pulled from a cd burner and won't be powering, I just put it in to show my complete circuit. I pulled the caps out of the breadboard and leaned...

    DIY Homemade laser diode driver

    Would it be alright to connect the 100mfd cap to the LD or does it need to be smaller. I need to go back to RS to get a perfboard to solder this all to, so I can pick up another cap then. The reason I added the small cap was because I read earlier that the larger electrolytic couldn't absorb...

    DIY Homemade laser diode driver

    I went ahead and build the circuit on a breadboard. I guess I don't have any spare protoboards so I'll have to run back to RS. The two small ceramic caps I used were from a grab bag I have, most of them don't even follow the normal labeling, but eventually I found some labeled 101J, so 10 pf...

    16gb flash drive - corsair

    Even corsair doesn't recommend using those for backups, they can go out at any time.

    DIY Homemade laser diode driver

    I left the switch out of the schematic. Those things that I added to Vout are the Rheostat and R1 to the best of my trackpad drawing ability. I must have read something in the past 45 pages wrong, but I was under the impression that because the resistance is set, and I'm adjusting the output...
