NOTE: When I twist the lens the big 'X' rotates along with it. This leads me to believe it is something within the lens itself...

It is a square heatsink so I will not be able to do that test: Lab style heatsink for 12mm laser modules - $20.99 : Modwerx Shop This is my first 445 and I had a heck of a time trying to get it pressed flush within the Aixiz compared to the other red LOC's I have done before. Visually, the back...

I purchased the following glass lens from here for my 445 laser in Modwerx heatsink: AR coated glass lens for 405-445nm [LENS3] - $12.99 : Modwerx Shop There is an elongated 'X' that is quite big around the beam. It is a new lens and I even cleaned it using special photo-quality swabs. Am I...

Just purchased this 5.5vdc / 7 amps (35 Watt) power supply: RS-35-5, Mean Well RS-35-5 Thanks for everyone's help - you are the BEST!

I am almost positive the 5.5 volt PSU will work, here is the documentation of the driver: http://hacylon.case.edu/laser/FlexModP3/FlexModP3_Manual.pdf "It can accept input power in the range of VDiode + 1.5V up to 24V and the output voltage will match the load requirement."

Thanks man, it's "paul AT zimmtech DOT net" I just ordered some Alimex from here so I have everything I will need: https://www.midweststeelsupply.com/store/CastAluminumPlate That includes the main 3/8" thick baseplate and also three 1.5"x1.5" (1/4" thick) supports for the Modwerx laser...

Right, I understand that the output of the driver needs to be around 4.5 volts but what about the INPUT voltage from the battery? Don't all these constant current drivers adjust the voltage based on the diodes voltage/current curve? I have tested some drivers being powered by only a 3 volt...

Thanks fmy friend, that's all I needed to know!

I cannot find any decent 6 volt (+2 amp) power supplies so I am instead thinking of using something like this: 5 VOLT AC/DC POWER SUPPLY - RS-15-5, Mean Well RS-15-5 * The output can be adjusted up to 5.5 volts. So 5.5 volts minus the 1.5 volt driver overhead is 4 volts TOTAL. QUESTION: Is 4...

Hello again, I got two of the FlexModP3 drivers in the mail today: http://hacylon.case.edu/ebay/laser_diode/FlexModP3.php One driver will be used to power a 445 diode and the other will be used to power two LOC red diodes in series (each LOC will get half the voltage). Now the FlexModP3 driver...

Hello, I am in the process of building a laser projector and I have two of these FlexModP3 drivers: http://hacylon.case.edu/ebay/laser_diode/FlexModP3.php One driver is used to power a 445 diode and the other will be used to power two LOC red diodes in series (each will get half the voltage)...

Re: FOR SALE: SpaceLas PT-20K max35k [UNUSED] The first (least expensive) step would be to build a sound card DAC to control the X/Y galvos and the intensity of the laser: Sound card DAC tutorial I just got all the components to my sound card DAC yesterday in the mail and I soldered everything...

Just got all the components to my sound card DAC today and I soldered everything together. It's coming together great so far! I used a ribbon cable from an old PC which I intend on connecting to the C-Media sound card when I get that in the mail. Tomorrow I am going up to get some 1/4" aluminum...

Re: FOR SALE: SpaceLas PT-20K max35k [UNUSED] I think Kiyoukan feel through, have not heard back from him. Someone else just sent me a PM about the galvos. Will let you know if they don't purchase. Thank you for the interest!

Re: FOR SALE: SpaceLas PT-20K max35k [UNUSED] I just now spent $218 for these PT-30K galvos: Galvo(scanning) system ILDA30K Max50k for Laser systems - eBay (item 290474375854 end time Oct-11-10 05:49:50 PDT) I really want to get rid of the PT-20K's now, they are brand new and still up for sale!

Thanks for the tip friend! This is the exact LM7905 I ordered online and it should be here this week: LM7905CT Fairchild Semiconductor Linear Regulators - Standard I will take you advice and solder pins onto the PC board. You think the part I got will work? I am not an electronics expert so any...

I just got my "LaserBoy" correction amp in the mail from Dr. Lava. A couple people requested that I scan and upload photos of the bare PC board. Here you go :) I had to scale down the attached photos to upload to LPF. The full resolution scans are on my personal website... Full resolution...

LOL - I didn't even think of that! I have several PC power supplies sitting in my "bone yard" right now. I will test which of the leads are 5 volt. Thanks for the tip :)

Correct, I purchased the exact same 150mW laser as in the OP. It already comes with a power supply but mine has an Analog input to modulate the beam. I only need 5V to turn it on, you think just straight batteries (with 10K pot) would work? I just want to test it out and don't want to damage the...
