I want to synchronize an analog audio signal with a laser and this where I came to the problem that I would know how to synchronize it via PWM by amplifying the signal and then use a simple comparator and oscillator to generate my PWM signal which I would use to modulate some standard linear...
Hey Guys,
I'm searching for a cheap (200-550 euro) Canon DLSR.
I've got a lot of equipment for a analog old Canon: canon AF mount objectives, bags and stuff.
So I want to stay with canon to keep the AF mount.
Size and weight is not so important for me so care more that its a full format sensor...
For a scientific project I want to scan a large cone shaped beam.
To reach a single point with high power density that can be moved fast.
My problem is that the galvo mirrors in my price range have to be very small because of the scanning speed they work at and I can't expand the beam behind...
I would like to know whether you think it's possible to ionize metal vapors(or maybe even gases) in a Na vapor lamp for example with a low powered aka handheld laser.
I know you can't do that with gases but their ionization energy is more than twice as high as those you need for alkali metals...

This is my first review of a laser I build and there's quite a long story behind it
28/9/13 lazeerer the man send the package with all the nice parts including a free x-lens :)

LPF OPEN SOURCE 3D PRINTER
I recently thought about building a 3D Printer especially DLP 3D printers.
Now our 445nm diodes are all from DLP projectors with relatively high resolutions and after those diodes are extracted the empty cases with powersupply, optics and DLP chip are worth a few...
It seems Nichia not only has brought us a new 1W 520nm, but also a new 9mm 445nm diode :wave:
It's rated at 3.5W typical output power at 2.3A with a maximum current of 3A
to put that in comparison the 9mm we use atm is rated at 1.6W at 1.2A and 1.7A maximum current
MORE THAN TWICE THE RATED...
Edit: I was corrected (thank you guys :))
Buy them at illuminationsupply and support the lpf member Cssihh they cost the same on his site maybe even less if you pm him for discount and you don't have to wait as long as on massdrop
