I voted for the 505nm since it's pretty uncommon, but I'd like to see how the Nano host holds up too.

Quite like the C3 Series I got from you but the Sanwu Pocket is still my favorite form factor.

Re: Giveaway!! Ends Monday!! Mohgasm.com Count me in :)

Due to a slight mixup in glow pigments from my supplier, glow paints are temporarily out of stock. If you received any paint that subsequently dried out while in the bottle, let me know and I'll be sending replacements once I get the correct pigments in. At the moment, I wont be re-ordering...

While that video covers much more about how the driver works than the laser, Mike's channel is definitely awesome. Highly recommend anyone who's even slightly interested in electronics subscribe :) Also worth checking out: Electronics Engineering Video Blog - YouTube

Re: Introducing 405nm.com: breathe new life into your laser pointer Yeah the red can't get much redder (which is unfortunate, a deep ~680nm red would be awesome) without going to zinc sulfide powders which don't glow long and also smell bad :p It's certainly redder than orange glow powder...

Re: Introducing 405nm.com: breathe new life into your laser pointer That picture needs more darkness :evil:

This looks very cool but why does it seem like the laser is a small [] shape instead of a dot? I think I'm going to have to try to replicate this now with my projector and RGB color instead of just green :P

The wavelength charts are the emission wavelengths of the glow, the glow powders can all be charged with anything between 300-500nm though it varies slightly by color. 400 is more or less the optimal wavelength to use, and 445nm works very well. The peak of the chart corresponds to what color...

If safety is important to you, you should probably consider just picking a laser that has a lock from the get-go. Transplanting the parts seems like it would be a waste of time/money when there are models that come with it already, as well as the option to build one with your own driver/diode...

It's a bittersweet relationship, everyone uses paypal so you need it to stay competitive and at the same time their arbitration and account closure policies are deplorable. I had my share of problems with them as well :(

If they close your account, they mail you a check for the balance.

Clarity in my opinion is the biggest factor, light needs to get in and out for it to work so you should try to find one that's nice and clear. Home depot sells "15 minute" 2 part epoxy in syringes which works pretty well and it's extraordinarily durable.

At the moment I ran into a problem with the formula for violet paint, I'm going to have to do additional testing to make a new formula for it. I'll post another update if I get the problem solved.

Re: Introducing 405nm.com: breathe new life into your laser pointer Yes exactly, only without being horribly over priced.

Cyan paint is now in stock :)

Re: Introducing 405nm.com: breathe new life into your laser pointer The ferrofluid is based on a very low viscosity oil, it wets just about anything like crazy. I was thinking about looking into those super-hydrophobic/oleophobic coatings. In other news, cyan paint is now in stock again.
