Has anyone ordered one of these yet now that the price has come down?

635nm 500mw red leaser diode $109.99

Seems like everyone was so in to the 300mw version that nobody really noticed this one was out again.

Hmm... I'm really liking the fact that they give you info for pulse mode. I might set something up to try this. 50Hz at 33% Duty cycle seems well within the realm of an Arduino. We might just have a 1W hand held red!

I like the fact that it's showing that "underpowering" it a 500mA and 1.9V can reduce the wavelength down to 632nm, which having a lower mW/mA ratio, could actually mean it could look brighter than higher powers.

Urm... Why arduino? A simple 555 in PWM setup would be cheaper, and even possible to stuff in a handheld.

Yeah the link isn't working anymore maybe they are sold out because it doesn't come up on their site anymore.

Hopefully they didn't have limited quantities :cryyy:

Well, rayfoss also pulled theirs after they were up for a brief time.... maybe o-like discovered the same problem:undecided:

Really can't wait to see 1W of red in a handheld though:eg:

Im not holding my breath to see if these diodes get sent out or not, place your bets anyone?

Mainly cause I have never worked with a 555, but I'll be willing to give it a go.

you can get the Arduino SMD chip which is tiny and put it on a driver board... that was my idea. But I think its about time I use my 555 sitting here.

I just got an email from Susie from O-Like and she said they will be back in stock in 1 to 2 weeks.
