How long after planting did it take those seeds to sprout? I haven't tried growing serrano peppers but the heirloom peppers I have tried I needed to regulate the temp to 70F+ for them to sprout quickly. Reminded me of your experimenting style. https://www.youtube.com/watch?v=UM-wKQqBBnY Lol...

So is this just for funsies? It's my understanding that plants benefit from several wavelengths in the blue and red parts of the spectrum, favoring either blue or red whether they are in a vegetative, flowering, or fruiting stage.

So what kind of Bourbon does an ozone making Liverpool-ian drink?

I'm glad you asked, I have the power supply directly connected to the LED's and it turns out that they aren't getting nearly as much current as I had initially thought, only .25A, and ty very much for that diagram. Edit: Also if you'd be willing to test these LED's, I'd gladly send you what I...

How well does this balance the current? That makes sense now, I already had an problem with the "mains device" issue. While testing the light about 6 hours in a couple circuits were shorting out and I fixed the issue by increasing the silicone pad thickness the drivers are on. Can I get a...

Now that we're only about a month away from starting sprouts indoors for our garden this year I built a grow light to see if I could give our sprouts a head start since sunlight near the windows only goes so far. The already made grow lights I've seen are either stupid expensive or are from a...

With the market not demanding them I think we might be waiting forever for 405's as tough as 445's :/ I'm more hoping for <405nm diodes to hit hobbyist prices.

Definitely a squirrel, and definitely not the kind of pic I want to see in this thread.

Re: NDB7675 1.9w 470nm Pen laser made by Alien Laser :D Dang I thought my 1W pen was awesome, this tops that and looks great. I really like the lasers that fit huge power in tiny spaces :beer:

Thanks RB :beer: You may like this one too if you haven't seen it already. Melting lead

Wood glue? You'll need to solder the diode/driver connections.

Yes...

Depends on where you find your moral bedrock, the statement can easily be reversed. "I just simply don't understand why so many people focus on helping one another instead of money?" Correct me if I'm wrong but these probablies are totally made up. IMO if there is ET life out there capable...

Lol, na it's fine.

Thermal selfie! - Seek had a black Friday deal.

My first NUBM44 6W+ build. Powerful enough to melt a lead pellet gun pellet.

The aluminum video was pretty neat but I don't believe the laser is actually "pushing" the foil. I would guess temperature changes in the foil are causing the displacements. If these lasers could generate that level of force a Crookes radiometer would spin in a strong vacuum but they don't...

I'm not buying the "look away" solution either. I don't know how that stands legally but from a realistic perspective here, that doesn't make sense. How could he know when it's safe if he doesn't look. It the kid was being malicious should tuskiomi really be expected to take a shot in the eye...

I just got this host in the mail and my jaw hit the floor. A#1 host. I should have the doide tomorrow to complete the build.
