I'm at a circuits-I level and am tired of learning non-intuitive lessons the hard way so I figured I'd ask. If just for funsies I bought a dozen of these - https://www.ebay.com/itm/1PC-Farad-Capacitor-2-7V-500F-35-60MM-Super-Capacitor-NEWCSUS/232574155576?hash=item36267ffb38:g:HXkAAOSwB09YQFTk...

I am trying to find a decently priced host to build a focusing 365nm light(diode linked below). I have and am fond of the light linked below but I'm hoping for a better host without breaking the bank...

Up is my freshly built Kryton Groove 445nm laser. Host: Kryton Groove Driver Type: Buck Diode: NDB7875 9mm 445nm Current to Diode: 1amp Lens: Single element & 3 element lenses included It's a gently driven diode that is putting out around 1.4W with a G2 lens referencing DTR's tests. It can...

Atricle -> https://www.sciencedaily.com/releases/2016/01/160121110932.htm Just wanted to share. There seems to be plenty of UFO enthusiasts here, I'm curious about the opinions/discussion on this.

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...

I'm considering doing a 6W+ NUBM44 450nm build @ 3.5A. I'm thinking about using the S4X host- S4X? Host Assembly Anyone have any experience with this host? Thanks, Duke

Has anyone played with these yet? Or found them cheaper? 5mm LED - Ultra Violet 351nm 15 Degree Viewing Angle

I'm curious if anyone else on LPF enjoys tinkering around with 3d printing and makes use of a thingiverse account? I recently participated in one of their challenges and got third - #CatchTheWind collection - Thingiverse It actually turned out to be a disappointing loss but it was still...

I'm planning to take on building a grow light, partially for the fun and mostly because I want a quality light without the quality price tag. Hydro-grow has the spectral mix I would want. 440nm blue 470nm blue 525nm green 640nm red 660nm red 740nm far-red I have no experience with grow lights...

My wife and I recently purchased an old house and we were considering getting an energy audit, the kind where they use a blower door and a thermal camera, to resolve any insulation issues that are less apparent. We actually found a company that would do it for only $100. Our issue is deciding...

FLIR ONE? personal thermal imager by FLIR® - See the Heat° I'm excited, anyone who knows more about FLIR care to weigh in?

Updated BenBoost Sale - 28 Available $100 shipped for the lot These BenBoosts still need two components, the inductor & diode, soldered on the back for them to be completed so they are being sold as is. I will provide the needed inductors but you will have to source your own diode. Or maybe...

I have a raspberry pi w/ NoIR camera and a few acessories coming in the mail tomorrow. My main project is to see if the camera is sensitive enough to IR to be rigged into a night vision scope with 808nm laser illumination, if not I have other ideas for it. Do any of you guys have experience...

I figured I'd share my recent experience flying with my laserbtb 100mw 532nm pointer(white). Last week I had to fly on a structural inspection from Chicago to Dallas and back same day. All I brought was a backpack with a few measuring devices and my pointer. The purpose of the pointer being it...

I've been unsatisfied with the cheap chargers I've had in the past, so I purchased a few chargers searching for one that I really liked. These chargers have already been technically reviewed very well, links below, my review will only be my observations and impressions of these chargers...

Not much info on the laser but thought it was neat. Traders with need for speed turn to laser beams - The Wall Street Journal - MarketWatch

I'm not looking for your speculation or assumptions, I have those. I would appreciate knowledgeable responses on this question though. "Can Diffuse reflection from a 1W 808nm Cause Eye Damage" Intuition leads me to think the two ways to damage your eyes with lasers is by causing destruction...

"Is it morally ok to be rude/disrespectful to someone who you perceive to be less intelligent than you?" I have my own beliefs, but I am simply asking this question because I am curious to see what some of the LPF communities response is, nothing more complicated than that.
