Info for all:yh: NASA's Next Mars Rover to Zap Rocks With Laser - NASA Jet Propulsion Laboratory Rod

Anyone know of any lower power/cheap (newwish grade):) <100mw 445nm lasers available or coming down the pike? Sorry if it's been asked already but I couldn't find anything listed in a search or two. I did find this on Epray but the price is "way too high" for the power. If I was gonna pay that...

OK...I admit that I'm addicted to watching the TV show called "House" Flame away!:na: Anyway...tonights show had House shining a green laser at one of the doctors. And not just at the body. He traced a circle around the doctors eye face on. The first thing I thought of was :wtf:....one slip...

Anyone ever play around with a door peephole? What sort of useful optics are inside? A bunch of Google/forum searches and I came up with nothing about the actual optics that are used. Interesting enough...some of the peepholes are the same diameter as an Aixiz module. (12mm) I'm sure most of...

OK, Do you have any electronics or laser related mnemonics that you remember from school? The only 2 I can recall off the top of my head are.... Bad Boys Rape Our Young Girls But Violet Gives Willingly. Get Some Now! Resistor color code. ELI the ICE man voltage(E) leads current(I) in an...

Just an FYI...... Halloween is coming up soon and the stores will be stocking up on fog machines if anyone is looking for one. You can usually get one after halloween for about 10-15USD I'm sure the vets know this so this is just a reminder to any other noobs like me:) I have several around...

Here's an idea I've been thinking about for a host. It's probably considered "outside the box" and a hell of a lot of work! Start with an outside threaded tube with an inside diameter large enough to slip an Aixiz module and whatever battery you want to use into. Take about 4-5 silver dollars...

Hey folks, I've been mulling this over in my head for a few days (as well as searching) and can't quite figure it out..... Lets say you have an un-IR-filtered 532nm laser that measures 200mw on an LPM. You install an IR filter and then it measures 150mw. Without knowing the efficiency of a...

Is anyone familiar with this unit? Primarily can the power output be decreased easily? I'm thinking of a christmas decoration idea but the duty cycle is only 2 hrs. I'm hopeing turning the power down considerably can extend that to continuous operation. Also is the pattern a starburst or some...

I was outside playing with my star-cap 532nm greenie last night. I pointed it at the only tree in my yard and thought it would make a neat Christmas light display. Kind of like putting Christmas lights in the tree but with lasers:) All it would take is a small, slow speed motor, to rotate the...

Just an FYI if you only need a part or two for your next project. Moyer is an electronics parts retailer with a no-minimum policy that I have used on many occasions in the past. They will ship 1 resistor in an envelope if that's all you need:), and don't gouge on the shipping to make up the...

Just an FYI.... There's a show coming on at 8PM here on G4 TV that will have a segment about homemade lasers. It's channel 162 here in Virginia, USA on Comcast, but I'm sure your mileage may vary:)

A plane made an emergency landing on US-23 about mile from my house. Glad I wasen't outside playing with my lasers. At least no one was injured and even the plane survived:) Cudos to the pilot!!

This is ridiculous! 3 hours of sleep in the last 72hrs. That's even with taking Ambian AND Xanax before bed. Got a BAD cough and it keeps me from getting any sleep. Somebody please come shoot me in the head with a 5 Megawatt laser. I'm so freaking loopy right now from lack of sleep. It took me...

Hey all, If anyone is considering an upgrade to their Laserbee power meter, and wants to sell their HLPM model, please let me know. Edit.... I just ordered a new one from Laserbee/Jerry. So...Disregard:) Oh wow, I just noticed.... I now have 2 rep points!! Hoorah!!:takeit: Thanks, Rod

OK...I'm probably missing something fundamental here, but could someone explain to me why an IR heater such as.... Link-Quartz Infrared Heaters is not dangerous, when an IR beam from a laser is? I know the IR from the laser is collimated and fucused but why is a space heater, designed to...

Hi everone, I thought some might be interested in this... Microscope It's a USB microscope that can be outfitted with filters for specific wavelengths. 630 nm 690nm, >-= 91% 665 nm 730nm, >= 91% 715 nm 780 nm, >= 99% 780 nm 830 nm, >= 99% 830 nm 900 nm, >= 99% 850 nm 1100 nm, >= 99%...

Hi all, Well, the title says it all. I'm looking for a few CHEAP laser pointers/diodes for a learning experience. They can be completely dead or burned out. I just need them to be "complete" and not been hit with a hammer or other..:D I want to disect a few to see whats inside. I'm still like a...

Hi, I have been reading for a few days and thought I would introduce myself in case I started making a few posts. You have a Great forum here. LOTS of useful, interesting information. My name is Rod, and I have been an electronics tech for 30+ years. I never really got into lasers but wish I...
