Apparently a new record in data transmission. Using a single laser to send data in multiple wavelengths. I didn't quite get how they did that, but it's cool nonetheless. BBC News - Laser puts record data rate through fibre

Hello there, here is my spirograph V2. -3 motors, a poti each and two of them have reversible direction -fixed green with LM1117 driver -runs off a single LiIon It looks like frickin mess, but I kinda do like it. Hope I didn't bore you guys too much.:na: OK, so here's a video, trying to catch...

:eek: You might want to pass on the very graphic picture if you are susceptible to these kinds of things. I wonder if he will be OK.:undecided: http://i55.tinypic.com/2h30eue.jpg

Not entirely laser-related, but cool enough for the science section: Almost a century ago, Einstein thought up the theory how mass distorts the space-time continuum. Not only does it bend it, but apparently the earth's rotation twists space-time as well, like a spoon in a jar of honey. Only...

Hey folks! "Water, fire, air and dirt $%&*in' magnets, how do they work?":thinking: e1QyWydo_bk So I had this targeting laser from a 15$ BB gun that broke (the gun, not the laser) a long time ago. The laser is your crappy button cell powered, low powered red. I noticed the size and realized...

Hey guys! Do you ever play flash games in the browser? A while ago I found these by this japanese dude, and I think these games are really great. Besides being filled with tons of cute japanese animations, they are unusual. I've never seen anything like these before. They are logic based...

How bad do you need one?:D Auctioning off one unused Micro FlexDrive, V5 or V4 if I'm not mistaken. ^^^Scratch that, it's a microBOOST. It's the number 6 on these pictures. If needed, tomorrow I could solder some leads to it and hook it up to a test load, but there's no reason it shouldn't...

... can be found inside the cords of old keyboard, mice, all sorts of cables for computer accesories, USB cables for example. There's 4 strands in it, black, red, and two other colors. It's multistranded so it has adequate flexibility. No it doesn't have sillycone insulation and it doesn't have...

IT'S BEEN SOLD! or has it....?:thinking: I'm putting up for sale this pointer I made here: http://laserpointerforums.com/f42/635nm-40mw-pointer-build-61949.html Runs on a 14500, or optionally 2xAA. I don't know how many mW it has exactly, but if you focus it down with a lens it'll smoke the...

El-em-three-seventeens and low-ohm resistors, caps, diodes, switches, all sorts of transistors, parcels from china the postman me brings These are a few of my favorite things... When my LOC led's, When some jerk scams, When I feel so sad.... I simply remember my favorite things And then I don't...

This will be a collection of worthwile links, inside and outside the forum: IF YOU FEEL LIKE REPLYING TO THESE THREADS, CHECK THE DATE 1ST UNLESS YOU HAVE SOMETHING IMPORTANT TO ADD, MOST OF THEM ARE NOT EXACTLY "FRESH". Beginners corner...

So I had this lying around for many months, I tried to make it flame, but it leaked gasoline everywhere and the flame is not nice, pobably a worn out injector nozzle. So I took it apart a and scrubbed and scrubbed. What do you guys think? Two lasers? Hmmmmm..... Or one mean, big ass laser?:D...

Hi folks! Today I got some tailclicky switches from DX in the mail. Just what I needed to complete my Kryton groove 445nm build that I got basically new and unassembled from someone who liquidated his hobby.:) It had a nichia blue already pressed in its head, so I was kinda stuck with that, not...

Quick question, title says it all. I want to make another testload and I'm all out of IN4XXX's. On the other hand, I have plenty of PR1504 (and similar) diodes waiting to be pulled from PC PSUs. From the datasheet it looks like almost the same to me, maybe the voltage drop is a bit...

Hello community! I have noticed rising demands for warning labels and at the same time a sever lack of supplies of same item. 0.90$/sticker shipped worldwide, minimum order 4 stickers, otherwise add 1$ for stamps also add 5% PayPal fees OR send payment as "gift" >=5: 0.80$ each >=10: 0.70$ each...

Hello community! Today I finally put my "sayno" 635nm 40mW ebay diode into a host! I used the driver from a greenie ebay pointer, because it is a negative regulator, and these diodes are case positive, just like IR diodes. Furthermore, the diode's pinout is the same as the IR pump diode's. All I...

Hello guys. I've got here a jayrob 405-G1 lens for which I don't have a use. It's not new, but in good condition, i.e. no scratches. I'll put up a picture later. What is the man himself selling them for, almost 60$ shipped IIRC?:thinking: I'd like 45$ shipped worldwide or might consider a...

Hello dear community! I have two 635nm diodes, one rated 20mW and one 40mW. Right now I am just experimenting with them (in O-like modules) to see how much current they can safely take and still have that nice bright and visible red color. Now listen up, you λ-junkies. Here's another one to add...

Hello you guys. I've laid my mitts on some circuits here, but I don't really know what they are. I was hoping maybe some would recognize these. RED is one side. GREEN is the other side. I think no. 1 and 6 are flexdrives, but what version?:thinking: Thanks for your help.:beer:

I've been wondering and scratching my head, what the heck happened that day? Whereas is quite the sad number in comparison...
