How about boiling a glass of dark coloured liquid? i.e. coke! :D

The green 'globe' one near the bottom looks absolutely FANTASTIC!!!! Almost 3D?! I wish I could afford the parts for my scanner now... :( But good work Andy! Dan :-)

ok, I can't say for sure, but my guess is that the TNT shipment WILL require a sig. for 2 reasons: 1. It's TNT and most couriers track and 2. it cost $40, and is likely to have insurance, and they'd need to track where it went in the event of a claim. With regards to the 'laser writing' its not...

WOW! Much better! (It's just cut off a tiny bit on the red aurora) But it looks good! Dan :-)

The maplin spray stuff if quite good for a little bit of messing around. I tend to use a few quick sprays here and there and I can use my DX30mW like a itsy-bitsy light sabre, but even though the beam is more visible, you can't really see the smoke.??? :-/ But like SenKat said, it doesn't stay...

The diagram you posted before explains your own question. Look at the dichro no. 2 above the red laser. In that particular setup, the dichro is passing the green light through and reflecting the red light at 45 deg. And if you swapped the red and green lasers around, you would need a...

Cheers! I'm sure DDL will add it to the 'useful links' or something. Maybe even a sticky? But that section is really full under the General section. Dan :-)

Hi All, I know there is a mega-ton of information floating around here, and all someone has to do is SEARCH for the answer. And I know most of it is stickied into relevant threads etc. But sometimes some questions asked are about the basics of a subject. So I've come across a REALLY good...

Yeah! - Get Greg or DDL on the case in a few years!! Also, I laughed when he stated in the article "At 635nm the capacity of a DVD is 1GB" Eh??? lol  ;D

Hi, I just thought I'd share this with you all: I was reading the latest edition of "The Engineer" (UK Science Periodical) and there was an article about a new type of UV laser diodes being designed. Supposedly the "shortest wavelength ever made by a diode" or something. Anyway, I scanned in...

Well, the designs have been finalised, and all I need to do is order some plastic and get cutting. However I need to finalise the design of another (non-laser) project which I need some similar plastic for. But the postage prices are high per order, so I'm going to order combine both together...

Re: Hex DIY Red Laser - The ULTIMATE burner idea! Won't a normal lens do?

Re: Hex DIY Red Laser - The ULTIMATE burner idea! Paul, that idea is a work in progress, and about 3 hours old! I thought of putting a convex lens to straighten the beams up, or place a collimating lens instead. Yey - or neigh? :-?

Re: Hex DIY Red Laser - The ULTIMATE burner idea! OK, I've been busy and waiting on a few parts, as to test a few ideas out. PLEASE let me know your thoughts on any of these ideas, criticisms + suggestions etc. (As I've only thought them up - so theoretical!) 1.) Mechanical Focus of Individual...

Lol, some guy has it as his pic. I can't remember who - he's the man to ask! I merely have it in my "Custom Text" and have done since the day I joined! <------

I thought you'd like that! :P

...You throw your WL Core at the Left mouse button, if you want to right click....... :D ;D

That's why I posted it! The guy is making it seem like it's the best thing since sliced... bread! :D

LOL!!! http://www.instructables.com/id/Control-your-Computer...-with-a-LASER!/?ALLSTEPS I've seen this done loads before, like most know, optical mice are great fun aiming them at bright lights. He's got a nice idea, BUT how can you click!!!!! Also, guess which laser he's using - yep, it's a...

Fantastic, Fantastic, Fantastic!  ;D I don't know why I couldn't find this earlier! Thanks zarinwoop! @Senkat: I'm probably going to take the board off, as I'm planning on making a nice 1-off aluminium housing for this special one! Solid bar, the works, however I need to get it working on a...
