That reminds me of this 1 I just saw recently. Let a = x a+a = a+x (add a to both sides) 2a = a+x (a+a=2a) 2a-2x = a+x-2x (subtract 2x from both sides) 2(a-x) = a+x-2x (2a-2x = 2(a=x)) 2(a-x) = a-x (x-2x = -x) 2 = 1 (divide both sides by a-x)

Heres another link that goes into more detail, it looks like IR in this one http://au.youtube.com/watch?v=wFDjiWwDdhE

I've always wondered how they made these, the other day I thought it would have something to do with lasers, I just found this video http://www.livevideo.com/video/7AC708782C5949008A44264D5FE5E3E1/3d-laser-engraving.aspx Wonder how strong the green is to do that :D

Try see how well you can solder with it, and if it can burn something glassy/plasticky like arcylic, perspex etc.. :P

I didn't realise Adobe bought out Macromedia, I been looking for new dreamweaver and flash MX for ages and they are in these new packages ;D These collections have heaps of great programs :)

Photoshop CS4 is on isohunt as well, incase you don't want the whole suite, plus its CS4. I'm getting that CS3 collection wannaburn linked, thx ;) Theres even these 2 links for CS4 collection http://isohunt.com/torrent_details/52079675/cs4?tab=summary and...

Heres photoshop CS2 from mininova Haven't seen a good download for CS3 or CS4 yet :(

I don't have any of them but I like the look of number 2 the best

Found it! Twas 5 pages back in the experiments sections.

I've never gotten a preset driver from Dr Lava but I don't think I've seen anyone complain about them being set wrong. The dummy load for a BR is 6 IN4001 diodes and a 1ohm resistor. You set your multimeter to read voltage(v) and you should read a voltage drop across the resistor, that is the...

Jayrob's Icebox maybe? My internet is capped so I can't find it atm, but go to tutorials>compiled list of tutorials and it should be in there, step by step how to make it, it has fans, TEC's, heatsinks in a metal box. Edit: found a sticky...

If i understand correctly, mAh capacity should only effect the lifetime of the batteries. What circuit are you using?

A few steering wheels do 900 degrees but unfortunately IIRC only the G25 has a clutch. I don't really drive, and from what my friend tells me who drives a Honda, this gearshift and everything on the G25 is a little bit soft. He gets in his car after using the G25 and crunches and misses all his...

Awesome pics, awesome looking build, can imagine alot of time and effort went into that and it looks great  ;) I keep putting these pics up as wallpapers  8-)

Hopefully you don't have one of these ;D, but seriously I have no idea what it is.

I've got a G25 and IMO it's the best steering wheel combo you can ever get, clutch, paddle and sequential gears and I believe the only steering wheel with a H-shift, realistic feeling pedals, 900 degree steering wheel. It's just awesome for driving simulators. These  are all steering wheels...

Glass AR lens will reduce the power of the beam by reflecting more light back onto the diode, damaging it in the long run. I think it's best to stick with the plastic for now. I've noticed a cloudy/bubbly effect too in some plastic lenses, I've always just assumed the lens is slowly being...

Just regarding the green module polarity, normally green modules are case positive and spring negative. That is the polarity of that module. www.o-like.com/b2b_cpinfo.asp?id=909

I've done this with a DX red module, works fine, I think there were 4 wires in the cable and I took the red and black for positive and negative respectively. The 5V from the USB should be just enough for a rkctsr red laser build.
