^^ agreed, you will thank chipdouglas later when you still have your vision and know how to safely operate a laser this powerful... these are not toys. stuart :)

those are dome fantastic pictures, epecially 4, 5 and 7! +1 stuart :)

3. Power density is the amount of power (time rate of energy transfer) distributed over a given unit area perpendicular to the direction of travel. Power density is expressed in watts per square meter (W/m² ) or milliwatts per square centimeter (mW/cm²). Correct me if im wrong. stuart :)

why not just buy a higher powered laser (100/200mW) rather than combining lots of 5mW lasers presumably into one and you'd have to buy lots of PBS cubes to combine all of them... pointless to be honest. stuart :)

yes you are right, the lower end of the electro-magnetic spectrum has more photons meaning better burning capabilities, but because of the gap in power (~1W) the wavelength wouldn't really be taken into consideration... the 2W IR laser would still burn better than 1W of 445. stuart :)

yeah but, you will buy & build so many lasers... and with time you will want a whole range of colours including blue/yellow which are very expensive for a decent number of mW's. BTW: welcome to the forum :wave: stuart :)

yeah i knew about that but as its not at all likely, i didnt bother mentioning it :p stuart :)

errm? 'Operating Current: < 600mA' WRONG ANSWER! :P stuart :)

blood? stuart :)

if we lose or draw on wednesday against slovenia... we're out of the cup, but lets hope for the best! :) stuart

SAME!!! :crackup: stuart :)

yeah i agree, morgan is a fantastic chap, hes always helped me and transactions with him have always gone smoothly! stuart :)

sweet video styro!, cant wait till' i get mine! stuart :)

welcome to the forum! as its been said above, you need a heatsink to run that thing longer that 30 seconds, sharp looking build! stuart :)

GOAAAAAAAAAAAAAAALASOOOO!!! :P stuart :)

:crackup: stuart :)

lol its 11:23am here in the UK, what time is it in Australia? stuart :)

lol i seen this on facebook yesterday 'Were going to win the world cup LOL JK We are England and we cant even beat Algeria' :crackup: stuart :)

how can we draw with algeria?! we should have won tonight :( stuart

uruguay 3, south africa 0 stuart :)
