Hi,
I FINALLY got my parts from the US and spent the afternoon putting them in a 2x AAA mini mag copy - as good as though.
My "circuit" is a 16V 47uF Electrolytic Capacitor piggybacked onto the LD, and a current resistor (10 ohm) from the 2x 1.5V AAA batteries. Very neatly packed into the torch. I measured twice and cut once'd on everything - so not to blow my presicous LD.
I get about 240mA on fresh bats, and about 160mA on an old set. It's bloddy bright - I think I might be investing in some goggles very quickly, as I like my eyes as they are.
It just won't pop/burn/etch/light/melt ANYTHING!
I even went to our local balloon shop and bought a bag of black balloons to try - nothing! I left it there for about 60 seconds, and it won't burst. It just sits there being balloonish.
I did get a tiny puff of smoke from a match - but alas, it did not light.
I must be underpowering this LD, but I've followed the reccomended specs for basically everything - bar the torch itself - but that's just a fancy case.
Being in the UK, I don't really want a $17 LED, and the fact of ordering more taking about 4 weeks. The last GB one took the best part of 3 weeks.
Also, for this kind of work - DVD drive lasers etc. - what are the best goggles - I know there is a search button, and I have looked, but I get confused with all the , 3-5 transparency etc. Could someone definitvly say what I should be looking for, where I can buy them from the UK, or US, and if from the US, could I paysome for them and they send them to me via themselves if the company doesn't post out to the UK!
Lastly, what kind of duty cycle is best? I've heard 60/60 works well. Can anyone advise better?
Nothing gets hot in the case.....
Ta!
