I mixed them, how can i know wich is acrylic and wich is glass? :huh:

Can the aluminuim be shortcutting my electronical components? Maybe the terminals have some insulation?

I have made holes on the other side of the box!! That photos were before i finished the contruction!

One more thing, i'll also put a capacitor in paralel with the diode, wich one should i use? Like, 10 uF is enough? Wich voltage?

Ei! Vi no profile do leo que você faz desconto para brasileiros! Você declara menos de $50 na postagem né?! Qual é o teu site!? Abraços ;) Estou pensando em comprar umzinho

Well, i understand series and paralel!! Later when i get home i'll take more pictures! thanks, again. Leo: Sim, eu quero uns 620mA num diodo c@s!0 A140 para ter mais tempo de vida e ligar num ciclo de operação maior!

I'm not home right now so i can't post the pics, anyways, im measuring in the resistor terminals of the testload. Is that schematic right? Thanks for the interest in helping me ;)

Well, that the problem, my multimeter shows 0 on the testload and i can only see voltage before my driver, the schematic is over there. The heatsink is probably shortcutting, today i'll buy something insulating for that

Allright, i did it on autocad so it may look complicated to understand...

Sim, entendo que não é difícil, eu sei desenvolver páginas em HTML e PHP, administrar fórums etc... Só não sei se vai ter procura, dá uma olhada no meu website Botequim Ciências - Ciência papo de bar, divertida... meu email é luccax@hotmail.it

Well, actually i gave up of IR lasers, i'm a begginer and i'm starting building all kinds of other lasers... An IR eye safewear is about $200...

Check this, i'll use a cooler over it: http://laserpointerforums.com/f67/need-help-i-dont-know-whats-wrong-my-lm317-58804.html I'd also appreciate if you can find out why it doesn't works

Well, these days i bought a heatsink a man made for me on a lathe, payed around $30, i tought i was doing a good deal... Yesterday i was on a electronic components store and my friend saw some aluminum heatsinks, they were a little small for aixiz modules but i bought 20 to test, each one for...

Rapaz, sou do rio, consegui dissipadores de alumínio melhores do que eu postei, aguarda um minuto que vou postar aqui as fotos!

Well, i built this LM317 today but when i test it with my own test load i fail, the current is allways 0. I'm sure there is current trought arriving to the LM317 (tested with multimeter). What may be wrong? Can you please check if i connected it right? Is my LM317 broken? How can i check if...

Allright, no problem at all...

Do you have a tracking code? Because first-class usually gives an useless tracking code that updates sometimes, anyways... no problem if you don't =)

American_Lasers is a fraud, just wasted $20, 8 days passed, 6 emails and nothing...

actually i've seen cheaper prices but i bought this because of the qualifications.. Anyways, i'm not even interested in an IR diode, i was only going to press into a module and keep it waiting until i have proper eye protection. The problem is, now i feel i can't trust ebay sellers even if they...
