The woman that said no has to be a pure asshole. You have the RIGHT to open it BEFORE you pay ANYTHING. Well, thats in Spain... but it's probably the same thing in all the UE countries.

Well done. Hopefully I'll finish mine soon.

LOL, yeah.... I hadn't seen fog as dense as this in years..... this is epic, you can even see very well a 100mW PHR.... epic

YEAHHHHHHH FUCK YEAH I USED LM317 @500mA OMGGGGG LOOK AT THIS I know I shouldn't drive LDs without driver... but hell, I was too excited, lolz.

OMG i don't have a driver yet but today there is a frekin FOG you jujst can't imagine it. I NEED to see the 445nm beam in this. Can I direct driver the xj diodes with only a resistor and a 18650? or is it too dangerous? i promise beamshots! Thanks

Thats one great host! Well done.

They cost less than $0.50.

7805 can give 1.5A

Use a 7805 regulator:

I don't think that will help. If you see lava's design (BTW Lava, we are NOT trying to copy you. We just want to callenge ourselves making good drivers.) the capacitor is in series with the amp.

So, they are useless for me, dangerous as they are IR, and I just dont want them. So why not to give them free? If you don't live out of EU I will not charge anything for the shipping. For the US maybe... $2? :crackup: I have 3 of them. I think both of them work just fine. I think you can push...

Anything above 4.7uF will work just fine.

omg..... I'd love to see the same thing that happened to 445nm diodes with green diodes!

Lolz omg! Great photos! +1! Be careful with that, it's dangerous even with goggles.

Re: My holiday project :D I can help you with the code man, don't buy something you can make yourself for way less money!

Li-Ion obviously.

I lost one of my dogs a month ago. He was 16 I think. I loved him so much but I didn't even cried when I found him dead. Why? Can I give him life again? No, so it's not worth crying, being sad or whatever. The same thing happened when I lost my grandmother. I'm not trying to argue with you, I...

Come on man, nobody (including pets) is going to live forever! Do your life as best as you can and don't ruin your life thinking like that.

I have measured an OLD (maybe 12 years old) SONY Energetic #18650 extracted from a Laptob battery. 3.85 V1 (It's not fully charged.) 3.65 V2 4.45 R 243 mOhms I don't think this is bad for being THAT old.

Any BJT will work fine. But if is a direct 5V TTL input you can conect the arduino directly to the TTL input. Maybe you should put a resistor, but I'm not sure, that depends on the driver.
