If you want to use it straight of 2xAAA batteries you shouldnt need a driver. Buy a Capacitor. Ask for a 47uF 16v Capacitor. They cost about 30 cents in Australia. For the resistor you will not need much resistance if you are using a 16x burner laser. Put a 5ohm or maybe a 3ohm resistor on it...

Dont use it without a driver. For 2xAA it will work but its not guranteed. A driver provides clean constant and sufficient power for the laser. Your best bet is to build the driver(read forums) and use a 3ohm resistor to get a nice current for the 20x open can diode. You will need at least 6...

Ive got the 70mW version i ran it on max pot off 4xAAA batts for ages its fine. I sold it off and its been 4 months and i haven't heard anything from the guy i sold it to. I bought another one of these for my self and am curious to know. If i was to attach a standard DC plug to the unit and use...

Yeh, i too think a little more information would be good. Budget wise, power, wave length.

There are 3 wires on the TTL, one with +++++ on the wire one with a --------------- on the wire and a blank wire. To where do i connect what?

Whats is it for and how do i use it? Are there any benefits?

What sets the duty cycle? Does the chip turn off when the temperature threshold is exceeded or do we just have to remember to turn it off after X amount of seconds?

The first time i played with my laser, my eyes felt tired. Then i got use to it. I have never looked into my laser, but i did drop one of them and it did shine in my eye and now i got a little spot in my left eye. Red lasers DO NOT put out ANY IR. They are purely RED lasers. Green will put out...

Put a rubber washer between the metal washer and make sure its pushed up tight. Should be if the laser module is cut to exact length. You can always just get some waterproof glue and squeeze it around the seam on where the washer sits to the body of the torch then wipe away the excess...

Whats the cheapest possible way to build either a green OR red(not both) xy scanner? Can it be done for under 100? Also how do i combine two lasers. I want to combine a green and red laser(cant afford a blue at this time :'(). What do i need for that? Is it cheap?

I dont think though that he will be able to fit the washer or what ever he is using to hold the laser module in place will provide a sufficient tight water proof seal around the top of the torch.

Is it going to be waterproof though when you install the diode? I reckon, smother the inside in silicone or something else so that water cant get on any of the vital parts, although i don't think getting water on the parts inside will damage anything unless you get water into the diode. I'm...

Woah so small. if i tried to do that there would be solder EVERYWHERE! If you were to sell how much would you charge? Will you assemble your self?

Why can i see my open can diode beam at night but when i take a picture with my camera phone, i cant see anything? How do you people get the beam to come out so well in the pictures? I'm using a Nokia N73 3.2MP Carl Zeiss lens camera to take my shots.

It wont get seized from customs, ive bought alot of lasers and ive payed like 8 dollars for postage. I live in NSW and here there is no law against me importing ANY type of laser(as long its not a medical laser).

Shipping to AU for the 30mW dx?

I'm also in AU does that mean they have to be sent to the US and the back? Amk can you pm me the company you are using because i need to get some boards printed and cant find anything local to me.

Tried to translate it from Dutch(i think thats what it is) came out as the same thing. What if this is a spambot? We got a few spambots on our gaming forum which post random stuff in non english lanugages.

What? Go home.

You need to slow down the speed of one fan to be able to get a different pattern reflection off the second mirror. I used very small motors(vibramotors) and to control their speed i used 2x100ohm pots on each motor and i can generate flowers, triangles, circles and heaps of other things.
