i dont mind that the paint chips, as i was thinking about stripping the paint and plasti-dipping it. i have no use for a case either. i was thinking that if the 5mw version of this would run from a AAA it would be cheaper to make them both the same laser, then bin them and sell the better lasers...

also, what did you think about the build of that laser? do you have any similar modules/pointers that you could test with an AAA.

yes i have, i cannot justify spending that on a 5 mw laser, but if a 30mw laser doubles as a 5 mw laser in the same package, at 20 dollars(with battery) i could justify spending that

will this pointer work with a AAA battery, and if so what would you estimate the power to be? i want to get one and if it would drop to <5-10 mw i would consider it safe enough for indoor pointing

i think i have decided on the lazerer 30mw tiny greenie.it uses a 10440 which isnt a problem for me, it's small and rather powerful. if i will be using it inside where reflections are possible i would either put in a AAA battery and see if it will power on or i will get here which should block...

i have some 18650 batteries i pulled from a useless(to me anyways) laptop battery that was pretty fresh and new, that i no-longer needed and got 76mw for the cell i tested, i figure thats pretty darn good and finally have some cells i trust in my 11 watt flashlight(kaidomain c8 xml-t6) can...

i like the idea of an american seller, i prefer to overpay to an american than anybody else, but i don't want anything over 10-15mw, i want something that wont require goggles, as diffused reflections could hit eyes, but it would be nothing direct. if the host is a standard cheapie green i am...

i want a low cost green laser for pointing, it only needs to be bright enough to be seen in a dark room or at night, which i assume to be around 5-10 mw. if it isn't please correct me and direct me to a good pointer for the cost. it would be nice if it used AA or AAA, but 18650 would be ok, as...

i may be onboard for a group buy, depending on prices. i dont have much money for it . anyways, +1.

i have been looking about the same laser, looks good to me and i think ima get it if i was you i would get the glasses, i have had many close calls with my eyes, and dont want any more. at any time in the night a 50 mw is plenty to grab attention, i had a 10 mw greenie that lasted me all of 3...

the most powerful laser i have had yet was a 10 mw greenie, but i think ima look into a 1W+ 445 to scare the living shit out of anybody who points one at me, i'll also get lots of new glasses for me and freinds.

my guess is that theoretically you could have lasers with the polarization changing in 20 degree increments, and combining them repeatedly with cubes.allowing for 68 or 9but you would need to reflect one and pass a large range of polarization angles,but everything works in theory. that would...

you can get decent 18650 cells from dealextreme, but i do not reccomend their lasers. their flashlights would make good hosts if you had a lathe to make heatsinks.

Yeah, sorry about that, I'm usually the grammar nazi Also i will only adjust the current a bit. it will have plenty of heatsinking. it should be fine i will keep an eye on the draw and never let it go over about 400 mA

i am aware of that, we are looking at "does it work or not" , not how well

a simple test to see if the battery works. requires a simple motor, or led. get two AA batteries. power either with the AA, then the lithiums. if the motor sounds faster, or the led is slightly brighter then it is not the battery. if the lithiums seem the same, it MAY be the battery...

this sounds great, im much more confident. in more detail, for those who want to know, this is my planned build. module: 30mw rayfoss greenie. will have laserlands lab style heatsink. powered by one or two 18605 batteries in parralel. you can get battery holders from digikey. i will also have a...

i am interesting in buying the rayfoss 30 mw green laser module. i have heard everything from immediate replacement to ignoring about their tech support. i personally think that they have the capability to rapidly respond to questions about a product. whenever i hear of anybody telling that they...

use a digital multimeter to test the draw of whatever you power with them. multiply the draw in miliamp hours by how long it lasts in hours, as a decimal (30 min=.5. if you need help divide the number of minutes by 60 and you have your decimal) and you will have your batteries specific capacity...

today i was interested to know if i could get some 18650 batteries cheap. i simply walked into batteries plus (any local battery store should do fine) and asked if they had any dead laptop batteries. so he turned around, picked one up from a bucket and handed it to me. then proceeded to ask what...
