i just wanted to ask if i used a cr2 3v rechargeable batt. to power a laser, would the initial voltage be 3.6v and with a 3.6v battery, would this voltage be 4.2v and if so how long does it stay there till as i heard that its supposed to drop reapidly to its normal voltage except a cap and a...

simply which green dx laser is better this cr2 one or the aaa true 30mw one i quite like the cr2 one coz it can be taken apart and the batts should last longer http://www.dealextreme.com/details.dx/sku.7883 http://www.dealextreme.com/details.dx/sku.469

Well i think the dorcy mini take one cr123 doesnt it?? anyways if it does then rather than spending $20+ on it get this http://www.dealextreme.com/details.dx/sku.5977 its very tiny but i think the head should be big enough :)

SOLD for sale is the block/ bracket whatever you may want to call it from a new liteon 20x dvd writer. i removed it using anti static protection and put it in an anti static bag right away. It has the 20x laser powerful laser with the infrared laser and all mirrors and lens etc inside The...

well i took out a 18x open can laser diode from a liteon dvd rewriter, put it in a mini axiz housing with a board at the back and a wire. lights up well, tried it with a pot in series with 3v. 30ohms by the way. oh yeah the laser module doesnt have the lens im afraid, so you'll just have to put...

so i killed my 6th 20x diode, long story made short the original ribbon was soldered to a wire and then glue with the aixiz cover on. i removed the glue (glue from glue gun sticks) and twisted the aixiz housing to take it off so i could solder the wire back to the ribbon as it came off and the...

hi does anyone have a spare aixiz lens for the housing which they could sell to me for a small charge or if im lucky for free :P i tried to make the hold bigger and then lens got messed up so i need it quick. thanks

got my housing today and i wanted to know if someone could share the link with me that shows how to make the hole for the lens bigger to allow more laser to get through, i cant seem to find it many thanks

im going to use 2 cr123's so i will have 6v. 1 laser diode 1 lm317 and 1 capacitor so would it be alright if i just use these and will they give me the right voltage? If the lm317 is used as a current regulator, then will i always have that amount of current until the batteries dies out...

my fifth dvd rewriter 18x and 20x diode has just died 1st diode- Over powered and then pins broken off 2nd Diode- pins got twisted and i touched the mirrors with a wire and it lighted up woot. But was connected directly to batts so it died 3rd diode- died coz it was directly connected to...

hi i made my homemade laser and want to change the power supply to two cr123a batteries that would be 6Volts because they will be rechargables i will use a pot to reduce the current but if i want the voltage to be at around say 3 volts, would just using the pot work SO it would be 6V-3=3...
