Are these Mini 9LED Flashlights the Same?

[daawood123]

hmm, well i found a driver on which the led's were directly attached to, and i know it goes through the host body, but where would i attach my black wire, cause i have a multimeter and if i touch the red pin to the postive bit on the battery holder and touch the black pin to the case there is no reading on the multimeter, iv tried lots of different places on the case but still no result

That is not a driver, it is just a round PCB. The LEDs are connected in a series/parallel configuration on the PCB so they can be driven by the 3 AAA batteries (in series at 4.5V).

Scratch the inside of the tube (where you removed the LEDs and the clear plastic lense) to the bare metal (you have to scratch through the anodization, until you see silver). One probe to the scratched place, the other to the battery pack connection. If you don't get a reading, punch the clickey switch on the bottom of the tube and try again.

To use this as a host, you need to build an insulated pill to connect to the battery connector (and a heatsink that will snug fit into the tube). Wire the pill connection to the driver B+ input (you need a driver with a common ground, Driver B- common to driver LD-). Sand away the annodization from the inside top of the tube, so that your heatsink will make electrical connection to the tube. connect the driver LD+ to the plus pin of the Laser diode, and the driver LD- to the Laser Diode negative pin (AND the case pin, if you are using a blue Laser diode). This will not work for IR diodes, as they are case positive, but, if you are foolish enough to want to use an IR diode, you should be able to figure out what changes would need to be made (it ain't very complicated...)

im pretty new to diy lasers, this is my first build, i understand the scrathing bit, thanks, i will try that but i dont get what a pill is and the wiring stuff i need to do, im planning on using a ghostdrive and a lpc-826 in a aixiz module, where can i get a custom heatsink to fit inside this. also, should i just solder a black wire from a scratched place onto the driver - and a red wire from the postive contact point to the + on the driver, then attach the diode leads to the driver and done? also where did the PCB get the negative current from, there is a thin ring of metal which is not flat against the body, but potruding outwards if you know what i mean, but i have tried the probes to the ring thing and the + on the battery holder but no reading, ill try the scratching method, hope it works.
thanks for your help 123splat

EDIT: anyone know which drivers would be good to use in this build?

ok so i scratched the top part with 60grit sandpaper, and touched the probes to the points, nothing, clicked the tail clicky, still nothing, and i cant really tell if its scratched through or not cuase the host is silver, might go out tomorow and buy it in a blue version or something.
