I want to build a 3W - 3.5W blue with G8 lens. I see several 9mm diodes (NDB7A75, NUBM06, NUBM08, etc.) on the DTR site which will run in the 3W range. Some 9mm diodes have a G-ball lens. I assume the G8 is better so I will need to remove the G-ball to put in the G8. I don't know if this...

Hi Rich, Firstly, So sorry to hear you are not feeling well. I hope you get better soon and are back to good health! Those Mag heatsinks look very well made! So I am building a 2 x 21700 - powered 3 x C-cell Mag. 1) Are the heatsinks for Mag D and Mag C the same? I assume so since they use...

hello Rich, PM sent. Thanks.

ok, thank you.

One more question: What about circuit 'noise'? I assume that as long as no overshoot is involved in that 'noise', circuit 'noise' in the driver doesn't adversely affect laser diode life either? Why do driver designers tend to mention 'low noise' as a positive design aspect in their drivers?

Question: 1) The picture shows 2 chips being heat sinked to the main bottom copper sink. Do both ICs get hot? I thought the only IC which needed to be heat sinked was the black chip (with the many legs coming out the sides)? 2) In the picture, the smaller chip on the left is the one that...

Thank you for the info on the battery monitor. Just to clarify, does this build have a monitor in it? I wasn't sure if it was a new build without a monitor or you modified an older jayrob build which already had his monitor. In general, if you were to put one in your build, I assume it would...

Hello, Very nice build! 1) Can you show how you built the monitor and LED? 2) Can you re-link the monitor link? It doesn't work. 3) Connectors are good for changing diodes but are there any disadvantages to using connectors rather than direct solder connections? Thank you.

I've been looking at various safety disconnect features we sometimes see at the tailcap of a host - usually in the form of key locks or power connectors like the 5.5mm/2.1mm male to female connectors often used on power supplies for various small appliances. When the male connector is pulled...

You have quite a collection of modules. Thank you for the photos!

FYI, AUG_DTR said all modules are 1.0 to 1.5mm longer (total length of both halves screwed together) with diode installed. This would imply the 35mm diameter module is 29mm long total length WITHOUT the diode installed because it is 30.5mm long WITH the diode installed. This, in turn, would...

Thank you to everyone here for your input. Always appreciated!

ok, thank you for the advice.

So without the sleeve, closing the jaws of the vice slowly may still cause the plunger or diode to get cocked sideways.
