Re: Unknown Surface Mount Component
if something goes awry you risk the 18650 turning the light into a pipebomb - no thanks.
conductivity would need to be pretty miraculous too - your pushing 1-3A through it and dont want any volt-drop.

Re: Unknown Surface Mount Component
I'm not sure how strong the conductive PLA is, since it is doped with metallic particles, I would assume it's stronger than standard PLA ... ABS is stronger yet, but I don't print with ABS cause its a pain in the ass. :-)Leave a comment:

Re: Unknown Surface Mount Component
still probably not strong enough to have an 18650 rammed into it for years.
i think the simple answer is to strip all the parts off the 20mm board and fit the 17mm one against it.
i'll try it when i get a couple.Leave a comment:

Re: Unknown Surface Mount Component
wont work, it has to be electrically conductive to carry the negative rail.
it also has to support the spring pressure against the battery.
i also doubt it's a good idea to use anything that softens if it gets hot!!
a machined aluminium ring may work, i was just going to mount the 17mm board against the 20mm one.Leave a comment:

Re: Unknown Surface Mount Component
the higher end drivers have programable modes.
options for current <<< select the right board!

Please post your solution when you find one for this problem because I have the same problemLeave a comment:

Re: Unknown Surface Mount Component
exacty, however - there are times when too much brightness is a problem.
that's why i'm looking at the newer drivers that can do 5%, 30%, 50%, 100% or other combinations.
the "epilepsy"strobe & SOS modes dont interest me.
what pisses me off is all the cheap lights use 20mm boards, but all the interesting drivers are 17mm.
By the way ... my order was a whopping $3.60 ... I ordered some more LEDs too ... I have no idea how they turn a profit... and strobe modes on a flashlight .... they've had them on flashlights since before I was born and in all my 48 years I have never once heard anyone say "Boy that ended up being a handy feature..." I wonder how many unnecessary clicks that feature has forced on innocent push buttons since the beginning and I wonder how that would equate to MTBF wear and tear to the point of failure ... in other words ... I wonder just how many meaningless pushbutton deaths we can attribute to that worthless annoying feature.Leave a comment:

Re: Unknown Surface Mount Component
why 100 of them???
also, i was trying to keep cost to the minimum so as not to have it reach the cost of a new light!!Leave a comment:

Re: Unknown Surface Mount Component
another option is to fit this to your existing board.

Re: Unknown Surface Mount Component
<sarcasm> Thanks for turning me on to aliexpress.com ... BUDDY! </sarcasm> I think I wasted about 6 hours yesterday throwing crap in my cart that I knew I would never buy but I wanted a list to narrow down ... those prices are almost too good to be true - although I realize they make up for it in long shipping times ... and being on the site is like watching old re-runs of CHIPS ... just so ... klunky and old school in the layout. But addicting none-the-less ...Leave a comment:
