Unknown Surface Mount Component

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

still probably not strong enough to have an 18650 rammed into it for years.

And the beauty of 3D printing is you can just print another one if something goes awry ... or print 10 and throw em in a drawer...

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. :-)

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.

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.

They make conductive PLA, and it only softens around 190C

Re: Unknown Surface Mount Component

what pisses me off is all the cheap lights use 20mm boards, but all the interesting drivers are 17mm.

I just whipped this up on the 3D printer in about 10 minutes ... should work as an adapter ... if you want, show m the particular 17mm board you're interested in, I'll order it and I'll make an adapter that works and if you have access to a 3D printer, ill send you the file, if not, I'll print up a bunch of them and mail them to you.

Re: Unknown Surface Mount Component

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

that's easy,
the higher end drivers have programable modes.

options for current <<< select the right board!

Re: Unknown Surface Mount Component

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.

exacty, however - there are times when too much brightness is a problem.

the "epilepsy"strobe & SOS modes dont interest me.

I had not noticed that ... sounds like a job for a 3D printer ;-)

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.

Re: Unknown Surface Mount Component

btw, i like cheap lights - gotta keep those 18650's in something!

Ive never had a light that used 18650's ... I vape with my batteries but I always have a bunch laying around doin nothin ... and you can never have a flashlight that is TOO bright and always has juice!

[EasyGoing1]

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!!

thats a good point ... ill stick with the 10

Re: Unknown Surface Mount Component

another option is to fit this to your existing board.

are you saying you want a link?
btw, shipping is often much faster than you think.

Re: Unknown Surface Mount Component

they are used in chinese lights in groups of upto 8, i'm sure there wont be a problem.

<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 ...
