That really should have come to mind, considering how often I use motion-freezing strobes. I even helped someone time their engine once, using a similar spark strobe method, but the memory was lost in the mist of time.
I changed the tail on the CRX Knucklehead to have a magnetic momentary switch, it now works as a normal twisty still but has the optional setting of activating when stuck to a ferrous surface, switches off again when placed on wood etc again and can also be locked out to prevent this
Yeah I love this little light, it kinda came about by chance. I wanted the momentary switch which is itself magnetic and held in equilibrium by the surrounding magnet, I just happened to put the light down on that steel box cover when testing it and :laughing:
I have motion-freezing strobes in several of my firmwares, either with fixed timing or automatic variable. I haven’t done a smoothly-adjustable one yet, but you can get that in tterev3’s MELD if you ask nicely. I got him to drop the flash time to 2 ms, though I’ve since found that’s too long for good motion stopping. I generally use 1 ms for slow strobes or 0.3ms for fast strobes.
Although I’ve been meaning to make an e-switch UI with operator-adjustable strobes, I’ve instead demonstrated my expertise in procrastination. It doesn’t help that almost nobody except me (and now you) seems to be interested.
It’s a rainy day & the other day a cu BLF A01 (Old Lumens Version) came with NMM :confounded: Being as the light is essentially useless to me I decided to transplant it’s Nichia 219B (feels like in the 5000k tint?) into an old light which severely needed updating.
So just a simple emitter swap can do wonders…
My 4 sevens ti 1AA Quark originally had a XPG NW R4(or R5) put in when those emitters 1st came out & now it gets to crawl out of it’s drawer to be of some use.
Got my 3rd S41S and reflowed 219C D320 to it. Too hot to hold in 15 seconds and pulls just over 18A.
Also replaced the qlite spring on the H17f for my convoy s2+ triple with a brass button. Now that pulls 13 amps. (XP-L HI V3 3C). Pulled about 10a with qlite spring.
Last two small projects before the summer vacation :
Re-flowed a new LED in my fresh from the mail box Jetbeam JET- µ, the LED was a gift included in a recent flashlight purchase, Thanks djozz
Eagle Eye X6 with a Luminus SST-40 LED and BLF A6 driver :
X6 SST-40 6500K (left) C8S XHP50.2 3A (right)
The SST-40 is pulling 8,58A from a fully charged VTC6. I like the new emitter from Luminus but the tint is to cold for me. The drivers 45 sec step-down is about right it does get hot very fast.
Thanks for the reports on the SST-40, khas. I’m excited about the possibilities of this emitter and have ordered a couple from KD. Do you have any other quantitative output info? Like candela of the X6 with SST-40, or ceiling bounce numbers comparing it to an XPL direct drive?
The official specs states 1608 lm @ 5A with a 85C junction temperature for the N4 bin, I don’t have any reliable way to test output, but I know djozz is working on a test of the SST-40 so I will leaves the numbers to him.
I had the SST-40 in a Thorfire C8S before and got 8,09A at the LED with a 20 awg wire loop and a clamp meter.
