I havenât tried with guppy. I donât know. Maybe you will need to add a bleeder resistor to driver.
I made something half flashlight related and half car related. I had a faulty SK68 with died driver and led. I gutted the internals and added an old XML T6 LED, and made a circuit for using as an ignition setting strobe light for my car. The circuit in the battery tube. And the potmeter is used to set the flash time. Maybe if flashing enough at a very short setting I will replace it with a resistor. The black connector connecting to car battery, and one cable wrap around the cilynder one ignition cable.
Pretty much the ugliest soldering I have ever done
Five words which shouldnât go together.
Why not?
Perhaps I donât understand what itâs used for. This quote from comedian Steven Wright comes to mind:
âI replaced the headlights in my car with strobe lights, so it looks like Iâm the only one moving.â
It doesnât shine out at other people, does it?
Aah! That strobe light is not for driving. It is for repairing and setting engine ignition advance. It has a signal from spark plug number one and the light flashes exactly when that plug fires so when I point it to crankshaft It seems to stand still when engine running. So with a mark on the pulley and some degree marks on engine block I can see the degree of ignition advance need.
So Iâm not going to blind anyone.
That makes a lot more sense.
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.
So, yeah, thatâs a great use for an old SK-68.
I always wanted to make a 18650 based XHP35 HI flashligtht so I bought this SecurityIng CREE XM-L2 from Ebay for $7.55 :
The original driver was a 20mm pressfit so I had to widen the pill to make room for the H2-C
XHP35 HI D2 3D CRI80+ on Noctigon
The quality of the SecurityIng is surprisingly good : aluminium reflector, nice anodizing with no flaws and a glass lens (not AR coated though)
Nice mod khas ! Can you share the reflector diameter ?
Thanks
The diameter is 34mm and the height is 24mm so itâs not a thrower, here is some pictures for size comparison :

Zozz, perhaps if you called it a timing light instead of a strobe light it would clear up that confusion?
Nice idea by the wayâŚ

Eagle eye X6 reflectorâs diameter is 30mm (true diameter , inside) so this must give some good throw too for itâs size too

Yes, that is the word I was looking for! This is not my native language so special tech words donât come in to my mind.
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
Motion-freezing strobes are mentioned above, are there any flashlights available that could do this?
With a operator variable strobe speed?
I work on high speed machinery and we use slow motion cameras and now Iphones that have this facility to diagnose problems.
A motion freezing strobe maybe useful possibly being able to help see into places that bulky cameras cannot.
@ CRX that magnetic momentary switch is brilliant
Brilliant indeed, man thatâs just too cool! I want one!
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:

You make some very interesting and unusual lights. I bet the Knucklehead would be a popular item if you could make a bunch of them.

I have motion-freezing strobes in several of my firmwares, either with fixed timing or automatic variable. I havenât done a smoothly-adjustable one yet, but you can get that in tterev3âs MELD if you ask nicely. I got him to drop the flash time to 2 ms, though Iâve since found thatâs too long for good motion stopping. I generally use 1 ms for slow strobes or 0.3ms for fast strobes.
Although Iâve been meaning to make an e-switch UI with operator-adjustable strobes, Iâve instead demonstrated my expertise in procrastination. It doesnât help that almost nobody except me (and now you) seems to be interested.
So⌠maybe someday?
