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
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 I’m not going to blind anyone.
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:
