I was sent this light, a Fritz Pocket Rocket stainless steel prototype for repair or to see what I could do with it.
It was originally a twisty switch QTC variable light which is a nice idea and had an interesting implementation but problematic for operation on such a small slippery fellow like this, plus there was a lot of damage to the system.
After some initial measurements I decided that I could make this into an electronic tail switch light, no easy feat with 57mm total length to play with.
I wanted to make the light a triple but the owner insisted on a quad setup :)
The original pill looked like it had been damaged & repaired a few times with burnt LEDs, slightly melted optic and plastic lens.
So I got to work...
A bit of a mess here so first I cleaned up the pill, soldered in a new copper shelf topside and 17mm driver retaining ring.
The original triple QTC pill setup.
Next, a 10mm hole drilled & filed in the tail to fit a 10mm x 6mm x 2mm ring magnet then a hand made copper electronic switch unit assembley to carry the switch signal to the head. Magnetic & titanium switch button.
The 6mm diameter flush button gives some balance between operation & accidental activation.
Onto the head, with a copper switch contact disc fixed onto the driver to meet with the copper switch bar when the light is screwed together, quad Samsung LH351D LEDs & Noctigon MCPCB setup, sanded down Carclo 10621 optic and aqua blue glow gasket with a MTN 17mm+1 D4 ramping E-Switch driver.Roughly fitted together.
I still have some work to do such as fix the body internals in place and some tidying up etc but just about there :THUMBS-UP:
