Good to have you on board grin

I did a small edit to help make it clearer regarding existing flashlight parts.

41

And to expand upon that…. if a factory made flashlight reflector or lens is okay one would assume that includes an optic. ??? But pretty much no other part made for a flashlight.

42

Correct. I made another small edit.

43

:+1: Good show!

Now to see if my mental visuals can come together.

44

I started a topic for this build over here….

LOL, :smiley: true, but remember this year , everything is upside down and sideways. :stuck_out_tongue:
There is a machining project on the table with all the internals ordered and in hand with material ready to be machined. However machine time is a real problem for the time frame, this one is time consuming, so we will nibble on it in pieces until completed, then post afterwards. :wink:

I am trying to understand why only few members are taking part in the challenge and thinking maybe some only have mechanical expertise and other electronics exoerexpe.

Maybe there is an option to allow forum members to participate as a team of 2. One will build the body, and send it to the other member to do the electronics.

What do you think? It may create friendship among members

Hello

I’m not sure if my project is ok with any category:

- I took Courui D01 head + reflector

- Made thicker pill

- Removed 0,5mm from reflector to get better focus for XHP35HI

- Replaced glass lens with thicker one

- Made ‘underwater’ body on my small lathe

- Made a custom driver (piezo switch + attiny85 providing fast pwm to some simple ebay driver)

- Made a waterproof plug to use with separate battery(4s3p)

  • Took it 63m(206feet) under water and it survived, I still use it for my deep diving in cold dark water.

It’s not simple mod, nor 100% made from scratch…
I have some pictures/yt movies.
Am I qualified to compete?
