If I took apart a flashlight for a project some time last year, gave up on that project, then do something entirely different with the host this September, can I enter this year’s OL contest?

I don’t see why that wouldn’t qualify for the modified light category. I’d make it clear what condition you’re starting from and just go from there.

“Hey I took this apart and never did anything with it. I have an idea for the OL contest, so it’s build thread time” or that kind of thing. Doesn’t seem like a big deal at all. If somebody said “Here’s a C8+ I modded last year, it’ll be the basis for a new mod for the modded light category for this year’s contest” that isn’t much different and still qualifies Smile

A question regarding parts eligibility in the Hand Made Class....

I am well aware that flashlight heads, body tubes and tail caps CANNOT be used in the Hand Made Class.

What about a part like the brass PILL from a ConvoyS2? It would be a convenient way to mount a driver. The other parts used in conjunction with the pill would be formed from sheet metal or plumbing parts.

Thank you.

i do not think i’m gonna use 3d printer this year, i’m disappointed with durability and strength of printed parts, maybe some internals , i found craft grade\marine grade plywood to be the most durable.

I would say since it is pre made specifically for a flashlight , no. Not up to me though – just an observation.
Of course a plumbing fitting is also pre made, but it’s not made for a flashlight and there is the difference. Maybe you could find a threaded ‘bung’ or ‘stopper’ from a plumbers/electrical merchant like this sort of thing ? – search google for ‘brass conduit plug’ to see more types

Short answer - sorry no

Long answer - I was going to automatically say no but went back and checked the rules from previous years.  Justin did allow P60's to be used (but ONLY P60) I guess because they were popular.  The P60 was omitted last year.  So it wasn't an easy clear answer.  It was your own wording that tipped me off - "It would be convenient....".  Convenience is using machines or existing lights (both the other categories).  Well this comp is named a 'challenge'....  <img src= " />

That is what I thought and I have an alternate plan, but I thought I would check first.

Good clarification - that had been my assumption as well, in regards both to a Convoy S2+ pill and an S2+ triple spacer that I found in my parts bin. Basically my reasoning was, other than the listed items from the first post ("reflectors, drivers, LEDs, O-rings, switches, lenses, clips, sheet metal and tubes etc") if it's made for a flashlight, it's out.

Good to have you on board grin 

 

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

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.

LOL, Big Smile true, but remember this year , everything is upside down and sideways. Silly
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?

Hi Mieciu.  Yes your build qualifies for the 'Modified Category'.  You'll need to make a thread for it and show as much as you can how you built it.  It looks very interesting and I'm looking forward to seeing more  <img src= " />

I do think this is a good idea. I said something similar in this thread . However it was also pointed out to me that if the persons already interested in the comp decided to team up in pairs then it’s possible to get even less entries than we currently get. It also begs the question (if we introduce this new category) why have the limit of only one entry per person? Personally i think anything that can entice more overall people to get involved can only be a good thing. However it has also previously been mentioned to me that some people are wary (or possibly even embarrassed) to enter if they know the other participants are ‘too good’.

It’s a fine line to try and open up the restrictions whilst still keeping the home hack interested in having a go… Anyone who has an opinion one way or the other I would like to hear it Beer

Started new thread – will upload more pictures/movies later Smile

EDIT: I also have 1 underwater project – made from scratch without using any of existing flashlight parts.
Can I submit new thread in ‘Machine Made’? category

EDIT#2 – I’ve just red about only one single build limit in this contest….
