Old Lumens Flashlight Challenge 2019 - Final Results

My guess would be that it would fall under machine made, comparable to someone designing parts and using a CNC machine. But hopefully we can get an official ruling.

I’m sure if you 3d-print something that’s otherwise allowed to be an “off-the-shelf” part, like a switch boot or centering ring, that would be fine. My real question is, where does the 3-Doodler fall? It seems like a hand tool to me :stuck_out_tongue:



So here is mine:

Can I enter after I’ve made it? (should I enter) I just don’t want to , then wreck it, wished I’d never entered and look like an idiot lol!

That is a good question, maybe a smart thing to do if concerned about this would be to build and fully document the build from start to finish then if you’re happy with it make a build thread and release it in stages.

It doesn’t really matter how the build thread is released to the public as long as the work is done within the stated timeframe but allowing some comments from members is a good idea in between stages of the build I think.

It’s a FlashForge Creator Pro. So it’s FFF, the most standard printer type there is.

Yes you should enter. You cant enter when the times up. :frowning:
We all wreck things now and then. :cry:
In some ways we are all idiots here so no need to feel special. :partying_face:

Love this quote :smiley:

Man, I should enter. Been wanting to scratch build a light for a while, have some ideas I want to try out. And crossing my fingers that it will spur someone to make a production version of it.

I need a rather small diameter e-switch driver with a nice u/I like narsilM or anduril. Anybody got ideas?

Driver building and writing code is beyond my skill set- I’m just a metal working guy.

Could you be more specific? How small? Linear? FET? FET + X? Need aux LED pads?

For an off-the-shelf solution, MtnE has some 10mm (out of stock), 15mm (in stock), etc. Or there are more one-off options…

There are members here who design drivers and there are lots of designs available. What exactly are you looking for?

Dont get me wrong,I like the idea of aux leds in the switch boot, but would settle for something without. I like the ramping interface of anduril, but without the complexity of blinkies, etc…like a muggle u/I that has full brightness and an easy to use lockout.

12 would be ideal, but 14 mm would work I think. Body construction will be different than most tubular lights, hence the need for a smaller than normal driver. It is going to be a super tiny 18650 light with a tail e-switch run in a slightly different way. I’m fine with an fet+1, for a good stable, low moonlight but linear would be really nice for the option to run an osram white 1mm1 or 1mm2 near its max with any cell.

In the spirit of being helpful - You know you ‘could’ be having this discussion in your own build thread so it can be judged accordingly

  • Documenting also the Failures & Obstacles: How did the builder solve the inevitable problems? Documenting the obstacles and using the power of the BLF community to solve them is seen as a plus!
  • New Driver Design or Custom Firmware is a plus: Especially when open source and shared in true BLF spirit.

It might be harder for the judges to remember this part of your build. Just a suggestion :wink:

Great to see so many new builders. :slight_smile:

Even that is a big news. :slight_smile:

Good points! Guess I’ll start one :wink:
I don’t really care about winning, I just want to get off my butt and build something useful finally. I also wasn’t expecting such helpful input (I came from the ‘other’ forum) so getting help from such kind folks is nice motivation also.

Entered!

I’ve also never posted pictures here, so I’ve been reading all the how-tos.

Done and dusted for another year.
The final two posts are from here.

Can I bump this just to keep the interest level up… I have entered, I will be documenting and presenting my process here, but the actual start is likely a month away still.

Yes please! Bump away.

Ouch. Please watch what your bumping. :stuck_out_tongue:
