JUDGES:

Contest organizers will solicit BLF members in order to find judges. The identities of the judges are not revealed.

 


JUDGING CRITERIA:

Up to 10 points are awarded in each of the following five categories:

  • Skill Level / Build Quality: Judged with consideration to the person's access to tools, materials and abilities. Is the finished build functional & looking good? Was it difficult to make? Was the craftsmanship top notch with the tools used?
  • Uniqueness / Inventiveness / Innovation: Is the light unique, one of a kind, or does it operate in a special way? Can something similar be readily purchased? Were new technical innovations introduced? Were new firmware, drivers, or PCBs created?
  • Build Thread Quality: Did the contestant do a good job of showing and explaining the steps involved in the build? Were the difficulties encountered along the way documented and resolved? Was it easy to follow along?
  • Shown Operational: Did the contestant show the light operating, describe its functions, take beam shots, videos, etc.?
  • Subjective Evaluation / Bonus Points: The judge may assign these points at their discretion. Did something particularly impress or stand out to the judge? Did the contestant give it their best shot? Did they show enthusiasm for the contest? Did they support other contestant's build threads by posting encouragement or even giving help?

 


PEOPLE'S CHOICE AWARDS:

There's more than one way to win! In addition to the official judgement, a thread will be created which contains a poll, and the BLF community will vote for their favorite build. This poll will run for fourteen days. Contest participants may vote for other entrants but not for themselves.

 


PRIZE SELECTION:

Winner of the Hand Made category has 1st choice of prize, followed by winner of the Machine Made category, followed by winner of the Modified Light category.
Runner up of the Hand Made category has the 4th choice of prize, followed by runner up of the Machine Made category, followed by runner up of the Modified Light category. Prize selection will continue in this way as long as any prizes are left to award.
A special prize will be awarded to the winner of the people's choice awards.

I’ve been mulling over what to do for this year. I’m most definitely going for a lantern but I’ve yet to determine exactly HOW I’d be going for it.

This year is a good one for DIY builds. With the exception of the “chip shortage,” there are more component options than ever before. There are also more flashlights and hosts than ever before.

Convoy is now offering a lot of drivers and LEDs, and also a selection of optics. KaiDomain has lots of LEDs, drivers, reflectors, glass windows, and other optics. There are also lots of shared BLF projects on Osh Park, for your PCB needs. TaskLed’s new Ultraboost driver is a real powerhouse.

Creating your own PCBs is pretty easy to do with DipTrace, which is available for free. Their short PDF tutorial is easy to follow and you’ll be making boards in no time.

If you can’t get your raw materials locally at a metal or plastics distibutor, or hardware store, there are lots of places online to get these things. McMaster-Carr has a huge selection of hardware and materials, they are a prototype supply store! There are also a lot of online metal stores these days.

For electronic components, there’s always Digi-Key and Mouser, among others. Octopart is helpful for finding available stock of the components you need.

If you need help finding supplies, just ask! Myself or someone else will probably know where to get it.

Not yet decided if I want to build another aluminum hosing or to try enter the world of 3D printing.

Does it counts as "outside services" if I am using the 3D printer in my office?  

PS: thanks for everyone involved cool

My feeling would be that using a tool/etc. that you have access to and permission to use is not an outside service. Otherwise it would exclude maker spaces and such.

This is of course not an official ruling, just my thoughts.

Hey, glad to see the contest running this year again Wink
Thanks Hoop for taking the lead and to the organizers in the previous years for keeping it alive as well!

I will still decide on entering or not, but if I do, it will probably be with something modded Facepalm

Meanwhile, good luck to all the contestants and good work too Wink Beer

Need some ammo for your build?

No, you’ve got plenty already?

Then maybe you could spare a round and do like DB Custom did in the 1st annual Old Lumens challenge!

Now that’s a shiny bullet.

I am still not exactly sure of my entry this year, I have a general concept idea. As in previous years, it will fit into the Hand-Made category and will make use of some Wooden components. Nothing new for me there.

My topic is located here, but there is nothing I have not already said there.

Many has come and go…Sometime when I slow down to reminisce it makes my heart a bit heavy.
Marshalls of goinggear used to send me gift lights with my name laser engraved…
I have a hard time building a collection of my own because $$$ always gets in the way….Yet I have never sold a single light gifted to me. They are all the most special…

Old Lumens was a wonderful man that I respected from the early days. I am glad there is this tradition in practice annually to honor him.

Hi, I’m thinking about joining the machine made category. Is making a drop-in acceptable, even though it isn’t a complete light?

Making a drop-in is an acceptable entry for the Modified Light category. To enter the Machine Made category, the entire light housing and drop-in would need to be made by you.

For clarification, I believe a battery holder similar to the plastic type in this link would be suitable for a Challenge entry. Correct?
