8th Old Lumens Challenge is CLOSED !!!

MtnDon and YuvalS have finished their builds. Well done guys 

I hope everyone has their parts ordered.

Well, my possiblity to enter this year’s contest is slowly fading.
One important thing for me would be to have appropriate drivers and unfortunatelly I’ve not been able to order it/them (as I would chose the modding project meanwhile…).

So, maybe I won’t be in after all. Let’s see how next weeks go…

Congrats to the ones that have it finished yet and good luck for the still ongoing projects :beer:


Thanks, although I still have to take some final pictures :)

Is there any chance that one of the "TBD" prizes will be a headlamp?



Packages from china arrive in about 2 weeks now so you still have some time ;)

Well, to here they normally take almost a month, but I am not ordering from China.
I would order from our member Lexel but maybe due to his recent conditions or being busy he’s been absent for a while.
So I’ll have to wait for a reply.

As I announced in post #12 I started a build thread for my 20cm fresnel lens thrower that I would like to use to enter the competition this year.

I’m not sure though in which category it should be, or even if it fits any of the categories. It is almost entirely made from scratch, with loose parts, but it does use a 21700-size battery tube/switch from a Yootoo SD2, because that is IMO really the best and safest way to make a battery carrier for this build. So that makes it fall out of the handmade category. But it is not a modded flashlight either, or you would have to call it a heavily modded SD2 :smiley:

Any ideas if this can be an entry this year? If not, I’m fine anyhow, I’m having a lot of fun building it :slight_smile:

Hello everyone. Apologies for the delay in up keeping this thread. Aside from being busy at work i just cycled 240km over the weekend in a place that had in/out phone reception. Getting back on track now.... [quote=MascaratumB] Well, my possiblity to enter this year's contest is slowly fading.

If you eventually get your parts you can always go ahead with the build :-) Or wait till next year ;) [quote=YuvalS] Is there any chance that one of the "TBD" prizes will be a headlamp? laughing [/quote] Good question. I'll investigate but don't get your hopes up :ARROW-RIGHT: [quote=djozz]

I did think your build is worthy of the OL comp :star: It would need to go in the modified category. I understand it’s not a conventional modification but the last point of the handmade rules is pretty clear. Shall i add it to the modified list?

Yes please! :slight_smile:

Great to have you aboard djozz :sunglasses:

Just getting started, I had upgraded the reflector to a 86mm and it arrived yesterday. So I will be starting the build today. :wink:
.

Ooh upgrading before the build has even started… nice :laughing:

Upgrading or changing before starting the build has the advantage of not wasting effort ias would happen if the build had already started or been completed. I have been thinking about a possible change. This time a change of choice, not one forced upon me by a materials failure.

So, I am just asking if there is any rule or reason that I should not redo my light entry to the point of making virtually all new parts and assemblies? What has been done so far would pretty much be ignored except for a few small portions. I would make notes in the first posted message that things changed and to jump to where the newer concept starts. Only the newer light would be the entry.

I know, crazy.

Hmm... changing course during a build is not so strange but doing a major redesign after the build is finished is a little unusual. Off the top of my head I don't recall seeing that before. But that doesn't mean it cannot be done. Providing you use at least some small parts (or one large part...?) then effectively its just a very late change to a handmade light. Have at it :-)

Now I’m feeling like a slacker !

You're a slacker no more, Rdubya18 :-) Welcome to the comp

Between deer season and the holidays, I know the end of November and December will disappear fast. So I’m trying to crank through mine quickly. Hopefully I can get this near completion in the next few days.

  • Sat Nov 14: conceptual design established
  • Sun Nov 15: materials assembled and rough testing
  • Mon Nov 16 (so far): firmware tweaks

Also… bump! The more the merrier in this. Let’s keep the tradition going. It doesn’t have to be overly complicated. Heck, make a portable potato light or something (a potato counts as a battery, right?). You guys (and gals) can do this!

I have been working so many hours havent had time to even mow my lawn. Another week or 2 the hours should drop back a bit and I will have some time.

Come on guys! About a month left!

I just completed my build :smiley:

Boogered mine up “ fixing it “ As soon as new driver arrives , I’ll be back on it .

gchart , congrats ! Your build came out nice .

Ok, I’m gonna join as a last minute one, and it’s kinda part made now - I just need some advice as to what cat to put it in lol.
It was an old broken penlight. I have harvested a reflector, switch and driver from it. the rest is binned.
I have (not going to lie) used my lathe a tiny bit, but it isn’t machining - more harvesting threads from plumbing fitting as i can’t turn threads.
Most of it is hand made though lol!
Which cat to put it in ? :person_facepalming: (I presume machine made as I lightly used the lathe?) I’ll leave it to PP lol!

Great to have you aboard G0OSE. I’ve put your build in the Machined category as you suspected. The bright side of that is if you need to touch up the lathe again ……
