Thanks.

I gave you credit for trying. Good effort, the $20 cap may be unreasonable for a good lens this size with a short focal length.

I intentionally tried to pick some good things to give away because this has been a great place. Compared to what I’ve learned in my time here this hardly seems generous enough.

The people like djozz, HKJ, (removed to protect the innocent :wink: ), Old-Lumens, RMM, n10sivern, Wight, and others, have given far more to this community in the form of their time and effort. I know that I and everyone else is standing on the shoulders of tall men, and they have made it easy to light up the next mountain over, and wonder how much further we can go.

16

Wait!! What if we don’t want to be cured?!

Isn’t that item and the others mutually exclusive? If I take the cure, what would I want all that flashlight stuff for?! If I take the flashlight prizes then I’m going to run from your “cure”!

17

One day it might save your marriage. :bigsmile:

18

I actually exercise good self control with flashlight purchases, I need no cure.

What diameter tailcap board for a 3 cell soup can? Parallel 3 x 18650?
This would be something you’re in need of for one of your lights?

I ’d like to participate competing with your rules, but i m not very good yet in finding appropriate things for advanced modding… I usually end buying something useless…anyway. …is this appropriate to your terms?

Parallel 18650’s, I’m working on designing a light, so there are no specific requirements for diameter of the board, but it needs to be designed for high amps/low resistance. Good springs would be nice, but not a necessity as they will be bridged with 18ga wire.

I love the light to cure my problem, but I like the other items even better!

Great giveaway, and congrats on your 500 posts. I agree, this is a great community. Thanks.

24

I’m fairly sure the focal length is going to be longer than 100mm being only 19.5mm thick. I’ll give you credit for trying when I update the list.
