Title: I suck at herding electrons
Post by: Shoganai on January 17, 2014, 09:01:36 PM
I've been chatting with Scott Underscore about this but I thought I'd throw it out there anyway.



I need help to re-create this, more or less.

My intended use is to read Iron Butt bonus paperwork in the dark hands free and whatever else might come up like maps.
It needs to be as bright as a high quality LED flash light because I'll most likely also use it to work on my bike at night if stranded somewhere.



**************************************************

THE LAMP

I bought these that I may or may not use because they are huge. 23 mm may not fit there but the price was good and I always have uses for LED's.

I would LOVE to use this

Do I need a heat sink with that?




**************************************************

THE SWITCH

See this remote pressure switch, I like it's compact form but couldn't find any that wasn't prewired for flashlights.
If I got one, how hard would it be to modify for this project?

In order of preference, I would like the switch to do this ...
1. on - high - medium - low - off
2. on - high - low - off
3. on - off



I bought 10 of these from China already, just because they looked cool and might work.

I don't like the Dynamic mode on this and will have neuter it or cover it.


Variations of the switch type can include pressure / tactile / trigger / bite as long as it's attached to the helmet and is waterproof.




**************************************************

THE POWER

I want to power it with cr123a batteries. (NON-rechargeable)

It would be sweet if I can slip them under the rear padding of the helmet. If not, they'll have to be mounted on the shell.
If mounting on the shell, I need something VERY much like this.
Waterproof with a thumb screw easy to open and close cover.

(Look at the battery pack)

**************************************************

I need your thoughts on how to wire the LED's, a switch and some 123 batteries together so that it ALL inside the helmet or at worst the batteries are mounting on the shell.

I need to understand how much heat is created and how to manage it. I figured it would most liked need to be housed in a plastic sleeve within the closed cell foam of the helmet core and to direct the light away from my peripheral vision.


Also, I need a working model by March first.
Yeah, no pressure at all.

Ride with joy,
Gwen

All fixed.

(If that wasn't proof enough I suck at herding electrons, I don't know what would.)
