Shoganai · Posted: Fri Jan 17, 2014 9:58 pm Post subject: I suck at heading electrons

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.
http://www.webbikeworld.com/r2/motorcycle-helmet/police-helmet/police-motorcycle-helmet.htm

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.
4X 10W white LED eagle eye Car Motor Daytime running DRL Tail Backup light bulb
http://www.ebay.com/itm/4X-10W-white...-/161105292363

I would LOVE to use this
12mm CREE XM-L T6-5C 10W 900LM 3000mA 6000-6500K Neutral White LED Chip Bead - White + Silver(3.0-4.2V)
http://wallbuys.com/

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?
Mini Night Evolution Airsoft Tactical Flashlight LED 180 Lumens QD Mount

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.
Mini In-Line LED Strip Light Dimmer Controller with On/Off Switch

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)

http://www.batteryjunction.com/fenix...FYNi7Aod63wA9A

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

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. Shocked

Ride with joy,
Gwen

All fixed.

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

Gwen,
I can help you with the electron herding, but I can't answer your questions off the top of my head. If you want to shoot me a PM, I'd be more than willing to figure this out and then post a "how-to".
I'm not sure a CR123 can provide enough current for those CREEs. Might have to do some playing around.
Housing the CREEs would be another challenge. Maybe make a little mold and cast one in some epoxy??

Thank you Bill.
I'll take you up on that.

Time is in short supply as I really want to have this in working order in 30 days, so this is the direction I'm heading now. I just don't have time to build this project from dead scratch.

These are the LED's I'm going with. I'll be using 4.

http://store.ijdmtoy.com/Bolt-On-High-Power-LED-Eagle-Eyes-p/sku222.htm

I gave up, at least for the time being, on the H-M-L switch and went with sweet jewel.

http://store.ibexsports.com/exposure-lights-remote-switch-

Waterproof, rugged, tiny AND surface mount!

Next was power....I went with this battery pack.

http://www.amazon.com/Fenix-BT20-rechargeable-batteries-EdisonBright/dp/B00BB6SELE

I searched for WEEKS looking for a waterproof, EZ to open pack that would hold (4) CR123a's or (2) AA batteries AND not be a sealed rechargeable type. When I found what I wanted, no dealer would sell me JUST the pack.
To get the battery pack it took me calling the company and buying 4 directly from them.

NOW...all I need to do it wire the four LEDs in parallel then to the switch then to the battery pack.

I'm going to hard wire LED's to the switch the wire in a waterproof IP67 locking coax quick disconnect between the switch and the battery pack.

Any other suggestions?

Gwen, you should check to make sure that that $55 Shocked

switch will work with 12V LEDs.

I already did.

It will handle 4 CREE's and I'm not asking that much of it.

I'm REAL, real nervous about cutting up my $600 helmet....just saying.

Ok...

Here is the 150lm LED held next to where it will mount. The circle shows the final location.

This is what I'm thinking of doing.

Any thoughts?

Thank you Bill.
Space being limited, I've decided to only use two.

I'm still struggling with understanding how to run them parallel.

Do I need a resistor like what I read here?

Perfectly clear.

I just tested them (a pair) directly to the battery on the bike.

OMG those little suckers are bright and TWO is all I need. *blink, blink*

This is what I have so far.

Drill bit marked with blue tape for depth gauge.

They aren't as bug-eyed as they look here.

I'll go as far as routing the wires then stop until I get the switch in.

I just got called into work at about the time I got to a stopping place.

LDrider reading lights almost done.
Awaiting the arrival of a switch and a battery holder.
Each 150 lumens; 300 total.

A thought just occurred to me.
You may want red lenses on those LEDs to reduce the night-blindness you're sure to experience.
Not trying to prolong this project, mind you.
