    Best voltage for P60 flashlight modded w/external pack?

    Glad you figured it out :D There is no easy answer, as the answer is 'it depends'. It depends mainly on the electronics inside your P60, and what voltage the drivers are most efficient on. For my P60 (Double barrel CREE R2 bike light) voltages higher than 9 Volt will give the best result. So I...

    Mudguard top light

    Here is a page describing how I built my light: Google Translation I Cut off the rear section, and replaced the boost driver with a normal resistor to connect the light to the 7V2 Li-ion battery I use on my bike. I Left a small tab to rivet the light to the plastic fender and potted the rear...

    Flood or spot for daytime see-me lights??

    :D It's a home-built trike. Unfortunately I don't know who built it. More photographs on my blog.

    Flood or spot for daytime see-me lights??

    Hi Pick, Why not build your own lights if $$ is a problem? This is what I did on my recumbent trike:

    twin headlamp with tail lights?

    This probably is not the light you saw, but may be similar. It is my helmet-mounted combination head/tail light. Information on parts used is in that post.

    What emitter is this? Cygolite Expilion 250

    Yes, the current will roughly be the same (provided that this light has a constant current driver). Looking at the XM-L datasheet, the XM-L will deliver 200 to 280 Lumens at 700mA, depending on tint and bin. Typical forward voltage is 2.9V at that current. So your gain of replacing the XP-G with...

    I Think it is a CREE XP-G

    Very noticeable :) You may send me a couple of them to mount on my trike ;-)

    I Don't use that camera any more - it's a VGA cam and quite bulky. Neither do I use that VM (It is an aluminum Alleweder). This is my 'best effort' for the 808 cam - it will have to do. Plugged the microphone hole, and drilled a smaller one further away from the lens. Then glued on some foam...

    Project Aura: a college bike light project

    Then I'll see you in court! Internet is fast. Even Wikipedia has already stolen some of my ideas! http://en.wikipedia.org/wiki/Wireless_energy_transfer

    Project Aura: a college bike light project

    Exactly, slip rings would not survive one winter over here. Perhaps not even one summer :D Convert the battery power to AC, then use a transformer to transfer power from the one (stationary) coil to the other (rotating) coil. At the wheel, rectify the AC back to DC. or Convert the battery...

    Can I wire up multivoltage Led drivers is series on my e-bike?

    Taskled's Hyperbuck driver has an input voltage range of 8..80VDC and has an adjustable output current up to 1500mA. It is the "Ideal LED driver for ebikes with up to 80V battery packs." http://www.taskled.com/hbuck.html

    Thanks for the advise, again :) The rattling problem I mean is on a different camera, different bike (or rather, VM). This one: Lot of rattles coming from the Alleweder, but also from the camera. I Looked at your videos of riding in Sidney on Youtube. Very nice. Reminds me of riding in...

    Thanks. looking at your page, it also dawns on me what the rattling noise is coming from another camera. The battery.... Have pulled that camera apart three time already to find what's making that noise. Here is my first attempt on wind noise reduction: Movies captured on the recumbent Trike...

    Dutch Recumbent Trike Lighting Project

    I Thought about making a jack for an external microphone, but i like it to be simple as can be. The original hole is indeed behind the ring. I drilled a new hole just to the side of the ring. Looking at the photograph, i suspect a piece of foam will not do it, unless I install a clear window...
