    Home mades

    Hi all.

    I have been inspired by your creations.

    Made some cheap lights for new bike. Cost me $15.00. I used some carbon fiber scraps, to make a lost-foam-method carbon fiber part. It's just a big headset washer really. Bought two 20watt tracklight bulbs for $6.00, couple toggles for $5.00, some speaker wire in the bsement, and the li-po pack from my heli.

    Built it all up, wired it, and I'm charging the battery now. I'll hook it up and mount it on my bike later today, and I'll get some more pics when done. I still have to get a voltmeter/cut-off for the lipo, and do some burn time figuring.

    Thanks for the inspiration

    Hi Witch, looks cool I'm a suka for a bit of carbon!

    You might need to get a higher capacity pack, as on full power you won't have a very long run-time!

    Way nice! Love the "headset spacer mount"....don't think I've seen that done before.

    6v or 12v bulbs? If 12v, they may be a bit yellow/dim on the 11v pack. Overvolting to 14.4/14.8v will make them real bright without affecting the bulb life enough to worry about. And as BH mentioned above, runtime may be short. I used a 5Ah 14.4 NiMH with my dual halogen light...plenty of juice for my typical 2 hour night rides.

    You may find that you need to paint the back of the bulbs to block the annoying light bleed-through. I used black woodstove/grill paint. Handles the heat fine, and would look good with your beautiful carbon fiber.

    It's not about speed, it's about lack of control.

    Ya. I'll get a higher cap battery in the near future. Just kinda trying it out with this one.

    The bulbs are the 12volt models; and ya, not as white as some of the nicer bulbs out there, but They're pretty bright. I'll try them tonight in the yard.

    The bleed through tip is a good one. I'll see what I have around to blacken the backs out.

    Do those bulbs heat up your cables and brake lines? You might want to keep that in mind when you not moving, I know my halogen bulbs put out tons of heat in front of the bulb. Another way to block out the back of those bulbs is to use some foil tape, I used some on the back of my wife's bulbs and it actually put out a bit more light in front, the foil tape conforms to the bulbs nicely. Nice looking light! I'm going to have to look for some carbon fiber myself.

    Those look like 6 volt halogen bulbs??
    A bit on the low powered side and kinda yellow, but they will work.

    That pack will need way more mah to power those bulbs for any length of time.
    Those halogens use a ton of current and get very hot

    Most of the older lights that used those halogen bulbs had at least 5 of the Sanyo Ni-Mh 4400 mah cells in a pack.

    Question:
    What is that red/black connector leading to your battery pack?
    That looks like something I could use.
    Do you have a link to a source?

    Thanks

    Nah. They're 12v Noma tracklight bulbs.

    The Heat wont affect any thing around them. They're secured in high-temp silicone, on a200-degree post-cured laminate, and all wiring is sealed in an augmented epoxy.

    Ya, bigger battery packs are in the works.

    Don't which you mean exactly, but the connectors are Dean's Connectors. The main black & red wires are the power leads. THe smaller connector is the balacing connector, for the Lipo.

    Ok, Dean's connectors.
    I did a search and they seem to be used in RC stuff.
    I am always looking for simple two prong DC connectors.

    deans are some of the best! I have a ton of them. I first started using them with my rc stuff, now I seem to use them on lots of projects.
