    What is the best way to protect your eBike from theft...

    Next question.... where do we get fuse? Although following this line if smoke as theft deterrant, I'd think the electric igniters from model rockets would work quite well. Might be a fun thing to play around with!

    What is the best way to protect your eBike from theft...

    How about something that belches huge amounts of smoke? I don't picture someone stealing something that looks like it might go from smoke to flame at any second. Hmmmmmm <brain melting> I had a bike stolen that was secured with a 3/8" hardened chain. They cut that chain like an old shoe lace...

    Help please, Lightweight motor for Hovercraft

    I'm sure someone can crunch the numbers, and I don't want to discourage a fun sounding project, but my gut tells me no RC motor will work, an Etek either. Even the smallest one man hovercraft use 50 to 65 horsepower engines. Unless you get close to that type of power you're just not going to...

    Yet another sports car.......

    Hydrogen fuel cells are such crap in my opinion. They will never ever be inexpensive. It will never ever be simple to supply hydrogen. It will always be difficult (read more expensive) to use them in northern climates. My prediction for the near future.... plug in diesel hybrids.

    Very cool looking rig. You bicycle guys make me want to try it out! I've always been leg lazy but with the setups you're making I could get where I needed and get some exersize too. Couple of thoughts....and I may be whacked in the head..... couldn't you drill the frame and have wires go...

    Awesome DC/DC converter 36-72v in 12v 20a out $20

    I bought one.... it didn't work at 69 volts. I tested it at 36 and it worked. I tried again at 69, a dim power out for an instant, folowed by no power. I tried it again at 36V, accidently reversed the leads for an instant...it's dead. Bums me out, if it had worked at 69 I wouldn't have been...

    Awesome DC/DC converter 36-72v in 12v 20a out $20

    Welllll.... it's not working on 69 volts. I checked the voltage before I tried. The batteries had just been charged & it was 69. I tried it at 36 volts, it worked. After one more no go at 69V I accidently hooked it backwards to 36. **POOF!** All the white smoke escaped & it's dead. The...

    Awesome DC/DC converter 36-72v in 12v 20a out $20

    Hi dee hey! He no longer puts these on eBay as he found a steady buyer at $25. He agreed to sell me one, shipping was just under $5. I Paypal'd him & got it in just a few days. I asked if I might tell you guys and gals about him & he said OK. If you want one (or more) email him at...

    First commute on my 'bent

    At first I was going to say congrats on the good trip.... but then read of the spokes. Sorry things went sour. Electrically it sounds good!

    Charging question

    If the original diagram showed the series wires making it a 60 volt system it might have been easier to understand. It was those wires that made the 6 wire idea short out when put in practice. All's well that ends well! I do appreciate everyones help.

    Combined electric bike and wind turbine.

    Here's a link to how I'm doing it. My last post shows: http://endless-sphere.com/forums/viewtopic.php?f=12&t=3247&start=30 In a 23 MPH wind I can charge four dead car batteries in an hour. (mathematically). My blades are almost 20 feet across. I don't think wings on wheels will have nearly...

    Done, and more importantly, it works. 10 wire, two for each charger.

    Pictoral tutorial.... in line fuse

    Well, ya, it's a pain to replace one, but they're kind of like a fuse inside a TV. If everything is correct they should never need replacing. If they do need replacing, the work involved is a teeny tiny portion of what's in front of you. LOL They will be part of the wiring harness on the...

    Pictoral tutorial.... in line fuse

    How to save $3. each. 1: strip wires 2: bend the ends just so 3: tin them and the ends of the fuses. Only solder fuses while that end is UP.... keep the heat from going through the fuse and glass as much as possible. Let each end cool before doing the other. I hold them gently in a rubber...

    Latest Report from LiFeBATT

    I'm going to guess the 10 yr shelf life is for lithium batteries.... not recgargeable lithiums. Just recently I bought some lithiums for a remote control temperature gauge. A yr ago they were rated 8 yr shelf life, now I see they are rated at 15 yr shelf life. The non-rechargeable lithiums and...

    Charging question

    I tested.... put two seperate batteries on seperate chargers. While they were charging I put a volt meter from postive on one battery to negative on the other.... zero volts. Then swapped putting the volt meter across the negative on one and positive on the other. Zero volts. I think that shows...

    Charging question

    Hmmmmm... it would be a total pain to disconnect all the 2 ought wires. I just went to see if they are isolated and, Waaaaa.... they are "smart chargers". Unless they are hooked to a battery they won't put out any voltage. Patrick, are you saying IF they are isolated, that it should work? The...

    Charging question

    Yaaa, the idea is to have one six prong plug. The system is not grounded to the frame, a seperate ground wire for sure. I solder every connection and heat shrink them. I nevvvvver have shorts LOL.

    Charging question

    Opinions please? I have five 12V batteries on my EV motorcycle. I have five 12V chargers. I'd like to cut & splice & solder & make a giant plug that I can plug in and charge all at once. I think I'm OK doing as in this sketch, but in case I'm missing something that would make like the 4th of...
