Here ya go you have your choice of the original Flux Capacitor :D http://www.oreillyauto.com/site/c/detail/EB00/121G.oap?keyword=121g Or the upgraded Mr Fusion model :thumbup: http://www.oreillyauto.com/site/c/detail/EB00/121GMF.oap?keyword=121gmf Mind you even without it your bike looks not bad |

Very happy for you Simon!! :clap: :clap: :clap: :clap: :clap: I imagine that it will create interest every time you take it out. :thumbup: I kinda like the gyro gearloose/mad scientist look with the wiring in the breeze and the batts akimbo, and the test pilot's gaze of serenity. Now that's the way to enjoy life! :med: Of course I look forward to the spiffy version just as much! When you have time to give us some current and voltage figures I can help you tune your motor and drive combination to give best and most efficient performance. :smart: But solving the slip problem comes first! Suggestions for further thought: It's possible to pivot the drive roller outboard and forward of the rim contact point so it draws itself in to the rim when power is applied. This overcentering would probably allow a lighter spring. Also, I think the idler pulley might not have to be spring loaded at all, rather, overcenter locked in a contact position -- the drive roller will apply pressure to it through the rim anyway. The idler should be able to be unlocked manually. maybe just an overcenter lever control. Anyway, :thumbup: :bow: :bow: :bow: |

Well this is off topic. I've been waiting for some left hand nuts to arrive through the post so i've been messing with that Atari ST I found at a boot sale. This audio/video cable is probably the fiddliest soldering job ive ever done. Shoved the 13 pin din connector into an eraser to prevent the pins from wandering when the plastic got soft from the soldering heat. The pins didn't have solder cups. There was more space on the scart side, but it was even more of a fiddle making sure every cable went where it was supposed to. See if you can spot the typical mistake! And it works! Well the cable does at least. Unfortunately the floppy disk drive seems to have problems, but hopefully they're the kind I can fix. I'm not in so much of a hurry to complete the bike at the moment though since it's dependent on if I can get ahold of laptop cells at the next boot sale. Hopefully the weather is good on Sunday and the folk selling old computer junk will turn up. And hopefully they won't expect the same crazy prices laptop batteries sell on ebay for... Also, am I right in thinking that if I made something like a 7s 3p battery, to balance charge it i'd only need one 8 pin connector, or would I need 3 8 pin connectors for each battery in series? |

Thanks to vtsteam for moving this thread to a more sensible forum, and giving it a better title! |
