    H3 Driving Light = eBike Headlight?

    Having thought some more (I do this slowly) the the "peak" on most scooter and motorbike lamps probably is there to achieve this shuttering effect http://s295.photobucket.com/albums/mm138/world_sport_way/motorcycle/?action=view&current=2-901-1.jpg ??? if so then these can be bought for MR16...

    H3 Driving Light = eBike Headlight?

    sorry about that, one thought I have had it to add "shutters" to the light, probably translucent such that traffic can still see some light but not get blinded. Something like "barn doors" used in stage lighting http://en.wikipedia.org/wiki/Stage_lighting_accessories#Barn_doors I currently use...

    H3 Driving Light = eBike Headlight?

    @ TonyReynolds sorry to say but i think you really underestimate LEDs, they are much more efficient than halogen and similar to HID. http://www.electronicsweekly.com/Articles/13/08/2010/46008/lumileds-produces-rebel-led-delivering-100-lmw.htm Even these, with converter ready for use on 12v (i...

    Tadpole trikes - Rear drive with regen? Issues?

    I have a trike (very homebuilt) which ONLY has a rear brake, and at under 25mph it seems to be controllable, it's very wide and has a lot of weight on the rear wheel. with the rear wheel locked up it goes in a straight line but when cornering the results can be interesting. I can only assume...

    "Mystery Meat" ESC a success! 100A 6S from Ebay $40

    a similar "mystery" esc has worked well on my bike. running cool most of the time, but going up steep hills the temperature has gone from a few degrees above ambient to about ~60+ in a very short space of time. I don't know how similar your set up is to mine but i would recommend a much bigger...

    repetitive ESC failure on low power set up

    sorry for lack of communication for a very long time thanks for the advise, the bike was up and working for a short while (~20miles) but one of the pulleys has started to slip, i will probably key it somehow. but this is by far the longest the bike esc has lasted :) i will update with pictures...

    Salvaging a low voltage/amp solenoid switch?

    washing machines are filled with 5 amp relays, i have recently taken two apart and got hold of 5 each :), i think that microwaves, dishwashers and similar also may have relays of some kind. hope this helps.

    Outrunners you've unwound? Hxt, Turnigy, Scorpion, etc.

    i know this is a bit off topic but the motor i have used is a scorpion S-4025 its small - 2000w and i have had it fail. The stator(?) spun and ripped the wires shorting and killing one of the many esc's i have killed. the motor has been run very hot, i have since changed the gearing, this may be...

    repetitive ESC failure on low power set up

    thank you for answering my questions, do you think i could include my watt meter still ? i was thinking about sourcing the caps, do you think i could use the ones harvested from the dead esc's ? - i have 3 does this wire length voodoo apply to other bike motors, i have a currie electro-drive...

    repetitive ESC failure on low power set up

    off topic but miles and gwhy you are both in the uk! i bet you both run at least multi kw setups, how do you find the bike laws in the uk? i have been trying to work out how a policeman could workout if your bike is overpowered, they don't carry amp meters do they :shock: ??? should i gear my...

    repetitive ESC failure on low power set up

    very interesting, i feel so stupid. i live in th uk so anything local is better (it seems wrong to pay lots on postage for such a cheap part), will these caps work? - http://www.technobots.co.uk/acatalog/Low_Impedance_105_Deg_C.html i also have a few caps harvested from various audio amps but...

    repetitive ESC failure on low power set up

    thank you for the advice, my wires are about 1.5 meters from battery to esc but why would wire length change anything? the cable i am using is massive - rated at 100 amps i will shorten then anyway, how short do you recommend? my setup does include a freewheel clutch on on the output from...

    repetitive ESC failure on low power set up

    i have been reading these forums and have been amazed at the quality and functionality of the bikes built, unfortunately the same could not be said for my bike. i have powered a bike using a small scorpion outrunner (2000w) here is a picture of my bike (sorry if it's massive) the problem is...

    Circuit Breaker

    When I finish my bike I will try 3 circuit breakers in parallel with a 100a fuse in series and see what blows first. This may be in a few weeks time as I have lots of work to do And also my motor will only draw about 75 amps so I may need to wire in a few 100w car head lamp bulbs to get to...

    Circuit Breaker

    i have ordered a few 30a circuit breakers to play about with, but how could I simulate a 60a load ? (I still haven’t had time to build my bike)

    Circuit Breaker

    What would happen if you put 2 or 3 30A rated circuit breakers in parallel? http://www.technobots.co.uk/acatalog/On ... s_426.html they are cheap (if you live in the uk) human
