    Ebikes at Maker Faire Bay Area 2014

    I only had 4 hours at the show today (didn't exhibit this year) but only spotted half a dozen e-bikes and none of the regulars. But the booths were scattered all over this year and it was extremely commercial as well-- are small makers just passing on Maker Faire now? Will post pics in the...

    Doc in California !!

    Hey Doc glad your trip went well. Was gonna say you're welcome to park in front our house in San Mateo but you've left the area :) I've taken an RV from here up to Washington and back and didn't have too much trouble. Parked at Walmarts and in residential areas. Just be polite and stay out...

    XC846 based ebike controller?

    I'm looking for an XC846 based ebike controller (preferably sensored) but its been a few years since I even logged into ES and I'm not sure which vendors use these anymore. I modded one 3-4 years ago from Ecrazyman, but I've blown one of the phases and it keeps blowing again and again... so I'd...

    ES Meetup and Project Showcase at SF Maker Faire, May 18-19

    Good meeting some of you at MF, either again or for the first time. Makes me wanna dust off some of my ebike projects. My pics are here (I still need to upload the ones from Saturday): https://plus.google.com/photos/109989603094714012775/albums/5880082785262699777 I really dig the Juicer and...

    Sony Konions from Makita Packs as Laptop Batteries?

    Heh, it went like this: The CSR asked me if I'd ever let the laptop run down to 0%. I said yes, it had happened once, just recently before the battery stopped working. He said, "Oh, you damaged it then." I told him batteries don't die suddenly; electronics do, and the electronics in battery...

    Sony Konions from Makita Packs as Laptop Batteries?

    Good point on the energy density. I would rather keep the Makitas for EV use. They are out of warranty now, though they stopped charging while in warranty (wedding got in the way...). There is a Makita service center across the bridge from me, I wonder what the likelihood of getting the packs...

    Sony Konions from Makita Packs as Laptop Batteries?

    I have 2 Makita packs that wont charge anymore. I have a Thinkpad which runs for 30 minutes on its battery. This is the third battery. The replacements all use crappy cells. Pack voltage is 14.8v-- I assume 4s2p. Any issue with using cells from the Makitas?

    Android and Iphone what apps?

    I've been using the app recently to map some rides. Does not yet provide any statistics, though that's from a lack of time to code it. In the attached map, I turned it off then on, resulting in the "leap" from one spot to another... Works surprisingly well though. I'm at the point where I...

    Android and Iphone what apps?

    The Arkon mount arrived and it works much better. I'm a bit worried because the handlebar clamp is sized such that it won't go over the fatter part of my MTB bars. This could be a problem on my Downtube since it's already festooned with accessories. For $15, it's higher quality than I...

    Android and Iphone what apps?

    It's been frustrating testing without a mount for the phone. Riding around looking at a phone is probably a good way to get killed. So I ordered the Arkon handlebar mount from Amazon. But I was a bit impatient for it to arrive so I made a ghetto mount from a Gibson pickup box, hose clamp, and...

    Visiting Hong Kong...

    All right, looks like I will be getting a tour of a motor factory... it was a bit hard to figure out what application the motors are for but it will be a good starting point. I'm going to ping Keywin about the controllers :)

    Visiting Hong Kong...

    Thanks for the tips, folks. I will need to bring extra luggage for sure to bring back all the various goodies (I got a great suit from India last year... heh). I wonder if I can pick up Keywin controllers without shipping :) That'd be like half price and a half a dozen would last for a while...

    Endless-Sphere Shirt Idea

    I am a strong believer in bold marketing. Forget free advertising for corporations. Speak the gospel of the electric church! My favorite bike shirt is one I picked up from UrbanVelo at NAHBS. Unfortunately they don't seem to sell it anymore...

    Visiting Hong Kong...

    Hi folks, I'm going to have two separate 1 day layovers in Hong Kong on my way to & from India in February. Anyone have any tips on what to check out, primarily in terms of ebikes, while there? Of course, non e-bike advice would be cool to (but off-topic for this forum, heh). I will not be...

    Android and Iphone what apps?

    In case anyone is interested... I finally made some progress last night-- I'm aiming just to overlay details over the MyTracks map for rev 1. The current speed is rather wacky at the moment. Just sitting at my desk it says I'm moving 1km/h. Sometimes there is a jump up to several hundred...

    RC Motor faces "bolt pattern"

    Hey folks, just wondering how much similarity there is between the "bolt pattern" on faces of RC motors? I had a mount machined for my Hyperion RC motor that has been working great, and I was thinking of having a few more made during the holidays but I would probably get some of the HobbyKing...

    180kv outrunner powered offroad e-bike

    Just another +1 for not cheaping out on the batteries. They are the heart of the machine, if you get a good set, they will last you through several builds as you upgrade over the years. If you get crappy batteries, your bike will be crap and you will never ride it and all the money you spent...

    Kit legality in Europe?

    Was wondering whether Europeans are able to "beat" the rather measly legal power and speed limits in the EU by ordering kits instead of complete bikes and then assembling on their own? And/Or do folks buy powerful bikes for "offroad" use and then just use them onroad? Or are y'all just being...
