I'm finally starting a friction drive build. I'm going to try a Flipsky mini VESC, & while on their site I noticed that their motors look better than the Hobby King options. They have Hall sensors built in, & it looks like some have a thermistor also, although they do not mention it, so maybe...

I think I have a good idea how to figure it out. I originally thought the overcurrent circuit would be on the main board, near the output terminals, but there aren't many components there at all. There's a thru-hole resistor labeled L151 (which I don't understand since that looks like an...

For pot size, I'm not an expert, but this is what I think would work. Try to read the text (if SMT) or bands (if thru hole) to find the value of the resistor you are planning to put the pot in parallel with. Measuring it in-situ may not be accurate, b/c it may be connected to other things in...

Thanks for the information. I'll search for DrAngle. I had looked for Fetcher's limiter, but the boards are long gone. Could breadboard it, but it makes so much more sense to simply add one pot to the existing circuit. Assuming the relevant circuit is near the output terminals, there aren't...

I have several of these power supplies in my junk pile, so I would like to do the "R33" type mod to drop the current, as described here: http://www.recumbents.com/WISIL/e-bent/meanwell/default.htm I've spent a while looking at similar conversions, but have not found info for this particular...

I take back my statement about the relative IR not being important. Sorry if this is redundant to something above - I haven't reviewed all the other posts closely, but I skimmed Craig's last post enough to notice that I was being chastised, so I thought about it a little more. Paralleling...

You can parallel different capacity packs. I don't think the relative IR is important either. They always stay perfectly balanced to each other. They have to. Their terminals are on the same nodes in the circuit. RC plane guys used to do it (probably don't bother any more since lipos are cheap &...

I hooked the Reaktor to the lab supply. 18.0V works fine. 18.1V gives the error message. I didn't test the Accucell since I didn't have a suitable plug handy, but based on Hillhater's post above, ironically the 50W Accucell will take higher voltage, but the 250W Reaktor will not. Will see if I...

Not sure about those specific places, but it could be complicated. Boulder has a great network of paths. I saw a map once that showed that some of them allowed ebikes and some did not. The ebike-allowed paths seemed to be random and were not connected. You couldn't really get around using them...

Thanks Hillhater, that sounds perfect. I was rummaging through my junk and realized I've got about a dozen Dell supplies so I'll just reterminate one of them. Also noticed that the Reaktor will only work at less than one third power if powered through the jack, so I need to use the cable input...

Thanks Kinninviekid. Sounds like a little over might not work, but probably won't break it. I'll hook it up to my lab supply and figure out if it gives the error message around 19.5V.

I have a couple of Turnigy chargers (Accucell 6 & Reaktor). The manuals state the max input voltage is 18V. I have spare Dell laptop power supplies which indicate 19.5V, so they may be slightly higher, at least open circuit. Has anyone used higher voltage with these chargers, or do you have...

Looks good. Love the simplicity. I've been itching to make one of these ever since I saw yours & Adrian's original posts years ago. I finally decided to start my own build, but if I can buy your kit I may do that instead to save time. We recently bought a 44 year old house that needs lots of...

If you're going to use multiple magnets together, check out the Halbach array. If you arrange adjacent magnets with the poles alternating in a particular pattern it effectively makes 2x the flux on one side, and no flux on the other. You'd want to use magnets with a square cross section though...

I stumbled across this while searching for a centrifugal fan for my Turnigy 6364-280. http://littlescreamers.com/id57.html The kV is high (650), but it looks like a low-volume outfit that might do a custom wind or maybe let you wind it yourself. $105 shipped from USA sounds pretty good. I'd...
