    Serious FOCer (84V VESC 6 based controller)

    Excited about all this! I've been very impressed with the capabilities of the VESC but have been waiting on a high voltage version before building my next ebike and the Little FOCer would be just the ticket. Not concerned with enclosure issues personally as I will have my own custom version. All...

    2 years after the summer of peanut butter gear Bafangs???

    :arrow: A custom order of sensored Bafang BPM motors in a range of speeds was made by me last year :wink: Most the motors are in Australia but some are with cellman in China for cheaper global distribution. I'll put details up in the For Sale section in the next few days. - Ben

    Doc EXTREME 36 FETS controller

    A note on Kapton materials: not all Kaptons are the same. Eg 'Dupont Kapton MT' posseses "3x the thermal conductivity and cut-through strength of standard Kapton® HN". http://www2.dupont.com/Kapton/en_US/products/MT/index.html This seems pretty significant as it suggests 3 x 3 = 9x the...

    Magnet wire for motor harness

    Finally, relief from the burden of wondering where the hell it was that you came from Luke! :lol: Or, perhaps I'm misinterpreting. Were you discovered enjoying a particularly hot and chaffing-free "skin/skin situation" in the space shuttle's cooling system?

    Simple ebike 'fuel gauge'

    Regarding cheap and effective display options, could these units be employed? Price is about $9 (inc post): http://cgi.ebay.com.au/Digital-Thermometer-Temperature-LCD-Module-Gauge-C-F-/110627111029?pt=AU_Gadgets&hash=item19c1e3c075#ht_2367wt_918 Just cut off the sensor and feed it a (biased...

    Bafang BPM Pics and Specs - Large 3.9Kg Sensorless Geared

    Was pleased to discover that full throttle lives local to me Down Under :D I recently got to test his BMP motor set up (with 16S LiFePO4) and loved it. The BPM was surprisingly quick and smooth to start without sensors. I tried a few WOT starts from rest and (perhaps after a tiny delay before...

    e-crazyman controller oddities

    The first of these 206s that I modified would cut out when the throttle was applied too suddenly. I discovered that I'd put the wrong value power resister in by mistake (the big grey one standing up near the big capacitor) and was able to correct it and solve the issue. Is this a possible cause...

    Bafang BPM Pics and Specs - Large 3.9Kg Sensorless Geared

    Thanks for the initial review. This motor looks like a nice step up from Bafang's smaller motors - such as the SWXH which I've been enjoying lately, but find it gets too hot easily for my needs. Full-throttle, you mentioned a "top speed of 37 km/h" for your code 13 wind. Is that on level ground...

    Single speed E-BIKE advice

    Personally, I would test your system out with rear gears, then remove them if desired. The optimum gearing set up will depend on so many things - riding style, terrain, and the characteristics of the particular motor - that it's hard to know in advance. I think that having a range of gears on...

    Hi all. Here's a summary of this thread I made as preparation for my 6 FET 116 controller project that its been suggested I post. Its mostly just cut and pasted but will save people wading through the 51 pages of this meandering tale to find the right tech stuff :wink: I've updated it to...

    New 'Mini Monster' Programmable Controllers Coming

    Great to see some progress. The 'Mini-Monster' has been mainly mythical at my end. My box of a dozen odd parts for 10 controllers is still lost in transit (and uninsured :cry:) Hopefully, it shows up sometime, somewhere and not in a picture on a ransom note from Somali pirates... I will split...

    New 'Mini Monster' Programmable Controllers Coming

    "Every act of creation is first of all an act of destruction." - Pablo Picasso Great reporting! Regarding the possible cause of the FET failure: The regen conditions don't seem to be much of a candidate: '-10A', <90V I assume. Though rated to 100V, 112V has been reported for the 4110s. Do...

    New 'Mini Monster' Programmable Controllers Coming

    The software indicates that there are 3 electronic brake strength levels: "0: normal, 1: strong, 2: very strong". I don't know if anyone has tried them yet. For those new to the term, Electronic braking (EBS) is not be confused with regenerative braking. EBS dissipates braking energy through...

    New 'Mini Monster' Programmable Controllers Coming

    Stator, Nice work on the power traces and thanks for the pics and schematics. swbluto, A bunch of tiny, add-on sensorless boards from Keywin went out to people a while back but I haven't seen any reports. Anyone?

    New 'Mini Monster' Programmable Controllers Coming

    In a technology trickle down from the big end of controller town comes... The 'MINI MONSTER'' series of controllers. 6-FET circuit boards with IRB4110 brawn and '116' chip brains promise to do a big job in a small package. Yes, the wait is (nearly) over for compact, multi-kW, instant-throttle...

    Zippy Flightmax / Turnigy lipo testing

    I like the combination of getting bulk loose cells at wholesale prices (as bearing mentioned) and then building desired packs quickly with a range of purpose-designed and published PCBs as offered by Mike, and/or made by Gray. This route would involve some group buying and then distribution...
