  1. / Hey, So let me just get you to clarify a few things for me. Is the MCU and bridgedriver combined? What microcontroller is best to use. Those what you mentioned above? If the bridge driver is not included in the MCU. what bridgedriver is used. How is the H bridge configured? Filters, dead times, current sense shunts. Does the bridge driver just take care of most passive components? What IMU is being used? 6050? Aren't there massive amounts of avail lib and documentation for this chip? Advanced controls and filters. I think we could just pull from quad copter con
  2. What the heck.. That is sad.. Also, I really still see a need for this.. What the heck do I do if I ever blow up my controllers now in my 15km/h and 30km/h EUC. I'll post my schematics for the 304B board.. I had costed and BOMed out that board. It was cost effective and simple enough as a good enough foundation to start with. We can get back into it and have a look at your code. EVL was a bit nuts to be honest. Always a bit hostile and most of the reason why I originally kinda flaked off and left. Smart but only willing to do it his way or the highway. What was wrong wit
  3. CRAP!.,. I realized I never ended up posting the schematics for the 304B board from microworks.. How crappy of me. What a waste of my time :D Any value in it anymore? Mo
  4. Guys, Forgive me.. Also try not to overly flame me. I've been MIA for a while.. Death in the family and killer busy.. Sneaking off at work to write this quick note.. What is the status of HW and SW build for EUC? Last I left off about 2-3 years ago. EVL had some custom firmware spinning up a motor using generic 15km/h hw. When I also left off I had posted the schematics of the 304B microworks board. Is that board still relevant and useful? I had it all reverse engineering minus the firmware ;D In a nut shell what is the status of Custom firmware and hardware. I was al
  5. Guys... I'm back! what did I miss? Lol.. A lot obviously Mo

    Super cool. Cute for a lack of better words Mo
  7. Hey guys, Put my source files and STL on thingiverse. Please have a look ! Open source under Creative Commons http://www.thingiverse.com/thing:1370948 Keep posted for ongoing improvements. Mo
  8. Hey Guys, Tried to publish this on Thingiverse but my account is too new and I need to wait 24h. I will post it here first and post it on thingiverse when I can. Hope you guys enjoy these 3D printable parts and are able to print your own. @electric_vehicle_lover it be great to see you print somthing similar to this. You didn't give me a chance to refine it before I published but I'm already printing new top portions like the files included with rounded edges. Enjoy Mo EUC 3D Files.zip
  9. @electric_vehicle_lover Thanks Maybe you can print one of your own? Here is a video of the new EUC in Action. Regards, Mo
  10. @Tomek I used an evaluation version of Solidworks. I'm not a CAD expert by any means but I can proto some nifty things when the call is made. ABS is hard to work with Bleh.. I might consider doing a carbon wrap on this PLA @MetricUSA Hey thanks for the post. Metric and USA don't mix. A bit of an oxymoron. As for cutting myself. The edges are a bit sharp for my liking. It's no knifes edge tho. I was indenting on putting some foam around that area but I'm starting to think now that I might do another redesign. I learn a bit each time about what I would like to do next to make
  11. @Tomek Hey thanks, I used PLA, I can use ABS too and it would most likely be favorable as it's a little more durable and flexible when it comes to impacts. But, ABS tends to shrink too much and lead to warped parts when printing big things. I would need a heated chamber for my printer to print them well. The FMW parts are working great. I've done some extensive reverse engineering on the controller and it's pretty straight forward. Very similar to the Gotway. As for the motor, i've used these hub motors on ebikes a long time. They are reliable and can take a lot of abuse. On EUC's the wor
  12. Hey Guys, Thought I would share. 3D printed a body for my Fasion Micro Works Motor and Controller. I had to print the parts in smaller segments and hold things together with nuts and bolts but so far it's been working great. I took a couple of spills as well and it didn't do too badly. I've recently changed my design a little bit and am in the process of reprinting. Hopefully soon I'll have the new one together. My newer version is a bit easier to put together and is a little less wide for more comfort when I ride. Hope you all like. I can share the STL files if a
  13. Not sure why my name was referenced. I don't care for licenses and such. This is just open sourced knowledge I hope anyone can share and use. If you want to sell things and make a business out of it. By all means. Design your own stuff and go see a lawyer. For me. Share share share. Keep open. Ive been slacking to finish the rev 2 board schematics. I hope it can be used as a reference for repair and. Custom firmware. Hopefully finish this week. Mo
  14. Perhaps this brings us back to the possibility of using the GEN 2 hardware since the GEN 1 as I had posted a while earlier is an outdated and in efficient design in running the EUC. I've finally finished putting the board schematics together. Here is a sneak peak. I'll post the schematics into the hardware forum after I make a few more corrections and modifications. I still need to route this board. But i'm waiting for feedback as well as improvements and added features before I waste my time doing that. Great work so far on the firmware . Regards, Mo
  15. The bms most likely has a PTC on it that saved your batteries. The only thing you can really damage on that connector by shorting to something is your battery as it is connected to it in parallel. I doubt you could hurt anything else. The bms saved you and it took some time for it to cool off before it started functioning. My best guess. Stop measuring the voltage like that Mo
