Semcon sub-€100 e-bike add-on

Pretty cool idea and concept, especially for cost-saving. I could identify of course the battery and could that be a simple Red ESC from HK as well? looks like an all HK and a pretty simple build. Maybe we should try to copy it and open-source it so we can improve on the design some more? http://www...

Re: 2 VESCs dead in 1 week?

Have you checked with Vedder on what he say's about long motor cables vs. long battery cables? Longer motor cables could maybe introduce problems in the calculation/flux.

Re: VESC Open Source - Android App Features?!?!

Torque, well my speciality is designing for minimalism and for ecosystems similar to that of Apples. But that being said there is no obstacle from porting my design to Android. We just need to nail down a clear set of API's and system calls in general and we can basically build a universal solution....

Re: VESC Open Source - Android App Features?!?!

@Benj sounds great, hey why don't you join the project it's all ment to be collaborative and open-source anyways. My expertise is mostly in industrial design + software design and some in electrical engineering (PCBs). My coding skills are not up to snuff yet and I was planing on taking the summer t...

Re: VESC Open Source - Android App Features?!?!

Actually torque he dosen't need to make any changes if we make it a separate board, we can use UART or even better the CAN-Bus to drop in and listen to all the functions. Also as furp mentioned it would having it as a separate option make it compatible with all version, prior and future VESC. As for...

Re: VESC Open Source - Android App Features?!?!

I'm actually building an add on PCB with BLE (bluetooth low energy) and iBeacon technology for the VESC. I have a rough prototype done and I'm doing the design for the iOS app as we speak. I've built it around the immensely powerful and flexible NRF51822 chip and I'm planing on making it fully open ...

Warning for the scam-artist Mare83 also know as eFlow/Marko

So this goes against every fibre of my body, but I have to write about this story as this pisses me off more than anything that has ever crossed me on this forum and in business.

Please don't copy the Richards Alien Drive work, he is just a person whom has been developing this by himself and not a big company. If we don't support him he won't have the money to continue developing new stuff! There is a tone of hard workmanship and love that goes in to his products and it woul...

OpenESC - GPL v2

So I have decided to build upon the user Reversers work found in this post: http://endless-sphere.com/forums/viewtopic.php?f=35&t=53398 and setup a GitHub repo https://github.com/OpenESC/OpenESC for the community to use. But before I set myself to work on converting their schematics to an Eagle CAD ...

Re: Reverse-engineering the Alien Power Systems ESCs

I agree with @zombiess the quality you get from various Chinese manufacturers is clearly hit and miss. I am my self developing a PCB from scratch and I also know from experience that even some of the PCB houses in China very happily copies the designed to other companies and competitors. So I would ...

Re: 3d Printed Motor Mount for E-Longboard

Would you consider sharing the CAD file right now (Solidworks or what ever you are using) and we the community might be able to help you optimize the design?

Re: Brushless dual 6kw ALIEN Power system - electric longboa

I might be out of my depth here but can't you just use a relay and and then use a smaller and more practical switch instead? I know that it's mostly switching space between items but it will help you to get a smaller switch...
