Re: Soft Latching Circuit for Anti-Spark Switch

I have been testing out the Vedder-Fetcher style anti-spark switch and although it has worked longer than the other cheap switch, I am starting to have problems with it. The switch is not broken (Stuck on) but after rides where lots of current was pulled, turning the mechanical switch to the off pos...

Laser Cutting Longboard Griptape

I have been quietly working on an extraordinary electric longboard build (build log coming soon) and one of the things I wanted to do was a custom griptape job. I have seen how they are typically done and they are usually imperfect. Having access to a laser cutter in the lab I work at, I decided to ...

Re: Building the Cavedioboard

I made a quick model in SolidWorks to better illustrate the idea. Obviously the thing to do from here is to make a mount for the hall sensor. I think something that bolts in with the truck would work nicely and could be 3D printed or even water jet cut. The best way to mount the magnets, especially ...

Re: Building the Cavedioboard

Very cool project. I am curious to see the results of the real-time torque adjustments while riding. In order to actively sample the angle, you will need some kind of sensor. A few things come to mind for this. A flex sensor would do the trick with some calibration. They are very sensitive, inexpens...

Enertion VESC-X First Look

Recently, I was able to get my hands on one of Enertion's VESC-X beta samples. Enertion basically hired an electrical engineer to redesign the VESC into the new unreleased VESC R6.0 layout. To be clear, this is not the VESC R6.0, only the VESC 4.12 that has been re-designed in the L shape. The board...

Re: Arduino VESC Remote

Ok so a lot has happened recently. I had to put the project on hold for a little bit to catch up on some other work but I am now back to working on this. I have done a fair amount of work over the last two days. Firstly, I rewired the OLED display from SPI to I2C to conserve digital pins. While I ha...

Re: Motor Dynamometer

So I have redesigned the model and I am much happier with the results. I have reduced the side panels from four to two and it is substantially more rigid now. The more centralized design also allows for much easier access to the wiring and motors.In addition to that, I also made the wire feedthrough...

Re: Motor Dynamometer

I recently got back around to working on this project. I have had a model for a while now but I never had the time or money for the electronics. However, a friend of mine just gave me his board (was a senior design project I helped him with) and I now have two extra vescs and r-spec motors along wit...

Loaded Vanguard Deck 3D Files

In the beginning of my longboard project, I spent quite a bit of time looking online for a 3D model of the loaded vanguard deck and could not find anything. I even contacted loaded directly and they didn't have any models either. I decided to model my own using various high precision tools. If you a...
