Re: OpenSource Remote for VESC ArduBoardControl

After a few hours solved As soon i connect the Arduíno usb, VESC start dumping data on the rx port, the same port used for the upload of the new sketch :roll: The problem was that the code with Wh counting never had been uploaded, now almost everything is working, i'm still getting zero on battery c...

Re: OpenSource Remote for VESC ArduBoardControl

I don*t know why I skipped them. They are exactly the 8 bits I skipped there. Maybe I wanted to save memory? I don't really need them. I calculate a battery by the used Ah. There 2 are ways to do it. One to add this 8 bits (I can do it when I can find the time for) or simply calculate Ah*V and you ...

Re: OpenSource Remote for VESC ArduBoardControl

Any lucky with your VESC? the faults command is not giving you anything? I'm finally getting data back from VESC and into the remote, thank you sir for this library :wink: Just one thing that i think is missing is Wh in and out, from my point of view is mandatory for coulomb counting fuel gauge, is ...

Re: Modular Battery System

With a CAN bus or serial communication this is "relatively simple", each box has two high power and two rx/tx connectors on each side, onde male other female, this way you can stack as many boxes you want, each unity would act alone to balance and protectthe cells within, and the main modu...

Re: Looking inside a Boosted Board

Its somewhere in a spreadsheet in the video, 14/50 , i'm still trying to figure out how they avoid belt slip, since its only 5 teeth in mesh, maybe the motor mounts are sturdier than mine

jacobbloy, whats the shaft diameter of the motors? with 14 teeth pulley i expect a maximum of 5mm

Re: Motor reaching 90°C, go 10S?

Didn't see your post. How did you go down? Previously i had made a PCB for the Arduíno and the NRF radio module, booth fixed with female pin headers, with the vibration the NRF got loose and the signal that the Arduino send to VESC gone crazy, and VESC gone crazy because that and gave full brake an...

Re: Looking inside a Boosted Board

Great video, i would love to get my hands on a pair of this motors, lightweight and more than sufficient for most of the situations

Due the small mass i think with long hill the power may be limited to avoid overheating, any experience on that?

Re: Motor reaching 90°C, go 10S?

Update i'm with VESC for some time, limiting the current did nothing to prevent the overheating, as expected, but today i tested with the 230KV motor, awesome, still using the 50/28 gearing since i was not able to order the pulley anywhere, apparently is is way cooler, as soon as possible i will do ...

Re: OpenSource Remote for VESC ArduBoardControl

The 2.8 that you are using is the vedder original or the modified version? i'm in 2.8 and UART is working, just to be sure try this delay in the start, maybe something changed and it's causing all the problems

Re: AngelDust|Trampa HolyPro 35|SK6374 168kv|E-TOXX|Dual VES

Now i'm convinced that CF is the way to go. The foam you use is polyurethane?, and does the enclosure act as a faraday cage and block the radio signal?

Re: OpenSource Remote for VESC ArduBoardControl

i think i tried that in the beginning, but forgot later, better not mess with something that's working A alternative that i'm working in the moment is if C is pressed, read the ERPM from UART and set the control mode to ERPM for as long C is pressed, this way we avoid the nunchuck app, the downside ...

Thanks, soon i will have news about my board, that build was just a prototype, the problem is ideas, for now i have like 7 versions for the next build, it's hard to decide About the battery box, if i'm not mistaken there are no screws on the outside of the enclosure, so you use these screw inserts a...

Hello okp

I always found your board amazing, for my next build i'm on route to do something similar on the enclosures. How do you attach the one for the batteries to the board?

I'm thinking on that, but i finally sure now that te problem was the module coming out of the socket, i will solder everything and i think then it will be reliable.

i would start with refreshing the firmware, then re doing motor detection while also checking all of your wiring, then make sure that where your are located there isn't crazy amounts of rf, it can interfere but very unlikely, there is a study done buy 2 guys who hacked and controlled a boosted boar...

Hello guys

Anyone know how can i measure the motor temperature in BLDC Tool? i connected my motor temperature sensor to VESC but there is no way to tell if it's working, and in the terminal help there is no command for temperature
