Extended BLDC-TOOL with Watt Control Mode, PPM Cruise Control, individual Throttle-Curve and Android App

I will give it a try again this week and will keep you update.

Hello, can we use cruise control with this remote ?? https://fr.aliexpress.com/item/Wholesale-New-arrival-2-4Ghz-mini-remote-controller-with-receiver-for-electric-skateboard-longboard/32678995218.html?isOrig=true#extend

I don’t think that it works. If you would modify the switch to a button which you can press and automatically switches off when you release it then it would work. But the other question is also what signal you get. For example if the output is 5V then it would be to much for the VESC. But with some voltage dividers it could be modified then. I recommend the Mini Remote for cruise control. Works great.

I made a little update of my App. It is possible now to make the Data Visualisation a little bit transparent in the Video mode. Just go to the Video settings and enable it if you want. This way you still can see a bit of the rest of the video. Tell me how you like it and if you have better ideas then let me know.

Thank you Ackmaniac for this fantastic watt control mod and these awesome throttle curves. I recently added a 2nd SK3 6364 to deal with some hills here but the fun on flats totally suffered, it’s a beast and the power and acceleration was just scary. Now with your mod it’s fun again! :slight_smile: I played around quite a bit with the breaking, that was even more scary before your update with a 2nd motor even though I cut the breaking amps way down to 6A per VESC. Now i like the breaks again. Here are the throttle setting that worked best for me so far.

After a lot of rebuilding, improving and bad weather I finally had the chance to do some logging. Still with modded FW2.18. Need more tests on the small board before I upgrade the monster to FW2.53.

peak power was around 7,8kW (176A battery - logfile) peak motor current was around 435A (blocked - video)

Setup: 120A motor max / 60A battery max 12s30Ah 4x VESC 4.7 with 0,005mOhm Shunts, extra caps, extra TVS diodes and heatsinks 4x c6364 with embedded sensors

F****** awesome to see my app on that monster. The power consumption is crazy. 72 Wh a km on average. I would call that a record. But you still see that the average current is low in the active and riding Tab. But something doesn’t work properly with the original firmware. Because you only get one Reatime data update a second. Normally it is 8 till 9 a second so it would give much more data. But i will test this evening with the original 2.18 firmware to find that bug and then the information would be much more fluent and much more detailed.

Jepp, I also noticed the low sampling rate, will make further tests… More time resolution would be great!

Another record is 800W of friction losses when freewheeling (end of the video). Have to blame my ‘gamma ring’ sealed gearboxes for that.

Also sometimes it seemed that the logfile was written while the video was recorded and sometimes not, will try to take a closer look next time.

Found the bug already but need a little while to fix it. The log file is always written when the board moved once. SO it doesn’t matter if you take a video or not. Only when the board doesn’t move (for example to check the battery voltage) then the log file get’s deleted automatically.

Ok, this makes sense. I wondered over the strange logfile behavior while benchtesting.

Is there a technical reason why your app only supports newer android versions. Would have been great to take my old mobile out for skating…

To record your actual screen you need at least Android 5.0. Before it was only allowed to record the camera by the Android policies.

I fixed the Issues for the firmware version 2.18. Should work without issues now. Of course you can only watch the data and not change the mode because you need my firmware mod for this.

Google play needs a while for the upload but you find the file also at my dropbox account.

I would like to try this app, but I cant figure out how to download it properly… I have ubuntu 14.04, when I click on bldc tool in the downloaded file it doesn’t do anything…

@ekitesurfer You have to do it the same way as for vedders firmware. Only difference is that you use my bldc-tool mod and firmware mod instead of his.

I do not understand how to use yours instead of his…

I had the same problem, when I tried to start the downloaded BLDC Tool via double click.

You have to do a right click on the file, choose ‘Properties’ go to the ‘Permissions’ tab and activate the checkbox ‘Allow executing file as program’.

That solved the problem for me.

already tried that, doesn’t do anything for me…

Just go into the folder with the terminal and run “make”. After that it should be runnable.

Maybe a stupid question but did you ‘click on bldc tool in the downloaded file’ or did you unzip the archive (BLDC-tool_ACKMANIAC_Mod_Ubuntu_2_53.zip) in a new folder and clicked on the BLDC-Tool file?

Folder with a terminal? This Ubuntu stuff is beyond me…
