redfoxdude Posted September 8, 2019 Share Posted September 8, 2019 Changed my tire (wanted to try the CYT), and after reassembling, the wheel isn't balancing. I think the beep code indicates either low voltage, or fallen over? The battery is at around 95%, and the app indicates that as well. To take the wheel out I unplugged the batteries, the hall sensor cable and motor phase wires, took of the little plastic pieces below the pedal hangers, lifted the LED strips out of the way, and slid the wheel out the bottom. Changed the tire (which was significantly more challenge than expected) and reassembled everything. I tried running calibration from the app to no avail. Any ideas? Is my control board somehow toast? Thanks in advance. Link to comment Share on other sites More sharing options...
Rywokast Posted September 8, 2019 Share Posted September 8, 2019 did you by chance unplug or mess with the motor cutoff button? this is exactly what kingsong wheels do when you have the handle pulled up even after power cycling, makes me think maybe you unplugged that or somehow it thinks its triggered.. hit it a bunch of times and see if it does anything Link to comment Share on other sites More sharing options...
redfoxdude Posted September 8, 2019 Author Share Posted September 8, 2019 The motor cutoff button seems to be okay, it did the usual beep indications when I press/unpressed it. I'll take another look at it, though, thanks! Link to comment Share on other sites More sharing options...

redfoxdude Posted September 9, 2019 Author Share Posted September 9, 2019 Double checked all the connections, and it all seems fine. Contacted Jason to see about a replacement control board Link to comment Share on other sites More sharing options...

chrisjunlee Posted September 10, 2019 Share Posted September 10, 2019 Those side pads though. What did you use? Link to comment Share on other sites More sharing options...

Oh yeah, I've been trying these out - they're made from a few layers of laser-cut 2mm EVA foam. The main part is about 6mm thick, and the knee contact point is about 14mm thick. I've revised the design to make the knee parts less likely to peel up over time, but still maintaining the color accent. I may reduce the rear protrusion into the LEDs, too. I'll probably make another topic about them soon Link to comment Share on other sites More sharing options...

redfoxdude Posted September 10, 2019 Author Share Posted September 10, 2019 Looks like I'm gonna need a new board, should get one hopefully some time next week. and @chrisjunlee @Rywokast thanks! I love little projects like those, and it was an awesome excuse to learn to use the laser at work hahaha Link to comment Share on other sites More sharing options...
redfoxdude Posted September 19, 2019 Author Share Posted September 19, 2019 It's alive! I got the new board and swapped it in. It is a newer version of the board, and of course they moved the unlabeled connectors around. I was able to figure it out with my trusty multimeter and educated guesses based on the surrounding circuitry. I uploaded a quick little video talking about what I found: Hope this might help someone! Link to comment Share on other sites More sharing options...
