Yeah possible. Only removable connection I have is from the reed sensor. Everything else is soldered in place. Have to say that the reed sensor connection isn't the best, might have some issues there. But that wouldn't explain why it starts to work after a reboot or two (without moving). If I...

Have been some time since my last post, maybe I'll update now. Have been raining almost every day on July and August so haven't ridden too much. Now on September few better days so have been riding again. There were still issues even with the new code, so most likely the issues are elsewhere...

I tried to check the reed sensor now with a multimeter, but it seems to work as intended. At least I couldn't get it to get stuck with few times I rotated the wheel and let it rotate until stop. Yeah looks really good to me! Not sure where the errors / weirdness comes to my setup, but I think...

No that can't be the case, as I didn't tough the wheel anymore near that area. So the next pulses are with the same rotation energy. I rotated the rear wheel by hand maybe for the first 30 seconds, and after that I just let it rotate until the wheel stopped by itself. After the wheel stopped, I...

Hi megabobra I tried it now, and it definitely works better than the previous code. There seems to be still some weirdness happening for me, as with low speeds the electromagnet seems to stay on sometimes instead of just giving a pulse: With higher speeds I didn't notice any issues, but I...

A bit of an update from me. I did take the motor off again from the frame to position the electromagnet in a better place. But no matter where I put the magnet, the speed was always fluctuating still and I couldn't understand why. I then plotted how the electromagnet was acting and there was a...

Thanks for the answer. I just tried reducing the resistance to about 59 ohm total, and unfortunately the fluctuating is still happening. I was actually hoping you wouldn't say the reason would be coil placement 😅 If that is the case, I need to remove the motor from the frame again. It is a bit...

I have noticed some issues with my mega. The speed is fluctuating a bit every now and then. For example, I might be doing constant 19 km/h according to the Kiox display, but suddenly it goes up to 23 km/h and then back to 19 km/h. And it goes both ways, it might drop to like 13 km/h and then...

I had 8 km test ride today and everything worked nicely, just like planned! Now hopefully it will work in the future as well without any error messages. Thanks @megabobra for the idea for the electromagnet! Lot's more fun riding a bit faster than 25 km/h 😉

Unfortunately the same way as you did, with a phone 😄 I wouldn't look too much at the absolute values, but more on the relative. I think it is accurate enough (Samsung Galaxy S21+) for that kind of work, especially to see if the magnetic field is 25x more than what is needed 😁 I used an app...

Thanks for the tip, but nothing came up from that location either. And yeah, 2 seconds is better than 5, I modified also my code for that 😁 I then did what I should have done a long time ago, measure the magnetic field strength. I plotted the rim magnet field at approx. where the motor is and...

I'm having some issues getting my megabobra working. At first I printed out Koekie's holder for the winding and filled it out with 0,3 mm wire (I managed to get approx. 100 turns into it before it was full). I'm using 5,2V for the whole system and the electromagnet was giving out 3,2 ohm of...
