Did you add a 7V supply somehow for the torque sensor? Do you use the torque or just PAS?

Wow wel done! I had the same thought about the torque sensor not working on a lower voltage. I never tried a higher voltage Nice that you use an ESP32! I recently worked on some other project with a Wemos C3 Mini, it has Bluetooth making it perhaps easy to add some information and control via...

Yes that's different from mine on the side of the sprocket You can try e-mail the manufacturer for specifications

Maybe you can tell from the outside, here are some pictures of mine

Here is a picture of all the connectors on the original ampler controller I remember now, the 5 pin green one might be a "normal" Julet connector, not a Julet mini This one: https://nl.aliexpress.com/item/4001091169417.html?spm=a2g0s.12269583.0.0.20463c1eZzJOIv&gatewayAdapt=glo2nld And of...

I think it was because the original anti spark switch had a latching button. The one I use now uses a momentary button, so I think you can use the original switch yes

I didn't manage to ready out the torque sensor, would be a nice feature! The is the pinout of the sensor: Pinout pas sensor Red A1 PAS A Black A2 PAS B Blue A3 analogPin (torque) Green VCC Yellow GND I also attached a pdf of the manufacturer of the pas sensor

Here are the 3D files for the housing, I also attached the Fusion 360 file so it's easier to modify

Here is the Arduino source attached, in the vesc.ino.zip I used the analog inputs to read out the encoder signals, there is some arbitrary threshold in the code to read a high or low on both these signals (340 and 750). Maybe these values are different on your setup. After boot you can rotate...

Hey, the original anti spark switch I used blew, I swapped it out with this one: https://flipsky.net/products/anti-spark-switch-smart-280a-for-electric-skateboard-ebike-scooter-robots?_pos=1&_sid=279ba950c&_ss=r But because this was a bit larger that the first one, I wrapped the whole thing in...

Looks like the anti spark switch I used is blown, it now stays on the on state. :roll: Is this expected behaviour when it is blown? This one: https://www.banggood.com/Flipsky-AntiSpark-Switch-Pro-280A-for-Electric-Skateboard-RC-Car-Model-Parts-p-1349674.html?cur_warehouse=CN

This project took me quite a while, before I started I didn't know a lot about electric bikes, and their components. I got a lot of info from this forum, so that's why I wanted to share this project I decided, because of reasons, to convert my Ampler curt to an open source controlled Ampler...
