    It could well be that your attiny85 is rebooting. Maybe its not able to draw enough power?

    Hrm I havnt tried this for a long time but I did have a solution that worked for me. Let me have a dig around my hard disk see if I still have that code.

    Dealing with Yamaha lock nut

    FYI check this video out, its in german but it shows how you remove the spider

    Dealing with Yamaha lock nut

    Ahhh yes. I can see it has "tighten" written on it. Ill just do the opposite way then :D

    Good to know, thanks for the tip, ill be careful :)

    Dealing with Yamaha lock nut

    Its a completely different shape to the bosch one. Im going to see if i can get my hands on a 35mm socket for torque wrench. Its basically just a hex nut by the looks of it.

    Dealing with Yamaha lock nut

    So I removed my cranks from my haibike all mtn sl 2016 and discovered theres some sort of lock ring stopping me taking the chain ring off. It looks to be roughly 1.4 inches in diameter. Does anyone know how the heck I can remove those so I can replace my damaged chain ring? Its sort of recessed...

    Awesome! Let me know if you need any of the 3d files. I'll be uploading them to thingiverse soon and ill post the link there when im done. I'll also update my first post with my new design.

    PS theres no need to use the internal pullup resistor with a reed switch so as you can see ive commented that line out.

    Some images here, note the attiny prototype is way smaller in size than the solution that uses Nand gates and a flipflop.

    Sure thing Geoff. Here is the arduino code: // Speed Derestrictor // Nicholas John // 22 May 2017 // // ATMEL ATTINY 85 // // +-\/-+ // (PCINT5/RESET/ADC0/dW) PB5 1| |8 Vcc // (PCINT3/XTAL1/OC1B/ADC3) PB3 2|...

    Ah nice thanks for the pics. I decided to go ahead and make my own magnet. I tweaked my code a bit and its only using 20 milliamps now. I put in a 850mah lipo with a recharging circuit so I think thatle do me :) I would have liked to have used the relays as ive got 10 or so of them kicking...

    Hrm I tried a 5v relay, how did you position it over the sensor? I couldnt get it to trigger with my relay, even with it stripped down.

    But then i'm modifying my bike right? I want a non intrusive way of de restricting. This way it can be easily removed. Theres a pull up resistor and capacitor built onto the hall effect sensor board.
