    Hi everyone..i am new to this forum. By profession i am an electronic hardware designer and recently started working on Arduino. I found the project discussed here very cool. Thanks fort sharing such a cool thing. Hope this will be helpful for me to learn something new about the Arduino. I want to know you attached the relays on the same board if they do not cause any temprature effect?

    Arrow Hijack/revive

    I wonder if I can revive/hijack this thread.

    I've been thinking about this project and would agree on the Arduino Nano / IRF540 MOSFET combo. This is "down the line" for me atm to reduce cabling and add features that the bike doesn't have yet.
    The 4 way variant is ~$5 on Aliexpress (search for "Four Channel 4 Route MOSFET Button IRF540"), the Nano only about $2 these days (crazy, huh? - order a spare).
    With the port limitations:
    one could drive 8 MOSFETs, measure a voltage/current or three and display something (LEDs/OLED/small SPI TFT.
    I also considered the now ubiquitous Wemos D1 mini, but it doesn't have the pins (e.g. port extender) and needs extra 5V etc. It could always be put on later for added functionality.

    (Mechanical) compatibility with pre-wired fuse boxes would be handy, too, e.g. this.
    This could be a very compact and fairly cheap powerhouse. Any thoughts?
