    So I wanted to design a children's toy, where the electronics could last 100 years (ignoring mechanical abuse). I figured some people here might be interested.\n
    \n
    I settled on a CR2032-powered night light, using an attiny10 microcontroller, where the flash is rated for 100 years unless you're writing to it (which I am not). I did some pretty heavy power optimization. The firmware is hand-optimized assembly.\n
    \n
    When you turn it upside-down, a tilt switch toggles an LED @ 3mA via a pretty intense debouncing routine.\n
    \n
    A watchdog timer has it auto power off in 30 minutes.\n
    \n
    When off, it consumes less than 1 uA. So it has about 25 years of standby time, although the battery is only rated for 10 years (it is replaceable though).\n
    \n
    If a child uses it every day, then the battery should last about 4.5 months.\n
    \n
    I made custom boards for it -- I kept is simple with few components as possible (resistor is for scale):\n
    \n
    ![](https://voltage.vn/pictrs/image/7251a080-676e-413d-b9d7-277388f7c8ea.jpeg)\n
    \n
    I kept assembly simple. A better design would snap right in to the pins of the CR2032 holder, but that's an addition I'll make another day. I also should have added one more ground pad to solder to, but forgot. Still, an OK result I think.\n

    \n
    I used some spay-on lacquer to protect the traces a bit after assembly.

    So I wanted to design a children's toy, where the electronics could last 100 years (ignoring mechanical abuse). I figured some people here might be interested.\n
    \n
    I settled on a CR2032-powered night light, using an attiny10 microcontroller, where the flash is rated for 100 years unless you're writing to it (which I am not). I did some pretty heavy power optimization. The firmware is hand-optimized assembly.\n
    \n
    When you turn it upside-down, a tilt switch toggles an LED @ 3mA via a pretty intense debouncing routine.\n
    \n
    A watchdog timer has it auto power off in 30 minutes.\n
    \n
    When off, it consumes less than 1 uA. So it has about 25 years of standby time, although the battery is only rated for 10 years (it is replaceable though).\n
    \n
    If a child uses it every day, then the battery should last about 4.5 months.\n
    \n
    I made custom boards for it -- I kept is simple with few components as possible (resistor is for scale):\n
    \n
    ![](https://voltage.vn/pictrs/image/7251a080-676e-413d-b9d7-277388f7c8ea.jpeg)\n
    \n
    I kept assembly simple. A better design would snap right in to the pins of the CR2032 holder, but that's an addition I'll make another day. I also should have added one more ground pad to solder to, but forgot. Still, an OK result I think.\n
    \n
    ![](https://voltage.vn/pictrs/image/c89f001b-7f44-4d5b-9e9c-f1da5e97dae0.jpeg)\n
    \n
    I used some spay-on lacquer to protect the traces a bit after assembly.
