That was an interesting read.

I also particularly commend you for sharing a real project, with its limitations, lessons learned and ultimate failure—it feels refreshing to read something where the final step wasn't some revolutionary panacea

Agreed. I am nowhere near that space, but I found it more interesting than I anticipated. If there ever was a submission that encapsulates HN purpose, this may be it.

thanks! I definitely hesitated sharing for a while due to that failure. Glad to hear you found it interesting.

I think it truly shows great character and, as the sibling comment noted, it encapsulates what makes HN special to some of us

How do you think the LIG and elastomeric polymer blend would have held up in a washing machine / dryer?

without running tests it’s hard to say. my educated guess is it would hold up better than LIG on its own… LIG didn’t really hold up even outside of a washing machine.

generally speaking not many of these materials are designed to withstand repeated wash / dry cycles. I imagined the sensor component to be replaceable, similar to glucose test strips.
