I wonder what's the point to run.batteryless? With such a small power budget, the device should accumulate energy when it can harvest more than it needs to consume, and use it when the lighting conditions deteriorate. It would only take a really small battery, but would seriously increase usefulness.
- kragen 2y agoi've discussed the reliability problems of batteries further in https://news.ycombinator.com/item?id=40805573 https://news.ycombinator.com/item?id=40805573, but, as an intuition pump, consider that when cellphone repair shops advertise particular repairs, the particular repairs they advertise most are battery replacement, charging port replacement, and broken screen replacement
- nine_k 2y agoSo use a battery of a standard form factor and make it easy to replace. E.g. one AAA battery per device is easiest. Most coin-sized lithium batteries are also rechargeable, explicitly or implicitly.
- kragen 2y agoyou don't seem to have really understood my points, because you aren't engaging with them; as it happens, you're also mistaken about coin-sized lithium batteries (though any battery can be slightly recharged)
- thetoon 2y agoWhat do you mean by implicitly? Last time I checked, most of button/coin-like batteries (CR2032 and the such) aren't know to be rechargeable, unless you specifically get rechargeable ones.
