Hey fellow Neopixel/WS2812 fans: know of any in-production versions of smaller LED rings using 3535- or 2020-sized WS2812/SK6812 LEDs? (as opposed to the standard 5050 sizes most rings use) Seems like it’d be a great solution for putting around pots/encoders. I can’t find any on Ali #ws2812#sk6812#rgbled#neopixel
Hey #electronics folks! <3 I want to build a CO2 sensor with a battery life of several months. First using prototyping boards, then maybe as a custom PCB.
Some questions:
What kind of approach/device would you suggest to measure the power consumption of such a device? I hope to end up in the single-digit mW range.
What would be the lowest-power components required to drive a small e-ink screen?
Does the 328P seem like a suitable controller, if I don't need any connectivity?
@blinry Feeding LoRa transmitted data from the #Watterott CO2 Ampel to #Checkmk monitoring on the Input side and querying the REST API on the output side to show service states on a bunch of #ws2812.
If you want to take the sensors to talks, feel free to ask us at the Checkmk booth at #Fosdem#fosdem24 in K, ground floor. We will happily borrow you one for an hour or so (we will have three in rotation).
Ho ho ho, 40m of WS2812b rgb LED’s ready for Christmas fun! I can’t decide what to illuminate first… I think my bike needs some light! Will definitely save one box for Xmas decs though.
