Product idea: Pinebank, 18650 multifunction power bank/speaker/light/etc - cowsay - 10-03-2025
Hello .. just passing along a product idea. It is a product that doesn't exist that I've always in the back of my mind wished for.
I dub it the Pinebank. It is a versatile, open source, extensible, multifunction power bank that uses off-the-shelf replaceable 18650s for serviceability and long term utility.
Maybe low power RISC-V under the hood like the pinecil
Here is a 18650 DIY power bank for some additional inspiration https://www.youtube.com/watch?v=_PBr_jUA4Iw
The hypothetical Pinebank at its core it has 3 primary functions: Power bank, light, speaker
General use cases:
* General purpose power bank
* Bluetooth speaker
* Flashlight
* Work light
* Diffuser cap for lantern operation (power outages, camping, etc)
* Strobe for emergencies, maybe even red light beacon option
* Display function: clock, alarm, weather, radio
Some ideas (some possibly as pluggable module/daughterboard addons):
* AM/FM/NOAA weather
* Connections for solar panels for off grid/emergencies
* SDR/Radio transceiver/antenna for radio geeks/search and rescue
* WWAN
* Lora
* It's a stretch, but it's possible that it could even be used to jumpstart a car or pump up your tires. Like this product https://halo.acgbrands.com/en_US/bolt-air-black-graphite.html
Since it has a processor, you could use it as a little low powered micro server. Lots of options here.
Perhaps it is not possible to cram in ALL of these features, I'm just airing ideas.
I think something like this would be incredibly useful. Seems like a good fit for Pine.
