Hi Espruino Team,
I'm working on the development based on Puck.js v2.
And I'm pretty satisfied with the hardware spec and development environment.
However, many of my clients are asking for the rechargeable feature of the device.
So I'm curious that will the rechargeable battery spec (maybe Puck.js v3, v4, or.... ) be released in the future?
Or if there has an existing spec relevantly similar to Puck.js v2?
There aren't immediate plans right now for a rechargeable Puck, although probably the next one I make will have an nRF52840 which has USB, and if it has a USB socket then rechargeable does make sense.
However, something like Bangle.js actually has a bunch of similar features (accelerometer, magnetometer) in a similar size, plus also display, GPS, waterproofing and rechargeable battery.
I'm also in the process of sourcing a boxed, AA-powered device with accelerometer, which might work for you too? For most things that should put the battery life squarely into the 5+ year region.
Which features did you need for your projects?
I currently deal with signal of acc and gyro for motion detect. Some features might require highly sampling rate to accomplish. Therefore, a rechargeable Puck might be the best implementation for clients in several scenario. It is fine so far as I kept the features in development. I'm looking forward to the nRF52840-based device!
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
