I haven't developed on the Kindle ecosystem, but with old Nook devices I am able to set a screensaver, alarm, and put the device into deep sleep between refreshes. This changed my battery life from ~48 hours into 30+ days of battery life even with some old devices.
The "electric sign" app does this, which is where I referenced the code.
With trmnl, the image only refreshes every 10 mins so the device will set a ~9 minute alarm to wake the device right before it needs to load the next update.
The refresh period is also configurable so a slower refresh interval (e.g. every hour for less time-sensitive screens) yields larger battery savings
Not that I'm aware of, but there are some great projects on the XDA Forums and GitHub I was able to reference in order to make basic apps for Android 2.1.
For those on a budget, I highly recommend checking eBay for old e-ink readers. Many of them can be rooted and are by far the most affordable way to get e-ink (plus compute).
Yep. From the perspective of someone earlier in their career without all the "lived experience": Business books have helped me feel closer with (and better emphasize with) senior execs. I'm not necessarily trying to cut corners, but it helps in situations where I am expected to be a peer to folks who have been working much longer than I have.
Business books are definitely not a perfect substitute for lived experience or having a mentor, but they have certainly helped me.
excited to use this with my react codebase! have been waiting for something like this for some time, but really like the decisions and tradeoffs you made
