Building a Real-Time HN Display for $15

Nice project. The $15 price point is genuinely impressive for something like this.

I've been curious about e-ink displays for a while but haven't taken the plunge. What's the refresh rate like in practice? And does it actually help you notice interesting posts you'd otherwise miss, or is it more of a fun desk decoration?

Satisfying to see all the payload request and response sizes in bytes not kb.

Q: the display just starts at 0 and increments comment id by 1 every 10 seconds. Has the device caught up to latest? If you power cycle it, do you have to run through all historical comments?
