Show HN: Building a 42-inch E-Ink frame for generative art

For $2,200, you could run a 35W 43” $160 TV for 29 years, if your power is $0.3/kWh. In reality, much more, with a dim display at night.

I understand being eco friendly, but that’s an absurd, entirely negligible, justification.

I would claim the reflective display is the killer feature.

As the person you are replying to clearly stated, it has nothing to do with drawing power from a wall socket. It’s about enabling new uses that work on battery power that can last for months/years instead of minutes.

I see now that my perspective was too bound to the context. Thanks.

Many of e-ink's use cases involve low power environments. This is often due to logistics - not cost.

I'd love big reflective/tranflective display but I'd imagine because of rarity the prices would also be pretty high
