i think i was the naysayer you're talking about (
https://news.ycombinator.com/item?id=35980709) and i have one slight correction
i think the display is fucking awesome
just. not for this
for applications where its lack of backlight and grayscale mean you get a significantly longer battery life, or smaller battery, or no battery at all
being able to maintain the display on 50μW means you can run it off a cr2032 coin cell for 17 months
if you pair that with a cpu that's using some similar amount of power, probably due to being in a low-power deep-sleep mode 99+% of the time, you can get a month or two of interactive computing out of a coin cell. a sleeping esp32 is supposedly around 10μW, and at full speed it's about 200 32-bit mips at 1 watt. microcontrollers are typically an order of magnitude lower energy per instruction. ambiq's microcontrollers are two orders of magnitude lower, like 30 picojoules per instruction, so 100 μW should give you 3 mips
400×240 is half the screen resolution of the original macintosh, and the same as the vt100, though with a different aspect ratio
so you can get a vax in your pocket that runs off a coin cell for six months
that's motherfucking amazing
but that is not this product
which reminds me, i'm late for a pairing session on a jit compiler targeting the ambiq apollo3 ultra-low-power 48 megahertz cortex-m4f
