i’ve thought about this a lot because i use a whiteboard on my fridge. i would do this if it was huge like my whiteboard. like 2ft by 3ft. then i can read each day at a glance. seeing the whole month is huge. and writing on it means it should be a touch screen

i find myself wanting larger displays than is for sale a lot. i want an electric photo frame but not some 12in screen. i have great photos i want to see them 4ft tall. this is an underserved market



There are 31" and 42" e-ink displays available, but they cost a few thousand dollars. The 42" is pretty close to 2ft by 3ft, 25" x 33".

I must have 4 or 5 old Kindles in a drawer by now, somehow. I wonder if you could hack together a grid of old Kindles to make a giant e-ink screen?


A lot of these kinds of projects render out an image and send that to the display. If you did it on a server, cut up the images, and had each kindle pull their image it should be pretty trivial. The only immediate issue that comes to mind is making sure they're relatively in sync when pulling a new image if you're worried about polling too often.


With 5 kindles you get a monday to friday one for each day for starters


Might be cheaper to put a printer on top of your fridge and automatically print calendar every morning into a plexiglass holder :-)


Hundred dollars for the printer, probably 20 cents a day for the consumables (paper, toner, electricity). The paper is recyclable. At one page a day, I would guess lifetime will be dominated by mechanical lubrication or degradation of capacitors, dust clogs, etc.


Hundred dollars for the printer, I think Zou are absolutely over spending here. Electricity can be saved by having shutoff and turn on with a timer.


That could be actually nice!


You definitely need to be able to make out an Information Radiator from across a room. We’ll probably see a tipping point somewhere around a 30” screen, where you can put a large summary at the top, and details farther down.

Is anything going on? Is it worth me crossing the room to see? Should I be checking my email, other dashboards, or coworkers?
