We’ve all got a pile of old devices lying around somewhere that are waiting to be torn down for parts, or turned into something useful. [Peter Voljek] decided to do the latter with an old Kindle eBook reader, turning it into a neat message board that can be stuck onto a fridge. With the addition of some server-side Ruby code, you can send messages to this by email, and it automatically displays the last message received. Throw on some magnetic sticky tape and you have a neat fridge door noticeboard.
Hey, why not combine this with the Kindle weather station hack to create a noticeboard that tells you what you need from the store, and reminds you why you shouldn’t leave the house at the same time?
