While I was at OggCamp, I noticed a few people had repurposed supermarket eInk shelf displays as name-tags. Nifty! I wondered if there was a retail version I could hack around with. I found the HSN371. It is a colour eInk screen with a lanyard hole. The picture quality is amazing given the technology, the […]

I'm a little bit obsessed with building eInk displays. They're pretty cheap second hand. They're low energy, passive displays, with good-enough performance for occasional updates. Here's a new one which shows me what the current cost of my electricity is: Background After installing solar panels, a smart electricity meter, and a solar battery - the […]

Behold! Thanks to the power of the Watchy development platform, I now have all my 2FA codes available at the flick of my wrist! HOWTO This uses Luca Dentella's TOTP-Arduino library. You will need a pre-shared secret which is then converted into a Hex array. Use the OTP Tool for Arduino TOTP Library to get […]

I have the new Watchy eInk watch. It has a cute little screen with a resolution of 200x200 pixels. How much text can we cram in there? A typical watch face looks like this: My new watch face is far superior and looks like this: That's using the GNU Unifont - which works brilliantly on […]

At a glance, I can see the next bus, whether there are delays on the Elizabeth Line, and if my regular trains are running. Here's how […]

It was garish to look at. And it was expensive. The Watchy is the opposite in every single conceivable way. […]

(Mostly notes to myself) KOReader is the best eReader software I've found. It works beautifully on eInk screens, Android, and Linux. Just a gorgeous - and infinitely customisable - experience. There's one thing I don't like - to move forward a page, you have to click the right of the screen and, to move back, […]

A little under a year ago, I got a Boyue Likebook Ares eReader. I use it most days. Recently, I noticed a yellowing discolouration around the edge of the screen. I've boosted the contrast of those images. It's the sort of thing the human eye can detect under decent light, but cameras struggle with. At […]

Here's a quick tutorial for turning an old Nook into a passive display. This is an update to my 2013 post End Result An eInk screen which displays the trains I can catch from my local station. It shows the next few available trains, and whether they're delayed. It also shows how long until the […]
