Unlike the first example, the LEDs here send a direct message. Timothy Kist used Pimoroni’s Scroll pHAT which is a 17×7 single-colour LED matrix. What if you want a low-powered solution that shows seconds? Timothy Kist’s Pomodoro timer (Pi Zero)Īn e-ink display works fine for a Pomodoro timer as long as you don’t need to see a countdown clock with seconds. Pros: e-ink allows you to communicate in English and pictures (rather than having to interpret the meaning of LEDs)Ĭons: built on a Pi Zero which you can’t buy easily these days. See Maryanne’s introduction of the Pomodoro timer on her website, and also the code on Github. Going further, with an e-ink display, you could also create a timer that show how many minutes are left, though it’s unlikely that you can show a seconds timer because of the low refresh rate of e-ink display (and how distracting it would be when it refreshes!). It’s immediately apparent and requires much less interpretation. With an e-ink display, you can send messages such as “break time” below. For example, the previous Pomodoro timer uses LEDs to tell you what’s happening, but you need to know how to interpret it before you’ll know what it’s trying to say. Maryanne’s design uses a Pimoroni InkypHAT, a three-colour e-ink display.Īn e-ink display allows the user to see a more direct message. These days you’d be spending too much time on rpilocator and probably getting nowhere.īut the good thing is that this project can be built with any Raspberry Pi microcomputer, though it might not look as elegant. The best part about Maryanne’s tutorial is how she says, “I spent too much time on Adafruit and ended up with a few Raspberry Pi Zero Ws” Maryanne Wachter’s Pomodoro timer uses a colour e-ink display and a Pi Zero ( photo from Maryanne Wachter’s website.)ĭon’t shoot the messenger.
