If you’re a fan of DIY electronics, and I’d have to assume you are since you’re reading this, you’ve probably noticed the array of DIY clocks out there. Binary clocks, Nixie tube clocks, mechanical clocks powered by an array of stepper motors, RGB LED clocks, the list goes on and on. And of course we’re entertained with each new and interesting revision that someone comes up with.
On the other hand, while people seem to be obsessed with hours and minutes, DIY calendars are in somewhat short supply. You could argue that smart mirrors, or recycling an old monitor into a calendar display count, but the list just doesn’t extend quite as long as with clocks.
One interesting take on a simple calendar is the PCB Calendar from Femtocow. The material is such that it can be marked with a sharpie, then wiped clean using alcohol. Interesting, it’s available for 2017, as well as for 2015 and 2016 at a deep discount. I’m sure there’s an interesting project there somewhere; perhaps you could permanently mark dates of note from years past and place them somewhere as a reminder!
A backlight stand is also available to fit these calendars, which looks pretty neat itself. Given its array of LEDs and interesting form factor, it looks ripe for non-calendar uses as well!
