Just in time for Pi Day (March 14, a.k.a. 3.14, for the less mathematically inclined), the Raspberry Pi foundation released a new Raspberry Pi board. Of course it’s not the Raspberry Pi 4 but simply a Model B+ for the existing RPi 3. Like almost any other Pi before it, it’s a step up, though small, in performance without changing the price one bit. Being Pi Day and all, it’s perhaps the perfect time to remember, or see for the first time, some of the coolest Raspberry Pi projects around.
