Raspberry Pi Zero Clock by Robert J Sheldon iii

简介

A Pi Zero Clock? I know what you're thinking, "Isn't a Zero a bit overkill for a clock?" For a normal clock, probably, but with the internet it can be so much more than a normal clock! You could make a clock that automatically adjusts across time zones based on it's IP address, or perhaps a clock to track your latest amazon order. For me, the clock tells me when the next subway train is coming at my stop. This is a relatively simple build that requires some soldering, but all off-the-shelf components. BOM: a 1.2" 7-segment display from Adafruit in whatever color you want a Raspberry Pi Zero and supported power chord some female to female jumper wires a small wifi dongle, preferably one that you don't have to compile the module for (ahem) (for the non press-fit version) 4 M2.5 screws and 3mm spacers There are two versions of the clock included: the original design features a removable backplate and requires some M2.5 screws and spacers, but results in a slightly more visually appealing clock as the seam is hidden at the back and on the corners and the layers are vertical. The press-fit clock requires no screws and features a bezel on the front of the clock, but the clock has to be split horizontally instead of vertically. If you are a better EE than I you could certainly buy just the display and some resistors and skip the I2c backpack altogether, opting for some protoboard or even posterboard to hold the clock in. If you're going that far you could also snag a cheap display…
