While the Raspberry Pi Zero is still a pain in the butt to actually find, it’s still an undeniably useful little device once you get your hands on one. One of the neat things you can do with it is turn it into a USB device that you can easily program from another computer. This used to take a lot of steps, but DIYer Andrew Mulholland found an easy way.
Essentially, you’ll just need to burn a copy of Raspbian to a SD card, then edit two text files. Once you do that, connect the Pi Zero to your computer with a USB cable and it will appear as a USB ethernet device that you can program to your heart’s content, no extra USB keyboard, mouse or monitor needed. Head over to Andrew’s site for the full guide.
