DJI/Ryze Tello Mini-Drone Review
DJI/Ryze Tello Mini-Drone is, as the name suggests, a new and tiny drone from the people who created my lovely DJI Mavic Pro. The important differences are, however, compelling:
Running Raspberry Pi AND Arduino for the Best of Both Worlds
I have been writing a lot more about Raspberry Pi than Arduino lately, but don’t get the impression I am leaving the Arduino world behind. Both devices have their benefits, and in fact, I believe they work really well together. Let’s take a look at the easiest way to do that!
Linux Automation Tips: Create a Boot/Start Menu with Python
You may have seen in the Maker Hacks Facebook Group the latest iteration of my Raspberry Pi based entertainment center. It’s now got to the point where I need a boot menu, so I thought I would share the code and implementation with you! Code See the full code in the Gist. First we need […]
