Gesture Controlled Raspberry Pi Rover

In this video I demonstrate a gesture controlled Raspberry Pi rover I created as a pet project. I recently purchased a Adeept Mars Rover PiCar-B and thought to extend it by adding gesture control functionality to it.
For gesture recognition, I am using a NodeMCU wired to a GY-521 (MPU-6050) breakout board. The NodeMCU constantly reads the 3-axis accelerator readings and transmits them to the Raspberry Pi rover over MQTT channel.
Though I have used Adeept Mars Rover but this application is not specific to it. You can use any rover/car and customize the driving logic accordingly.

Homelab With 20 Raspberry Pis

I’m sure a lot of you have seen my previous post “My Humble Homelab (With Raspberry Pi Rack)”.
I’ve made a few big changes to my server rack since that post so I thought I’d share. Most notably, I’ve gotten rid of my 2 Dell R710 enterprise servers and replaced them with…10 Raspberry Pi 4 Model B.

Below is a table explaining in order, exactly what I’ve got in the rack now.

High-resolution display output or Wi-Fi: It seems you can only choose one on Raspberry Pi 4

Users of the Raspberry Pi 4 mini computer are puzzling over an issue where setting some display resolutions have the side-effect of killing the Wi-Fi connection.

The problem was noticed by developer Enrico Zini, who is working on a digital signage box using the Raspberry Pi 4. “One full day of crazy debugging, and the result is that if the Raspberry Pi 4 outputs HDMI at a resolution of 2560×1440, the Wi-Fi stops working,” he reported.

Oracle Builds a Supercomputer with 1,060 Raspberry Pi Computers

Raspberry Pi is definitely the world’s most popular single-board computer brand, and that popularity is primarily a result of their low cost and small size. Those factors make Raspberry Pi boards ideal for compact projects, and for portable devices in particular. Oracle, however, has taken the complete opposite approach and built a supercomputer made from a cluster of 1,060 Raspberry Pis.

Raspberry Pi 4 Firmware Updates Tested: A Deep Dive Into Thermal Performance and Optimization

The Raspberry Pi 4 launched earlier this year to critical acclaim, thanks to upgrades including but not limited to a more powerful processor, the first new graphics processor in Raspberry Pi history, true gigabit Ethernet connectivity, and PCI Express-connected USB 3.0 ports.
It also drew some criticism for its higher-than-expected power draw and, correspondingly, heat output — something the engineers at the Raspberry Pi Foundation have been working to address in a series of firmware updates.
