Libre Computer showcases low-cost SBC with PoE support

↺ Libre Computer showcases low-cost SBC with PoE support

> Yesterday, Libre Computer unveiled a new variant of the Le Potato Single Board Computer launched a few years ago. The new Sweet Potato board is also based on the Amlogic S905X SoC as its predecessor, but targets commercial and consumer applications instead.

↺ This gargantuan 3D-printed robot hand is just the beginning

> Ivan Miranda has a humble dream: he wants to build a massive 3D-printed robot that he can ride upon. In other words, he wants a mech. But that is obviously a very challenging project that will take an incredible amount of time and money.

Bipedal robot walks with a single motor

↺ Bipedal robot walks with a single motor

> A popular goal among roboticists is animal-like locomotion. Animals move with a fluidity and grace that is very hard to replicate artificially. That goal has led to extremely complex robots that require a multitude of motors and sensors, along with heavy processing, to walk. But even those don’t quite match biological movement.

Streaming Video From An ESP32

↺ Streaming Video From An ESP32

> The ESP32, while first thought to be little more than a way of adding wireless capabilities to other microcontrollers, has quickly replaced many of them with its ability to be programmed as its own platform rather than simply an accessory. This also paved the way for accessories of its own, such as various sensors and even a camera. This guide goes over taking the input from the camera and streaming it out over the network to multiple browsers.

Testing the Coral TPU Accelerator (M.2 or PCIe) in Docker

↺ Testing the Coral TPU Accelerator (M.2 or PCIe) in Docker

> I recently tried setting up an M.2 Coral TPU on a machine running Debian 12 'Bookworm', which ships with Python 3.11, making the installation of the pyCoral library very difficult (maybe impossible for now?).

↺ installation of the pyCoral

> Some of the devs responded 'just install an older Ubuntu or Debian release' in the GitHub issues, as that would give me a compatible Python version (3.9 or earlier)... but in this case I didn't want to do that.

↺ 10 Free Online Gerber Viewers: View Your PCB Files on the Go

> Gerber files are the standard way to store PCB design images. Gerber viewers let you see the content of a Gerber file. These files usually come in .gbr, .gbx, .top, .bot, etc file extensions. You can open and check Gerber files from your browser with online Gerber viewers. No download or installation is needed.
