Autonomous vehicles and robots navigate with sensors and cameras – but visually-impaired people still get by with canes and guide dogs. Now, engineers have developed a wearable AI system that tracks obstacles and describes a person’s surroundings.

Raspberry Pis have a long history of use in the performing arts, special effects, and cosplay. So naturally the Raspberry Pi Pico is getting into the mix.Michael Horne has a long-running Picorder …...

ESP32を用いて土壌センサを実装したので、そのやり方について紹介したいと思います。 この記事を読むことで、話題のマイコンであるESP32で土壌センサが実装できるようになります。 土壌センサは環境センサの一種で、土壌水分含有量を検出することができます。内部的には、湿度センサに近いもののようです。 これの使い道としては、例えば、家庭菜園の際の土壌の水分含有量を把握することにより、自動で水やりをするようなシステムの構築もすることができると思います。 Youtude youtu.be Arduino Nano版はこちら ◆ESP32関係の実装記事◆ DCモータ実装 www.takeshi-1222.…...

People have been overclocking Raspberry Pis since the beginning of time, and the Raspberry Pi 4 is no exception. I wanted to see if the Compute Module 4 (see my full review here) could handle overclocking the same way, and how fast I could get mine to run without crashing. There's a video version of this blog post, if you'd like to watch that instead: Raspberry Pi Compute Module 4 OVERCLOCKED. I have a giant Noctua NF-P12 fan that I can plug right into the J17 4-pin fan connector built into the Compute Module 4 IO Board, and for all these tests I let it run full blast, moving a lot of air over the board on my desk. Without active cooling, the SoC overheats pretty quickly under load—though you probably don't need this much cooling! At some point I'm going to work on a script that controls the fan's speed using the IO Board's built-in PWM-enabled fan controller chip which is accessible over I2C bus 10. But for now it's full speed ahead!

Station P2 Rockchip RK3568 Arm Linux mini PC offers with up to 8GB RAM, HDMI 2.0, dual Gigabit Ethernet, WiFI 6 M.2 NVMe & SATA SSD and more.

In this post we will see how the Raspberry Pi Pico can natively speak to a ROS2 graph using micro-ROS. We will set up a project in VSCode, compile and upload it to the microcontroller. We thus assume that you are somewhat familiar with ROS2 development and VSCode.
