Raspberry Pi CM3+ based EagleEye Smart Camera Works with OpenCV and LabVIEW NI Vision

Raspberry Pi CM3 Industrial Smart Camera

We previously covered Q-Wave Systems’ Melon S3 board combining a Xilinx Spartan 3E FPGA with ESP8266, but the Thai company is back is a completely different product: EagleEye Smart Camera. The board is powered by Raspberry Pi Compute Module 3+ (CM3+) with 16GB or 32GB flash, and equipped with a 5 MP camera for machine vision and robotics applications. There are two version of the board Uno and Industrial with the latter adding 24V digital input and outputs, circuit protections and support for industrial temperature range. EagleEye smart camera key features & specifications: SoM – Raspberry Pi CM3+ with Broadcom BCM2837B0 quad core cortex-A53 processor, 1 GB RAM, and 16GB or 32 GB flash Camera – 5 MP OV5647 image sensor, CS/M12 lens holder + 4mm CS lens Video Output – mini HDMI port Networking – 10/100M Ethernet USB – 1x USB 2.0 host port up to 1.2A Expansion Uno […]

Khadas VIM3 Linux Benchmarks and Comparison to Raspberry Pi 4

I received Khadas VIM3 Amlogic A311D SBC in early July and started testing it with Android running some benchmarks and playing games last month. I was impressed by graphics performance and overall benchmark results in Android, especially the results I got with a heatsink matched Khadas own results with heatsink + fan. So I installed the latest Ubuntu 18.04 available at the time (July 19) in order to repeat benchmarks in Linux and see how it goes. System info in Ubuntu 18.04:

I decided to install armbianmonitor to draw some nice temperature charts as I did with Raspberry Pi 4:

wget https://github.com/armbian/build/raw/master/packages/bsp/common/usr/bin/armbianmonitor
sudo cp armbianmonitor /usr/bin/
sudo chmod +x /usr/bin/armbianmonitor
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2C0D3C0F
sudo wget http://goo.gl/vewCLL -O /etc/apt/sources.list.d/rpimonitor.list
sudo armbianmonitor -r

wget https://github.com/armbian/build/raw/master/packages/bsp/common/usr/bin/armbianmonitor

sudo cp armbianmonitor /usr/bin/

sudo chmod +x /usr/bin/armbianmonitor

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2C0D3C0F

sudo wget http://goo.gl/vewCLL -O /etc/apt/sources.list.d/rpimonitor.list

sudo armbianmonitor -r

But I had some error during installation:

sudo armbianmonitor -r
Installing RPi-Monitor. This can take up to 5 minutes. Be patient please/usr/bin/armbianmonitor: line 189: /etc/armbian-release: No such file or directory

Now you're able to enjoy RPi-Monitor at http://192.168.1.8:8888

And while I can load the webpage with top menu appearing, it won’t show any data, as its name implies it may only work in Armbian. SBC Bench on Khadas VIM3 Let’s download SBC bench:

Using Sony PS3 Eye Camera as an Inexpensive Microphone Array

Almost exactly two years ago to the day, we published an article showing how microphone arrays performed against a single USB microphone, and the latter started to have a poor wake word detection success rate at around 3 meters array even in a silent room, and it got worse with white noise or background music, while the microphone arrays would pick up the wake word with a much higher success rate in all conditions. The price of smart audio development kits varies a lot from $500 for Intel Speech Enabling Developer Kit to $129 for an Allwinner R18-based 3-Mic Far-Field Amazon AVS Development Kit, and $99 for ReSpeaker Core v2. If you’ve already got a Raspberry Pi 3/4 board, you can get cheaper options such as ReSpeaker 4-Mic Array for $25, but nothing beats the price of Sony PS3 Eye camera that comes with a 4 microphone array and sells […]

CutiePi Open Source Tablet uses Raspberry Pi Compute Module 3

The announcement of the CutiePi, an open source tablet-based on the Raspberry Pi Compute Module 3 comes a bit late for the Pi-based tablet/laptop space. We have reported on some of the more versatile tablets using the Raspberry Pi platform, the Diskio Pi 13.3” DIY Tablet and the RasPad tablet kit, with a few more Raspberry Pi-based tablet/laptop kits also listed in the same article. Timeline and Pricing CutiePi Tablet has no firm release date, but the company is saying late 2019 for launch. The development team is also saying everything is subject to change, but look for the pricing to be USD $150 – $250. Click to Enlarge How CutiePi is Different The tablet is different in its thinner design and in the software designed specifically to use Linux Raspbian OS for a touch screen platform. There are readily available source code and case plans for the ambitious developer […]

Embedded Linux Conference (ELC) Europe 2019 Schedule – October 28-30

Embedded Linux Conference Europe 2019 Schedule

I may have just written about Linaro Connect San Diego 2019 schedule, but there’s another interesting event that will also take place this fall: the Embedded Linux Conference Europe on October 28 -30, 2019 in Lyon, France. The full schedule was also published by the Linux Foundation a few days ago, so I’ll create a virtual schedule to see what interesting topics will be addressed during the 3-day event. Monday, October 28 11:30 – 12:05 – Debian and Yocto Project-Based Long-Term Maintenance Approaches for Embedded Products by Kazuhiro Hayashi, Toshiba & Jan Kiszka, Siemens AG In industrial products, 10+ years maintenance is required, including security fixes, reproducible builds, and continuous system updates. Selecting appropriate base systems and tools is necessary for efficient product development. Debian has been applied to industrial products because of its stability, long-term supports, and powerful tools for packages development. The CIP Project, which provides scalable and […]
