Year 2022 in review – Top 10 posts and statistics

It’s the last day of the year and the time to look at some of the highlights of 2022, some traffic statistics from CNX Software website, and speculate on what 2023 may bring us. The semiconductors shortage continued in 2022, but things are looking brighter in 2023 with the full reopening of the world mixed with forecasts of difficult economic times that should keep the demand/supply equation in check. On the Arm processor front the biggest news of the year, at least in this corner of the Internet, was the launch of the Rockchip RK3588 octa-core Cortex-A76/A55 processor together with interesting single board computers that we’ll discuss below. Announced last year, the Amlogic A311D2 octa-core Cortex-A73/A53 was finally made available in a few SBC’s, and we finally got some news about the Amlogic S928X Cortex-A76/A55 SoC showcased in 8K TV boxes, but we have yet to see it in action.

Adding an external serial console port to NanoPi R6S

I had no trouble with my first experience with NanoPi R6S while installing and running the FriendlyWrt/OpenWrt 22.03 image, but that was another story when testing Ubuntu or Debian as the mini PC would not boot at all after flashing the images with eFlasher apparently successfully, but suspiciously fast (under 2 seconds). I spent nearly four hours trying the different images and then the Rockchip Windows utility, but all my attempts failed, and FriendlyElec was not overly helpful. So I decided to connect a serial console to see what was going on. The NanoPi R6S comes with a 3-pin header for the serial console, but it’s not populated. So I soldering one, but not at the top of the bottom, and instead at the bottom since it would allow me to still use the metal enclosure to cool the processor. Some readers, or at least one, often complain about the […]

Getting Started with CrowBot BOLT smart robot car

CrowBot BOLT is a smart robot car based on an ESP32 wireless microcontroller and designed for the education market with the ability to program the robot with visual programming, Arduino, or MicroPython. Elecrow sent me a sample of the CrowBot BOLT kit for evaluation so I’ll have a look at the hardware, show how to assemble it, showcase the features of the built-in firmware, and demonstrate how to program the robot with visual programming, Arduino, and MicroPython using some of the provided code samples. CrowBot BOLT unboxing The package lists some of the highlights with 16 teaching courses, support for multiple programming platforms, scalability with Grove connectors, and the inclusion of the Joystick that’s also programmable. The CrowBot BOLT comes as a kit so there will need to be some work to do to assemble the robot, but no soldering is required (in normal cases, more on that later). The […]

Creality CR-Scan Lizard Review – An easy-to-use 3D scanner

Hey, Karl here, and today we are going to review Creality’s CR-Scan Lizard. This device is a 3D scanner that uses the structured light process to 3D scan. Instead of visible light, it uses non-visible light. I have no idea where lizards come into play but here we are. I have been waiting for quite some time for a lower-cost consumer 3D scanner. I attempted a DIY structured light scanner a long time ago, with some success…..but the time it took was unacceptable. It took me hours to set up perfectly and many more cleaning up point clouds and aligning even for a small scan. Leading me to give up on the project. I search around the Internet periodically but have never found a good working DIY solution. I am glad we are starting to see some relatively good cheapish scanners come out in the past year.

NanoPi R6S Review – Part 1: Unboxing, Teardown, OpenWrt 22.03, and iperf3

NanoPi R6S is a Rockchip RK3588S powered device that can not only work as a router with two 2.5GbE ports, but also as a mini PC with HDMI and USB ports, and an Edge AI computer thanks to the 6 TOPS NPU found in the processor. FriendlyElec has just sent me two samples of the NanoPi R6S for review. Today, I’ll start with an unboxing, a teardown, and install OpenWrt 22.03 to run some iperf3 benchmarks. I’ll try other features with either Debian or Ubuntu Desktop in a few weeks. NanoPi R6S unboxing The router/mini PC ships with 6 rubber feet (3M), and nothing else. The front panel comes with four LEDs for the system and Ethernet ports, a USB 2.0 port and a USB 3.0 port, as well as an IR receiver “window” (under the USB 3.0 port). The rear panel includes a USB Type-C port that supports 5V […]

MS2130 based “4K” HDMI to USB 3.0 video capture dongle sells for $19

4K HDMI to USB 3.0 dongles based on Macrosilicon MS2130 video and audio acquisition chip are starting to show up on Aliexpress for around $19 with free shipping. We first discovered the MS2130 chip in the YuzukiLOHCC PRO open-source hardware board that claims to have a bills-of-material cost of about $10. But you have to build it and source the components yourself, so it’s not for everyone. Now USB 3.0 adapters capable of recording or streaming up to 1080p60 uncompressed video from an HDMI input up to 4Kp30 are available to anyone with around $20. “Mini U3” HDMI to USB 3.0 video capture dongle specfications: Main chip – MacroSilicon/UltraSemi MS2130 USB 3.2 Gen 1 high-definition video and audio acquisition chip HDMI input up to 4Kp30, 24/30/36-bit depth color Video Output up to 1080p60 in YUV or JPEG output format Audio – L-PCM codec Input cable length – Up to 15 […]
