ODROID-H3+ SBC review with “Unlimited Performance” mode and 2.5GbE Net Card

ODROID-H3+ Review with Net Card and Case Type 7

Hardkernel have added Intel Jasper Lake mini PCs to their ODROID-H series and they are known as the ODROID-H3 and ODROID-H3+. Like the discontinued ODROID-H2/H2+, this new series also supports the Net Card which will add four extra 2.5 gigabit Ethernet ports. Hardkernel kindly sent an ODROID-H3+ together with a selection of accessories for review and I’m going to look at the effect on performance when changing the Power Limit values in the UEFI (BIOS) together with the network performance of the Net Card. ODROID-H3+ hardware overview The ODROID-H3+ physically consists of a 110 x 110 mm (4.33 x 4.33-inch) motherboard complete with an Intel Pentium Silver Jasper Lake mobile N6005 processor which has 4 cores and 4 threads and can boost to 3.3 GHz and also includes Intel UHD Graphics. The processor, and nearly the entire motherboard, is covered by a large metal heat sink: The front of the […]

Making a DIY Raspberry Pi camera mount with privacy mode!

XYLITOL Raspberry Pi Camera Mount

I’ve just repurposed an empty XYLITOL gum bottle into a DIY camera mount for the Raspberry Pi Camera Module 3 with privacy mode to boot… In order to avoid confusion, while Xylitol is a chemical compound, it’s also a Japanese brand of chewing gums (Lotte XYLITOL) that is sold in Thailand and other countries. I’m specifically talking about the latter in this post. Raspberry Pi Trading has just sent me a bunch of Raspberry Pi Camera Modules 3 for review, and since I don’t have any camera mount I initially thought maybe I’ll laser cut some mount or use some LEGOs as I did with the e-CAM20_CURB camera for Raspberry Pi 4. But then I saw some empty XYLITOL gum bottles, noticed the cap would open vertically, and it seemed like the modules might fit in there as well. And indeed they do with the Raspberry Pi camera modules snugged […]

Review of Creality Ender-3 S1 Pro 2-in-1 3D printer & laser engraver – Part 1: Unboxing and assembly

Ender-3 S1 Pro 3D printer converted into a laser engraver

Creality Ender-3 S1 Pro is a 3D printer that can be converted into a laser engraver thanks to a choice of 1.6W, 5W, and 10W laser modules, making it in theory a space-saving machine that can print 3D objects and engrave & cut materials. The company sent me a full kit with a 10W laser module, so after looking at the 3D printer’s specifications, I’ll check the various packages, and report my experience assembling the 3D printer, and then converting it into a laser engraver in this article, before actually testing both functions in the second part of the review. Since Karl reviewed the Ender-3 Pro 3D printer over two years ago, I asked about the difference and was told the new model got various improvements such as a direct extruder, CR-Touch auto bed-leveling, and support for high-temperature printing. Creality Ender-3 S1 Pro specifications Technology – FDM Maximum printing volume […]

Adding an external serial console port to NanoPi R6S

NanoPi R6S DIY external UART console

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

Elecrow CrowBot BOLT & Game Controller Assembled

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 […]

Brume 2 router review with WireGuard, OpenVPN, Tor, and Adguard Home

Brume 2 review

We started the review of GL.inet GL-MT2500A security gateway, aka Brume 2, with an unboxing and teardown, and I’ve now had time to test the router in more detail so I’ll report my experience using the router with OpenVPN and WireGuard VPN, Tor, Adguard Home, and more. In a nutshell, it’s super easy to use, unless your ISP causes troubles, which it did in this case. Brume 2 connection and initial setup I connected the WAN port of the Brume 2 router to 3BB’s modem router (3BB is an ISP in Thailand), the LAN port to my laptop, and finally the USB-C power supply (power draws is 2.3 Watts at idle). Let’s now go to the dashboard using the default IP (192.168.8.1). This will take us through the configuration wizard to select the language and set up the admin password. I was then immediately greeted by an “Upgrade Reminder” and […]

Getting started with e-CAM20_CURB camera for Raspberry Pi 4

eCAM20_CURB night scene

e-con Systems e-CAM20_CURB is a 2.3 MP fixed focus global shutter color camera designed for the Raspberry Pi 4, and the company has sent us a sample for evaluation and review. We’ll start by providing specifications, before checking out the package content, connecting the camera to the Raspberry Pi 4 with a DIY LEGO mount, showing how to access the resources for the camera, and trying tools provided in the Raspberry Pi OS or Yocto Linux image. e-CAM20_CURB specifications The camera is comprised of two boards with the following specifications: eCAM217_CUMI0234_MOD full HD color camera with 4-lane MIPI CSI-2 interface ON Semiconductor AR0234CS CMOS sensor with 1/2.6″ optical form-factor Global Shutter Onboard ISPimage sensor from ON Semiconductor Uncompressed UYVY streaming HD (1280 x 720) up to 120 fps Full HD (1920 x 1080) up to 65 fps 2.3 MP (1920 x 1200) up to 60 fps External Hardware Trigger Input […]
