Betavolt BV100 3V nuclear battery aims to deliver 100 microwatts for over 50 years

Btavolt BV100 is a nuclear battery that never needs to be charged and designed to output 3V/100µW (microwatts) for over 50 years for the aerospace industry, AI equipment, medical devices, MEMS systems, advanced sensors, small drones, and micro-robots. At 15x15x5mm, the 50-year nuclear battery is fairly small although 100 microwatts is not a lot of power… That’s only the first step, however, as the Chinese company plans to launch a 1W nuclear battery, and says that if (government) policies allow, nuclear batteries should eventually enable smartphones that never need to be charged and forever fly drones… How does that all work? First, as Betavolt states in its press release (in Chinese), it’s not exactly new technical as in the 1960’s, the US and the USSR used betavoltaic batteries for the space programs. But those were relatively large and heavy, operated at high temperatures, and were expensive. Wikipedia mentions that one […]

GL.iNet Flint 2 router review – Part 2: WiFi 6, 2.5GbE, WireGuard performance

In the first part of the review of the GL.iNet GL-MT6000 “Flint 2” WiFi 6 router, I had a look at the package content and the hardware design with a teardown of the router, and quickly tried it out. I’ve now had more time to play with the router focusing the review on WiFi 6 and 2.5GbE performance, and checking whether of 900 Mbps Wireguard VPN claim had any truth to it. The router also supports the Tor network to anonymously browse the web, Adguard Home to get rid of unwanted ads, and Repeater mode among other features. Those all work with the Fliont 2 router, but I won’t cover those in detail here, and invite you to check out the GL.iNet Brume 2 security gateway review for Tor and Adguard Home and the GL.iNet Beryl AX review for the repeater mode test.

How I “fixed” the display on Lichee Console 4A terminal

When I wrote a hands-on post about Lichee Console 4A RISC-V development terminal I noted the display would sometimes have strange effects or simply go black. I’ve now fixed the issue, and I was just probably unlucky since the issue must be rare, but I’ll still document it in case somebody encounters a similar problem and for fun! First, the video below shows what I would see on my terminal after using it for a few minutes. Since then, the display has gone completely dark, and all I see is the backlight, but I can still access the device through an SSH terminal. It looks like a bad connection issue, but I still contacted Sipeed and they told me it must have been the display connector. So I turned off the device and reopened the enclosure to remove and reinsert the cable for the display as shown in the photo […]

MINIX NEO Z100-0dB fanless N100 mini PC review – Part 1: Unboxing, teardown, and first boot

MINIX Z100-0dB (or MINIX NEO Z100-0dB) is a fanless mini PC powered by the popular Intel Processor N100 quad-core Alder Lake-N CPU with up to 32GB RAM, up to 512GB M.2 SSD, various USB 3.2/2.0 ports, a microSD card slot, two HDMI 2.0 ports, and a 2.5GbE RJ45 jack, as well as WiFi 6 and Bluetooth 5.2 wireless module. MINIX sent us a sample of the NEO Z100-0dB mini PC for review with 16GB DDR4-3200 RAM and a 512GB M.2 SSD preloaded with Windows 11 Pro. Since we’ve already listed the specifications in the announcement, today, we’ll go through an unboxing and a teardown before giving it a quick try booting Windows 11 Pro. We will then test the performance and features of the mini PC in detail with Windows 11 Pro and Ubuntu 22.04 (or 24.04) in the next parts of the review in several weeks. MINIX NEO […]

OpenWrt One/AP-24.XY is an upcoming router board developed by OpenWrt and Banana Pi

OpenWrt developers have started the process to develop the “OpenWrt One/AP-24.XY” router board based on MediaTek MT7981B (Filogic 820) SoC and MediaTek MT7976C dual-band WiFi 6 chipset, and designed in collaboration with Banana Pi that will also handle manufacturing and distribution of the router board. As of the OpenWrt 23.05 release, close to 1,800 routers and other devices are officially supported by the lightweight embedded Linux operating system, and many more claim to be running OpenWrt through a fork of the OS. But none of those are made by OpenWrt developers who have now decided to create their own router board in collaboration with Banana Pi since they’ve done such boards including the BPI-R4 WiFi 7 router SBC. OpenWrt One/AP-24.XY preliminary specifications: SoC – MediaTek MT7981B (Filogic 820) dual-core Cortex-A53 processor @ 1.3 GHz System Memory – 1GB DDR4 Storage 128 MB SPI NAND flash for U-boot and Linux 4 […]

Reolink Argus PT Ultra review – A solar powered 4K WiFi Pan-and-Tilt smart security camera

Reolink Argus PT Ultra Solar Panel Instllation

Nearly four years ago, I reviewed the solar-powered Reolink Argus PT pan-and-tilt security camera. The device worked (and still works) mostly fine, but it was at a time when security cameras did not implement AI features like people and vehicle detection just yet relying only on PIR motion sensors so I’d get plenty of false positives. The WiFi connection is not overly reliable either especially when I tried to access the camera from outside my house, something that does not happen with the PoE and 4G LTE models from the company. Reolink asked me whether I wanted to review the new Reolink Argus PT Ultra security camera with higher 4K resolution, dual-band WiFi support, as well as people, vehicle, and pet detection, and most of the same other features found on the older Argus PT. So I took up on the offer and I’ve used it for about one month […]
