Review of Koogeek BP2 Bluetooth Blood Pressure Monitor

Koogeek BP2 is an FDA approved smart blood pressure monitor that connects over Bluetooth to your Android or iOS smartphone, or WiFi to the cloud. The company sent me a sample for evaluation, so let’s get started right away. Koogeek BP2 Unboxing The device is sent in a cardboard package with Koogeek brand… and some more derails about the specifications on the bottom of the package. I asked the company to confirm about FDA approval, and they told me to look for K134029 on the FDA website, which lead me to this document testing Shenzhen Belter Health Management and Analysis ePA-46B, and comparing it to the results of Omron HEM-7200-Z (BP742) with the conclusion being that: The Belter Blood pressure meter (ePA-46B) is substantially equivalent to the predicate devices. Koogeek BP2 is the same as Belter ePA-46B, but just rebranded, and with a different mobile app. In the package will find […]

Review of Sonoff RF Bridge, Sonoff 4ch Pro, and Sonoff POW with Sonoff-Tasmota Firmware

Karl here. Today we are going to look at 2 new and one older Sonoff devices. Sonoff RF Bridge – $9.90 433MHz RF to WiFi Bridge Sonoff 4ch Pro – 4 Gang WiFi RF Smart Switch Sonoff POW – Wireless switch with power metering capabilities I spent very little time with the stock firmware on the device. I don’t like the fact that an Internet connection is needed, and I am not in control. As of the time of this writing I found the Ewelink was not configurable enough to meet my needs. There is one feature that is really nice that I could easily see keeping stock firmware. It is the Alexa Skill. It worked. I am also currently reviewing Vobot Smart Alarm Clock with Alexa integration and had no trouble controlling the Sonoff devices with Alexa. But unfortunately I am lazy and want everything automatic so I can’t […]

Getting Started with Espruino & JavaScript on ESP32 with ESPino32 Board

Venus Supply Co., Ltd, better known as ThaiEasyElec, is a company based in Thailand, selling embedded systems and development board, as well as providing development services based in Thailand. The company sent me their latest board called ESPino32 powered by Espressif ESP-WROOM-32 WiFi and Bluetooth module for evaluation. While the board is supported in Arduino-esp32, I’ve already tested Arduino with ESP32-Bit module & ESP32-T board, so after checking out the hardware, I’ll load it with something different: Espruino, a firmware allowing for JavaScript programming over the serial console, or a Web based IDE. ESPino32 Unboxing and Soldering The board shipped with four female headers, and I/O stickers. The board includes ESP-WROOM-32, exposes I/Os through four 10-pin headers, features CP2104 chip for serial to USB debugging via micro USB port, two buttons (reset and program), a user LED connected to IO16, and a jumper to select between regulated power supply (micro […]

MINIX NEO Z83-4 Pro Mini PC Review – Part 2: Windows 10 Pro

MINIX launched NEO Z83-4 Cherry Trail mini PC last year, but the company has now launched NEO Z83-4 Pro, an updated version with a slightly faster Atom X5-Z8350 processor, Windows 10 Pro (instead of Home), and a a VESA mount kit. I’ve already checked the hardware in the first part of the review, so today I’ll report my experience with Windows 10 Pro. Windows 10 Home vs Windows 10 Pro My main computer runs Ubuntu 16.04, and I’m only using Windows 10 during reviews… But so far all other mini PCs I tried came with Windows 10 Home, and NEO Z83-4 Pro is my first Windows 10 Pro computer. So I had to educate myself, and Microsoft website has a comparison between the two versions of Windows 10. Windows 10 Pro supports all features of Windows 10 Home, plus the following: Security Windows Information Protection – Formerly Enterprise Data Protection […]

2017 Tevo Tarantula Dual Extruder 3D Printer Review – Part 2: Auto-Leveling, Dual Color Prints, Flex Filament

Karl here with final part of Tevo Tarantula dual extruder 3D printer review. The kit that was sent by Gearbest has a large bed, auto leveling, dual extrusion, and flex extruder of which I only found the flex extruder appealing to me. I have had this printer for a while now. It was relatively easy to setup, but near the end of the build it did not cover every aspect. There are lots of videos and a big Facebook group if you run into any troubles. Overall it is a good printer, but some of the features I initially thought I would like turned out to not be very useful. Auto leveling I tried my hardest to get this to work even going as far as to upgrade the firmware, but because they had a printed bracket on it, it drooped on my first high temp ABS print. I removed […]

A First Look at ESP32 PICO Core Development Board Powered by ESP32-PICO-D4 SiP

Last week, I wrote about ESP32-PICO-D4 system-in-package (SiP) that contains ESP32 WiSoC, 4MP SPI flash, a crystal oscilloscator and some passive components in a single 7×7 mm package in order to allow smaller designs based on ESP32. The company noticed the post, and asked me whether I’d be interested in receiving “some development boards based on ESP32 PICO”, an offer hard to refuse :), and within a couple of days I received the package below. So I ended up with 10 identical development kits, the company probably thought it was no worth paying for DHL to only send one or two development boards… The boards may also be part of some contests… We’ll see 😉 So let’s take two, and have a closer look at “ESP32_PICO_Core_Board_V3″… It comes with two rows of 20 pins with access to all I/Os, and features three main chips: ESP32-PICO-D4 SiP, AMS1117 voltage regulator, and Silabs […]

Zidoo X7 Review – Part 2: Android 7.1 Firmware, ZDMC, WiFi, and More

Zidoo X7 is an Android TV box powered by Rockchip RK3328 processor similar to Bqeel MVR9 with 2GB RAM, but instead of provide Gigabit Ethernet, and 802.11 b/g/n WiFi, it comes with Fast Ethernet, and 802.11 b/g/n/ac WiFi, so is better suited to people using WiFi instead of Ethernet for media streaming. You’ll find plenty of photos in the first part of the review entitled “Zidoo X7 TV Box Review – Part 1: Unboxing & Teardown“, and I’ll report my experience with Android 7.1.2 firmware in this second part. First Boot, Setup, and First Impressions I connected two RF dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad via a USB hub, a USB keyboard to take screenshot, and a Seagate USB 3.0 hard drive to the single USB 3.0 port on the box. I perform tests with Ethernet in most reviews, but with Zidoo X7, […]

Testing KingDian N480 240 GB M.2 SSD in MeLE PCG03 Apo Mini PC

MeLE PCG03 Apo Apollo Lake mini PC supports M.2 80mm SSD’s, but at the time of the review I did not have such accessories, so I only tested the computer with its 32GB eMMC flash and external USB drives. I’ve now received Kingdian N480 240GB SSD courtesy of GearBest, so I’ll install it in the mini PC, test it in Windows 10, and install Ubuntu 16.04. KingDian N420 M.2 SSD Hardware Installation I’ve received a big carton box for the SSD, but finally the retail package is minimal. You’ll find the SSD and a screws in the package. You’ll note the device supports both M.2 Key B and Key M sockets. I’ve already explained how to open MeLE PCG03 Apo, basically loosen 6 screws, and then I just had to insert the SSD with the right orientation (check the 4 / 5 pins on each side), and use the screw […]
