My Experience with Dodocool AC750 WiFi Repeater

Tweet A while ago, I tested Dodocool DC30S USB type C Hub with HDMI, USB port, and a card reader, and recently the company asked me whether I wanted to review another of their accessories. My ISP has recently taken the habit of being down several hours each month, so I rely on my neighbor’s WiFi (with he’s permission) in those case, but since the signal is too weak, I’m using a wireless audio streamer and a power bank to extend the signal and connect it to my router using WDS Bridging.  Then I saw Dodocool DC24 802.11ac WiFi repeater, so I decided to give it a chance. Dodocool DC24 A750 Repeater Unboxing I received the device is a cardboard box with some specifications. It’s an AC750 router/repeater with 300 Mbps @ 2.4 GHz + 433 Mbps @ 5 GHz. The product page linked above has some more details with the Ethernet port being Fast Ethernet (10/100M), and the solution …

WeLoop Hey 3S Sports Smartwatch Review – Part 2: GPS, Running, Cycling, Notifications, and More

Tweet As mentioned previously I did not have such good luck with smart wearables so far, with disappointing products often with a short lifetime (a few weeks to a few months, and some design issues here and there like an e-Paper display without backlight, a touchscreen display with poor locking mechanism (so it’s activated while taking a shower), unreliable heart rate monitor, poor waterproofness and so on… My main requirements are always-on display, battery life as long as possible, notification support, good waterproofness to do tasks like taking shower or swim without having to remember to remove the watch, among others less important requirements. I mostly gave up on the category for about year, but decided to give it a try when GeekBuying asked me if I was interested in reviewing WeLoop Hey 3S sports smartwatch.  Maybe things have improved since then. I’ve already gone through unboxing and initial setup in the first part of the review entitled “WeLoop Hey …

WeLoop Hey 3S Sports Smartwatch Review – Part 1: Specifications, Unboxing, First Try with Android App(s)

Tweet It’s been a while since I have reviewed a smartwatch or fitness tracker, simply because I found most devices to be lacking, and break easily after a few weeks or months. It’s also difficult to find a device that combines long battery life, waterproofness, a decent screen, and all that at a reasonable price. But I decided to give it another try when Geekbuying asked me whether I was interested in reviewing WeLoop Hey 3S sports smartwatch with 5 ATM waterproofness,  a standby time of 30 days,  a color display, an optical HRM, and built-in GPS.  I’ve just received it , so I’ll start by posting specifications about the watch, and checkout what’s inside the package. Weloop Hey 3S Specifications Display – 1.28″ color memory LCD display with 176×176 resolution, touchscreen Connectivity – Bluetooth 4.0 LE, built-in GPS Sensors – Heart rate monitor Battery – 270 mAh LiPo battery good for over 30 days in standby, around 7 days …

Intel NUC7CJYSAL “June Canyon” Gemini Lake NUC Mini PC Review with Windows 10 and Ubuntu

Tweet The hardware specification for mini PCs has recently evolved past the traditional fixed amount of memory and storage. Now mini PCs are shipping with SODIMM slots allowing RAM expansion and a variety of M.2 or SSD combos providing flexible storage options. Recent mini PCs are also coming to market with desktop processors rather than mobile processors because there has been a gradual acceptance of the necessary inclusion of a small internal fan. In doing so not only is this addressing the key limiting factors for mini PCs but it is also redefines the very definition of a mini PC. Until recently Intel NUCs (Next Unit of Computing) were seen as small-form-factor personal computers primarily because they consisted of the traditional motherboard with a processor, included removable RAM and storage and were enclosed in a case with an external power supply. They were also sold as kits meaning they were essentially the ‘barebones’ ready to be build with separately purchased …

Raiscube A8R 3D Printer Review

Tweet Hello Karl here with a look at the Raiscube A8R. If you recall I reviewed the R2 3D printer quite a while ago. I really liked the R2, so when I heard that this newer version came out I reached out to Raiscube directly and asked for a review sample. Raiscube kindly obliged, and I am so glad that they did. The A8R is the upgraded version to the R2. The most prominent differences is the acrylic frame is gone, being replaced with an aluminum frame, and the build time is slashed considerably. Build Volume: 210 x 210 x 225mm Material diameter: 1.75mm Direct Drive Extruder Dual Z 12V/25A power supply Up to 95°C on the bed Up to 250°C on the nozzle Ramps Plus2 Board v1.8.26 Educational Opportunity This review has been in the works since last November. I liked it a lot so wanted to put it through its paces and put a lot of hours on …

Onda V18 Pro Tablet Review – Part 2: Android 7.1 Firmware

Tweet Onda V18 Pro is one of the first tablet powered by Allwinner A63 processor allowing for low-cost tablets with high resolution 2K displays (2560×1600). I received a sample from GearBest, and I already checked out the hardware and run Antutu 7 benchmark in the first part of the review entitled “Onda V18 Pro (Allwinner A63) 2K Tablet Review – Part 1: Unboxing, First Boot, and Antutu 7 Benchmark“. I’ve now spent more time with the tablet browsing the web, watching YouTube videos, reading books, playing games, and running some more benchmarks, so I’ll report my findings in this second part of the review. General Impressions I’ve found the tablet’s high resolution 10.1″ display to be very good for reading books or browsing the web, albeit the latter feels a bit slower than on Xiaomi Mi A1 smartphone (my main phone). As we’ll see later on, 3D graphics is not that good, so some games that work fin on my …

A First Look at ESP32-LyraTD-MSC Audio Mic HDK with Baidu DuerOS Assistant

Tweet Earlier this year, Espressif Systems had unveiled their ESP32-LyraTD-MSC Audio MiC HDK (Hardware Development Kit) which features an ESP32-WROOM module, a 4-mic array DSP, 3 microphones, an audio jack, and various I/Os. I received the board a couple of weeks ago, and while there’s no public information released yet, the company provided me with ESP32-LyraTD-MSC User Guide in English. Eventually, I’d expect Google Assistant and Amazon Alexa to be supported, but in the meantime I had to leverage my (lowly) Chinese language skills to get started since the kit is pre-loaded with firmware connecting to Baidu DuerOS voice assistant. ESP32-LyraTD-MSC Unboxing The kit came in a bland Espressif Systems carton box. Inside the package, I could only find one kit comprised of two boards. The bottom board read ESP32_MicrosemiDSP_Mainboard-V1, and does not show much apart from marking for connectors, headers and the power switch. While the top comes with eight buttons (Vol +, Vol -, Mode, Boot, RST, Rec, …
