HE3D K280 3D Printer Review – Part 1: Build, Tweaks, and First Prints

Hello Karl here again with another 3D printer review. Today we are looking at an HE3D K280. I saw the brand for the first time on Gearbest a couple months ago and asked for it to review. I never heard of this brand before and have been wanting to review a delta style printer. In my case, I should have been careful what I asked for. It took me quite some time to get it to print utilizing the whole print bed. I experienced several challenges and after defeating them I enjoy this printer quite a bit. Delta style printers mesmerize me with the movements that they make and all the math that goes into moving the extruder in the X, Y and Z. Regular Cartesian printers are rather simple in this respect. Build Volume – 280×600 mm Heated bed No Parts cooling 2020 aluminum and all injected molded parts […]

MatchBox LoRaWan Gateway Review – Part 1: Unboxing and Teardown

Last spring, I wrote about MatchX.io MatchBox LoRaWAN gateway with GPS, WiFi, and Ethernet connectivity. The gateway is equipped based on a Mediatek WiFi module running Linux (OpenWrt/LEDE), Semtech chips for the LoRa part, and support up to 65,535 nodes, such as the as well as MatchStick, MatchModule, and MatchCore sensors provided by the company. I’ve just received MatchBox gateway for review, but I’m still waiting for 920-925MHz LoRa nodes as they are going through the FCC certification process, and I also have to wait for clarifications regarding local regulations. So in the meantime, I’ll check out the gateway hardware. MatchBox LoRaWAN Gateway Unboxing The gateway is shipped with a power supply, power cord, two antennas, an installation guide,… as well as three screws and pegs to wall mount the gateway and power supply, and in case you want to install the gateway on a pole, as shown below, for […]

Mozilla Adds HTML5 AV1 Video Support to Firefox 59 Nightly Builds

Last year, we wrote about AV1 royalty-free open source video codec managed by the Alliance for Open Media (AOMedia), a non-profit organization with members such as Amazon, Cisco, Google, Intel, Microsoft, Mozilla, and other companies. Eventually AV1 should be 25 to 35% more efficiency than H.265 or VP9, but encoding will be slower, and at the time, my AMD FX8350 based computer could encode CIF (352×288) video at less than 0.5 fps, and I had to use command line tools to encode and decode/playback the videos. But thing are progressing nicely, and it’s now possible to stream AV1 video with HTML5 / in Firefox 59.0 (nightly) using Bitmovin Player. If you are using Ubuntu, you can also install Firefox nightly as follow:

sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa
sudo apt-get update
sudo apt-get install firefox-trunk

sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa

sudo apt-get update

sudo apt-get install firefox-trunk

Start it and visit the demo page to stream an AV1 MPEG-DASH/HLS stream in your web browser. It works from 360p @ 200 Kbps up to 720p […]

Review of ITEAD Studio IP66 Waterproof Case for Sonoff Wireless Switches (and Other Boards)

ITEAD Studio recently launched a waterproof enclosure for $2.90 (now at still a decent $3.90), rated IP66, for their family of Sonoff wireless switches, so you can safely use them outdoors protected from rain and dust. The company sent me one sample together with Sonoff RF switch supporting WiFi and 433MHz RF connectivity so that I can test the case, and write a review describing my experience. I’ll focus on the waterproof since this is the main focus of this review, and beside Sonoff RF, you can also use Sonoff basic, various other Sonoff boards (POW, TH10/T16), and even other development boards as we’ll seen below. I’ll be using the stock firmware with eWelink app, but if you prefer alternative firmware like ESPurna or Sonoff-Tasmota, you may want to flash it to your Sonoff now. The waterproog case has two parts, a rubber cord, two waterproof PG7 connectors, and four […]

JeVois-A33 Linux Computer Vision Camera Review – Part 2: Setup, Guided Tour, Documentation & Customization

Computer Vision, Artificial Intelligence, Machine Learning, etc.. are all terms we hear frequently those days. JeVois-A33 smart machine vision camera powered by Allwinner A33 quad core processor was launched last year on Indiegogo to bring such capabilities in a low power small form factor devices for example to use in robotics project. The company improved the software since the launch of the project, and has now sent me their tiny Linux camera developer kit for review, and I’ve already checked out the hardware and accessories in the first post. I’ve now had time to test the camera, and I’ll explained how to set it up, test some of the key features via the provided guided tour, and show how it’s possible to customize the camera to your needs with one example. Getting Started with JeVois-A33 In theory, you could just get started by inserting the micro SD card provided with […]

BBen MN10 TV Stick Review – Windows 10, Ubuntu 17.04, Benchmarks, and Kodi

The BBEN MN10 is the second Apollo Lake device to be released in the stick form-factor and on paper looks to have a lot to offer: It features an Apollo Lake N3350 SoC, an unusual 3GB of RAM, 64GB of storage and is cooled by a ‘mute’ fan. The devices comes in a plain box with a power adapter, and a leaflet style manual. It also included a three-pin UK power adapter, as this was advertised as the ‘BBen MN10 Mini PC – UK PLUG BLACK’. Looking at the detail specifications: We can immediately see discrepancies as the device does not have a ‘RJ45 Port Speed: 1000M LAN’ port, and was not supplied with ‘1 x HDMI Cable’ nor ‘1 x Remote Control’. Powering on the device and the ‘mute’ fan is also a miss-representation as it starts immediately and is noticeably noisy. It also runs at full speed regardless […]

Xiaomi Mi A1 Smartphone Review – Part 2: Android 7.1.2 Firmware

Google recently announced several Android One smartphones, which are supposed to get 2 years of firmware updates, including to the latest version of Android, such as HTC U11 Life and Android One Moto X4. Many of those phones are limited to some specific countries, but Xiaomi Mi A1 will be launched in over 40 countries, and thanks to Chinese online shops is really available worldwide. GearBest sent me the latter last month, and in the first part of Xiaomi Mi A1 review I simply went through unboxing, booted the phone, perform an OTA update, and ran Antutu 6.x on the phone for a quick estimate of performance. Since then, I’ve had around four weeks to play with the smartphone running Android 7.1.2 (still), so I’m ready to report my experience in the second part of the review. General Impressions In the past year, I used Vernee Apollo Lite smartphone powered […]

Tronxy X3S 3D Printer Review – Part 3: Upgrades to Fix Bed Leveling Issues (Permanently)

Karl here. I have had the Tronxy X3S 3D printer for a while now. It prints well but as I mentioned in previous articles I had to level for every print. Actually near the end I would just overpower the stepper motors while the skirt was printing and level. Leveling front to back was not affected. Only the z height. So this worked but it was frustrating. Before that I tried several different things to mitigate. I thought maybe the endstop for Z homing was inconsistent and replaced it. I tried heating the bed for extended period of time thinking that maybe some thermal expansion. Didn’t help. I finally did a major change to the X carriage with success. I even moved the printer to our local library and the bed stayed leveled for a demo. I call this a success, and will show how I did it. Inspiration for […]
