Genmitsu CNC 3018-PRO CNC Router Review – Part 1: Build & First Etches

Sainsmart 3018 CNC Router

Hey Karl here. Today we are going to look at something a little different. I am writing about my experiences with building Genmitsu 3018 CNC router upgraded version provided by Sainsmart for this review. While waiting on the unit to arrive I did some research and found that there are several different versions on the market labeled CNC xxxx. The xxxx represent the build volume in the x and y. So the one I was sent has a 300x180mm build volume. The 3018 is called upgraded because the new mounting for the X and Y rods and lead screws. On the previous version these had to be mounted and manually aligned which from what I read can be a pain. Building Genmitsu CNC 3018-PRO CNC Router The build went very well. The 3018 user manual was mostly pictures but they called out anything that might be questionable. I had been talking about the CNC/engraver with my kids and they were …

WisCellular Certified Global LTE IoT Arduino Shield Enters Beta Testing

WisCellular

RAK Wireless introduced WisLTE Arduino shield last year based on Quectel BG96 module with support for NB-IoT (Cat NB1), eMTC (Cat M1), and 2G fallback as well as GPS location. WisLTE worked globally, but the company did not go through the certification process, at least not for the global market, meaning the shield could not be used in commercial application. That’s why Rak Wireless has been working on WisCellular shield, also based on Quectel BG96, but this time with global certification. WisCellular specifications: Cellular Module – Quectel BG96 (based on Qualcomm MDM9206) Cellular Network 2G/GSM (GPRS/EPGRS) 4G/LTE-M (Cat M1) NB-IoT (Cat NB1) Global Bands EDGE/EGPRS: 850/900/1800/1900MHz LTE FDD: B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B26/B28 LTE TDD: B39 (For Cat M1 Only) Data Rate Cat M1: Max. 300Kbps (DL), Max. 375Kbps (UL) Cat NB1: Max. 32Kbps (DL), Max. 70Kbps (UL) EDGE: Max. 296Kbps (DL), Max. 236.8Kbps (UL) GPRS: Max. 107Kbps (DL), Max. 85.6Kbps (UL) Voice – VoLTE (Cat M1 Only) SMS – Point-to-point MO and MT, …

AV1 Video Samples Now Available on YouTube & Netflix

Youtube AV1 Video

We first covered AV1 royalty-free, open source video codec in 2016, which with backing from companies like Google, Amazon, Intel, Microsoft, and many others with the aim to compete with H.265, and lower the cost of delivering video both thanks to a better compression ratio, and the lack of royalties. Since then progress has been made, with AV1 specifications released last March, and now both YouTube and Netflix are offering some beta AV1 video samples for testing. If you want to play some videos in AV1 format in YouTube as I did in the screenshot above, you’d need to install a very recent (beta) version of Chrome or Firefox, follow the other instructions as explained in YouTube’s AV1 beta playlist: Support for AV1 in MP4 within Media Source is available in Chrome 70, and Firefox 63 builds newer than September 13 with the media.av1.enabled pref set.

Intel Gemini Lake processors and associated have been products  available for several months, and although I’ve published several Gemini Lake reviews, those were courtesy of Linuxium, which means MINIX NEO J50C-4 is my very first Gemini Lake mini PC.

RockPro64 RK3399 Board Linux Review with Ubuntu 18.04 + LXDE

RockPro64 Heatsink Ports

Let’s do one more RK3399 Linux review using Pine64 RockPro64 development board. After shortly checking out the hardware, I’ll test Ubuntu 18.04 “Bionic” LXDE on the board, test 3D graphics acceleration, video playback, USB storage and network performance among other things on the board. RockPro64 Board Unboxing The board came in a cardboard package, and the sticker made it clear I had received the 2GB LPDDR4 version. Even after FriendlyELEC NanoPi M4 announcement, Rockchip ROCKPro64 is still the cheapest RK3399 development board around, so it should come as no surprise that the board does not come with any accessories by default. Another way to keep the price low was not to include any built-in storage apart from SPI flash, so instead most people will either boot from micro SD card or an eMMC flash module both of which need to be purchase separately. Another cost-saving is the lack of built-in wireless module for WiFi and/or Bluetooth connectivity, which makes sense …

Arduino Releases Command Line Interface (CLI) Alpha Preview

arduino-cli

So far, AFAIK the only official ways to program Arduino boards were through the Arduino IDE program, or the cloud-based Arduino Create which works in your web browser and does not require any installation on your computer. While graphical interfaces are nice and user-friendly, many of us are more productive while working using the command line,  especially if commands can be scripted. So Arduino decided to work on a command line interface (CLI) for professional users, and have just announced a preview release. arduino-cli works in Windows, Linux, and Mac OS, and allows you install libraries, boards, and cores (e.g. esp32 Arduino core), compile the code, and upload the binary to the target board. If you want to get started quickly, you can download the binary “alpha” releases in the announcement board, but instead I opted to build the client myself as explained on Github. Everything below is done in Ubuntu 18.04. I don’t have a board handy right now, …
