YouTube Streams 1 & 2 Update, Plus Quick Fix for Uneven X Gantry

Hey Karl here with an update on the YouTube Live streams from last week. Live Streams Update The 1st stream went about as well as I expected….Not very well. I was really nervous and I broke the live link that was posted on here at the last minute. My whole reasoning for the Livestream was to show the processes in real time and not do too much footwork ahead of time. On the first one I was planning on migrating from Marlin 1.1.6 to Marlin 1.1.8 but I had already done lol… So I ended up migrating to the bugfix branch which presented additional challenges. Overall it was successful and I hope I conveyed the process. I was able to get it to print but I ended up going back to 1.1.8 due to some error in the bugfix branch that caused weird jittery movement. I will in the future […]

Dual Display Laptop Made Possible with DUO Add-on Display (Crowdfunding)

I’m using a dual monitor setup at home since it’s just more convenient and increases productivity, but when I’m on the go, I have to revert to the single screen on my laptop. The guys at Mobile Pixels decided it was not good enough, and worked on providing a solution that allows you to take that dual display setup on the go. This gave birth to DUO, a screen that attaches to the back of your laptop, and that you can slide to the left or right of your laptop’s screen to add another display whether you may happen to be. DUO display specifications: Display Size & Resolution – 12.5″, 1920×1080 pixels Rotation – 270º full rotation, 180° presentation mode Connection – USB type C for power and video signal Power Consumption – 1.6 Watts; 0.3W in “rest mode”. Dimensions – 32.5 x 21.8 x 1.2 cm (ABS plastic) Weight […]

ESP8266 RGB LED Strip Control with ANAVI Light Controller, Arduino, MQTT, and HTML5

Anavi-Light-Controller-Starter-Kit-Assembly

A few months ago I reviewed ANAVI Light pHat for Raspberry Pi which allows you to control an LED RGB strip from the popular development board. However, if all you need is to switch the RGB LED light on and off, or change the color, the hardware is clearly overpowered for the tasks. So Leon ANAVI designed another board based on ESP8266 – ANAVI Light Controller – which does the same thing with lower cost and more power efficient hardware. Leon sent me a sample for review, so let’s see what we’ve got. ANAVI Light Controller Starter Kit Unboxing I received a package for the Starter kit that’s offered for $39 on CrowdSupply. We’ve got the main board, a USB debugging, an acrylic enclosure with screws and spacers, a one meter RGB LED strip, and some stickers inside the package. If we have a close look at the board we […]

Allwinner T7 Automotive SoC Complies with AEC-Q100 Grade 3 Specifications

Allwinner T-series processors such as Allwinner T2 are designed for the transportation / automotive market for products like smart rear-view mirrors, infotainment systems, and navigation systems. While the company’s offered wide-temperature range support, AFAIK they did not have a part that had an actual automotive certification so far. This changes with their Allwinner T7 processor which is said to be the first Chinese processor achieving AEC-Q100 Grade 3 qualification. AEC-Q100 is a “failure mechanism based stress test qualification for integrated circuits” brought out by the Automotive Electronics Council. The chip must pass various tests within their specified temperature range (grade): Grade 0: -40°C to +150°C ambient operating temperature range Grade 1: -40°C to +125°C ambient operating temperature range Grade 2: -40°C to +105°C ambient operating temperature range Grade 3: -40°C to +85°C ambient operating temperature range Grade 4: 0°C to +70°C ambient operating temperature range Allwinner T7 comes with an […]

Xilinx Zynq-7020 based PYNQ-Z1 Arm + FPGA Board is Meant to be Programmed with Python

Xilinx Zynq-7000 series is a family of SoC based on Arm Cortex A9 processor coupled with FPGA fabric, and since the introduction in 2012, we’ve seen may board based on the entry-level Zynq-7010 or Zynq-7020 SoCs. Digilent PYNQ-Z1 is another Xilinx Zynq board from the company, but it does not differentiate itself by its hardware features, and instead the software part is the most interesting. The board is designed to be used with PYNQ, a new open-source framework that enables embedded programmers to exploit the capabilities of Xilinx Zynq SoCs without having to design programmable logic circuits, relying instead on Python programming. Digilent PYNQ-Z1 hardware specifications: SoC – Xilinx Zynq-7020 (XC7Z020-1CLG400C) dual core Arm Cortex-A9 processor with FPGA with 1.3 M reconfigurable gates System Memory – 512MB DDR3 Storage – Micro SD card slot, 16MB QSPI Flash with factory programmed globally unique identifier (48-bit EUI-48/64 compatible). Video – HDMI In […]
