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 […]

Easythreed NANO Mini Fully Assembled 3D Printer Sells for $160

If you plan on getting started with 3D printing, you’ll already find some decent low cost 3D printers on the market such as Anet A8 that is now selling for around $150 plus shipping. However, most of those come in kits that you need to assemble yourself, and some people may feel uneasy about the process. But this morning, I’ve come across another option with Easythreed NANO Mini 3D printer that is fully assembly, and up for pre-order on Banggood for $159.99 including free shipping.. Easythreed NANO Mini 3D printer specifications: Print Technology – FDM Print Size – 90 x 110 x 110 mm Nozzle Diameter – 0.4mm Layer Thickness – 0.1-0.3mm Filament Support – PLA Filament Size – 1.75mm Rotary technology – Belt drive, linear bearing technology Print accuracy – 0.1-0.3mm Feed Technology – Proximal feed Nozzle Temperature – 180-230℃ Printing speed – 10-20MM/S File format – Input: .Stl, Transfer: .gcode One key printing technology Storage – micro USB card USB – 1x USB port Power supply – Input: 110~240V 50/60HZ Output: 12V, 60W Dimensions – 188 […]

$9 SQ8 may be the World’s Smallest Car Dash Camera / Action Camera

There are so many car dash DVRs and action cameras on the market that barely differentiate themselves on the market that I don’t usually write about those anymore. But SQ8 “mini car video recorder full HD sports DV camera” caught my eye First, because at $8.99 on GeekBuying it’s really cheap, but most importantly because it’s incredibly tiny, even smaller than JeVois computer vision camera I reviewed last year. SQ8 camera specifications: Chipset – “AnGuo” Storage – micro SD card up to 32 GB Camera 12MP CMOS image sensor for 1080p30 videos (AVI/MJPG) 65 Degrees Wide Angle 3mm lens Motion Detection, Night Vision Audio – Built-in microphone/speacker (AAC) USB – 1x mini USB port Misc – On/off and mode buttons, reset pinhole, LED indicator Battery – 200 mAh good for about 100 minutes Dimensions – 2.2 x 2.2 x 2.0 cm Weight – 25 grams Operating Temperature – 0 – 60 […]

LiveStream #1 – Migrating to Marlin Firmware

Karl here. I’ve decided to start doing a weekly Livestream on different topics related to subjects covered on CNX Software. For the fist livestream, I will be showing the workflow that I use to migrate to newer Marlin firmware on HE3D K280 3D printer but it applies to any printer. I will also cover the calibration process for the K280. I originally did a written review of the K280 but it is sometimes hard to show concepts in writing. The livestream will take place on June 14th @ 21:30 ET timezone, and if you are interested you can register below, or come back to this page to check it out. Karl JohnsonKarl is a technology enthusiast that contributes reviews of TV boxes, 3D printers, and other gadgets for makers.

Unihertz Atom is an Android 8.1 Phone with a Tiny 2.4″ Display (Crowdfunding)

What we used to call phablet – smartphones with 5″ to 6″ display – are now simply called smartphones, as most companies now offer smartphones with larger displays since they are better suited for tasks like web browsing. Unihertz has gone the other way by launching Atom, an Android 8.1 smartphone with a tiny 2.4″ display. Demand does exist for such Phone, as while the Kickstarter campaign started a couple of days ago, the company has already raised close to $700,000 from around 3,000 backers. The “Atom” name clearly infringes on Intel’s trademark, so the model name is likely to change in a few days as has happened for “Atomwear” and “Nerdonic Atom X1“, but this did not affect the campaigns after they changed the names. Unihertz Atom smartphone specifications: SoC- Unnamed octa-core processor clocked at up to 2.0 GHz System Memory – 4GB RAM Storage – 64GB internal storage […]
