Sonoff Wireless Switch Family Gets a $3 IP66 Waterproof Enclosure

ESP8266 powered ITEAD Studio Sonoff wireless switches have been popular because they are inexpensive, highly customizable thanks to work from the community leading to open source projects such as ESPurna and Sonoff-Tasmota, and come fully packaged so you don’t need to make your own case for it. That works well for indoor projects, but if you needed to control outdoors lights, gate, water pump, etc… you had to protect the device from humidity/rain. That may not be necessary anymore as the company is now selling Sonoff Basic with an IP66 waterproof enclosure for $7.75, or the case only for $2.90.Sonoff waterproof case: Ingress Protection Rating – IP66 Material – PC V0 Dimensions – 132.2 x 68.7 x 50.1mm (See details) Weight – 145.0g IP66 rating is not suitable for prolonged immersion, but it should be good to protect against rain or high humidity. The box ships with two standardized PG7 […]

If you have really good memory, you may remember that Freescale was working on a 96Boards compliant i.MX 7 development board in 2015 that was supposed to be released in Q4 of that year. Yesterday the board was finally launched and demonstrated on 96Boards OpenHours. i.MX7-96 board (aka Meerkat) is powered by an NXP i.MX 7 dual core ARM Cortex-A7 + 1x Cortex M4 processor, coupled with 512MB RAM, and complies with the Consumer Edition (CE) of 96Boards specifications. iMX7 96 board specifications: SoC – NXP i.MX 7Dual dual ARM Cortex-A7 processor at 1.2 GHz, with Cortex-M4 @ 200 MHz and 2D accelerator System Memory – 512 MB DRAM Storage – micro SD slot Video Output – HDMI Connectivity – 802.11 b/g/n WiFi + Bluetooth 4.1 LE (LSR Sterling-LWB module) USB – 2x USB 2.0 hosts, 1x micro USB 2.0 OTG Camera – 1x MIPI-CSI Expansion Interfaces 40-pin low speed […]

Linux Benchmarks – Intel J3455 Apollo Lake vs Z3735F Bay Trail vs RK3399 and Other ARM Platforms

Since I’ve just installed Ubuntu 17.10 on MeLE PCG35 Apo, I decided I should also run some benchmarks comparing with other ARM and x86 Linux platforms I’ve tested in the past.I was particularly interested to compare the performance of Intel Apollo Lake processors (Celeron J3455 in this case) against higher end ARM processors like Rockchip RK3399 (2x A72, 4x A53) since systems have a similar price (~$150+), as well as against the older Bay Trail processor to see the progress achieved over the last 2 to 3 years. To do so, I used Phoronix Benchmark Suite against Videostrong VS-RK3399 results (RK3399 development board):

sudo apt install php-cli php-gd php-xml php-zip 
wget http://phoronix-test-suite.com/releases/repo/pts.debian/files/phoronix-test-suite_7.4.0_all.deb 
sudo dpkg -i phoronix-test-suite_7.4.0_all.deb
phoronix-test-suite benchmark 1709271-TY-1704029RI26

sudo apt install php-cli php-gd php-xml php-zip

wget http://phoronix-test-suite.com/releases/repo/pts.debian/files/phoronix-test-suite_7.4.0_all.deb

sudo dpkg -i phoronix-test-suite_7.4.0_all.deb

phoronix-test-suite benchmark 1709271-TY-1704029RI26

The benchmark first issued a warning about “powersave” governor, but I still went ahead, and once completed I change it to “performance” governor:

sudo apt install cpufrequtils
sudo cpufreq-set -r -g performance

1 2	sudo apt install cpufrequtils sudo cpufreq-set -r -g performance

…and ran the tests again. All results are available on OpenBenchmarking. Let’s address the governor results first. cpufreq-info reports that powersave governor […]

MeLE PCG35 Apo Apollo Lake Mini PC Review – Part 3: Ubuntu 17.10

I completed the review of MeLE PCG35 Apo with Windows 10 Home a few days ago, and as promised, I’ve now installed the freshly released Ubuntu 17.10 in the Intel Celeron J3455 “Apollo Lake” mini PC. I’ll start by shortly explaining the step to install Ubuntu 17.10 in the M.2 slot, although you could also install it to the internal eMMC flash replacing Windows 10, then show what works and what does, and finally include a video reproducing the tests I usually do in Windows 10. How to Install Linux in MeLE PCG35 Apo This partially follows the procedure I used to run (not install) Ubuntu 16.04 on MeLE PCG03 Apo mini PC. First you’ll need to download the ISO of your choice (ubuntu-17.10-desktop-am64.iso in my case), and prepare a bootable USB flash drive with the software of your choice be it Rufus, Startup Disk Creator or others. I did […]

Amlogic T962E SoC Powers $55 Alfawise H96 Mini TV Box with HDMI Input, HDMI Output

HDMI input can be a useful addition to Android TV boxes, or media centers, as they allow for functions such as PiP (Picture in Picture), PVR/DVR (Personal / Digital Video Recording), and potentially video broadcasting with the box taking input from your set-top box (or other HDMI device), and broadcasting the video over your network in order to make it accessible to other computer or mobile devices on your home network, or the Internet. We started to see HDMI input on devices powered by Mstar MSO9810 processor a few years, and more recently Realtek RTD1295 processor has become more popular with products such as Zidoo X9S, Beelink SEA I, or EWEAT R9 Plus. Amlogic appears to have joined the fray with Amlogic T962E processor, a family normally used for TVs instead of TV boxes, found in Alfawise H96 mini 4K TV box with HDMI In and Out, 2GB RAM, and […]

Tronxy X3S 3D Printer Review – Part 2: Upgraded Heatbed and RAMPS Board

Karl here. So the bed I mentioned in the first part of Tronxy X3S review is not very good. It took about 10-11 minutes to heat up to 60 deg Celsius. I also mentioned I was going to upgrade the board to a RAMPS board. Today we are going to look at both these upgrades. New Heated Bed I can take no credit for this one but I wanted to pass this along. Folger tech sells a 12v 280w heated bed stick on pad. I picked this up for $20, but is now $22. In order to do this upgrade you will need a MOSFET, 12V/30A power supply, and of course the pad above. Super easy installation. Remove the bed and stick on the self adhesive pad centered. Replace the power supply with new one. Should be self explanatory. In order to power this bed a MOSFET is needed. A […]

Nerdonic Exen Mini is the World’s Smallest 32-bit Arduino Compatible Board (Crowdfunding)

Back in June, we reported about μduino board, which at 12×12 mm may well be the world’s smallest Arduino compatible board. It is based on Microchip Atmel ATMEGA32U4 8-bit AVR microcontroller. But there’s now a new board in town which claims to be the world’s smallest 32-bit Arduino board: Exen Mini measuring 14.9×14.9 mm. While I’m patiently waiting for an Intel’s DMCA request, or more likely an email requesting an update once the name has changed, like I had to do for Atomwear Vigekwear, let’s have a look at what the board has to offer. Exen Mini specifications: MCU – Microchip Atmel SAMD21 Cortex M0+ MCU @ 48 MHz with 256KB flash, 32KB SRAM I/Os via 2x 5-pin 2.54mm pitch headers Up to 8x digital I/O Up to 8x PWM Up to 6x analog (ADC) 1x UART 1x I2C 1x reset Limits – 3.7V, 7mA USB – 1x micro USB […]
