GTEK GP100 Rugged Waterproof Bluetooth Speakers Can Be Used in the Bathroom and Outdoors

I normally put my smartphone on a shelf to listen to music while taking a bath or showering, and a few years back I thought about using Bluetooth speakers, but few solutions were waterproof, and/or the price must have been high, so I forgot about it. Following a post on ARMDevices.net about GTEK speakers, I found out there are now many waterproof Bluetooth speakers to choose from with prices starting as low as $7. But I found GTEK GP100 speakers quite interesting, as beside being waterproof (IPx7), there are also rugged and suitable for outdoor activities, come with a 3,000 mAh battery good for 8 to 10 hours, and can fit into your bicycle bottle’s holder. Some of key features of GTEK GP100 (GT-D201): Connectivity – Bluetooth 3.0 (Website also says Bluetooth 2.1 + EDR); 10 meter range Speakers – 2x 5W (or 3W?); 80db+ SNR; 80Hz – 18Khz frequency […]

ChromeCast 2.0 and ChromeCast Audio Announced for $35

Google released the original ChromeCast in 2013. The $35 device allows users to stream online video from your smartphone to your big TV, and since then Google and the community has brought various improvement to make more with the device, and thousands of apps can be installed in the little device. Google has now released a new ChromeCast, as well as ChromeCast Audio to stream audio to speakers. The hardware has been upgraded but the complete specifications are not available, but we do know ChromeCast 2.0 support 802.11 b/g/n and 802.11ac for higher quality 1080p video streaming, and Marvell tweeted about the new ChromeCast devices, so it’s likely another Marvell SoC has been used, maybe Armada 1500 Plus (88DE3108) [Update: ChromeCast 2.0 is based on Armada 1500 Mini Plus (88DE3006) dual core Cortex A7 processor] The new ChromeCast still works with iPhones, iPads, Android phones and tablets, Mac and Windows […]

Mini Review of Semlamp SL-011 Audio Controlled Relay for Home Lighting

Last month, I wrote about Semlamp SL-012 a smartphone controlled light switch for 2 lamps that sells for about $11 on DX, and contrary to most others don’t use Bluetooth, nor Wifi, but instead a simple microphone.

The top of the board features JQC-3FF 24V relay supporting up to 10A @ 277VAC, as well as […]

MINIX NEO Z64W (Intel Atom Z3735F) mini PC gets HDMI Audio in Ubuntu

We’ve been able to run Ubuntu on Intel Atom Z3735F mini PCs, as well as other Linux distributions, for a while, but with an important caveat: HDMI audio would not work, so instead you had to use an external USB sound card to get any audio. Luckily the problem seems solved, as Linuxium has now released a script (audio-wifi-minix-neo-z64-release.sh) and relevant files that will patch your system to enable HDMI audio, and WiFI on MINIX NEO Z64W running Ubuntu. Ian Morrison (Liuxium) compiled a Linux kernel and the Wi-Fi driver, together with a modified DSDT (Differentiated System Description Table) table to fix an ACPI bug. He used John Pemberton’s Bay Trail Audio HDMI patch, as well as help from Paul Kendall for identifying the ACPI DSDT table bug, Bastien Nocera (hadess) for the wifi source code and DroidMote Server / Client for the wifi pointer. A quick demo shows WiFi […]
