DroneShield – Raspberry Pi Powered Drone Detector

In case you are wary of having drones, such as RC helicopters, quadrotors…, flying around your house and invading your privacy, DroneShield can help you detect consumers’ drones by using a Raspberry Pi, a microphone and FFTW library, a C library for computing the discrete Fourier transform. The device will capture the audio with the microphone, analyze the noise spectrum of the drone flying around, and search for an entry in a signature database, and if a match is found the device will then send an email or SMS to inform you of the “invader”. There are complex challenges to overcome, or limitations, with this method, as any background noise will affect the detection, and drone emitting little noise or flying at high altitude won’t be detected. Spectrum analyses should however help avoid false positives such as a loanmowers and leafblowers as those emit a different kind of noise.They also […]

Picuntu Home://io Edition Brings GPU Acceleration to RK3066 based Mini PCs

Earlier this year, Picuntu (RC2), an Ubuntu-based distribution, was released for RK3066 powered HDMI dongles such as MK808, UG802, etc… More work has been going on since them, and Justin Gross (JustinTime4Tea) announced the release of Picuntu Home://io edition on SlateDroid. This distribution is based on Pictuntu RC3, supports GPU hardware acceleration, and lots of packages including Quake 3. GPU acceleration has been available since February thanks to olegk0, but I think it may be the first time it’s packaged into an installation image. Justin added a lot of goodies in this image including: Gaming – PCSX_rearmed Playstation Emulator and ioquake3 (with free demo files, replace with your own original Quake3 CD files) both supporting PS3 controller. Other games include GLTron, Solitaire, B.A.L.L.Z and a few more. Web Browsers – Midori, Firefox, and Chromium with support for Flash Graphics Tools – GIMP, Scribus, Inkscape, ImageMagick, etc… Email & Messaging Clients […]

Quick Review of YS-189 HDMI Switcher

Since I have quite a few devices with HDMI, and I got tired of getting behind the TV to plug or unplug the device, and sometimes I may want to cycle through them for testing, I bought an HDMI switch from Dealextreme for about $11. The device, called YS-189, features 1 HDMI output and 3 HDMI inputs so that you can connect 3 devices to one HDMI port of your TV. There’s also a 5V power jack, which is normally not needed, or so they say, and a small remote control (battery included!) with three buttons to switch between the inputs. First I’ll show a few pictures of the device, and talk about my experience connecting 3 Android mini PCs. Here’s the package with the black box and the remote. At the back there are more details about the device including specification and “user’s manual”. Now a picture of the […]

Arndale Octa Exynos 5410 Development Board is Now Available for Pre-order

After the Arndale board based on Samsung Exynos 5250 processor (dual core Cortex A15), Insignal is in the process of completing the development of Arndale Octa board powered by Exynos 5410 with 4 Cortex A15 and 4 Cortex A7 (aka Samsung Exynos 5 Octa), and howchip.com is now accepting “pre-orders”, at an undisclosed price, and the board is expected to ship by July. A picture of the board is not available yet, but the specifications are (sort of): ARM Cortex-A15 (eagle or big core) Quad CPU with NEON/VFP as high performance processor with 32/32KB I/D Cache, 2 MB L2 Cache. ARM Cortex-A7 (kingfisher or little core) Quad CPU as power-efficient performance processor with 32/32 KB I/D Cache, 512 KB L2 Cache. This processor is architecturally aligned with Cortex-A15 128-bit multi-layer Network-on-Chip (NoC) architecture Cache Coherent Interface (CCI) among Cortex-A15 and Cortex-A7, G2D, and SSS DRAM access through two channels of […]

TP-Link TPmini “Android-on-TV” Box Features 2MP Webcam

Since the beginning of the year, we’ve started to see more and more Android media player with a camera that can be apposed on top of your TV such as the Archos TV Connect. Let’s call them “Android-on-TV” boxes / media players. Several Chinese manufacturers are also selling this type of device, but none of them have brand recognition in the West. TP-Link, however, is relatively well known for its cheap routers, and the company has introduced the TPmini powered by a dual core processor with 1GB RAM, 4GB flash, and a 2.0MP camera. Here are the specs of the device: SoC – Dual core ARM Cortex-A9 processor @ 1.6 GHz + Quad core ARM Mali 400 GPU (They did not say, but it looks like Rockchip RK3066 to me) System Memory – 1GB RAM Storage – 4GB NAND Flash + microSD slot (Up to 32GB) Video Output – HDMI […]

Linux 3.9 Release

Linus Torvalds has announced the release of Linux Kernel 3.9: So the last week was much quieter than the preceding ones, which makes me suspect that one reason -rc7 was bigger than I liked was that people were gaming the system and had timed some of their pull requests for just before the release, explaining why -rc7 was big enough that I didn’t  actually want to do a final release last week. Please don’t do that. Anyway. Whatever the reason, this week has been very quiet, which makes me much more comfortable doing the final 3.9 release, so I guess the last -rc8 ended up working. Because not only aren’t there very many commits here, even the ones that made it really are tiny and not pretty obscure and not very interesting. Also, this obviously means that the merge window is open. I won’t be merging anything today, but if […]

CoAction Hero – Low Cost ARM Cortex-M3 Board Running Open Source CoActionOS RTOS

CoAction Hero is a tiny board based on an ARM Cortex-M3 micro-controller (NXP LPC1759), that makes use of  CoActionOS ecosystem that includes the hardware, but also an open source RTOS allowing multiple app to run concurrently, and a graphical interface to communicate with the board. First, let’s have a look at the hardware specs: Micro-controller – NXP LPC1759 ARM Cortex-M3 processor @ 120MHz with 64kB RAM and 512kB  Flash ROM. Storage – 1MB serial flash chip (pre-loaded with CoActionOS) Expansion port micro USB connector. 40 I/O pins are available on both sides of the board, and the board can be inserted in a breadboard. You can currently connect 2 modules to the board: Bluetooth and LCD device boards. CoActionOS RTOS will come pre-loaded on the board, and if you don’t want to, you don’t even need to know it’s there, and it’s use will be transparent. But let’s have a […]

AMLogic To Unveil 4 Core Cortex A9 AML8726-M8 SoC with 8 Core Mali GPU

Last Thursday, Geniatech announced an upcoming Android Set-Top Box called ATV1800 featuring a quad core AMLogic processor, more memory, and running Android 4.2, and that will support XBMC. They also expect the device to be available in May for 20 to 24 USD more than the dual core version. There are not enough details about the device itself, so I won’t cover it now, but I had never heard about quad core processor from AMLogic. I’ve finally been told it was AML8726-M8 without much details, except it should be available in Q3 2013, which does not seem match May target for Geniatech’s STB. Luckily, a Google search helped a lot, so we already know some of the key features for this new SoC: Quad Core Cortex A9 @ 2.0 GHz (20,000 DMIPS) Eight Core “Next-Gen” Mali GPU with 3,000 MPixel/s fill rate, 110MT/s, and 45GFLOPS. The GPU is said to […]
