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 […]

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.
