Gesto is a Wearable Gesture Motion Solution for Makers (Crowdfunding)

A while ago I wrote about an open source prosthetic arm controlled by signals generated by your arm’s muscles. It used an Arduino board, a bio-feedback shield by Olimex, and inMoov Hand for the arm and hand. It worked, but lacked accuracy. Gesto is a solution based on boards powered by Atmel MCUs that looks somewhat similar, but with higher accuracy (over 100 gestures have been tested), and the project has now been launched on Crowdsupply. Two kits are available: Gesto Stella EMG circuit – ADS1294 MCU – Atmel ATmega1284p 2x EMG cables connector Through holes with GND, PWR, MOSI, MISO, CLK and SC Dimensions – 35 x 20 mm Includes 16 disposable electrodes and relevant cables Gesto Caelum EMG circuit – ADS1294 MCU – Atmel ATmega1284p Sensors – 3-axis accelerometer (MMA8652FC) Connectivity – Bluetooth (RN42-HID) 2x EMG cables connector USB – Micro USB connector Programming – ICSP connector Power […]

Arch Linux ARM Can Now Be Installed on Rockchip Based Hisense Chromebook

Hisense Chromebook C11 is one of the $149 Chromebooks powered by Rockchip RK3288 processor recently launched. So far, I could not find instructions to install any Linux desktop distributions on this type of platform, but now Hisense Chromebook (codename: veyron_jerry) appears to be the first Rockchip platform officially supported by Arch Linux ARM (ALARM). Hardware video decoding won’t work, 3D graphics acceleration is most probably not working either, and it’s not clear if all hardware parts are supported, and the built-in wireless module is said to break under high throughput, so a USB WiFi dongle or Ethernet adapter is recommended instead. But at least if you follow the installation instructions, you won’t modify your Chrome OS installation on the eMMC flash, as Arch Linux ARM will boot from external storage, either from an SD card or a USB flash drive, so it should be completely safe to try it out.

Zidoo X9 Android HDMI Recorder & Media Player Gets Picture-in-Picture (PiP) Support

Zidoo has released another firmware for their X9 Android mini PC with HDMI input, which implements Picture-in-Picture (PiP) support, on top of the existing HDMI video recording. That’s the first Android TV box that I know of that supports it, although I’ve seen Geniatech demo HDMI input and PiP with their ATV1810 last year, but it does not seem to be available for sale anywhere. Changelog for Zidoo X9 firmware version 1.0.3.5: Added PiP function, You can press the TV button on the IR remote to enable it. Optimized audio compatibility. Fixed various Player bugs – Audio compatibility, OSD timeout, typos fix, etc… Fixed various File Manager bugs I don’t have the box with me right, so I could not try it, and Zidoo did not reply to my request for pictures and demo in time for this post, so I’m not sure if there are any shortcomings with the […]

Grain Media 8136S / 8138S are Low Cost HD IP Camera SoCs

A few times, my readers told me they really like comments on this blog, and they liked to check recent comments on the left sidebar, and some even subscribed to the Comments RSS Feed, although it might quite busy at times, especially during giveaways. Recently, an interesting conversation started in the comments section about low cost IP camera chips by Grain Media 8136S and 8138S SoCs respectively supporting 720p and 1080p video recording, and cheap enough to make a sub-$10 IP camera board (BoM cost). Beside the maximum resolution supported, GM8136S and GM8138S are mostly similar except the later also supports Gigabit Ethernet against Fast Ethernet for the lower end version, different clock speeds, and some other (minor?) differences. There’s also GM8135S with 512 Mbit RAM (SiP) against 1Gbit RAM (SiP) for GM8136S, and GM8138 including a DDR controller for external memory, while GM8138S including 1Gbit RAM (SiP). Grain Media […]

Android 5.1 SDK Release for Rockchip RK3128 Based FirePrime Board

T-Firefly has just announced the release of Android 5.1 SDK for their newly announced Fireprime development board powered by Rockchip RK3128 quad core Cortex A7 processor. You can get the SDK (fireprime_android5.1_git_20150612.tar), a 6.1GB download with full source code for the board via Baidu or Google Drive, and then upgrade it to the latest version with git pull on the company’s bitbucket account as explained in the Wiki. The SDK must be specific to Fireprime board, but it should be feasible to use to create / modify Android 5.1 firmware for other RK3128 products. If you don’t need the source code, but would just like to install the firmware for Android 5.1, and the other image recently released (Ubuntu 15.04 Desktop or Server, or Android 5.1/Ubuntu 15.04 dual boot image) via the links provided in the announcement. Thanks to Nanik for the tip.
