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 […]

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. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in […]

Tronsmart Draco H3 TV Stick Firmware and SDK Released

Tronsmart Draco H3 is a low cost HDMI TV stick powered by Allwinner H3 quad core processor. At $35, the device costs about $5 more than Amlogic S805 based sticks like MK808B Plus with about the same specs (quad core Cortex A7/A5, 1GB RAM, 8GB flash, HDMI out..), but with the added benefit of 4K @ 30Hz support. Tronsmart has now released some firmware files as well as Linux kernel and an Android SDK. Two firmware files have been released: Tronsmart_Draco_H3_720p_Kernel_20150526.zip – Firmware with 1280×720 framebuffer for better performance Tronsmart_Draco_H3_1080p_Kernel_20150526.zip – Firmware with 1920×1080 framebuffer for higher resolution Please note that the resolution will only affect the user interface, and when you play videos you should get the resolution selected in Android settings. So if you play a 4K videos it will truly show as a 4K video on your TV, even though the user interface is only 720p, at […]

ESP8266 SDK 1.1.0 is Now Released Under an MIT License

ESP8266 is the now famous dirt-cheap Wi-Fi SoC used for IoT applications. It can be used by hobbyists and companies alike. But for the later, there was a licensing issue as Espressif ESP8266 SDK was initially released under the GPLv3 license. GPL code is great and lots of open source projects are released under the most common open source license. But since proprietary, closed source software has still its place in the market place, some other more permissive licenses such as LGPL are used for library, and Android for example has an Apache License 2.0. So previously, if you developed an application using ESP8266 SDK, you’re code would have to be GPL too, since the license is viral. It would also cause issues if you had released your application under an Apache or MIT license. But now, all is well, as Espressif released ESP8266 SDK 1.10 under an MIT license, […]

Allwinner H3 Based Orange Pi 2 Board Price Drops to as Low As $25

As Raspberry Pi Model B+ price got reduced to $25, some competitors also decided to bring their price down. Shenzhen Xunlong Software, the maker of Orange Pi board, decided to decrease their Orange Pi 2 and Orange Pi 2 Mini boards by $5 to respectively $30 and $25 plus around $2 shipping. Both boards are based on the same PCB, but the mini version lacks WiFi. Let’s refresh our memory with the specs: SoC – Allwinner H3 quad core Cortex A7 @ 1.6 GHz with 256KB L1 cache, 1MB L2 cache, and an ARM Mali-400MP2 GPU up to 600 MHz System Memory – 1GB DDR3 Storage – micro SD card slot (up to 64GB) Video Output – HDMI (CEC and HDCP support), AV port Audio I/O – HDMI, AV port, on-board microphone Connectivity – 10/100M Ethernet, 802.11 b/g/n Wi-Fi (Realtek module, not found on mini version) USB – 4x USB […]

FireWRT is an OpenWRT 802.11ac Board Powered by Mediatek MT7621A Processor

There are plenty of low cost 802.11n routers or boards supporting OpenWRT, even starting at $10 or less such as A5-V11 mini router, but if you’re looking for something a bit more powerful with 802.11ac connectivity, options are much more limited, especially if you need something at a lower cost. One option is Xiaomi MiWiFi router based on Mediatek MT7620A with 64MB RAM, and T-Firefly team is now working on FireWRT board based on the more powerful MT7621A processor coupled with 512 MB RAM, and 16 MB SPI flash. FireWRT specifications: Wi-Fi SoC – Mediatek MT7621A dual core MIPS 1004Kc processor @ 880MHz System Memory – 512 MB DDR3 (Beta version: 256 MB) Storage – 16 MB SPI flash memory, 2x SATA 3.0 ports, micro SD card slot Wi-Fi 802.11 b/g/n @ 2.4GHz up to 300Mbps 802.11 a/n/ac @ 5 GHz, up to 867Mbps (AC1200 class router) External High-Gain Antennas […]

Orange Pi Plus (Allwinner H3) Firmware Images and Linux SDK Released

Orange Pi Plus is a development board based on the new Allwinner H3 quad core Cortex A7 processor that supports 4K video output and decoding. The boards comes with 1GB RAM, 8GB eMMC, HDMI output, Gigabit Ethernet, Wi-Fi, SATA and more, and sells for $49 on Aliexpress. When I first covered the board in February, it was already listed on Aliexpress, but I could not find any firmware image, or source code, but this has now changed. There are now four firmware files: Lubuntu_1404_For_OrangePiplus_v0_8_0_.img.xz – Lubuntu 14.04 image Raspbian_For_OrangePiplus_v0_8_0.img.xz – Raspbian for Allwinner H3 orangepi-plus-debian-server-card-v0.9.img.xz – A Debian server image sun8iw7p1_android_orangepi-plus_uart0.rar – Android 4.4.2 image that needs to be flash with PhoenixCard in Windows (Linux tools are not working yet) Beside the firmware images, the company also releases a Linux SDK (h3-lichee-1.0.tar.gz) with Linux 3.4 kernel source code, u-boot, and relevant tools. I assume these should also work on Orange […]
