Crazyflie Nano Quadcopter Open Source Development Kit

If you can’t wait until 2014 to get the MeCam, Seeedstudio has something for you: The Crazyflie Nano Quadcopter, which looks similar to the MeCam, but does not feature a camera, its control board is powered by STM32F103CB MCU @ 72 MHz with 128kb flash and 20kb RAM (so, no it won’t run Linux), and at $173 the price is significantly higher. Here are Crazyflie key features: Small and lightweight, around 19g and about 90mm motor to motor Flight time up to 7 minutes with standard 170mAh Li-Po battery Standard micro-USB connector for charging which takes ~20min for the stock 170mAh Li-Po battery On-board low-energy radio@1mW based on the nRF24L01+ chip. Up to 80m range (environment dependent) when using the Crazyradio 2.4 GHz USB dongle Radio bootloader which enabled wireless update of the firmware 32 bit Cortex M3 MCU: STM32F103CB @ 72 MHz (128kb flash, 20kb RAM) 3-axis high-performance MEMs […]

Droid Stick A2 Firmware With Google Play Fix

If you have read my previous review of the Droid Stick A2, I was pretty upset about Google Play since I could not install most of the apps. This is now fixed, and Kimdecent has released a firmware upgrade. Here’s how to upgrade: Download g02refDongle-ota-20130201.rar Extract it in your PC, and copy the files (g02refDongle-ota-20130201.zip and uImage_recovery) to the root of your microSD card (Formatted as FAT32) Insert the microSD into Droid Stick A2 Boot the mini PC normally, and launch the “Upgrade” app Select Local Upgrade, then select g02refDongle-ota-20130201.zip and click on Reboot and Install Package Droid Stick A2 will reboot, and it should start upgrading Android. Done Since I’ve been messing up with Android and broken something, “Reboot and Install Package” does nothing for me (some permissions issues with /cache/recovery/command), so I could not verify this works or not. Finally, I could install it on the first version […]

ARM MCU Development in Linux with Energy Micro’s Simplicity Studio, Eclipse, and CodeSourcery Toolchain

Quite a few months ago, I received an Energy Micro EFM32 Tiny Gecko Starter Kit, but I haven’t done much with it. But recently I saw a tweet from EnergyMicro about Simplicity Studio supports for Ubuntu, and I know it can be problematic to find proper tools for ARM MCU development in Linux, so I decided to give it a try. The first part is about Simplicity Studio, and energyAwareTools which are specific to Energy Micro, but the second part deals with setting up Eclipse and CodeSourcery ARM toolchain for MCU development which should be reusable for other MCUs from vendors such as Texas Instruments, NXP and STMicro. I’ve used a PC running Ubuntu 12.04 64-bit with the instructions below. Installing Simplicity Studio and energyAwareTools in Ubuntu Simplicity Studio is part of the 4 steps of the getting started guide with EFM32 MCUs. It has been available for Linux for […]

Kimdecent Droid Stick A2 Review

At the beginning of December 2012, I wrote a post about Droid Stick A2 mini PC based on AMLogic AML-8726-MX to show some pictures of the device, but I could not really test as the firmware was not complete, and was promise a working firmware soon. Unfortunately, things did not really go according to plans for this hardware, so the firmware never showed up… Luckily, Kimdecent found another version of the device with basically the same specs, a slightly different casing, and more importantly a “working” firmware. The company was kind enough to send me another sample for review. Droid Stick A2 Unboxing Here’s what the new Droid Stick A2 and its accessories look like. Beside Droid Stick A2 mini PC, the package contains a power adapter (5V/2A), a mini USB to USB cable, a short HDMI cable and a user’s manual in English. A close up shows the device […]
