I have been busy for a while with various things. At the same time I was desinging the prototypes for the nanoflyer board to fit in a hubsan quadcopter frame, as well as designing the board for the miniTx transmitter.
I have further shrinked the Brushed Motor Driver board and now it measures 12.5mmX12.0mm and weighs less than 1 gram. It is capable of driving four micro brushed motors rated at 3.7v and can provide up to 2.7A of driving
I wanted to try out a mini cardboard quadcopter frame and here is the result: Figure: Top View The cardboards came from a laptop packaging box. I first drew the arm outlines on the cardboard and then used scissors to
Sneak preview of the new version of the NanoFlyer board I am currently working on. It is smaller, lighter and smarter with more sensors. It has the MPU9150 9 axis sensor and MPL3115A2 precision baro/altimeter on board (missing the picture
I finally got some time to record another video of the NanoFlyer quadcopter flying and also showing the updated MiniTX transmitter. I will make another video of the menu and different settings that can be tweaked from the MiniTX transmitter
This is the mini quad with the NanoFlyer 2.0 board. The board has the newer MPU6050 Gyro/Accel and HMC5883L magnetic sensors. There are total of 5 LEDs on the board to show different indications, on board pcb antenna which has
Here is another tiny project for my need of a small usb to serial device for easy programming and debugging of arduino. The device is built around the FTDI FT230X chip. It needs only a few passive extra components to
Just received the NanoFlyer v2.0 boards from Oshpark and put it together with my hot air station and hand soldering. I have got best results on soldering QFN chips by first tinning the pcb pads with solder and flux, as
