This robot is balancing a standard pencil based only on visual input from two “dynamic vision sensors”. These sensors do not rely on a constant background, as shown when rotating the platform during operation. To achieve the balance it uses two servo motors and two Dynamic Vision Sensors one for each axis. These sensors “watch” for changes in pixel contrast, outputting a positive or negative number based on the direction the pencil is beginning to fall. An NXP2103 running at 64 MHz reads in the values and drives the pair of servo motors accordingly. [via]

The LiPo balancer cell acts like a big and very accurate zener diode; when the cell voltage is under a threshold fixed by the user the system is in “idle state” and watch only for the voltage with a equivalent resistance of some KOhm and a negligible current shunt. When the voltage reaches the threshold the balancer element will start to shunt current from the cell with an internal power resistor. [via]

This is a Li-Po charger and balancer project for R/C hobby.The charger circuit is based on the circuit of Electron head and all folks in the DIY electronics topic on the rcgroups.com. [via]
