How to choose battery for Racing Drone

How to choose battery for Racing Drone Larger battery provides longer flight time. on the other hand It increases weight and thous decrease speed As the battery gets heavier, the increase in flight time becomes smaller. Eventually it will reaches a point where it just doesn’t gain any more flight time with bigger battery (even lose flight time). LiPo batteries (short for Lithium Polymer) are a type of rechargeable battery that is the battery of choice in the RC world . Chacteristic of Lipo Betteries RC LiPo batteries are light and can be made in any shape.

Botboarduino drivers

Ok guys it's been a while since I've been on I'm glad everything is picking back up.

I recently had to wipe my computer after getting a virus. Which means I lost all my drivers and code and etc. I managed to get arduino up and running but my botboarduino needs drivers to work. I'm kinda freaked out about catching another virus and I can't seem to find the correct drivers for ft232 uart. I tried one place but it keeps asking me for a password to open it. And when I point the device manager it refuses to see the zip file.

My artificial neuron approach

February 12, 2015

A single artificial neuron can represent some simple Boolean functions like OR, AND or NAND and some like XOR not, because a single artificial neuron can only learn linearly separable mappings.

Example. Perceptron for the AND function:
