Learn Linux and Raspberry Pi the smart way with this training course under the H4H Maker Academy.
Raspberry Pi is a credit-card sized computer ideal for learning about computing, Linux, interfacing with hardware such as sensors and actuators, as well as programming. It’s cheap, but powerful, and makes it possible to interact with the physical world.
In this course we’ll use the Raspberry Pi to learn Linux as well as some simple programming with Python and some interesting hardware projects.
We’ll conclude the course with setting up a Raspberry Pi as a working FM Transmitter, broadcasting over FM!
30 July 2016 marks the 1st FPV (First Person View) Fixed wing RC (Radio Controlled) Rally in the world!
Henrico Hanekom, an entrepreneur and technology enthusiast, gathered his RC model flying friends who fly FPV recreationally on weekends to take up the unique challenge.
Pilot and Navigator teams braved the winter morning at a field outside the city (Pretoria-East, South-Africa) with great enthusiasm even though they were not quite sure what to expect. Each team had a pencil, calculator, protractor, video headset and radio controlled aircraft handy.

It was only until recently that various technologies like high-power low-weight Li-Po batteries, efficient Brushless motors, long range Video and control systems, open-source Autopilot software and hardware, MEMS (micro-electro-mechanical-systemslike the sensors in your smart phone) and others collided to fuse the exhilarating hobby called FPV flying.
Most people call multi-rotor aircraft “drones”…but few understand that fixed wing aircraft fitted with an auto-pilot system may also be classified as “drones”. There are many races being held for multi-rotors (especially mini quads) where speed and skills are tested, but never before has there been a Rally for FPV fixed wing pilots. Most operators build and customise their own aircraft from components available at hobby shops…typically with wing spans between 1 and 2 meters.

Why a Rally?
The objective of such a Rally is to increase piloting skills, navigation skills and observational skills. It improves the operator’s ability to fly safer and more controlled whilst being aware of their geographical area, weather conditions and understanding the limitations of their aircraft. The Rally is conducted in non-auto pilot flight modes so even though autopilot features are present in the aircraft, it only kicks in when needed as a safety feature.

Each team receives a clue sheet and a map with minimal data. From clues like leg distances, landmarks and direction the navigator has to plot the route and ETA’s (Estimated Time of Arrival) on their map within a certain time frame before they take off to execute the flight plan.
Penalties are incurred when a team misses a check point, make time errors, calculation errors, navigational errors, map observation errors and based on how far they land their aircraft from a line called a spot landing marker.
Contestants walked away with valuable flight experience and important lessons learned.

Henrico Hanekom believes that FPV Rallies can advance the safety and skills of those who fly “drones” recreationally and even commercially in a fun and non-hazardous environment.He hopes to see it become an internationally recognised flying discipline.
This class will introduce students to the Arduino Single Board Microcontroller – a powerful platform for creating devices that interfaces with the physical world. The Arduino can be used in robotics, art installations, 3D printers, and other do-it-yourself electronics projects.
During this class students will:
Build circuits that utilize sensors and output devices that allow the microcontroller to react to its environment.
Learn electronics, programming, and physical computing concepts by building basic projects.
