Vicacopter – Open Flight Robotics

Source code and many notes used in Vicacopter, the 1st English language source code for a fully functional helicopter autopilot.

Vicacopter - Open Flight Robotics

Vicacopter uses a ground computer for flight control. An 8 bit airborne microcontroller handles rate damping, PWM, & sensor capturing. The ground computer handles navigation & provides a simple instrument panel. This was the cheapest & most flexible way to fly. The system can be converted to a completely airborne autopilot very simply.

Vicacopter - Open Flight Robotics

Some Features
  • Automated landing & takeoff
  • Sonar position sensing for indoor flight
  • GPS position sensing for outdoor flight
  • Ground station instrument panel
  • Untethered communication from pilot to ground station
  • Curved or linear paths

The Tri-Roter one used 3 gyros for short term rotation sensing, 2 accelerometers for long term tilt sensing, 3 magnetometers for long term heading sensing, a high quality GPS module for horizontal position, a barometer for altitude sensing. A 3rd accelerometer was too sensitive to vibration & altitude changes to be any good. Because of the long term sensors & the very stable gyros, the orientation was always pretty accurate & didn't drift.

Fly Electric-- Radio Controlled Model Aircraft

This site is for flyers of Radio Controlled model aircraft wanting to find out about successful Electric powered RC modelling.

Fly Electric-- Radio Controlled Model Aircraft

"On this site I showcase big electric planes, have loads of free plans for smaller ones, cover many interesting contruction topics and provide circuit diagrams and advice for lithium batteries."  - David Theunissen

PIC and AVR Projects  - Designing PIC microcontroller-based devices to monitor lithium voltages. Individual cell low voltage cutoff, lithium tester and servo controller circuits. Simple data logging. Tutorials to help beginners to get started.

Brushless Free-Flight Timer

Brushless Free-Flight Timer - The page describes how to convert a cheap commercial speed controller into a light, easy to use, brushless free flight timer. It is also a good introduction to brushless ESC's and you could even build your own.

DIY Radio Control Electronic Projects

This project, called "Simple-Timer" is a programmable Timer and electronic switch with an integrated LiPo Battery Monitor that is based around a PIC microcontroller.

Simple-Timer

The "Simple-Timer" includes a fairly accurate timer that is programmable (via pushbutton) by the user and can be programmed to time a 5, 10, 15, 20,25 or 30 minute event. When the timer/switch is enabled (tap small pushbutton), the onboard LED indicates the output is active by lighting solid (the circuit also outputs the same voltage as your supply/battery voltage using a PN2222 NPN transistor or a high current MOSFET).

PIC RISC microcontrollers - Peter Luethi

This website provides you helpful information about Microchip PIC 8 Bit RISC microcontrollers. Several assembler source code listings are available for non-commercial use.

PIC RISC microcontrollers - Peter Luethi

There are also tools for using your PC for measuring or regulating electronic applications. I'am working on several projects, e.g. a precision digital altimeter to use in my radio controlled airplanes.

Precision Digital Altimeter

Precision Digital Altimeter

The current concept incorporates a wireless transmitter and receiver and is thought to be used for remote controlled airplanes or appliances with two seperate parts. In other words, we have one dedicated transmitter (acquisition, filtering) and one dedicated receiver part (user-interface, look-up table, calibration, storage),....
