DIY Servo Signal (PWM) to PPM Converter - RC Groups - Nightly

It was originally developed for a wireless buddy box but also for FMA and Paparazzi autopilots so they don't have to use special receivers or hack into a regular one to get PPM. It only costs a couple bucks and can be built in minutes. The conversion routine is only 20 something instructions long. The diagram shows Tiny13 pinout for a servo connector and Corona 410 RX.

Attitude Heading Reference System features miniature design., MicroStrain, Inc. - Nightly

Williston, Vermont - April 8, 2009 - MicroStrain Inc has released the latest in its line of attitude heading reference systems (AHRS). The 3DM-GX3-25 AHRS is the first of the 3DM-GX3 family of miniature inertial systems to be released into the market. With versions weighing only 11.5 grams, it is the smallest and lightest AHRS on the market today. Camera Control / Stabilisation with x-IMU - YouTube - Nightly. Camera control and stabilisation via PC. Coding - Nightly. I've now finished coding up SplineNav version 0.2.

Coding - Nightly

It's almost a complete rewrite from version 0.1. Besides flying smoother and using processor resources more efficiently, it now restricts maximum speed to prevent lag. For example, if you're flying fast into a strong headwind, then altitude may get low due to insufficient downward thrust, and position may also start lagging target, resulting in corner cutting. SplineNav now tracks this, and continuously and smoothly adjusts target speed to allow the copter to keep up without major altitude loss. So it's now completely safe to crank up the speed settings and fly SplineNav really fast. SplineNav Waypoints I collected the waypoints for this video while flying FPV, and flipping the channel 8 switch at each point I wanted to record. 2-Axis Gopro 3 Brushless Camera Mount Gimbal w/ Motor & Controller for Gopro3 Aerial Photography - Free Shipping - DealExtreme - Nightly.

Exchanging the SAW filter in a 0.9/1.3GHz receiver for a better one. This modification requires advanced soldering skills as well as a powerful soldering-iron.

Exchanging the SAW filter in a 0.9/1.3GHz receiver for a better one

The RF tuner in the 900MHz and 1.3GHz receivers are originally designed for satellite receivers and have a pretty wide bandwidth compared to what’s needed. So why is having a wide bandwidth bad? All bandwidth not used leads to RF noise that reduces the receiver sensitivity, which means shorter range. Inside of the video receivers there is a SAW bandpass filter. This filter is located in the intermediate frequency (I.F) stage in the RF tuner and it determines the video bandwidth. How To Read RC Receiver PPM Stream - Nightly. Many RC Transmitters and Receivers provide access to the PPM Stream, this is a single stream of pulses which includes the information for all of the receiver channels in a single connection.

How To Read RC Receiver PPM Stream - Nightly

This stream can often be accessed by removing the receiver case and adding a single wire to an existing connection within the receiver. If we can gain access to this stream we can write smaller, faster code and only need a single interrupt pin to read all of the receiver channels. Using a single built in interrupt to read multiple channels is much faster than using pin change interrupts which leads to a visibly smoother output signal for your servos and ESCs.

This post concludes with a library which can be used to read a PPM stream using a single interrupt. The same library is also able to output upto 18 servo signals from a single Arduino UNO with no additional components. Scroll down for a video of the library and an RC Receiver hack in action - What does the PPM Stream Look Like ? Category:Autopilots - Paparazzi - Nightly. One of the great advantages of Paparazzi is support for multiple hardware designs.

Category:Autopilots - Paparazzi - Nightly

The old Paparazzi board where based around ATMega MCUs. The current autopilots are designed around two primary processors: STM32 series microcontrollers LPC21xx series microcontrollers There are active and current autopilots designs using both architectures. Not all autopilots have the same capabilities, peripherals or features, but each has advantages in different applications. 9xVoice Mod - 9X Guides - Nightly. This mod adds voice alerts to the 9x transmitter using a custom circuit board with an Atmel ATMega microcontroller that plays voice files contained on a microSD card.

9xVoice Mod - 9X Guides - Nightly

After the manufacturer of the Emartee Sound Module used in the original voice mod, changed the firmware which made it unusable, a new design was created to remove the reliance on 3rd party hardware. This whole process is documented in the forum: Audio (voice) - Stock 9X PCB This mod is not for the faint of heart, as you'll need to be experienced in fabricating PCBs & flashing new Atmel ATMega microcontrollers. There are several approaches to doing this mod, I will describe the method using MikeB's PCB design. Note that this guide is a work in progress, I'm documenting as I'm doing the mod. IMPORTANT: There are a few mods to the original circuit, I am working on those, please do not use the current schematics & layouts until I update them. Modesw - Уголок самоделкина - Nightly.

Video introduction to Moteino Rev1: Video introduction to Moteino Rev3 and RFM69H/RFM69HW transceivers and library: Moteino is a low cost low-power open-source wireless Arduino UNO development platform clone based on the popular ATMega328 chip used in traditional Arduinos, making it 100% compatible with the Arduino IDE (programming environment).

LowPowerLab - Nightly

Unlike traditional Arduinos, the regular Moteino does not include an onboard USB-Serial converter, instead you need to use an external FTDI adapter to load sketches, the advantages being lower cost, smaller size. They are compatible with any other Arduino clones that use the popular HopeRF RFM12B transceiver or the newer RFM69 transceiver. Moteino also comes with an optional SPI flash chip for data logging or wireless programming. Safety & Perfomance Through Innovation - Nightly. Microstrip Patch Antenna Design - Nightly.

Spherical Parachute Patterns - Nightly. This web page will produce patterns for hemisphere parachutes for model rockets. Instructions for constructing the parachutes can be found in the May/June 2000 newsletter of the Northern Illinois Rocketry Association. The article describes the construction of 12 inch diameter parachute with 8 gores and a 2 inch diameter spill hole. This web page will produce patterns for other sizes of parachutes.

As you are considering the size of your parachute, keep in mind that a spherical parachute has twice the drag coefficient of a comparable sized parasheet style parachute that comes with most model rocket kits. Parachute shroud lines should be 1 1/2 times the diameter of the parachute. Patterns include a 1/4 inch seam allowance. Please check your print settings before printing the pattern.

Skywalker X8 - Video and Telemetry via 3g internet - DIY Drones - Nightly. Here is a short video presentation of my Skywalker X8 UAV using 3g broadband internet for video and telemetry. Onboard my X8 i have this ZTE MF60 3g/Wifi router which handles the communication for the APM2.5 and the Raspberry Pi model B.

I didn't wanna use the Dronecell because i will place the load away from the APM2.5. I could have put a 3g USB adapter in my Raspberry Pi as well, but the Pi have more than enough to do transcoding the video-stream, so i use a Cisco Wifi USB adapter in my Pi to communicate with the 3g router and GCS. The telemetry from my APM2.5 is sent to a Serial 2 Wifi converter which then is connected via Wifi to the 3g router.

I then connect to my APM2.5 using TCP from Mission Planner. The Raspberry Pi are using VLC Player for Linux to transcode the videostream from the Microsoft Lifecam webcamera to a resolution of 352x288 at 500kbit/s and 10 fps. 3D Robotics APM 2.5+ Autonomous Flight (Part 2 – Setup) » Odd Copter - Nightly.
