Moderator Cops with Drones: Alameda Co., CA Weighs Technology vs. Privacy

Here's a relatively good summary of the privacy issues raised in the recent Alameda County (Oakland, CA) public protection committee meeting where the issue of a drone purchase was discussed.

For a long time, drones - unmanned aircraft - were used only by the military. Now local law enforcement wants them for police work such as surveillance…

Joystick2ppm - A cheap joystick-based remote control system

I started this project as an attempt to reduce the amount and cost of hardware required to control a UAV. Since many UAVs already have a radio modem as their telemetry link, I wanted to try piggybacking a control link over the radio modem instead…

We recently got a phantom in to play with and see how it was put together, it's a great little drone for basic flying and features. Being an ArduCopter guy and having used APMs on our SD systems since the biggining I though it would be a fun project to stick an ArduCopter board in the Phantom. It was pretty easy to do! Will…

How to trigger a Canon camera through an RC transmitter


In this video, I go over how to trigger a Canon s95 camera through an rc transmitter, without taping a servo on top to push the shutter button. Canon cameras use a firmware hack called CHDK that allows shutter control through the usb port. With a simple switch from Turnigy, we can trigger the camera from the transmitter.

Turnigy switch:…

Retrotechtacular: The Fourier Series

Here’s a really quick video which takes a different approach to understanding the Fourier Series than we’re used to. If you’re a regular reader we’re sure you’ve heard of the Fourier Series (often discussed as FFT or Fast Fourier…

Researchers increase lifespan of lithium-sulfur batteries


Technology has advanced markedly since the dawn of the silicon age, but our portable gadgets and gizmos are still largely held back by the limitations of their power source. Scientists at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden…

NugePilot: Communication Timing Issue


For the past year I have been engineering my own autopilot shield for the Arduino Mega(and unintentionally the Due). I hope to be finished by the time AVC rolls around, but I have run into an issue. I currently an using 3 separate Arduinos(Mega: autopilot, ArduIMU, and Atmega328: fail…

Ardustation 2 Aircraft Battery Low Voltage Warning (2.0.18)

I've been working on the Ardustation 2 software since August 2011 and I've finally gotten around to adding a feature that has been asked for more than once: a buzzer warning when the received Mavlink aircraft battery voltage has dropped at or below a set value.  The buzzer is sounded  ( at LCD…

Ionic Thrusters for Drone Propulsion?

Ionic thrusters use high voltage to ionize air and create an airflow, which in the right configuation can create thrust with no moving parts. I've tried an experiment like the above, and barely generated enough lift to raise a little balsa and aluminum foil off a table, but MIT says they can do far…

Drone industry boosters pilot controversial local growth plan

David Wagner, Fronteras Desk

When it comes to the controversial unmanned aircraft known as drones, business is booming. That could mean scores of new jobs for San Diego, but privacy defenders say courting the drone industry could cost us our civil liberties.

An alliance made up of Utah universities and the Governor’s Office of Economic Development is making a bid to turn part of the state into a testing ground for “unmanned aerial systems.” You may know them as drones.

But officials from…

DIY vario and head tracker


I build a couple of DIY electronic devices from open source projects.


I thought those could be useful to someone here on DIYDrones and they deserve a little visibility here too.

They are based on Arduino Nano and very cheap to build.

In this video I'm using both for the first time, with…
