DIY Drones now at 90,000 members!

It's customary and traditional that we celebrate the addition of every 1,000 new members here and share the traffic stats. We've now passed 90,000 members!

A few observations on this milestone:

  • It took 12 years to get to 90k members. It's a marathon, not a sprint
  • Although this is a zero-person operation (it runs itself,…

The problem with airspeed sensors

Airspeed sensors have been a major concern for both manned, and unmanned aviation alike. Yet almost every fixed wing or VTOL vehicle is dependent on it. So what is wrong with these sensors and why are they used?

How an airspeed sensor should work

A standard airspeed sensors consists of a pitot tube, a temperature sensor and 2 pressure sensors. The pitot tube has 2 ports (holes), one at the tip (like an injection needle) which is called the dynamic port, and…

Sensors for Attitude Estimation

Hello UAV enthusiasts,

I recently created a slide deck on the topic of sensors for attitude estimation (i.e. gyroscopes, accelerometers and magnetometers). In these slides, I review

  1. Installation considerations,
  2. Stochastic models,
  3. Bias characterization,
  4. Sensor calibration, and
  5. Conceptual models.

The methods and concepts contained in these slides have been "battle tested''. That is, these are the methods and concepts I used…

Developing Long-Range (600km) electric UAV

This is our new concept for a long-range fixed-wing UAV. 

The benefits of having a long-range UAV in search and rescue operations as well as in urgent transportation of blood and medicines are astonishing in terms of costs and effectiveness.

Surveillance operations and mapping are also two sectors where a similar air vehicle is essential…
