Another take on the CF frame

In the last post I went through the process of designing and realizing my first Carbon Fiber-based H-quad. While the molding and lamination process itself was successful, the design was based on an open section, a fact that made it twist excessively even though it was quite resistant to bending. I thus went on to

VL53L0X as an Altitude Rangefinder

I recently ordered a VL53L0X sensor carrier from Pololu, with the aim of using it as a lightweight rangefinder for my latest build. VL53L0X is a Time-of-Flight (ToF) sensor; it measures distance by measuring the time it takes for a pulse of light to travel to a target and back. This is some serious stuff for

On the Road to a Full-CF Aircraft

The main driving force behind my current UAV experiments is lowering aircraft weight and noise. In principle though, this should not come at the expense of other factors, such as flying time, rigidity, responsiveness and crash-worthiness. So with these in mind, and after the eventual success of my last build, I’ve been planning for some

Flash & Burn, ESC edition

Many ESCs produce a high-pitched whining noise while running the motors. This is a result of the current switching that happens at the ESC. In many models, the frequency of switching is in the high audible range, and this translates to whining noise. If you’ve been following this blog for some time, you;d know that one of

S01E01: The W-500

It always starts with an F-450, or a clone of it. Always. Unless you’re a pro willing to cough up a five digit figure just to get in the air, or you’re going for the RTF stuff, you must have come across an F-450 in your multicopter ventures. I think that DJI should be proud

Hello world!

Welcome to Unmanned Build, at the time known as UAV Build. When I started building my first drone some time ago, I had in the back of my mind to eventually share my DIY adventures with the community. This blog is the materialization of this idea.  I feel that at this point at last, and after several attempts, successes
