What’s more disruptive to the drone first-person view (FPV) experience than dropouts in your video feed when you’re in the middle of a race? Probably nothing, and there’s probably also not much you can do about it. Or is there? Might a simple tracker based on RSSI help keep your video signal locked in?
Honestly, we’re not sure it would, but we think it’s pretty nifty to see [FlyerFpv]’s tracker following his drone around. The idea is simple and uses the full-diversity FPV receiver he already has. Diversity receivers constantly monitor signal strength from multiple antennas to determine which one to listen to, which improves reception quality. [FlyerFpv] sends the RSSI outputs to analog inputs on an Arduino which drives a servo to keep the signals as close to each other as possible. The Arduino and the DC-DC converter needed to power it fit nicely inside the receiver case with no modifications, which is a nice touch. With a 3D-printed servo mount and some fancy directional antennas, the setup keeps pretty good track of his drone now. See it in action below.
Sure, the response could be snappier, and we’d love to see another receiver and servo added to track pitch as well as yaw. For a first pass, we think it’s great, but [FlyerFpv] should enjoy it while he can in case AI takes over our flying fun soon.
The Open Source Hardware Association is now accepting applications for the Ada Lovelace fellowship which provides free admission to the Open Hardware Summit and a $500 travel stipend. One of OSHWA’s goals is to foster a more diverse community within open source. As part of this, Ada Lovelace Fellowships are open to women, LGBTA+, and people of color. There are a total of 10 fellowships available and applications are due by April 30th. The Open Hardware Summit will be held on September 27th at MIT.
The fellowship program, founded by Addie Wagenknecht and Alicia Gibb in 2013, builds on the ideal that Open Hardware is one way to reduce the barriers associated in access to technology. Removing some of the financial barriers associated with attending the Summit will help to ensure more people of diverse backgrounds are involved in shaping the Open Hardware world. In addition to the talks shared at the gathering, over the last several year OSWHA has been evolving the Open Hardware definition and an Open Hardware certification.

There were a lot of very technical talks at Hackaday Belgrade. That’s no surprise, this is Hackaday after all. But every once in a while it’s good to lift our heads up from the bench, blow away some of the solder smoke, and remind ourselves of the reason that we’re working on the next cool project. Try to take in the big picture. Why are you hacking?
[Phoenix Perry] raised a lot of big-think points in her talk, and she’s definitely hacking in order to bring more women into the field and make the creation of technology more accessible to everyone. Lofty goals, and not a project that’s going to be finished up this weekend. But if you’re going to make a positive difference in the world through what you love to do, it’s good to dream big and keep the large goal on your mind.
[Phoenix] is an engineer by training, game-coder by avocation, and a teacher for all the right reasons. She’s led a number of great workshops around the intersection of art and technology: from physical controllers for self-coded games to interactive music synthesis devices disguised as room-sized geodesic domes. And she is the founder of the Code Liberation Foundation, a foundation aimed at teaching women technology through game coding. On one hand, she’s a hacker, but on the other she’s got her eyes on a larger social goal.
