Whereas we’ve come a good distance when it comes to opening up the world of radio management to open supply software program, a great deal of the itself remains to be closed up. You’ll be able to flash an inexpensive RC transmitter with a neighborhood developed firmware, the truth is there’s an honest likelihood that’s what it ships with, however the itself remains to be an immutable black field. That could be advantageous in the event you’re simply flying an RC aircraft or quadcopter, however what in the event you’ve received one thing a bit extra superior in thoughts?
To deal with this problem, [Alireza Safdari] has spent the final a number of years engaged on a really open supply RC transmitter that may be modified and augmented to satisfy the consumer’s wants, known as the Alpha V1. With the and software program nearing completion, he’s trying to get some neighborhood suggestions on the system earlier than the deliberate crowdfunding marketing campaign kicks off.
From his private expertise, [Alireza] discovered that conventional RC transmitters have their limits once you begin utilizing them for robotics. You’ll typically need enter schemes or units which might by no means happen to the distant’s designers, and also you’ll virtually actually need to have extra channels and capabilities than the unique will enable. One of many massive benefits with the Alpha V1 is that the back and front of the controller are easy acrylic panels, which means you may simply reduce openings or drill holes in them so as to add extra with out having to cope with the (comparatively) ergonomic shapes of a standard transmitter.
After all, that’s just one half of the equation. Whenever you add new , you’ll must make the software program conscious of it. To that finish, [Alireza] says he and his crew have developed a library of adaptable firmware modules which ought to make it very simple so as to add in new elements with out having to get slowed down with software program configuration. In reality, he says the purpose is to permit the consumer so as to add new to the Alpha V1 with out requiring them to write down a single line of code.
The Alpha V1 communicates at 2.four GHz utilizing both XBee or Murata DNT24 radios, and helps as many as 72 particular person channels in addition to two-way telemetry. In case your necessities aren’t fairly so excessive, we not too long ago coated a significantly much less intimidating try at constructing an open supply RC transmitter that may fit your wants.
