Terrence Howard offers $15000 to make a lynchpin fly with multirotor parts, Joshua Bardwell announces the project, and today Drone Mesh says that this whole affair disrespects the community. If this does not sound like a drama, then I don’t know what does.
Let’s talk about the part of the community that does not feel disrespected, is this worth the money ($15000 is not that much), can this be done in around 1.5 months, and what exactly has to be done.
If you decide to participate in the lynchpin, here are some practical pointers as well: standard PID, gyro, accelerometer, and a dynamic mixer.

Completely off topic: $45 in Rotor Riot store for a few 3D printed parts and sticks for the frame model is quite a lot to be honest. But it’s my personal opinion.

I hate this trend to see everywhere reasons to be offended. Somebody offered a cool challenge, like on a hackaton – the more such challenges, the better. It would be pity if people would stop coming up with ideas and to proposing prizes for solving them in a fear to be called disrespectful.
and its 25,000 not 15,000
If you can’t do it just shut-up, and let other do the challenge, damage their brains and ruin there life ???
Yes it will take a lot of money to get this to work
Your analysis of the way the mixer must operate is one reason I find this project really fascinating. But it does help explain why maybe the $25k prize is not enough for the work involved. To say, “you just rotate the mixer based on the gravity vector” sounds simple but if the gravity vector is always affected by centrifugal force, it seems like the mixer will be really confused when the aircraft is moving and this can result in a feedback loop that makes the aircraft unstable.
Hmm, I like your thoughts on the subject, the angle you took, and the way you went over it. I am thinking of a different way about the “skeleton”. To me, the main issues outside of what you said are also about: how to make it modular; power it; how to link it to others, so they did not get in the way of each other; share power between connected parts, resonating issues within one unit and then many; forced loop feedback; the gyroscopic effects of all the different rotors acting upon one another in any orientation; and many others that just make my head hurt. The code needed to make sure all things “listen” to each other, start and stop properly, and do it smoothly is way beyond my level of abilities. I also do not think it will be small. First prototypes will likely be very clunky due to the power/weight ratio and the expected features. To your point, I do not think it will be quick as I do not think many of the parts are readily available.
I believe the rule of the competition were very loose and nothing needed to be finished within the time limit. More of a long term project.
Is the contest limited to 6 motors or could you use 12.. .. I’ve been looking over the contest but have found it.
A cube would be a better shape, because by recessing the 6 props slightly inside the center of each outside frame square of the cube (like a tesseract ), you’d have the same landing on any side arrangement. But here’s why a cube would be so much better: Standing on a corner, all six sides would be producing thrust. It gets more interesting and far more doable, when instead of one propellor per side, you put a whole 4 propellors or a quadcopter per side. Imagine a 6 sided die with every side being “4” or 4 dots and you get the picture. A standard flight controller runs each side, but the computer but each is programmed to be 90/180/270 off axis, so when you’re holding it level, every single side is leveling itself offset and related to it’s location on the side of the cube its on (Airmode on). When you change inputs on your stick, that goes to the flight controller int he center, the mixer if that’s what you want to call it, that sends out the individual commands to each flight controller of each quad on the sides.
The downside of this arrangement is what you’d get with a lot of these type arrangements… a lot of dirty air and thrust passing through the center.
Other fun geometric 3D shapes, that are even better than a cube:
That 8 or 12 side ones look promising…

THIS GUY did it 6 years ago
freaking a joy to see all these people in FPV trying to make sense of something that is based on an ideological perspective.
this whole concept is based on the perception that gravity is not a force.
I know many of you guys, are not physics driven people and instead are likely being dazzled by Terrence Howard and literally takes this with a straight face but c’mon guys, the whole Lynchpin is from the aspect that gravity is an effect, not a fundamental force..
but whatever I don’t wanna pop your ballon.. knock yourself out and polish that turd until it shines.. hopefully somewhere down the line you will look up and ask yourself. does it make sense and is the messenger actually solid..or are we being taking for an ideological ride.
Terrence Howard is a freaking good actor, like him, a lot (as an actor) as a person, its more variable, not leats all his remarks about female hygiene, and they are disgusting if they don’t use wet baby wipes. (I won’t judge, as I don’t know what kind of females he has been around, and their hygiene)
Money talks. If this guy drops $200k, it’ll fly.
