Have always been interested in drones, but didn’t want to just buy a retail one that just fly’s with no modification ability. So the one below looked interesting using micro:Bits and I bought one.
My first impression when I opened the package was; is this all I get for $259. IMHO I think this product is overpriced. It comes with no instructions, just a piece of paper pointing to the web site. The web site has the bare basics to get it to fly, literally no technical information. Yes I probably should have researched it more, maybe I could have just started from scratch maybe there are better products out there. Anyway …
It fly’s if you load the code from the web site, but not very well. It seems to have no inbuilt hover or stability. It simply moves as the controller moves; it is very easy to get out of control as a slight movement of the controller moves the drone significantly. And you tend to overcorrect.
So I started to investigating the code. Pitch, Roll, Yaw & Throttle are sent from the micro:Bit to the control board via a serial string. I changed the controller to send just Throttle, no other movement commands. It lifts off and drifts in one direction quite fast indicating the control board is simply adjusting the motors related to the commands it receives. So any stability would have to come from the micro:Bit; but the web site code did not have any built in. It looks like they may have been going to as there is a variable called Autopilot, but it does nothing.
I am happy to try to develop stability software. But, I would like more information on the control board, what do all the lights mean, why is one flashing. How is P0 used to detect battery voltage and charge conditions. I have done some research measuring the voltage on P0 and displaying the level calculated by the code, but still not 100% on it. Some form of basic schematic would help.
I know what I am asking should be directed to the manufacturer and I will do that in time.
Would like to hear from others who may have purchased this product and their experience.
PS I will keep investigating this product and place what I find here.
PS This is for Core Electronics. The control board antistatic bag had been opened before I received the product. The control board works … like I think it is supposed to … but …
