Just thought I would jot down a bit about my latest project, that I am messing around with in my spare time
Inspired by the MotoGP cameras, I decided to build my own gyroscopic camera.
Excuse the roughness of it, its a very early prototype at the moment.
Custom made single axis mount, with a single brushless motor, martinez gimbal control board, with different software, Lipo battery, and about 10 hours of programming.
Still needs a lot of software work and some more work on the mount etc.
nice to see that other people also work on something like that
I’m also switched to the Brushless-Thing but I’m still working on a nice housing an a bit of software-optimizing.
Last year I was working with an American Guy on a Servo-Based version … unfortunatley I’m not a native english speaking-person - so my Facbook-page is in German https://facebook.com/MotorradGyrocam
but there is a english project-site available also: http://revenanteagle.org/checksix/gopro-gyrocam
I guess the Brushless-Motors in combination with those Gimbal-Boards acting much faster … so We decided to give them a try too …
But the housing has to be done before we will publish more details
I was a little surprised by that too, I assumed gravity did it. I guess centrifugal force comes in to play at speed and wouldn’t actually stay level with the horizon?
Looks awesome though. When you go into full production, please let me know
i gues you mean the difference betrween a mechanical system compared to a electronic system?
if so, the mechanical (or fluid based) system will always be affected by the lateral acceleration / centrifugal force - so it will not work at all as long as you don’t combine it with a gyroscope
and a mechanical gyroscope would be much more complicated to integrate - you won’t have a heavy block of metal on your gastank - even if - the mechanical gyroscope must be canstantly turned by some force
which will be electronical too thus it is much cheaper and easyer to realise with existing IMU’s - they are realy cheap now … because the are build in a big amount since every smartphone and gamingstation used them.
the wohle electronic (microcontroller, imu, servo, accu) costs less the 100€ - the biggest part ist always the housing - as long as they don’t get produced in china
we dont want to commercialize this - the market is not so great and we have regualr job’s to do
I do build a couple of servo driven boxes in the last month - but I can not give any kind of guarantee since every box has to be seen as a prototype.
the only thing I can offer is trying to repair it if possible - thus … not much people want to spend 250€ for a box which can be defective after a couple of weeks
If you want one - and you can accept that there is no guarantee, and if you are willing to make a interim payment — just send me an email
but look at the videos before (also on my facebook-site) and notice that it don’t works perfect all the time - it just works
some examples where you can see that sometimes it cant follows … but it recalibrates itself on a straight
Been super busy at work and home and not had time to update this, however a bit of progress has been made, software is dialled in now, although am waiting on some replacement parts due to my own stupidity. I have made a couple of revisions of the hardware mount. It is now completely different from the original pics, mainly as I have decided to make the mount fit with the standard gopro mounts and a choice of standalone battery or hardwired, the vid below is it attached to my gopro suction mount attached to my tank.
The advantage of this is that it can be used pretty much anywhere, side fairing, rear, tank etc.
I also want to try if it will be able to mount onto my chest harness for the bike and mountain bike. Once I am back up and running I will get some decent footage.
it’s only gyro-/accel-sensor driven with a brushless motor - no gps at all
it can be powered by the motorcycle-battery or a 3S LiPo-accu
it’s not for sell (at least now) … I’m not completly satisfied with the result for now - I hope it will work better after some more tests.
The Materials costs about 150€ - but the investments to get to this point where (very) much higher
I guess I’m willing to sell one of my 3 prototypes for … let’s say … 250€ … but I also guess you should wait until someone (maybe me) get’s it to work out a bit better
unfortunately not yet … I will post the details later on …
once the cam works out better I will try to sell 20 of them to (hopefully) get some of my investment back
after that I will publish all the details to let the crowd make it even better
it should be done in a few weeks - so please be patient
