gimbal

Pronunciation: /ˈdʒɪmb(ə)l

Noun:    A device for keeping an instrument such as a compass or chronometer horizontal in a moving vessel or aircraft, typically consisting of rings pivoted at right angles.

Origin:    Late 16th century (used in the plural denoting connecting parts in machinery): variant of earlier gimmal . itself a variant of late Middle English gemel ‘twin, hinge, finger ring which can be divided into two rings’, from Old French gemel ‘twin’, from Latin gemellus . diminutive of geminus .

Ah …. don’t ya just love a bit of ed-u-cation! Yes folks, the word of today is ‘gimbal’ and after a bit of thought yesterday morning, I got mine out and played with it.

So what does this gimbal-thingy do then? Well, in a nutshell, it holds a GoPro camera perfectly steady in pitch and roll while the mounting point is moving around. These things are intended for use on drones, those multi-rotor helicopters that you see flying around, but one look and the old grey matter kicked in …… wouldn’t that be fun on a bike!

And that brings me to yesterday morning, a half-hour blitz in the barn had a mounting plate made and another half-hour had the whole thing fitted, wired up and tested on the left hand crash-bar – which isn’t too bad given that the gimbal has sat in its box since delivery two months ago.

At lunch time the start-up routine was well under way …… pat down the pockets ‘testicles, spectacles, wallet’n watch’ – check . key-on and wait for the dash to finish its self-test – check . fire up the motor and before the gloves go on – camera to record! And this m’dear Smurfletts is an edited video of ‘Tarot Gimbal Test 1′ – I like the sound the front disks make at the end of the video!

Now the keen eyed among you will notice that in bends – especially constant radius bends – the camera begins to roll in the same direction, and this had me stumped for a while. I thought it might just be settings in software, but not being sure I decided to sleep on it.

In the end I think it’s to do with the fact that ‘verticle’ changes when the bike is in equilibrium in a turn (the whole ‘leaning’ thing) and this tricks the sensor into believing that ‘up’ and ‘down’ have moved – so the camera begins to tilt into the turn. Anyway I hope you enjoyed watching some or all of the video as much as I did filming it!
