It took quite a bit more to get to this point, including losing one to a mid-race bump and run from another racer. This is probably at least the 4th or 5th version. Lots of trial and error as well to get the software right. I'm still trying to get the creator to realize that this has massive sales potential for the non-technology inclined, but he rather not deal with tech support as a result. Edit: You also need to modify the contour to remove the o-ring that seals the unit to make it waterproof. Otherwise the friction on the ring that rotates the lens/camera would burn the servo out.

Went for a ride today to play with my new gopro 3 black and try it out on the chin bar of my helmet. I was riding along till I came up behind a group of cruiser jerks and one of them was a lady. I rode behind them for a mile when we came up to a light the lady realized she was in the turning lane and swung back over to the other lane just as the light was changing. She for some reason instead of braking like a normal person decided to jam on the rear brake and skid all the way through the intersection. Funniest poo poo ever, unfortunately the chin bar mount for the gopro caused it to be pointed too far down so I didn't get a good shot of the action but here is what I got on video. https://www.youtube.com/watch?v=ycpyI3BPp5k&hd=1

I would be charging an entirely reasonable amount for assembly and printing (as I'd likely print the parts myself). The first thing I'd be doing is a redesign of the case to support the GoPro, which is no small undertaking, as every local hillclimb racer I know of has a GoPro, and they will undoubtedly want one of these that works with it.

Reminds me of some guys I saw last spring, right as the weather turned all the weekend warriors came out and I saw two guys skid to a stop coming out of an alley onto a well-trafficed side road. I couldn't tell if they meant to do it or they were just bad riders but a car turning into that blind alley at just the right time would have really ruined their day.

Ugh, we're in the middle of the "thawing out" process. Where all the fair weather riders are starting to pull their bikes out of the garage and either wobble uncertainly around the coast or overcook every loving corner. Including the Police riders. Right, to put my 3D printer where my mouth is, so to speak, I bashed these rough designs out last night. http://www.thingiverse.com/thing:71798 Derek used a servo for the motion control, but I want to be able to haul cameras up to the size of small DSLRs or maybe even two GoPros for  3D, so I'm going with a NEMA17 stepper motor; 4.4KG/cm of holding torque, 0.9 degree steps subdivided by 16 with a good stepper driver will give enough resolution for smooth movement (6400 steps per rotation) while allowing fast adjustments, faster than the servo by far. To keep the camera as close to the motor as possible, while allowing the axis of the lens to be adjusted to that of the motor, I'm using a pair of interchangeable low profile dovetail plates which will be locked in place by a grub screw.

 Some test dovetails. The idea is you print however many male/female plates you need and epoxy them together using scrap filament as indexing pegs. There's plenty of space on the camera platform so you can drill different mounting holes for your different cameras. Alternatively print one of these and spend £50 on a pair of 808s  http://www.thingiverse.com/thing:41812 EDIT: Male plate, printed with a scrag-end of grey PLA I had. One of the nice things about printing these plates individually is that you can print them with just a few meters of 1.75mm filament, so I'll have a bunch of fabulous colours by the time I'm done prototyping

That's pretty awesome. I really wish I/we could afford a 3D printer, as it would be completely awesome to be able to design literally anything you wanted. One thing to keep in mind after discussing your project with the original designer is the concern of vibration. A lot of the early issues we had with the camera were the amount of vibration transmitted to both the camera and gyro causing a lot of issues. The gyro issue has since been sorted, however my big worry with your plan is the amount of stress on the servo motor and vibration of the actual camera mount. I saw some other home-built gyrocams at BARF, including one that was using a GoPro. The problem with his was the camera doesn't have a circular mount to rotate like the Contour does. As a result, the camera is mounted essentially on a post coming out of the main unit, making it into essentially a stiff, horizontally mounted pendulum. Hope I'm making sense here. Either rate, I'll be curious to see the end result.

Now that is dragging some kn-  Progress. I dont have anything to clamp these parts so I'll have to epoxy them tomorrow when I can steal some bulldog clips from the work stationary cupboard.  Too big. This is a chunky lump of an ancient D70, it doesn't even do video, I just fitted it up to see. A lightweight entry level DSLR should be no problem at all as long as it doesn't have too much glass hanging off it. That said, I have an idea for an adjustable two bearing lens-steady that could support even heavy DSLRs, working a lot like a travelling steady for on a lathe.  Unrelated. Just a pic that's been on my phone for a week or two because I thought someone on here might get a kick out of it. Local guys decides to build a vintage 2 stroke racer, buys ported-to-the-balls crate engine from a UK race tuner. Takes it to the local garage because he can't get it started. Answer - it's a tuned to the balls 2T race engine, you have to start it with a 4T powered race-starter. I think the guy thought he might pop to the shops on it or something.    Totally restored Greeves trials bike, being used to mark the start of last weeks coastal trials competition.EDIT: Revenant.Eagle posted:That's pretty awesome. I really wish I/we could afford a 3D printer. I couldn't, so I ended up making my own, most of the frame is still made from half inch softwood shutter ply  quote:Vibration... Hope I'm making sense here. Totally. The vibration issue has been looming big in my mind and I've got some ideas to deal with it but I don't want to flesh them out until I've got something together that I can strap to the KTM to gauge how big an issue it will be. The first idea is to use a cantilevered mounting platform to shift the mounting point under the center of gravity. Building some flex into this should reduce it significantly, if not I've got various other avenues to explore. The mass of the bigger cameras may actually help here.

ReelBigLizard posted:Now that is dragging some kn- Rather than fitting a full DSLR, how about micro 4/3 format like Panasonic G-series etc.? The benefit with using cameras with interchangeable lenses is some of the vibration can be accounted for by the active anti-shake built into the lens. I also seem to recall watching a video demonstrating the use of an anti - vibe mat/pad to cut a lot of vibration in a camera mount, but I'll be damned if I can find it now.

Camera antishake (at least the ones I've used) is for very low-frequency stuff - like how your arms move when you hold a camera. If you put a high-frequency buzz like an engine vibration through it, it won't do squat, and the amplitude of any bumps in the road will overwhelm it. I personally would stick to something GoPro / Countour-ish simply because they might hold up better if you crash / camera falls off, while a DSLR and lens are going to explode into a million useless pieces. I'm not seeing artsy DOF doing you much good in these applications anyway.
