Hi Airic,

Many thanks for moving this to the right area - I posted it then spotted the right place after but couldn't figure out how to move it!

Anyway, first of all thank for the support you provided previously and all the countless hours you've spent putting the MiniE project together. Its a fantastic feeling to go out in the countryside and see it all up and running Tongue

The little video above was shot in RAW - I don't think I can do RAW-S - is that a Nikon option? I use a Canon 550d. There was 300 photo's which just about squeezed onto a 16gb SD card.

I used Lightroom and picked a RAW file from the middle of the footage (almost at random) then applied the settings to the rest of the photo's so I don't have to edit each frame individually. Then imported the whole image sequence into Premiere Elements to render.

One thing I have found, is that if I have the camera set on automatic focus, when the arduino should tell the camera to 'fire', it just focuses, then doesn't take the photo. However, if I pre-focus then switch to manual it 'fires' every time.

The attached pic is the rail in my workshop - the legs were found on eBay and cost £25 from China. They were designed for a named 'production' rail - the name of which I can't remember at the moment - with a bit of fabrication work with some 3mm aluminium sheet they now work wonderfully.

Chris.

Hello Chris,

I use a Canon 7D and it has the RAW-S option. Regarding the development of all frames including setting-transitions, I suggest you have a look here:

I never use the camera in auto-focus mode - This leaves to much risk as auto-focusing is never perfect. It would be a shame to have 300 frames and 5 of them are out of focus. And as landscape photography is often wide-angle photography, this also means is has pretty much perfect focus from close to distant objects.

Your track looks really good! It would be cool if you could find the distributor of the legs again though! Wink

Hi again Airic,

I've dug out the old ebay confirmation message on my computer - the legs I'm using is actually for a commercial rail system called a Konova - I've never really heard of them before. The complete rail plus legs with the dolly from this company can total up to £450 (GPB), so being able to buy the legs for just £26.99 (GPB) seems a bit of a steal!

This is the link from the UK eBay site: HERE

These are the exact one's I have used.

I've attached some pics of how the legs can attach to the makerslide aluminum molding I used. I used a sheet of 3mm aluminium which I bent at a 90 degree angle. The screw thread is a 1/4" thread and once I found some correctly sized nuts at a local hardware shop, managed to pick two up for next to nothing. The nut's themselves fit perfectly into the middle space of the aluminium rail wich allows you to tighten the red circular screw's on either end without the nut spinning behind (very lucky). The legs sit flush to the end of the rail and are very secure & sturdy.

Hope this helps anyone who is looking for something similar.

Here's what I got so far as the track and Dolley is concerned. Still have to get the electronics, ball head, motor, and battery on the Dolley.

Here is the third and final update. Couldn't thank you enough Airic! Next steps will be to add the second motor for another movement. Haven't decided what movement it will be, but leaning toward a lens zoom motor. Hope these updates help people and inspire more builds.

Thank you for sharing your building process! I hope it will perform well and produce some amazing footage.

Here is my 6 Axis Dolly Using Maker Slide. The stuff is pretty rigid and not to expensive. It has little rolling resistance and the way I made the Dolly I can hang it upside down too.




Right Now I am using DragonFrame but would like to switch to MiniEngine2 once I can control more than two motors.

Hello Donny,

Your dolly looks pretty impressive!

I am basically done with the implementation of the communication-library for daisy chaining. The next release will contain the Windows software for creating complex multi-keyframe shots (just like DragonFrame). The release after that will contain the daisy chaining for being able to chain multiple controllers and thus control up to 15 miniEngines simultaneously. Each one of them is controlling 2 motors. I cannot tell when but I guess the daisy-chaining-release will be released late summer.

Cheers,
Airic

Here's an overview video I did for my youtube channel with one time lapse of us staining our cabin and at the end three short star time-lapses... I'm planning on doing a couple of videos over the next week or two going over the system in more detail...
