We got a Pizza oven! …and this time-lapse film of us building the stand for it is made using a little dolly unit I built for our GoPro. We’ve always wanted to have a simple small unit to plonk on a table during breakfast and slowly trundle forward, but such a device simple doesn’t seem to exist. So making one seems to be the only option.
Here’s a few prototypes:
First I tried building a little winch with a super geared down motor, and a trolley for the GoPro made of Lego. It worked, but it was cumbersome, and tricky to set-up.
Then I put the winch on the trolley and used it to power the wheels. Much better, but it was too fast and a bit noisy.
For the final design (although I’m sure I’ll tweak it again), I rebuilt the motor and gears using an old Lego motor and all the cogs I could find in our Lego box that’s sat in the cupboard since we were kids. Now it’s super slow, and the Lego motor runs almost silent. Oh Lego, is there nothing you can’t do?
I know what you’re thinking, you’re thinking “But what does it look like if you strap an infrared filter to the GoPro and set it off on it’s jolly way down the garden path?”. Well it looks a bit like this:
Here’s the brave little soldier in action:
