It’s just scrap steel welded together with some cogs I got from the dump.My second thought: I wonder how much you could sell the device for.
My third thought: I wonder how much you tipped your assistant. Her body language and the look on her face suggests not much.
Thanks for sharing this posting. I repeat, these are stunning images!This is a video of the Spirograph Jig Thingy I made, it has push bike gears and by changing the gear ratio changes the pattern, also the amount of rotations changes the pattern.
By changing the camera angle gives the different effects on the images.
This thingy was for the first 3 images, the last 2 I used a pushbike wheel with LED's I will post a photo later.
