Step 2: Building The Frame
there are 2 ways of starting up:
1. Screw together two sticks into a V shape. Than do another pair
make sure they come out as similar as possible, for maximum stability .
2. Connect them with one another with a horizontal stick.
When sawing the horizontal piece of wood, you may want to leave some room for the Arduino box, to be attached to it, taking extra 5-6" that will stick from the side.
you now supposed to get two triangles, connected by their vertexes.
See main image for an example of the outcome.
Just buy separately one table stand
it probably makes more sense unless you enjoy any kind of woodwork (like me).
Onto that horizontal stick, evenly attach hinges.
I am such a pretty bad carpenter, hinges are my all time nemesis. I hope you do better.
Attach their other end to the little shelf
yes, that's the last piece of wood on the list -
keep in mind that you should be able to drill a 5mm hole in it's width, so double check you chose a piece thick enough; this hole is going to be used for the round pole that is connected to the motor with a fishing line.
Onto the wooden shelf's profile, drill holes for the needed peripherals
* 5mm hole for the stick mentioned above
* 3mm hole for the fixed bubble-making arm
* 2 holes for attaching the fan via screws.
* Depending on the servo's size: Holes for attaching the servo or saw a socket for it, which is what I did (see image 4)
