Here is a screenshot of the first prototype plan from top and side views.
The overall dimensions are 11” height and 13 3/4” outer diameter.
Bill of Materials:
- plywood: TBD, scraps could do if you can make segmented turnings, outer shell can be a pyramid or a cone
- motor: $10
- power supply unit: $10
- Lazy Susan bearings: $4.50 plus postage (or get them at your local DYI store)
- misc electric stuff: depending on the command mode. If RC, add around $20.
- add the cord of course :)
so far, for the motorized function, we’re around $40 give or take.
Time wise, I’ll have to actually build it to be able to give a decent value, but this part will depend on the technique chosen for the cylinders (bent lamination of cheap veneer, segmented plywood turning, or even a mere octagon or other high facet count thing).
Now to end packing up for the 10 hour road trip tomorrow… TTYL
