Magnetic Hourglass final (3rd) day

Towards the end of my time in the workshop it became clear although the structure was moving, I had to do compromises from my initial plans.

In the beginning  of the day I had a working band to move the magnet. After going over couple of possible arrangements for the final looks and decisions.

 

I chose the band to carry a metal ball every 5 sec to still call the structure hourglass but not to take too much time of a viewer to understand the motion in final presentation. 

After screwing the main internal structure that carries the band to wooden panel I hot glued the slide and stopper pieces and created this pointy ecstatic.

The main problem whit the magnet and metal balls is Its hard to make sure it gets only 1 ball and not 2 but I found out that to be this perfectionist in this not that perfect machine is pointless since magnet taking 2 balls is no way harmful for the machine.

In future I will have to add batteries to the hourglass since its  costly to have the right power box. And I will add more magnets to the same band instead of trying to add more bands to same motor which will add more movement.

Magnetic hourglass day2

After trying to add the second moving magnet, I had to change the final product to use 1 magnet mainly because of time limitations.

In 3rd day I will assemble the inner structure with the woods I cut. And make a plastic casing.

Magnetic hourglass Day 1

Summary: As planed, first belt that cary magnet is working now. 

Tomorrow I will have to make the second belt which hopefully use the same motor, chose how they will be places in the structure and chose the outer material which will effect the magnets power to carry balls.
