![Pi-Fest A Project(s) The oh good lord did I really start this project, I am going to finish it! [Blog 5]](https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/blogs/components/weblogfiles/00/00/00/03/67/4705.2_missionpatch.PNG-1440x400x2.png?sv=2016-05-31&sr=b&sig=kBbHbQov922HbM5iE0Izcl9oOSB3Q5lw3L%2B5b%2F%2FBPZs%3D&se=2025-09-12T23%3A59%3A59Z&sp=r&_=XNXHVTvngNW0FL1HWc3elA==)
The parts - so far.
Lets quickly touch on the "design process", it is somewhat akin to the walk and build or design on some paper you had on your desk, more than the lets just play it by ear and see how it goes, but by no means any feat of engineering design. Whilst this may add a little chaoticness to the overall process and only serves to remind me why i am best off working alone, it is also where I am most happy.l Needing to have something to think about, to do, to draw, plan, design in mind is what makes me tick.
For all the parts so far the approach taken has been a simple 3 step process.
1. What do i need? do I already have it?
2. I dont have it, can I design it and 3D print it?
3. Do i have something I can repurpose, recycle, reuse, or do I need to buy?
I have mostly ticked 1 and 2 above. The seperatelyt puchased parts are the Pico Pi, capacative touch sense input 12 channel board and some super touch sensitive materials.
I like white PLA, I can compost it, i can seal it if I want or I can paint, does the trick for me!
I have attached the STL files for each component which needs to be 3D printed. If you want the original design files which were prepared in Fusion 360 please let me know and I can also load these (once i have downloaded from the Fusion Cloud - wherever that is :D)
Parts in motion
Video description: As the main drum rotates, the 30mm peg runs up the back of the tipper mechanism to the point it causes it to pivot. The travel at the bottom end of the tipper mechansim travels further than the displacement at the top, which moves the BB holder base to release a single BB which immediately drops to the keyboard below.
Video description: The single BB which immediately drops to the keyboard below, from one single corresponding pin scales upwards to a max of 10 drops per time step / interval / or drum bar. With no external sound source it makes a curious clink and then drops to my bench and rolls off .. somewhere [to do: catcher tray which feeds to the lifter gear to restock the bb holders]. Added bonus of keyboard movement demo and rest of construction in frame.
Still to do ... a lot.
