I want a machine that could do this will all types of Lego. I've got a 25 lb box of Lego pieces in the garage I'd love to get sorted into little plastic bags.
I've seen way too many "How It's Made" episodes... He needs some sort of vibrating table, and a high speed belt with a "jump" of some sort to combine with those air cannons.
Some problems that you will run in to:
- the timing will need to be very precise
- you will likely need sensors before the stations
- Lego bricks come in all shapes and sizes and will respond unpredictably to air currents
- you will need a way to arrest momentum or they'll shoot right back out
Still, this is orders of magnitude faster than my contraption if you can get it work.
And film every single test run and failure. I would subscribe to this Patreon!!!
