Re: Chocolate Powder Sintering? - 11 years ago
Do you guys think a laser diode pulled out of a DVD burner would work? Joe that's definitely an interesting idea, but I'm not sure how thin you can make the walls while maintaining structural integrity.by oatmonster - General
Re: Chocolate Powder Sintering? - 11 years ago
Thanks, I'll look into burning laser diodes! I'm not too concerned about how getting great tasting chocolate at the moment. Right now, I'm more worried about getting a powder that will melt well. They seem to be using straight cocoa powder right now, and although it's easy to get, it doesn't contain any cocoa butter, so I can't imagine getting anything with a texture like regular chocolate.by oatmonster - General

(Here's a video: ) What kind of a laser would it take to melt chocolate powder?by oatmonster - General
External Gear Pump - 11 years ago

Right now it pumps pretty well, but there are some major leakage issues around the threaded rod that serves as the driven axel. Chocolate syrup video: Water video:by oatmonster - Look what I made!
