Fresh hacks every day
Turning 3D printed plastic parts into metal objects is not a new concept. But we don’t see a lot of it and enjoyed watching the documentary version of [3DTOPO's] lost PLA metal casting process so much we figured you’d want to see it too.
The thirty-five minute video walks through every part of the process which we originally learned about … Read the rest
If you want to do casting at home, you’ll need a way to melt metal. [Jake]‘s DIY foundry furnace gets hot enough to melt aluminium, and is built out a mix of scrap parts.

He wanted to replace his older furnace with one that was more efficient, and to that end he built a heat exchanger into the design. This way the exhaust will preheat the intake air.
The furnace itself started with … Read the rest
Did you know it’s possible to write Javascript code without using any letters or numbers at all? Well, it’s not just Javascript, but that’s the language used in this demonstration. [Patricio Palladino] shows how code can be written using just eight characters, and all of them are punctuation marks.
Typecasting is the name of the game here. By starting … Read the rest
