Hackaday Podcast Ep6 – Reversing iPod Screens, Hot Isotopes, We <3 Parts, and Biometric Toiletseats

Posted on by

What’s the buzz in the hackersphere this week? Hackaday Editors Elliot Williams and Mike Szczys recap their favorite hacks and articles from the past seven days. In Episode Six we cover an incredible reverse engineering effort Mike Harrison put in with iPod nano replacement screens. We dip our toes in the radioactive world of deep-space power sources, spend some time adoring parts and partsmakers, and take a very high-brow look at toilet-seat technology. In our quickfire hacks we discuss coherent sound (think of it as akin to laminar flow, but for audio), minimal IDEs for embedded, hand-tools for metalwork, and …read more

A Crash Course In 3D Printed Venturi Pumps

Posted on by

Venturi pumps, commonly referred to as aspirators, are a fantastic way of moving around things which you might not want spinning around inside of a pump, and one of the easiest ways to create a vacuum. According to his research, [Tuval Ben Dosa] believed such a device would be a good way to move corrosive gasses which would normally eat up a blower fan; all he had to do was figure out how to 3D print one to his specifications.

Put simply: if you take a “T” shaped pipe and pass a fluid (such as air or water) through the …read more

Feed the Fun with a Semi-automatic Cheesy Poof Rifle

At Hackaday we think that hackers have the power to make the world a better place with their builds. This air-powered cheesy-poof rifle is not one of those builds, unless making the world a little more fun and slightly messier makes it a better place.

The principle of [NightHawkInLight]’s design is simple – an electric leaf blower provides the power, and a big vat o’ poofs provides the ammo. Getting the two together and providing a barrel is a matter of some simple plumbing with 1″ PVC pipe and fittings. But wait – lest you think this hack, like the …read more
