Second grade science project: a steam engine

2nd-grade-steam-engine

If you’re looking for a way to let the kids get hand-ons with science this is a perfect example of how to do it. [Erich] wanted to help out with his 7-year-old’s science project. They decided to build a working model of a steam engine but couldn’t find online instructions appropriate for the age group. So the two of them … Read the rest

High powered rocket engines made from PVC pipe

rocket

For as much as we enjoy rockets, explosives, and other dangerous things, we haven’t said a word about the works of [Richard Nakka]. He’s the original hacker rocketeer with thousands of words dedicated to the craft of making things move straight up really fast. One of his more interesting builds is his series on building rocket engines out of Read the rest

Land speed baby carriage record set at 53 mpg

53-mpg-baby-carriage

Let’s face it, you’ll never break the motorcycle land speed record without a stellar engineering team and some serious corporate sponsorship. But this build proves that individuals can still set other speed records. [Colin Furze] rode his motorized baby carriage over the 53 mile per hour mark to set a the world’s record. We were surprised to learn it only … Read the rest

Retrotechtacular: Fluid Coupling

retrotechtacular-fluid-coupling

We realize the transmission fluid of an automobile’s automatic transmission is used to transfer the power from the engine to the drive shaft. But after watching this Department of Defense video from 1954 we now have a full understanding of the principles involved in fluid coupling. Like us, you probably have seen a diagram of a transmission which shows … Read the rest

Almost building an engine from hardware store parts

engine

You can build a surprising amount of stuff from parts you can pick up at a hardware store. Sometimes, though, getting a project built from sections of pipe is very, very difficult. That’s the case with [Lou]‘s hardware store engine: despite an inordinate amount of cleverness, he just can’t seem to get an engine made from pipe fitting to … Read the rest

FUBAR Labs builds a rocket engine

engine

[Graham] over at FUBAR labs took it upon himself to build a rocket engine. This isn’t a simple solid-fuel motor, though: [Graham] went all out and built a liquid-fueled engine that is ignited with a spark plug.

The build started off with a very small ‘igniter’ engine meant to shoot sparks into a larger engine. This engine is fueled with … Read the rest

3D printing a rocket engine

Most any rocket engine you’d find on a spacecraft – save for solid or hybrid rockets – use an engine system that’s fairly complex. Because of the intense heat, the fuel is circulated around the chamber before ignition giving a motor its regeneratively cooled nomenclature. This arrangement leads to a few complicated welding and machining processes, but surprisingly these obstacles … Read the rest
