Delightful Electromechanical Build Of A Jet Engine Model

[InterlinkKnight]’s jet engine model is a delight to behold and to puzzle out. Many of us have been there before. We know how to build something, we know it’s not the most up-to-date approach, but we just can’t help ourselves and so we go for it anyway. The result is often a fun and ingenious mix of the mechanical and the electrical. His electric jet engine model is just that.

Being a model, this one isn’t required to produce any useful thrust. But he’s made plenty of effort to make it behave as it should, right down to adding a …read more

3D Printed Airplane Engine Runs on Air

One of the most important considerations when flying remote-controlled airplanes is weight. Especially if the airplane has a motor, this has a huge potential impact on weight. For this reason, [gzumwalt] embarked on his own self-imposed challenge to build an engine with the smallest weight and the lowest parts count possible, and came away with a 25-gram, 8-part engine.

The engine is based around a single piston and runs on compressed air. The reduced parts count is a result of using the propeller axle as a key component in the engine itself. There are flat surfaces on the engine end …read more

The Last Interesting Rover Had A Gas Turbine Engine

If you have a car parked outside as you are reading this, the overwhelming probability is that it has a reciprocating piston engine powered by either petrol(gasoline), or diesel fuel. A few of the more forward-looking among you may own a hybrid or even an electric car, and fewer still may have a piston engine car powered by LPG or methane, but that is likely to be the sum of the Hackaday reader motoring experience.

We have become used to understanding that perhaps the era of the petroleum-fueled piston engine will draw to a close and that in future decades …read more

Hackaday Prize Entry: Engine Control Units and Arduinos

The modern internal combustion engine is an engineering marvel. We’re light-years ahead of simple big blocks and carburetors, and now there are very fast, very capable computers sensing adjusting the spark timing, monitoring the throttle position, and providing a specific amount of power to the wheels at any one time. For the last few years [Josh] has been building a fully-featured engine management system, and now he’s entered it in the Hackaday Prize.

The Speeduino project is, as the name would suggest, built around the Arduino platform. In this case, an Arduino Mega. The number of pins and PWMs is …read more

Casting Cylinder Heads Out Of JB Weld

Like friendship, JB Weld is magic. Rumors persist of shade tree mechanics in the Yukon repairing cracked engine blocks with JB Weld, and last month this theory was proved correct. [Project Farm] over on YouTube took a grinder to the head of a lawnmower engine, filled the gouge with JB Weld, and ran the engine for twenty minutes.

However, as with anything mechanical that doesn’t have a foul-mouthed Canadian in it, arguments ensued. ‘This was not a true test of JB Weld repairing a cracked engine block’, claimed Internet commenters, ‘I won’t even watch the video because the idea alone …read more

Coke Can Fueled Power Generator

[Experimental Fun] shows us how you can create a cola power generator that runs on nothing more than cans of cola including the container and a little bit of sodium hydroxide to speed the reaction up.

This might sound a bit crazy, but it seems you can power an engine on little more than your favorite fizzy drink and the cut-up remains of an aluminum can. What happens is that aluminum and water create a chemical reaction when mixed together, which gives off hydrogen. Normally this reaction is very slow and would take years to make any noticeable marking on …read more

Easy Free Piston Stirling Engine

Stirling engines are really cool machines, invented by Reverend Dr. Robert Stirling in 1816 to rival the steam engine, they are one of the most efficient engines ever conceived.  Building one is a very rewarding experience, but it has a certain level of difficulty. However, [Attila Blade]’s version of a free-piston type Stirling engine is simple enough to be built in a matter of minutes.

To build the engine you only need a test tube, steel wool, a latex glove, an O ring and some wire. The construction is straightforward as you can see in the video. The whole engine …read more

Cordless Drill Uses no Electricity

There are few projects on how to make your own cordless drill, but what sets [Johnnyq90’s] amazing project apart is the fact that his power plant is a nitro engine. Not an easy task of course, but he makes it look easier than it is, and we really enjoyed the construction process.

He uses an RC Kyosho GX12 engine that was previously modified, changing the cooling head with a larger one. The engine drives a gearbox that was taken from another drill. All other parts were hand made. The clutch was carefully machined, and the cooling fan was made in …read more

Miniature Engine Model Made Of Paper

You can make a lot of stuff out of paper, but a single-stroke engine model less than an inch across? That’s a new one, courtesy of Russian hacker [Aliaksei Zholner], who built a quite remarkable model of a single-stroke engine out of paper (in Russian, translated version via Google Translate). Measuring less than an inch across, it is driven by compressed air and accurately models the rotary action of a single-stroke engine, where a piston in the cylinder drives a flywheel that creates the engine cycle.

The creator has managed to run it at up to about 60 revolutions per …read more
