[RimstarOrg] has posted an awesome writeup on his Hero’s steam engine . Hero’s engine is a Greek design from the first century and is the earliest known steam engine. It’s amazing to think he developed the engine seventeen centuries before the industrial revolution, and yet it was largely ignored. While you can find more faithful replicas, of this landmark machine [RimstarOrg]’s rig can’t be beaten for simplicity and he does a great job of explaining the principal of operation and construction.
Using a soda can filled with water and a propane torch [RimstarOrg] was able to get the can to rotate rapidly by ejecting steam from two holes in the side of the can. A fishing swivel is used to provide a pivoting joint and allow the can to rotate freely.
While we’ve covered steam engines before, we loved this simple design, and can’t wait to see what [RimStarOrg] comes up with next.

Steam power anything these days is pretty cool, but rarely have we ever seen such a complex build as this steam powered, remote controlled 1/16th scale tank.
[Ian] is an electronics design engineer whose hobbies include messing around with steam power. The Steam Turret Tank is based on a 1/16th scale Tamiya King Tiger die-cast model tank. It features a 3.5″ diameter marine boiler from MaccSteam, which is a fully equipped miniature version of a real boiler, complete with pressure gauges, safety valves, and a ceramic burner. It can produce pressures of up to 70PSI (max 120PSI), but for this project, [Ian] is limiting it to around 30PSI.
A small 2″ diameter fuel tank contains a propane mixture to fuel the boiler. Two Regner 40451 Piccolo steam engines make up the drive train, with mechanical linkages controlled by servos to engage the various features. The tank can go forward, backward, spin in place, and the turret can both rotate and adjust trajectory. It also has controllable headlights, and can even “fire” the turret.

The photo above doesn’t do this huge and whimsical Steampunk Battleship justice. It’s an amazing project that took its creator, [Ed Ross], over 2500 hours to complete.
Called Barnum’s Dream, it was said to be originally commissioned by Queen Victoria as a ship for the Crimean war, and was the largest paddle wheel steam warship ever built. It was then retrofitted with a massive train carriage to be used in the Franco-Prussian war (that’s right, on land!).
The model is just over 4 feet long and just under 4 feet tall. Aside from the steam engine (which was modified) it was completely build by hand. Almost all of the mechanical linkages and powered by the internal steam engine. The level of detail that went into this is absolutely awe-inspiring.
If you enjoyed the background history of the ship, there’s a delightful tale of the ship’s apparent origins on [Ed’s] blog which is thoroughly enjoyable. Make sure to check it out after watching the video after the break.

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 not only pulled off the build, but then they wrote a guide for others to follow. The thing about it is, you really have to understand a concept to teach it to someone else. So we think the write-up is equally important to having actually done the experiment.
Steam can scald you if you’re not careful. But you don’t really need steam to explore the concepts of a steam engine. The main reason to use steam is that it’s a fairly rudimentary way to build pressure which can be converted to motion. For this demonstration the blue balloon provides that pressure. It’s feeding a reservoir that connects to the valve built out of straws. A plastic piston inside pushes against the crank shaft, spinning the cardboard wheel on the left. When the piston travels past the valve opening it releases the air pressure until the machine makes a revolution and is in place for the next push. This is well demonstrated in the clip after the break.

[Valve Child] has been building a few three-string cigar box guitars. Of course he’ll need a few pickups, but three-string guitar pickups aren’t exactly easy to come by. To solve this problem, he’s built a guitar pickup winder powered by a steam engine.
The pickup winder is powered by a Wilesco D20 model steam engine, connected to the actual winding mechanism via a rubber belt. To the right of the bobbin bracket is a mechanism built out of Meccano – Erector sets for us americans – that provides a mechanical counter for the number of wire turns and a wire traverse to keep each layer of wire somewhat even across the width of the bobbin.
Previously, we’ve seen [Valve Child]’s really sweet sounding lap steel build from a log using a hand-wound pickup and a preamp tube as the bridge. It’s questionable if the guitar signal came from this lap steel via the pickup or the microphonic tube, but now [Valve Child] has a really, really good method of improving his pickup production abilities.
Video after the break.

This hurts our head
You know you can ‘freeze’ drops of water in mid-air by flashing a LED at the right time, right? Well, according to this video you don’t even need a strobing light; just use the frame rate of the camera. Much cooler if you don’t know how it works, in our humble opinion.
Now do Junkyard Wars!
[James Cameron] and [Mark Burnett] (the guy who created Survivor) are bringing Battlebots back to the Discovery Channel. The new show is called Robogeddon and calls upon the current talent in the fighting robot world. Our prediction? Someone is going to build an amazing piece of art that will be completely destroyed in the first round; a wedge with wheels will take the championship.
A steam engine made out of rocks
[Hansmeevis] just spent 230 hours hand carving a steam engine out of gems. It’s called “Dragon’s Breath” and it’s an amazing piece of work: the cylinder is carved out of quartz, while the flywheel, mount, and base are carved out of jasper, onyx, zugalite, and other semi precious gems. Amazing artistry and it works.
Don’t lose a finger on all that science over there
[Dr. W] is a science teacher in Saint-Louis, France. Next year, his students will be learning about reaction propulsion and impulse conservation. To demonstrate these properties, [Dr. W] hacked up an old vacuum cleaner in to a jet engine and built a Pitot tube to measure the 140 km/h wind speed. Google translation.
Circuit bending a Sega Saturn
Making cool glitched-up graphics from Ataris and Nintendos is old hat, but not much has been done with circuit bending slightly more modern consoles. [big pauper] found his old Sega Saturn in his grandma’s attic and wondered what secrets this forgotten box held. It turns out he can make some pretty cool sounds and even cooler glitched out graphics. The pic above is from Virtua Fighter; done correctly these glitched low-polygon graphics could easily find themselves in a very stylistic indie game.
Usually we don’t like to feature projects that have zero build details, saving them instead for a links post. But this steam-powered bicycle is too… peculiar to pass up. In between the rider’s legs is the firebox that contains a wood-fueled fire. Watch the clip after the break and you’ll find just how noisy this contraption can be. In addition to the mid-range “chug-a chug-a” there’s also the constant whistle we’d attribute to the pressure regulator. It’s surprising that the whole bike doesn’t heat up, but it must not be all that bad since the test pilot isn’t wearing asbestos pants. All kidding aside, it looks like this beast has no problem getting up to a running pace (based on the movements of the camera) and that’s thanks to a renewable energy source.
We’d be much more comfortable seeing this in a mechanized tandem form factor since we just can’t get over having a fire between our legs.
