The bike is of a recumbent design, featuring a relaxed riding position well suited to the sophisticated nature of a steam-powered vehicle. Sporting a wooden frame, the build carries a strong steampunk aesthetic. The flash boiler packs 100 feet of copper pipe, and there’s an electric pump and controller to handle water delivery from the stylish brass tank. The setup is capable of producing steam within 30 seconds of startup. Motive power is courtesy of a 1.5 inch bore single-cylinder steam engine, connected to the rear wheel via a belt drive.
His setup is a little lashed together, but works it’s a throwback to electricity generation of old and deserves the steampunk moniker. A steam boiler drives a steam turbine, which turns a motor, generating electrical power. This feeds into a regulator and a bank of capacitors that smooths the voltage out to a nice even 5 Volts, which powers the Pi.
It’s not exactly efficient, but running the steam boiler using two propane blowtorches sure makes us grin. Usually we see people trying to go the opposite direction and power their projects with renewables. We can appreciate this for what it is too, and it’s certainly not the first time we’ve see a Raspberry Pi burning through electricity for little apparent gain.
It’s sometimes hard to believe how stuff was made over a hundred years ago when electricity wasn’t widely available. One of the most common ways of powering tools was via belt drive — powered by a water mill, or a steam engine, or even horses. [David Richards] has spent a good chunk of time making his own period accurate steam powered machine shop — and it’s fantastic.
It represents approximately what a 1920’s machine shop would look like in America. Not a single tool is newer than 1925. The whole shop is powered by a line shaft using steam power. A massive boiler provides steam for a Pennsylvania built 5 by 5 steam engine, dating back to approximately 1895. Using belts and clutches, it powers a few lathes, drill presses, a mill, and even a shaper — an identical machine to one in the Edison Museum!
[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.
Apparently our Russian brethren have some issues ordering things online. Their shipping solution? A bit of remote social engineering. Thanks to the nature of Russian addresses – that is, the language is pretty easy to recognize – they’ve found that putting down their address in Russia along with a Canadian zip code will usually result in the package being forwarded along thanks to the thoughtful Canadian postal workers. Thanks [Jock]
Social engineering not your thing? OK, well here’s a few extra hacks to chew on. [Sam] thinks you should wrap your electronics in a condom to keep em dry. If you’re in NY, you might want to check out the circuit bending festival. Oh, and if you’ve had your head in the sand, you might have missed the steam powered R2D2.
