Make A Steam Cleaner From A Broken Clothes Iron

March 20, 2018 by 2 Comments

As the old saying goes, when life gives you a broken iron, make a steam cleaner. Or something like that. Anyway, [Claudio] from [Accidental Science] had a clothes iron with a broken head that he decided to adapt into a steam blower that can be used to clean PCBs, glassware, degreasing parts or cleaning stains off the couch.

[Claudio] covers everything from tearing down the broken iron to crafting a new tip that avoids problems with water droplets condensing on the brass tip that he used first. After salvaging the switch in the head that controls the steam, he carved a wooden handle that is soaked and coated with high-temperature resin. The hot end was then reinstalled, and the whole thing put together.

This build should be approached with some caution, though: anything that mixes high-pressure steam with electricity has the potential to go wrong in unpleasant ways, so be careful out there.

Smell That? It’s Time.

January 30, 2018 by 14 Comments

Steampunk is beautiful. There is something about the exposed metal and primitive looking artifacts that visually appeal to the brain of a maker and engineer alike. Makers have been busy the last decade building clocks with this theme because hey, everyone needs a clock. [Fuselage] has put together a Steam Punk Clock that releases actual steam(actually steam oil smoke) for its hourly chime. How cool is that?

The clock is designed around the Conrad C-Control Unit (translated) which has the Motorola 68HC08 and [Fuselage] uses BASIC to write the routines for the system. Unlike a lot of steampunk clocks that use Nixie Tubes, this one uses 4 Numitron displays for the hours and minutes display. An analog dial panel display is employed for the seconds’ and is driven by a PWM signal. The absence of the RTC module was not obvious until we saw that the BOM includes a DCF77 receiver. For the uninitiated, DCF77 is a longwave time signal and standard-frequency radio station in Mainflingen, Germany. If you are anywhere within a 2000 km range of that location, you can pick up a 24-hr time signal for free which is excellent if you plan to make say… a radio clock.

The steam/smoke generator is a subproject of sorts. The custom machine is designed to have a separate oil reservoir and pump in addition to the actual generator so that the system does not run out of fuel as quickly. Clearly [Fuselage] did his homework which is explained in brief in his project logs. The final design has a brass tube as the main heating and also serves as the outlet chamber. The oil is pumped from under the heating filament in the brass tube, and excess fluid drains off back into the reservoir. A piece of nichrome wire serves as the filament that vaporizes the liquid to gaseous form. Sensors make sure of the oil levels in the reservoir as well as the steam tube. Servo motors and fans add the effect of the opening the exhaust rain cap, and a small LED helps illuminate the exhaust to complete the impression of real steam.

The project is a great example of a simple but effective implementation and for those who are wondering about Numitron Tubes, check out this tutorial on the subject. Of course, there is the Giant Electro-mechanical Clock for those looking at more sizable works of art.

Sony Unveils Swarm Robots For Kids

June 8, 2017 by 24 Comments

Sony recently unveiled Toio, an educational robotics toy for young programmers. We all know Sony as an electronics giant, but they do dabble in robotics from time to time. The AIBO dog family is probably their most famous creation, though there is also QRIO, a bipedal humanoid, and on the stranger side, the Rolly.

Toio consists of two small cube robots which roll around the desktop. You can control them with handheld rings, or run programs on them. The robots are charged by a base station, which also has a cartridge slot. Sony is marketing this as an ecosystem that can be expanded by buying packs which consist of accessories and a software cartridge. It looks like the cartridge is yet another proprietary memory card format. Is Sony ever going to learn?

There isn’t much hard information on Toio yet. We know it will be released in Japan on December 1st and will cost around ¥ 20,000, or about 200 USD. No word yet on a worldwide release.

The striking thing about this kit is how well the two robots know each other’s position. Tape a paper pair of pants, and they “walk” like two feet. Attach a paper linkage between them, and they turn in perfect sync, like two gears. Add some paper strips, and the two robots work together to form a gripper.  We can only guess that Sony is using cameras on the bottom of each robot to determine position — possibly with the aid of an encoded work surface — similar to Anoto paper. Whatever technology it is, here’s to hoping Sony puts out an SDK for researchers and hackers to get in on the fun with these little robots.

Suffer No Substitutes — The Hudspith Steam Bicycle Is One-Of-A-Kind

June 8, 2017 by 25 Comments

In a bit of punky, steam-based tinkering, Brittish engineer [Geoff Hudspith]’s obsession for steam and passion for cycles fused into the Hudspith Steam Bicycle.

Built and improved over the past thirty years, the custom steam engine uses a petrol and kerosene mix for fuel, reaching a top speed of 32km/h and has a range of 16km on one tank of water. While in motion, the boiler is counter-balanced by the water tank on the rear as well as the flywheel, water pump, and the other components. However, [Hudspith] says he doesn’t have an easy go of it carrying the bike up the flight of stairs to his flat — as you can imagine. A steam whistle was fitted to the bike after insistence from others — and perhaps for safety’s sake as well, since it does take a bit of distance to stop the bike.

Many people have offered large sums for it — and at least one house in exchange for the bike — but [Hudspith] has held on to this one-of-a-kind steam-machine. A little more about the development of the bicycle can be read here! A video of the bike in action is waiting after the break.

The Trouble With Old Model Steam Engines

June 2, 2017 by 13 Comments

Model steam engines have intrigued hackers and makers for over 100 years. Many of us have seen old steam engine models up for sale at garage sales and various internet auction sites. The problem with these engines is the fact that many of them were sold as rough casting kits. This means the quality of the model is only as good as the original owner’s machining and fabrication skills.

[Keith Appleton] is something of a steam engine expert. In this pair of videos, he takes us through troubleshooting two engines. Keith goes on to show some of the common failures he’s found while working on these wonderous little machines.

First off is the paint. If you find nuts, bolts and random parts painted in different colors, the engine is probably bad. It sounds strange, but [Keith] has found this to be a rule over his years of working with these engines.

Another problem is rattles. [Keith] found one of these engines rattled terribly. The culprit was the crankshaft. Not only was it the wrong size, but it was built wrong. These engines use built up crankshafts, rather than shafts machined from a single piece of metal. This engine’s crankshaft was threaded into the crank webs rather than pinned. Whoever built it tried to re-engineer the design of the crankshaft, and failed miserably.

You can check [Keith’s] videos out after the break. Want more displacement? We’ve covered the simplest steam engine, and an insanely detailed steampunk battleship, which of course is powered by steam.

Count Your Zombies! A Left4Dead 2 Stat Tracker

March 17, 2017 by 7 Comments

Sure, you’re getting further and further into the game and finishing missions, but the true progress for a zombie shooter is how many zombies you’ve killed, right? [Evan Juras] agreed, so he set off to build a hardware stat tracker for Left4Dead 2!

Left4Dead 2 tracks a bunch of stats and at the end of each level, those stats are updated on your Steam page. [Evan] used a Python script running on a Raspberry Pi to connect to the internet and grab four different stats from your Steam profile. Those stats are displayed on an RGB 16×2 display. To house the project, a case for it was designed and [Evan] had it 3D printed. There are two buttons on the case: one to update the stats and another to cycle through them. If no buttons are pressed then the display cycles through the stats every minute and updates the stats every 24 hours.

The video below shows a summary of the build process and describes the hardware and software used. [Evan] has plans for tracking stats from other games through Steam and his python code is available on Github. Python is becoming the go-to tool for interacting with video game bots and now, stats — see this list of Pokemon Go bots. Also, check out this feature about running MicroPython on an ESP8266 if you wanted to build something similar to this without the Raspberry Pi.
