Steampunk Radio Looks The Business

Radios are, by and large, not powered by steam. One could make the argument that much of our municipal electricity supply does come via steam turbines, but that might be drawing a long bow. Regardless, steampunk remains a popular and attractive aesthetic, and it’s the one that [Christine] selected for her radio build.

The build cribs from [Christine’s] earlier work on a VFD alarm clock, using similar tubes and driver chips to run the display. FM radio and amplification are courtesy of convenient modules. Tubes are fitted for aesthetic purposes, artfully lit with a smattering of color-changing LEDs. Perhaps the neatest touch is the use of valve handles to control tuning and volume. A stepper motor turns a series of gears, as is mandatory for any true steampunk build, and there’s even an electromagnetic actuator to make the Morse key move. To run it all, a pair of Arduino Megas are charged with handling the I/O needs of all the various systems.

It’s a fancy build that shows how far the rabbit hole you can go when chasing a particular look and feel. It’s a radio that would make a great conversation piece on any hacker’s coffee table.  If that’s not enough, consider going for a whole laptop. Video after the break.

Homebrew Laptop Makes A Statement With A Steampunk Theme

Some may argue, but your choice of computing hardware says exactly zero about you, at least when you buy off the shelf. Your laptop or PC is only one of millions, and the chances of seeing someone with the exact same machine are pretty good. If you want to be different, you really need to build something yourself.

This homebrew steampunk laptop does a great job at standing out from the crowd. [Starhawk]’s build is an homage to the Steampunk genre, in a wooden case with brass bits and bobs adorning. The guts are based on an Intel motherboard, a bit dated but serviceable enough for the job. There’s a touch-capable LCD in the lid, and we absolutely love the look of the keyboard with its retro-style chrome and phenolic keycaps. Exposed USB cables run to and fro, and the braided jackets contribute to the old-timey look. The copier roller as a lid hinge is a nice touch too.

[Starhawk]’s build log is long and detailed, and covers the entire build. We’ve seen interesting builds from him before, like this junk-bin PC build for a friend in need. Looks like this one is for personal use, though, and we can’t blame him.

Hand-Forged Cases Make Nixie Clocks Into Works Of Art

Both “Nixie” and “Steampunk” are getting a bit overused. It’s hard to count the number of clock projects we’ve seen recently that combine the two, and normally we’d be loath to feature yet another variation on that theme without a good reason. This is a good reason.

The single-digit Nixie clocks that [Claes Vahlberg] built are, simply put, works of art. There’s a small version of the clock, featuring a single IN-16 Nixie, and a larger version that uses a Dalibor Farny custom Nixie, a work of art in its own right. Each clock has features like time and date, temperature and barometric pressure, and even days remaining in the current lunar cycle. The cases for the clocks, though, are the real treat. Hand forged from steel, they remind us of steam whistles on top of a boiler.

[Claes] doesn’t have many details on the build process — we’ve been in contact and he says he’s working on documentation — but it doesn’t matter. As if all that weren’t enough, the clocks are controlled by a remote, which has its own IN-16 tube and is motion controlled. The last bit is a nice touch since there are no buttons to distract from the smooth lines of the hammered metal case.

We gush, but we think this one really shines. That’s not to take anything away from previous Nixie-steampunk mashups, like this single-digit clock or this solar power meter. But these clocks are a step beyond.

Electronic ColorChord Turns Color Into Sound

[Dr. Cockroach] has delighted us again with another of his circuits on cardboard. He calls it steampunk inspired, and while we guess we can see what he’s getting at, it’s more like a sweet example of artful dead bug construction. He calls it the ColorChord. Point its photo cells at a color and it’ll play a tone or a combination of tones specific to that color.

Three 555-centric boards use thumbtacks as connection points which he solders to, the same technique he used for his cardboard computer. They provide simple tones for red, green, and blue and a mix for any other color. However, he found that the tones weren’t distinguishable enough for similar colors like a bright sun yellow and a reddish yellow. So he ended up pulsing them using master oscillator, master-slave flip-flop, and sequencer circuits, all done dead bug style.

We’re not sure how practical it is but the various pulsed tones remind us of the B space movies of the 1950s and 60s. And as for the look of it, well it’s just plain fun to look at. Hear and see it for yourself in the video below.

And if you want to see some dead bug circuitry as high art then check out this awesome LED ring, this sculptural nixie clock, and perhaps the most wondrous of all, The Clock.

You’ve Never Seen A Flipping Eyeball Like This One!

Inspired by some impressive work on textile flip-bit displays, and with creative steampunk outfits to create for Christmas, [Richard Sewell] had the idea for a flippable magnetic eye in the manner of a flip-dot display. These devices are bistable mechanical displays in which a magnet is suspended above a coil of wire, and “flipped” in orientation under the influence of a magnetic field from the coil.

In [Richard]’s case the eyeball was provided by a magnetic bead with a suitable paint job, and the coil was a hand-wound affair with some extremely neat lacing to keep it all in place. The coil requires about 200 mA to ensure the eye flips, and the job of driving it is performed by a Digispark ATTiny85 board with an LM293 dual H-bridge driver upon which the two bridges are wired in parallel. The whole is mounted in the centre of a charity shop brooch that has been heat-treated to give a suitable aesthetic.

You can see the eyeball in all its glory in the two videos below the break, and should you be curious you can also read our write-up of the original pieces from [Irene Posch] that inspired it.

Smell That? It’s Time.

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.

Printed PC Speakers Are Way Cooler Than Yours

On the off chance you’re reading these words on an actual desktop computer (rather than a phone, tablet, smart mirror, game console…), stop and look at the speakers you have on either side of your monitor. Are you back now? OK, now look at the PC speakers and amplifier [Chris Slyka] recently built and realize you’ve been bested. Don’t feel bad, he’s got us beat as well.

The speaker and amplifier enclosures were painstakingly printed and assembled over the course of three months, and each piece was designed to be small enough to fit onto the roughly 4 in x 4 in bed of his PrintrBot Play. While his limited print volume made the design considerably trickier, it did force [Chris] to adopt a modular design approach with arguably made assembly (and potential future repairs or improvements) easier.

The amplifier is made up of rectangular “cells” which are connected to each other via 3mm threaded rods. For now the amplifier only has 4 cells, but this could easily be expanded in the future without having to design and print a whole new case. Internally the amplifier is using two TDA8932 digital amplifier modules, and some VU meters scored off of eBay.

Each speaker enclosure is made up of 10 individual printed parts that are then glued and screwed together to make the final shape, which [Chris] mentions was inspired by an audio installation at the Los Angeles County Museum of Art. They house 4″ Visaton FR 10 HM drivers, and are stuffed with insulation.

It’s a bit difficult to nail down the style that [Chris] has gone for here. You see the chunky controls and analog VU meters and want to call it retro, but it’s also a brass cog and sprocket away from being Steampunk. On the other hand, the shape of the speakers combined with the bamboo-filled PLA used to print them almost give it an organic look: as if there’s a tree somewhere that grows these things. That’s actually a kind of terrifying thought, but you get the idea.

If your computer speakers were assembled by mere mortals, never fear. We’ve covered a number of interesting hacks and mods for more run-of-the-mill desktop audio setups which should hold you over until it’s time to harvest the speaker trees.
