Steampunk IMacs With Real Turning Gears

Macs have always been favorites of case modders, with projects ranging from turning a Mac Plus into an aquarium to retrofuturistic machines that look like they came from the set of [Terry Gilliam]’s Brazil. Some of these casemods are of the steampunk variety, an aesthetic that usually means gluing gears to wood. [Valeriy] and [Cyrill] are bucking that trend with a beautiful iMac crafted from wood, brass, and leather (Russian, Google Translate)

The machine in question is a late-model, impossibly thin iMac. Unlike the old all-in-one computers with clunky CRTs, there’s not much space to dig around inside this iMac, and doing so would probably ruin the machine, anyway. Instead of a complete disassembly a wooden frame was constructed around the display, the aluminum base was covered in veneer, and the back of the iMac was covered in leather.

This is a steampunk computer, though, and that means gears. In this case, the gears and steam elements actually do something. The front of the computer is adorned with a decent replica of the drivetrain of a locomotive that spins with the help of an electric motor. There’s a USB port attached to the front, ensconced in a cylindrical enclosure that opens when a switch is flipped.

If a complete reworking of a modern iMac isn’t enough, the build also included the steampunkification of the Apple Bluetooth keyboard. That in itself is an amazing build, but to see the entire thing in action, you’ll have to check out the video below.

Chromatic Clocks With A Steampunk Twist

There’s nothing like a good clock project, and tacking the steampunk modifier on it only makes it better. [José] built a steampunk clock that does it much better than just gluing some gears on an enclosure and calling it a day. This build includes glowing jewels displaying the time in different colors while displaying the a steampunker’s prowess with a pipe cutter.

The body of the clock is a piece of finely lacquered wood, hiding a perfboard construction with a DS3231 real time clock, a DHT22 temperature and humidity sensor, and a light sensor for dimming the WS2812 LEDs according to the ambient light level.

The rest of the clock is a bunch of 12mm copper pipe, elbows, and t couplers. The end of these pipes are capped off with marbles, with the RGB LEDs behind each of the ‘digits’ of the clock. This is a chromatic clock, with the digits 0 through 9 assigned a different color, based on the resistor color code scheme with exceptions for black and brown. Once you’ve figured out how to tell time with this clock, you should have no problem finding that single 56k resistor in your junk box.

You can check out the video of the clock below.

Steampunk Battleship Complete With Steam Engine!

steampunk fortress

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.

Arduino-Powered Steampunk Steam Gauge

steampunkGauge

[Murphy’s_Lawyer] had some empty space on the wall in his kitchen, so he decided to fill it with a whirring Steampunk gizmo: an Arduino-driven steam gauge.

The build began as an old 10″ Ashcroft pressure gauge sourced from eBay, which [Murphy’s_Lawyer] dissected to determine the state of its guts. Finding the gauge’s Bourdon tube intact, he got to work constructing a method of generating motion without the need for actual steam. The solution was to mount a continuous rotation servo between the tube and the case. The servo lacked the strength to flex the tube on its own, so [Murphy’s_Lawyer] fashioned a simple lever out of brass to help it along.

The electronics consist of an Arduino Uno and an accompanying homemade PCB. The code for the Uno generates random motion for twirling the servo, and three LEDs built into the face reflect values generated for speed, pause and run time. The final upgrade came in the form of a new dial face, which provides some updated text as well as a cutout square that lets you see the previously obscured gears in action. Check out the video below, then see another Steampunk overhaul: the Edwardian Laptop.

A Retro, Not Steampunk, Media Center

[toddfx] wanted to put his Raspberry Pi to work and set about creating one of the best stereos we’ve ever seen: It’s called the Audio Infuser 4700, and turns a conglomeration of old disused stereo equipment into a functional piece of art.

[toddfx] used a Raspberry Pi to stream music over WiFi, but also wanted to play some classic vinyl. He took apart an old Yamaha YP-D4 turntable. stripped it to the bone, and created a fantastic oak enclosure around it. To this, he added a seven-band graphic EQ, aux jacks (both in and out), and a tiny 5″ CRT from an old portable TV.

Where this build really gets great is the fabrication. The front panels have all their graphics and lettering engraved via a toner-transfer like method using copper sulphate and salt. [todd] got the idea from this thread and we have to say the results are unbelievable.

Even though this awesome device only used for music, [toddfx] used the tiny color CRT to its fullest. Flick one switch, and it’s an oscilloscope-like display. Flick another switch, and it’s the output of the Raspberry Pi loaded up with a few MAME games including Pacman, Asteroids, and Space Invaders.

[toddfx] put up a build page for his Audio Infuser and an awesome video for his project, available below.

Steampunk Theremin Goggles

wearable-theremin-goggles

Lots of people build custom steampunk goggles, but most don’t implement any interactivity – they’re just an aesthetic accessory. [Sarah] recently decided to built a pair that, besides looking cool, would engage the wearer in creating sound. She accomplished this by integrating an optical theremin into their design.

To keep the build both affordable and wearable she researched simplified theremins, and eventually settled on creating a basic model that uses only a handful of components and two 555 timers. The main body of the goggles was constructed using mostly random mismatched pieces of metal and leather.  Mounted on the outer edge of each lens, there is a photo sensor and a corresponding slider control. Adjusting the slider alters the level of resistance, therein changing the pitch of the sound. The theremin will produce different pitches and octaves depending on how much light the sensors receive. So, the wearer, or a nearby friend, waves their hands around the wearers head to control it.

The speaker and volume knob are cleverly disguised as the two ‘lenses’. Rotating the volume knob lens adjusts an internal potentiometer that’s held in place by a custom laser etched piece of acrylic. To top it all off, she even designed her own PCB using Eagle.

Check out a video demonstration after the break.

A Steampunk Combination Sketchbook

book

[Admiral Aaron Ravensdale], fine craftsman of steampunk wares, just finished up a new project. It’s a sketchbook protected by two layers of security, covered in gilded leather and drenched in the expositions of a [Jules Verne] novel.

The first layer of security for this sketchbook is a combination lock. On the cover are four switches, each with four positions. These are connected to a PICAXE microcontroller which goes to the next stage of the lock once the correct combination is entered.

The book’s security also includes a knock sensor. With a small piezo element hidden under the cover, [Ravensdale] deeds to tap the book with a specific pattern before it opens. The mechanical part is a small hobby servo also mounted to the cover that releases a pair of brass clasps once both locks are opened.

Like all of the [Admiral]’s builds, it’s a fine piece of craftsmanship, equally well suited to take on a holiday with the baron or to the opium dens of Ceylon.

You can check out [Admiral Ravensdale]’s demo of his sketchbook after the break.
