[Ani Niow] built this steam powered vibrator. It has a milled stainless steel shell with a brass motor structure. The motor is a Tesla turbine made from a stack of Dremel diamond cutoff wheels. This drives an off-center weight to create the vibration. She tested it using a pressure cooker as the steam source. It worked, but became so hot it had to be held using welding gloves. It works just as well with compressed air though. You can see the device at the Femina Potens Art Gallery in San Francisco or later this month at Maker Faire.

UPDATE: [Ani] responds in the comments.
Short and sweet today – I just drove about a third of the way across the US.
[Jake]’s been at it again. This time he re-enclosed a dell 1907FP will brass and brass colored aluminum. Just like his previous work, it’s gorgeous. Check out the close up shot of the adjustment keys.
[Jake von Slatt] has sent along a few of his projects, but his timing never quite coincides with mine. It’s about time I give this guy some coverage. His latest project was a pair telegraph sounders – he uses them to tap out RSS feeds from his linux box. The amateur radio code requirement in the US has been dropped, but this is probably a great way to practice your Morse code. His keyboard build is definitely one of the most original efforts I’ve seen.
In its native form, [Clint]’s K-441 is a caulking gun, able to apply silicones, resins, and liquid rubber from a reservoir with compressed air. It’s accurate, powerful, has a huge capacity, and looks strangely steampunk, even for caulking gun standards. This isn’t any normal caulking gun; this device was made from a staple gun. Oh, it also fires shotgun shells with the help of four rifled barrels.
This device that shoots lead, steel, and glue started off its life as an ordinary staple gun, with the usual 23lb pull you’ll find on these guns. By adding a few plates, hand-winding a spring, and milling a few parts, [Clint Westwood] turned this staple gun into a device that would shoot a single .410 bore shell. A practice round as far as shotguns go, but still a serious amount of punch.

Russians blowing up capacitors! As we all know, electronics only work because of blue smoke. [kreosan] is releasing this blue smoke from a few hundred caps. Fun times, even if they are a large number of inert tube shields in their collection of caps.
[mayhugh1] over on the home model engine machinist forum has built an 18 cylinder radial engine. It’s based on the Hodgson 9-cylinder radial engine that has been around for a while. The crank case is machined from a 5″ diameter rod of aluminum. There’s a Picassa album of the engine being constructed as well.
[Richard] wanted a Minecraft server, but not just any Minecraft server; this one demanded a custom case. A grass block was the inspiration, acrylic the medium, and a quad-core Mini-ITX the guts of the project.
Halloween was last Friday, and as always the tip line filled up with costume builds. [Leif] built a Ghostbusters costume complete with Muon trap, [Jeff] printed out some
steampunk post-apocolyptic goggles, and [Green Gentleman] made a death-a-corn, although we’re struggling to figure out why the last one isn’t called an acorn-‘o-lantern.
[Matthias Wandel], a.k.a. the woodgears.ca dude, is well-known in certain circles for being a wizard of wood. One of the first projects that put him on the map was a pantorouter – a router to cut mortises and tenons. He’s going back to his roots and building a bigger version. This version uses models of routers that are available outside North America, and in the latest video [Matthias] has it dialed in very well.
The Open Source Remote Control was an entry for The Hackaday Prize that didn’t make the final cut. It’s now an indiegogo project, and has some really cool tech we can’t wait to see in mainstream RC transmitters.
Not just another steampunk fashion statement, [Johngineer’s] ChronodeVFD wristwatch is as intricate as it is beautiful. Sure, we’ve seen our share of VFD builds (and if you want a crash course in vacuum fluorescent displays, check out Fran’s video from earlier this year) but we seldom see them as portable timepieces, much less ones this striking.
The ChronodeVFD uses a IVL2-7/5 display tube, which in addition to being small and low-current is also flat rather than rounded, and features a transparent backing. [Johngineer] made a custom board based around an AtMega88 and a Maxim DS3231 RTC (real time clock): the latter he admits is a bit expensive, but no one complains about left-overs that simplify your design.
The VFD runs off a Maxim MAX6920 12-bit shift register and is powered by a single alkaline AA battery. A rechargable NiMH would have been preferable, but the lower nominal voltage meant lower efficiency for his boost converters and less current for the VFD. [Johngineer] won’t get much more than 6-10 hours of life, but ultimately the ChronodeVFD is a costume piece not meant for daily wear. Swing by his blog for a number of high-res photos and further details on how he built the brass tubing “roll cage” enclosure as well as the mounts for the leather strap.
If you ask me, Omaha’s first annual Mini Maker Faire was a rousing success. I think that the Faire’s coordinator, [Eric] of Omaha Maker Group would readily agree.The event was held at the Omaha Children’s Museum, an energetic and colorful backdrop for the 30 makers who were on hand to present their creations.
The representatives of the [Omaha Maker Group] had a total of three booths. One of them displayed the various fantastic things that have come out of their ‘space, which we will cover in an upcoming post. They brought the PiPhone that I told you about in my Kansas City Maker Faire post, and [Foamyguy] found a melodic easter egg hidden in the menu. [OMG] also brought their solar-powered EL wire logo sign, a quadcopter, a giant brushbot, a hexapod, a cigar box guitar, a really fun marble run, a steampunk Barbie, and KITT, their award-winning Power Racing Series car. And yeah, you bet it has a Larson scanner.
At their second booth, Fairegoers were constructing their own regular-size brushbots using 3D-printed chassis. These were specially designed to accommodate the toothbrush heads, pager motors, and CR2032s they brought to share. [Sarah] of [OMG] had her own popular booth and was showing off her costumes, clay creations, and jewelry.
