[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.
Planting your car just about anywhere almost always comes at a price; and, if you’re overdue for your return, odds are good that you’ll end up paying a much steeper price than intended. Parking meters are wonderful devices at telling the authorities just how much time you have left until you’re ticketworthy. [Zack] figured that five–even ten minutes late—is an absurd reason to pay a fine, so he’s developed a tool that will preload a meter with a few extra coins when the authorities get too close.
The law-enforcement detection system puts together of number of tools and techniques that we’re intimately familiar with: 3D printing, Arduino, a photoresistor, and a proximity (PIR) sensor. At the code level, [Zack] filters his analog photo resistor with a rolling average to get a clean signal that triggers both by day and by night. The trigger? Two possibilities. The PIR sensor detects curious law enforcement officers while the filtered photoresistor detects the periodic twirling siren lights. Both events will energize a solenoid to drop a few extra coins through a slide and into the meter slot.
For a collection of well-known components, [Zack] could’ve packed his contraption into a Altoids Tin and called it a day. Not so. As an interaction designer, looks could make or break the experience. For this reason, he opts for a face-hugging design with a steampunk twist. Furthermore, to achieve compatibility across a range of devices, [Zack’s] CAD model is the result of adjusting for various meter profiles from images he snapped in the urban wilderness. The result? A clean, authentic piece of equipment compatible with a family of meters.
For the shrewd-eyed observers, [Zack’s] first video post arrived online in 2011, but his work later resurfaced at a presentation in the 2015 Tangible, Embedded, and Embodied Conference by his former design instructor [Eric Paulos], who was eager to show off [Zack’s] work. For a deeper dive into the upcoming second edition, head on over to [Zack’s] image feed.

Steampunk extraordinaire [Jake von Slatt] has released his latest creation. This time he’s built a Wimshurst machine from mostly 3D printed parts. The Wimshurst machine is an electrostatic generator and was originally invented in the late 1800’s by James Wimshurst. It uses two counter-rotating disks to generate an electrostatic charge which is then stored in two Leyden jars. These jars are also connected to a spark gap. When the voltage raises high enough, the jars can discharge all at once by flashing a spark across the gap.
[Jake’s] machine has a sort of Gothic theme to it. He designed the parts using Autodesk’s 123D Design. They were initially printed in PLA. Skate bearings were used in the center of the disks to ensure a smooth rotation. The axle was made from the fiberglass shaft of a driveway reflector. The vertical supports were attached the base with machine screws.
The Leyden jars were made from sections of clear plastic tube. The caps for the jars were 3D printed and are designed to accept a short length of threaded 1/8″ pipe. Copper wire was used for the interior contacts and are held in place with electrical tape. The metal sectors on each disk were made from pieces of cut aluminum tape.
You may be wondering how this machine works if it’s almost entirely made out of plastic. [Jake] actually painted most of the parts with a carbon paint. This makes them electrically conductive and he can then use the parts to complete electrical circuits. Unfortunately he found this to be rather ineffective. The machine does work, but it only produces sparks up to 1/2″ in length. For comparison, his other machine is capable of 6″ sparks using similar sized Leyden jars.
[Jake] actually tried rebuilding this project using ABS, thinking that the PLA may have been collecting moisture from his breath, but the result is still only 1/2″ sparks. He suspects that the bumpy surface of the plastic parts may be causing the charge to slowly leak away, preventing a nice build up. He’s released all of his designs on Thingiverse in case any other hackers want to give it a whirl.
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.
