Hackit: Cocktail Robotics

November 22, 2007 by 19 Comments


Here is a special edition Hackit in honor of Roboexotica. Ever since making the decision to attend Roboexotica we’ve been speculating on the type of machines we’d like to see at such an event. Here are a handful of ideas:

Iceware via rapid prototyping: As we type this post, [Bre] is in the background attempting to build a RepRap style rapid prototyping machine that will construct shot glasses on demand. We were thinking it would be neat to cut beverage glasses out of blocks of ice using a milling machine, but why stick with normal milling equipment? It’s ice right; you could be doing something stupid like using a butane torch for your working tool. We then began to wonder “Has anyone built an ice based rapid prototyping machine?” You could just deposit water on a frozen surface to create your glassware. A group at the University of Missouri has been investigating “rapid freeze prototyping“. Since they’re using water, they only have to create the frozen shell of the part and then fill in the empty cavity with water to create a solid.

Roboexotica 2007

November 22, 2007 by 5 Comments


Tonight marks the kickoff of Roboexotica in Vienna. It’s the world’s leading festival for cocktail robotics. The event aims to explore the role of cocktail robotics as an index for the increasing integration of technological innovations into human lives. It also explores the explosion of radical hedonism in man-machine interaction.

…or it’s just an excuse for a bunch of smart people to get together, build robots, and drink.

The word ‘robotics’ seems to always imply ‘efficiency’, but that’s definitely a no-no at Roboexotica. Fine tuned manufacturer grade cocktail production is not the goal; personality, charm, character, all of these qualities are important in machinery destined for Roboexotica. You can already see some photos from the event setup on Flickr and we’ll be bringing you more posts on the individual machines as we get more information/drinks.

Real Robots From Movie Designs

November 21, 2007 by 12 Comments


Thanks to Star Wars, Plenty of people have built their own R2 units. Pixar’s next movie has been running trailers for a while, and there’s already a group(free membership required) devoted to building real versions of the SGI robot star: WALL-E. I guess I’ll have to call it reverse-forward engineering. WALL-E has some interesting design ideas – it compacts trash into cubes, but it can also retract its treads into the same compacting area. (Pictured is a WALL-E style waste cube, by [Jawa Lunk]) Thanks to [Shannon] deserves the credit for turning me onto this one.

Asus Eee PC Trace Hunting

November 20, 2007 by 16 Comments


There isn’t anything hacked into it yet, but [tnkgrl] spent some time hunting around her Eee PC for some handy hackable extras. I’d been ignoring them, but now I want one. Oh yes, I do. Hit the writeup for details, but [tnkgrl] identified some semi un-used USB connections, an accessible 5v supply and a spare mini-pcie slot that seems to disable the SSD when it’s in use. The currently unusable mini-pci slot is actually pretty intriguing.

Digital Geiger Counter

November 19, 2007 by 12 Comments


Worried about radiation levels? I’m not, but I still want to build one of these. Mr. Fission here was built by the same guy that’s behind the OpenTracker project. [Scott] based it on the Bargraph Geiger counter built by [Russel E. Cliff]. Both use a standard Geiger tube like the LND712. The tube works with high voltages – easy enough with older electronics, but it’s a slightly tougher challenge with todays low voltage gear. [Scott] used the high voltage power supply from the original project, and built the rest around a good ol’ Motorola HC86 series processor. [Scott]’s idea of using an inverter supply designed for a cold cathode lamp is definitely an interesting one.

Hackit: FRS/GMRS Portable Radios

November 18, 2007 by 98 Comments


FRS and GMRS radios have the performance that we wished walkie talkies had when we were kids. I find them interesting because they aren’t quite as tied down as amateur radio bands. (They’re freaking cheap and you can give them to unlicensed users.) I’ve been surprised by the lack of hacks for these little guys. Garmin married them with a GPS unit to create a sort of hand held APRS device called the Rhino. Since I’ve got a couple of kids, I’m thinking that smacking a GPS into one of these little wrist radios with a modified opentracker (PIC based APRS encoder) would be great for tracking the family on hikes and ski/snowboard trips.

The response to Hackit has been fantastic! Each week I’m going to bring up some hardware. You guys get to pick your brains and suggest new, interesting projects. Look for a round-up and bounty post in the next week or so.

So, got a better idea? Let’s hear it!
