This wort cooler looks beautiful. No, it’s not for removing warts, it’s part of the brewing process for the nectar of the gods. Even if it wasn’t meant to create alcohol, we would be drawn in by those pretty copper curves.

We’re not surprised at all to see this remote-controlled bowling ball. We’ve seen remote-controlled spheres several times and this just seems like the logical conclusion. We wish there were some build details though. [via neatorama]

When [Anthony Toth] an aircraft enthusiast, decided remodel his garage, he shot for the sky. He has recreated the first class cabin of a Pan Am 747 circa the 1970s. It took him nearly 20 years to scavenge the parts and over $50,000 to pull it all together. [via makezine]

This super cheap simple cable tester caught our eye. There’s nothing complicated here, pretty common sense really. Why didn’t we think of it?

Over the years, Asimo has become a household name. At least in geek households. We’ve seen him go from crazy looking walking microwave prototype, to giant scary space man monster, to the lovable little guy we know now. You can see the full evolution of Asimo in this picture series.

Got an old box camera? Want to use it with modern 35mm film? Here’s a guide to getting it to work. It mainly just involves making a simple mounting bracket.

We like LEDs a lot, but this is getting ridiculous. This dress has 24,000 LEDs. They power it with iPod batteries spread throughout the dress. This cuts down on the bulk and helps distribute the weight.

Coffee cup technology hasn’t changed much in the last bazillion years. We’re pretty sure cave people carved them from stone, and now they’re made from ceramic which really isn’t that different. Some researchers are changing all that, and designing a coffee cup that is supposed to regulate its temperature in a new way. This mug is manufactured with internal convection channels and is made from a material known for its temperature regulation called PCM. Interesting, but it will probably cost much more than a simple insulated thermos. [via neatorama]

Automated coffee bean roaster

We’ve featured several different ways to roast coffee beans over the years. This is the next logical step. [Nightlife31] shows us how to use an Arduino and a popcorn popper to create a fully automated coffee bean roaster.  You’ll have to modify your popcorn machine to be controllable. This means installing your temp sensor and relays. You can see a basic schematic for that in the project page. The rest involves making a fairly simple circuit on an Arduino protoboard attachment. The end result is quite nice. We wouldn’t mind waking up to some freshly roasted coffee beans in the morning. We’ve seen these done with PID controls,  and directly controlled by a computer. There’s even this one that has a much more involved build with a convection oven mounted on top instead of a popcorn popper.

The incredible breakfast machine

A lot of us skip breakfast in the morning, be it because we don’t have time to make something, don’t have the patience, or for some other reason. Yuri Suzuki and Masa Kimura are aiming to make your breakfast a little easier, a little quicker, and a lot more interesting. Their latest project is a Rube Goldberg-like machine that does everything from fry your eggs to brew your coffee. The coolest part about this project is it was built with the help of the public. The two designers put out an open invitation for people to come help in constructing the device at Platform21, a publicly accessible design forum in Amsterdam. Now if someone would tie this into an alarm clock, we could all wake up to the smell of toast and coffee instead of the super loud 140db alarm clock or the confusing (albeit effective) wake up machine.

Teardown of the Barista

August 18, 2009 By 14 Comments

main

iFixit has done a tear down on the symbolic do-it-yourself Espresso machine, the Starbucks Barista. Believe it or not, there is not a single circuit board in the works. There doesn’t seem to be much to the Barista; A few switches, some solenoids, a heater, and one way spring valve among other things. The assembly of the device is very simple. It is noted that in a pinch it may be torn down with a pair of pliers and washer; in place of a flat head screw driver. We have pondered the possibilities of this machine numerous times, while enjoying a cup of cappuccino. Though most conversations end at the bottom of the cup, many survive such as this Silvia PID looped expresso machine. The very name “Mecha turbo crazy coffee roaster” seems to encapsulate the effects of caffeine quite adequately.

Silvia PIC controlled PID looped Espresso Machine

September 8, 2007 By 9 Comments


Last night I rebuilt my ECM Giotto with a new boiler. I’ve seen PID controlled machines before, but today I stumbled across this modded Rancillo Silvia. [Tim] replaced the internal brain with a PIC controller, added a NES control pad for input, a VFD display and a custom laser cut acrylic top. He used the PIC to provide PID control and PWM heater control with the usual solid state relays. I was leaning towards using a PIC for PID control myself, but then I scored my Giotto. (The heat exchanger and larger boiler makes it a bit of a moot point, but I’m still tempted to add PID boiler controls.)
