Google Bike Hack, Quick And Dirty

January 14, 2010 by Caleb Kraft 10 Comments

Many of the projects we post are so well thought out and engineered, they could hardly be called “hacks”. This one, however, falls neatly into the hack category. [Dave] wanted his very own exercise bike hooked to Google maps. Instead of setting up a control system and writing software to control Google maps, he simply hacked a USB game controller. He wired a magnetic switch directly into the board, where the “up” button is. Then he mounted the switch so that it would be triggered each time he rotated the pedal. Though he only has the forward movement done right now, it would be pretty easy to set up a couple more switches at the base of the handle bar for left and right.

While the experience may not be quite as nice as the more complicated one, aside from head tracking, it isn’t that far off.

Weather Clock

January 11, 2010 by Mike Szczys 46 Comments

[Sean_Carney] build this clock that tells the weather instead of the time. The two hands display the current conditions and the temperature. Forty below zero seems amazingly cold if you’re on the Fahrenheit scale but [Sean’s] from Winnipeg so he’s operating on the Celsius side of things.

Two servos move the hands to match the data scraped off of the Internet. An Arduino does the scraping with the help of an Ethernet shield. This reminds us of the Harry Potter clock that tells a persons location.

Steampunk Nixie Clock

January 11, 2010 by Mike Szczys 14 Comments

This single-digit Nixie clock is a thing of beauty. You might hate Steampunk or you might love it, but you have to respect projects where the design gets equal (or more) consideration compared to the function. The electronics used in the project build upon an existing single Nixie design. Instead of hiding the guts inside the clock the PCB has been laid out to augment the design. We think [Blue Metal] hit it out of the park with this one!

Cold Climate Solar Water Heater

January 11, 2010 by Mike Szczys 30 Comments

Here’s a solar water heater setup that augments your home’s water heater instead of replacing it. The system monitors a solar collector panel on the roof for temperature. If the temperature is warm enough, a photo voltaic cell powered pump circulates cold water through the system. The heated water returns to the top of the home’s water heater. Unlike the warm-climate solar heater we saw earlier, this one can withstand freezing because it uses silicone tubing in the collector.

Meat Smoker From 55gal Drums

December 31, 2009 by Mike Szczys 28 Comments

[Joel] wanted to use his newly acquired welding skills to make something useful. With tasty flesh in mind he put together this meat smoker. What resulted is incredible, but the fact that he then gave it away as a gift is just amazing.

A curved joint between two pipes is known as a ‘fish mouth’. They can be a hassle, as with the pirate wheel project, but [Joel] used his noggin to make things easier. He first modeled two 55 gallon drums in CAD. The intersecting curve was then generated by the software, printed out on paper, and stenciled on the drum to be cut out with a jigsaw.

[Joel’s] writeup is greatly detailed and shares many pictures. He makes every part of this smoker, including the wood handles and the stainless steel grates. The guy really knows how to build stuff, but we should have known that after seeing the Crushtoberfest.

Twitter Based Christmas Ornaments Update

December 31, 2009 by Jakob Griffith 2 Comments

When we introduced you to the Twitter Christmas tree ornaments, sadly we had very little information about the project. Luckily [Rob] made contact and clued us in on the inner workings. It even turns out we were wrong about the usage of Arduinos! We invite you to check out all the juicy inner workings after the break.

Ikea Dioder Hack

December 29, 2009 by Caleb Kraft 12 Comments

[Joseph] wrote in to tell us about his Ikea Dioder hack. The Dioder is a lighting system with a silly name from Ikea. It is basically 4 RGB LED bars that are connected to a controller that will cycle their colors in different manners. They aren’t individually addressable, and at $50 aren’t really that great of a deal for people who could build their own. [Joseph] thought that maybe, if the features could be extended, it could be a decent lighting system. He bought it and began searching. Disappointed by the lack of hacks available, he cracked it open and began brainstorming. Ultimately, he decided to interface it with his computer. He can now control it with software, so making an ambilight clone shouldn’t be too difficult.

He does mention that he thought of making 4 independent drivers so that each light bar could be a different color. We agree that this would be the next logical step, possibly even rewiring for individual access to each LED.
