Fiber optic chandelier with wireless controls

May 2, 2012 By Leave a Comment

After seeing a cool fiberoptic chandelier on Ebay for over $1,000, [Apex Logic] figured he could build one himself that would not only be cheaper, but have more features. Some of the features he was after were for it to be wirelessly controlled, have the ability for full RGB control, and of course to have a custom look. He pulled it off quite nicely as you can see in the video below. He has a wireless controller with 3 sliders representing RGB that you can catch a glimpse of in the second video below.

His page with the build details and the code seems to have suffered some ill fate this morning. Here it is, for when it returns.

Using incandescent bulbs to compensate for a slow start cfl

May 2, 2012 By Leave a Comment

[Dick], like most of us, likes some pretty strong light in his workshop. He’s using CFL flood lamps to save a little energy. Unfortunately, he found that they gradually become brighter instead of that instant light he was accustomed to with his previous incandescent bulbs.

Not wanting to wait around for the lights to reach full power, but still wanting to save electricity, he devised a plan . He would install an incandescent bulb along side the others and fade it out slowly as the others became brighter. He acknowledges that he could have just put a 5 minute timer on it, but the transition would be abrupt and unpleasant. Instead, he built a circuit to get the exact result he wanted.

Just so you don’t miss it, the actual build is available to download at a link toward the bottom of the page.

Chicken coop door using threaded rod

May 1, 2012 By Leave a Comment

There’s no rooster to wake them up, and [Steve] and his wife are fine with that. What they’re not fine with is having to get up early anyway in order to let the chickens out of the coop. Like many small-scale egg farmers they sought out an automatic solution for opening the coup in the morning.

[Steve] had seen a bunch of different automatic coup door hacks kicking around the Internet. But all of the ones he could find used a vertical door and pulleys. His setup has a door that opens horizontally and he realized that he needed to build some kind of linear actuator. What he came up with is a system built with hardware store parts. He’s using a plain old piece of threaded rod along with a coupling nut (they’re usually 3/4″ long or so). The nut is held firmly on the door using a conduit mounting bracket, while the threaded rod is turned by an electric screwdriver mounted to the jamb. Two limiting switches are made up of magnetic sensors often used to ring the door entry bell when you enter a store. An Arduino takes care of scheduling and controlling the motor for opening and closing the door. See for yourself in the high-production-value video after the break.

For what it’s worth, we have seen at least one rope and pulley door that slides horizontally.

Automated cat feeder with a view

May 1, 2012 By Leave a Comment

[Robovergne] wrote in to share his fantastic automated cat feeder with us. After researching the common commercial products he could find, he decided to build one that utilized a home made linear actuator to pull a certain amount out of a reservoir. Initially, he attempted to use microwave motors but ultimately found them to be too weak to force the bits of cat food should they get stuck. He was afraid this extra strain would cause motor failure before too long. Ultimately, he replaced the microwave motor with a fairly strong servo that seems to do the job just fine. He’s currently using an Arduino to time it all, but he does mention that he feels it is a waste of the arduino for such a simple task.

As you can see in the videos after the break, his mechanism seems quite solid. There isn’t a lot of play in the movement and the amount of food coming out seems to be fairly controllable.

Interactive table is slightly different than most.

April 29, 2012 By Leave a Comment

[DanNixon] has put together this unique interactive table concept. Usually, when we see the term interactive table, we think of an LED grid. That just happens to be what we see the most of. While this table does, in fact, have an LED grid in the table top, it also has several other features and some very nice construction.

Instead of going the usual boring rectangular route, [DanNixon] decided to build a more visually appealing structure. The build log on that part alone is worth a peek. After that, he has a small LCD screen for displaying headlines and song titles as well as a compact LED matrix for some visualizations.

Great Job [DanNixon]

Controlling the power with bluetooth

April 25, 2012 By Leave a Comment

[Mike] dropped us a tip to show off a system he has built to control some power sockets based on his proximity.  Initially the project started as a parallel port controlled box to switch the mains power.  Then he got the idea of turning this into a little more interactive of an automation tool. He is utilizing the bluetooth from his cell phone as a locator. When the box senses that he’s in the room, the power is on. When he leaves the area, the power is off.  You can see his ruby code on his web site if you wanted to give it a try or offer improvements.
