This project page provides a guide to adding both USB and a Web based User Interface (UI) to remote control socket set. In the process we will unlock even more capabilities than are available when you use the socket set as they were originally intended. Part 1 (this post) deals with the hardware, Part 2 deals with programming the chip and Web UI . It essentially builds upon this blog by [befinitiv ] Radio controlled sockets are a great way to save power in your home. Devices consuming more power on standby than the sockets do can easily be switched off with a remote.

Through the process we will unlock even more capabilities than are available when you use the socket set as they were originally intended. Part 1 deals with the hardware , Part 2 (this post) deals with programming the chip and Web UI. The main components are: Arduino (or other AVR-MK2 programmer) Web-server (I used a Raspberry pi , but any computer will work if it’s running Apache and PHP) Lego (if you want to make a Raspberry pi case)

If you want to modify an inkjet printer or build your own inkjet plotter for the purposes of direct resist printing onto copper boards to make printed circuit boards, this is your group. In addition, we now explicitly cover inkjet printing of silver or other conductive coatings or metals directly onto substrates such as fabric, mylar, fiberglass boards, and other substances. As an adjunct to the Homebrew_PCBs list, this list is about design, construction, software, modifications, etc. necessary to inkjet print resist directly onto copper. Please post images, examples, software/firmware, etc. to Files and Photos. James Newton has put together sort of a FAQ of the subject by gathering together information from several people's successful inkjet conversions and posted them on his Massmind site . For other methods of making PCBs and software unrelated to direct inkjet printing of PCB resist, see the Homebrew_PCBs group.

The AR.Drone is earth-shattering. It has blown away every drone expert we've talked to. It's not just a toy: it's a phenomenal piece of engineering that manages to solve some very difficult software problems in order to take flight.

With this in mind, Pete Mills wired up his own super-bright brake light assembly using bright red LEDs. Not only are the lights powered by the onboard electrical system, but they can be toggled to either stay solid, or blink depending on the rider’s choice.
mmmonkey Blown SNES fuse repair
Before you take your Super Nintendo to pieces, you should ALWAYS switch it on after you have unplugged it from the wall. You'll notice that the power light flashes for a split second, this is the console discharging, some people say you need to leave the On/Off switch in the On position for quite a while before dismantling it - this is up to you. If you have started soldering in your SNES without discharging it, chances are you won't be able to switch your SNES back on again, it'll be dead! You've probably blown the internal fuse, which is easy to replace.
The BTKeychain
The BTKeychain is just what its unimaginative name suggests: a keychain with a Bluetooth interface. It's a device I created to solve a problem my wife has: she never remembers where she put her keys. In addition to the Bluetooth interface, the keychain also has a buzzer and a small battery. The Bluetooth interface is always discoverable.I finally managed to get access to a decent camera on a day with good weather! The following video is mostly demonstrating the quadrotors stability under the new four-state Kalman filter I have implemented, that estimates both the current pitch/roll and two gyroscope biases.

amelia marzec | re-wired
Re-wired is is a wearable device that translates ambient sound into haptic feedback using bone conduction technology. I first became aware that experiencing sound through bone conduction was possible when I lost hearing in one ear due to a tumor ( acoustic neuroma ). One of the possible ways to "fix" monophonic hearing is to drill a screw into the skull and attach a receiver to it, such that sound waves are converted into vibrations in the skull. Having an open wound just behind a non-functioning ear was not an ideal solution, so I let my body adjust to having one ear.
Converting an Inkjet Printer to Print PCBs
Recently one of my focuses has been to find a way to make the PCB (Printed Circuit Board) creation process easier. I like being able to design something based on what I want in a circuit and just making it myself on the random weekend. While the toner transfer method has been my go to in the past it’s just not nearly as consistent as I would like it to be. The specific pressure of the iron and timing both make it a hit or miss approach. I’m not a fan of hit or miss I like to know something is going to work every time I try to do it.[UPDATE] This project has been built and is in daily use. Some finishing touches remain to be done. Circuit drawing, as-built (now shows fuses) Project circuit notes (These are .pdf files; you'll need Acrobat or another .pdf reader to view them) These are a serious circuit diagram and detailed notes. Plan on much more than a quick look if you're interested in building this or something similar. See this post in this thread for project pics. This thread is a spinoff from a discussion in the Alternator vs. no alternator thread.

The Descriptive Camera works a lot like a regular camera—point it at subject and press the shutter button to capture the scene.Learn to make a glowing electronic piggy bank in this tutorial video using the Programmable 1 Coin Acceptor . Video on YouTube and Vimeo , code on Github . Coin Acceptor – Programmable 1 Coin Type. Your project may be free-as-in-speech, but that doesn’t mean it has to be free-as-in-beer. This handy coin validator/acceptor module is just like the ones you’ve seen in arcades. First, program it with what coin you want it to accept, any coin from 10.8mm to 25.1mm in diameter can be used.
