Toddler Computer Remote

[youtube=http://www.youtube.com/watch?v=ACbLjz-c4LE]

[Killerdark] has built a simple remote for his toddler to control videos on a PC. He gutted a USB number pad, built a new enclosure with the necessary buttons clearly labeled, and mapped the buttons in software.  He could have possibly done better with larger color coded buttons, but really, it seems to work well as is. This reminds us of the giant iPod remote from back in 2006. Good job [Killerdark]

UIRemote: Universal Remote Application For IPhone

[youtube=http://www.youtube.com/watch?v=E-SlcjmqeYw]

When several students from the University of Toronto became tired of having multiple remotes lying around, they decided to do something about it. Their solution to this problem came in the form of UIRemote, a universal remote application for the iPhone. The application allows the iPhone to control anything that is normally controlled by an infrared remote, thanks to the use of a custom infrared adapter that plugs into the phone’s headphone port. It’s a technique similar to our iPod remote control from 2004. While the UIRemote application and adapter are still in beta, the students expect to release both things simultaneously sometime within the next two months.

IPhone Controlled Dog Treat Dispenser

[Stephen Myers] has been toying around with some beta ioBridge hardware. He decided to build a remote control dog treat dispenser. ioBridge‘s hardware is built specifically to make web enabling projects easy. The main controller board has four I/O channels that speak to addon modules. It has an ethernet port on the main board and an easy to configure website.

[Stephen] used a servo addon board for his project. The dispenser is built from a scrap CD spindle attached to a servo. He can issue commands from his iPhone, which shows live video of the kennel. He’ll be building several other automation projects based on this system.

How-to: USB Remote Control Receiver

Now that we listen to MP3s, and watch XVIDs or x264s, a computer is the entertainment center in at least one room of most homes. Unless you have a special HTPC, though, you’re probably stuck using the keyboard to pause, change the volume, and fast-forward through annoying Mythbusters recaps. PC remote control receivers range from ancient serial port designs (who has one?) to USB devices not supported by popular software. In this how-to we design a USB infrared receiver that imitates a common protocol supported by software for Windows, Linux, and Mac. We’ve got a full guide to the protocol plus schematics and a parts list.

A Remote Controlled RGB Light Bulb Lamp

RGB just got a lot brighter by using 3x60Watt flood lights instead of an LED. The bulbs are driven via TRIACs and the whole thing uses a remote control to change the levels of the three bulbs. It is also able to store these levels for later recall. The IR receiver was taken from a dead TV set along with its remote control, or a universal remote set to a Phillips TV can be used. The source code and schematic for this project are available.

Rebooting The Magic SysRq Way


[Cory Wright] shares a tip on how to reboot a system with a failed hard drive remotely. The magic SysRq key is a linux kernel feature that lets you perform a number of interesting operations. If you’re working on a remote system where the disk has failed, you won’t have access to the reboot or shutdown commands. You can issue keystrokes to the magic SysRq device in /proc though, so you can send a hard reboot directly to the kernel with no disk access required.

The Wikipedia entry includes a handy tip on how to properly restart a otherwise frozen machine. It should save you from having to fsck the next time around.

Intervalometers And Timelapse Photography


Time lapse photography can seem out of reach for many of us who don’t have fancy cameras(or a hacked cannon point and shoot). We recently covered using a TI-83 as a timer, and now we’ve gathered a collection of DIY intervalometers to help you get clicking.

Up first, for those of you who don’t want to dismantle your camera, here are some mechanical ones that will work on any camera.

[Simplesimon] has done a fantastic job with this integrated system pictured above. He’s added an adjustable solenoid to click the shutter release. By including a second kit board to handle an RF remote, it has remote single shot capabilities too!
