We found this Waterwall project on the Sump.org site, and while its an oldie it’s just too funny to pass up. This project is the logical result from combining my wish to keep them out of my room with their natural fear of water. So far they had proven very hard to teach about my […]

Tutorial: Arduino and IR control
Tronixstuff has posted a tutorial explaining how to implement IR remote control in an Arduino project. His demo uses the Vishay TSOP4138 IR receiver and his own downloadable IRremote library for Arduino. This segment is the latest in a series of Arduino tutorials posted by Tronixstuff.
Parallax Propeller/WiiMote white board
In this project, Gareth from Let’s Make Robots demonstrates how to interface a Parallax Propeller with the WiiMote and LCD display to form a white board. Inspired by the work of Johnnie Chung Lee with the WiiMote, Gareth uses the Propeller chip programmed in the Spin language to process data and interface with the display. […]
Arduino, IR remotes and X10
Here is a three-part series by basbrun progressing from analyzing IR protocol to using Arduino’s to control X10 devices via IR: Part 1 -examining the IR protocol (the USB Infrared toy could be used in this step!) Part 2 -controlling LEDs with IR remote. Part 3-controlling X10 devices with IR remote.
Traffic lights and MIRT
Why do traffic lights seem to change green whenever emergency and government vehicles approach? Through the use of various technologies, one of which involves use of a Mobile InfraRed Transmitter (MIRT). An IR sensing device like that pictured above is mounted near overhead traffic lights and senses certain IR LED pulse codes sent by approaching […]
PIC18F2550 USB HID – IR multimedia control board
This PIC18F2550 USB HID device is an IR multimedia control board designed to support Winamp and MS PowerPoint. Via the contact form.
Vehicle data collection and processing system
As you travel this holiday weekend you may notice these IR devices mounted on police vehicles, at turnpike toll plazas and elsewhere along highways. They are designed to automatically read license plate numbers and check them against a database. Here’s an abstract describing how these systems work.
USB infrared decoder
Arthur sent in his USB infrared decoder. It uses a PIC18F2550 to process the IR signal and send it to the PC as keyboard commands. Via the contact form.
IR remote controls webcam movement
In this project, Oh-zap uses a Picaxe 08-M along with a Sony protocol remote to control the movement of a servo with attached webcam. Via Electronics-lab.com
USB IR Toy: Perl scripts for signal analysis
Anton and rct contributed a bunch of Perl scripts for analyzing Infrared Toy output. There are scripts for analyzing raw data in NEC, RC-5, and Panasonic formats. Another script converts IR Toy .bin files .ict files that can be loaded in IRscope (shown above). The USB IR Toy is $20, including worldwide shipping.
Infrared remote control jammer
Our friend Alan at Hacked Gadgets released a new IR Jammer kit that can jam infrared remote control devices.
USB IR Toy: WinLIRC, irPyton updates
WinLIRC, the Windows version of the popular LIRC PC remote control decoder, has seen a spurt of development after 4 years of no activity. The updated version uses a new plugin system that should be able to support the USB IR Toy’s irman decoder mode and rawIO modes. We’re also adding a new mode that […]
DIY USB IR Toy clone
Here’s a DIY, potrable version of the USB IR Toy. It runs the same firmware and bootloader as the IR Toy, but has a few changes: smaller than the original USB IR Toy full integration in a tiny case four IR LEDs for increased range it can be powered with a 9V battery, making it […]
IR remote codes overview
Ken Shirriff’s infrared remote control overview covers different ways to interpret remote control codes, and how to extract codes from various data files available online. This could be good background for anyone adding new remote control protocol support to the USB IR Toy.
IR or RF remote control design
There’s been talk of adapting the USB Infrared Toy to transmit AM radio frequencies as well as infrared light. Today we noticed a similar project by Peter Jakab. Peter’s DIY remote control based on PIC can emit IR or RF, depending on the output device. With an IR LED and it outputs normal remote control […]
IRScope open source remote control visualizer
rct tipped us to the open source IRScope software from the hifi-remote forums. IRScope captures and visualizes infrared signals with the IR Widget, but it could be adapted for the USB IR toy IRIO mode or SUMP logic analyzer mode. You can get a USB IR Toy for $20, including worldwide shipping. Seeed Studio currently has […]
Infrared remote control extender
s3c tipped us to an infrared remote extender at Electronics Lab. A 555 timer IC is set to oscillate at 38kHz. Each IR pulse from a remote control, detected by a TSOP1738 IR receiver module, activates the timer. The timer blinks several IR LEDs through a transistor at 38kHz, recreating the input signal. Handy little […]
