AnalysIR have shared a simple technique for viewing the data from IR transmission on an oscilloscope:

The idea is to use a standard IR Led mounted into a BNC/RCA plug using a spare channel making an Oscilloscope infrared receiver. So we set about ordering the connectors, which arrived in the post today. Another way of looking at this device is as a ‘poor-mans’ IR receiver, but if you have an Oscilloscope to plug it into then maybe you are not so poor after all. The idea is to shine your IR remote control on to the IR Led while pressing a key which results in a small amount of current passing through the IR LED. This in turn creates a voltage differential across the terminals of the Led. For this to work well, you need to have the emitter of the remote control right up against the IR LED of the receiver.

The MAX44006/MAX44008 integrate six sensors in two products: red, green, blue (RGB) sensors; an ambient light (clear) sensor; a temperature sensor; and an ambient infrared sensor with an I²C interface. These highly integrated optical sensors include a temperature sensor to improve reliability and performance.

The devices compute the light information with six parallel data converters allowing simultaneous light measurement in a very short time. The devices consume only 15µA (MAX44006) and 16µA (MAX44008) separately in RGBC + TEMP + IR mode, and also have the ability to operate from 1.8V/3.3V/5.5V supply voltage rails.

Irdroid is a universal infrared remote control for smartphones, tablets and other devices, working with the Google Android operating system.  To control your favourite TV, STB or DVD, you need to download the Irdroid APP for Android and to purchase a Irdroid module.

The Irdroid application is available for download from the Android Market and from Appslib (for android tablets) The biggest benefit of Irdroid is that it is compatible with the LIRC project in which database, there are a lot of supported equipment vendor’s some of the famous are Samsung, Sony, Motorola, LG, Panasonic, Philips and many, many more (see here – > http://lirc.sourceforge.net/remotes/).

Another benefit for the Public is that the Irdroid application is free, open source and the source code can be downloaded from http://www.github.com/irdroid

Today we did a quick test of the TMP006 infrared non-contact temperature sensor with an I2C interface. Point it at something and it measures the temperature. We were expecting a simple breakout board we could test with the Bus Pirate, but got full USB-enabled evaluation kits. To use the Bus Pirate with this board check out Joe’s tutorial. You might get this kit if you leave a comment on yesterday’s giveaway announcement (comments on this post will not be considered).

The evaluation kit has two parts: a USB module that presumably works with many different TI breakout boards, and the TMP006 sensor board. The sensor is only available in a BGA8 package, so a breakout board like this is the only way many people can use the sensor. It’s available from Digi-Key in 1s, so we could sell a simple breakout board if you’re interested.

Circuit Skills – Infrared Light @ MAKE… [via]

Infrared light may be invisible to the human eye, but its usefulness in the world of electronics is easy to see. From simple object sensors to wireless data transmission, IR emitters and detectors can be used in a variety of different ways. And their low cost and wide availability makes them a great choice for enhancing an electronics project.

Power Pic RGB with Infrared remote control is a circuit that generates many colors using a RGB LED and fades between them.

The concept comes from Pic RGB project [1] where the goal was to develop a fading algorithm between different colors, randomly generated.
Being its third evolution, this time the goal is to use a remote control to change the colors, either by choosing a specific color or by selecting an automatic color fading mode, in which the software will keep changing colors over the color spectrum!

One of the earliest methods of wireless transmission used was with infrared light. Using wireless IR links has many advantages with the primary two being low cost and low part count to implement. The simplest of on/off switches using wireless IR would take no more than 10 parts, but this tutorial will be going to send asynchronous serial data over a wireless IR link.

This tutorial will create a wireless infrared transmitter using an IR LED and a wireless IR receiver using a phototransistor. Asynchronous serial will be transmit over this link at 9600 BPS. The PIC 18F452 will be used to transmit and receiver this data.

IgorPlugUDP is an ethernet-enabled infrared receiver. This is an old hack that kmmankad brought up in the forum.

What makes it really cool is that the ethernet is bitbanged using nothing but the bare pins of an ATMEGA168. It is transmit-only, it cannot receive network packets, but that’s enough for a lot of projects. [via]

This is a very basic lesson on how to make a contact-less digital tachometer using infrared light reflection technique. It can measure RPM up to 99960 and the resolution is 60 RPM.
