Parts List

The circuit board is completely open source under GPL license and is provided on GitHub as Eagle CAD and Gerber files at this repository.

It is also available for order.

Most of the parts you will need are available from Adafruit. Some that are not available at Adafruit are available from a variety of suppliers. At the end of this list will give you a complete parts list from Digi-Key.

First we will need 2 IR LEDs. We prefer to use a combination of wide-angle and narrow angle LEDs. This narrow 20° angle LED is available from Adafruit. A 40° wide-angle area the available from Digi-Key. See the Digi-Key list at the end.

Super-bright 5mm IR LED

PRODUCT ID: 387
Infrared LEDs are used for remote controls (they're the little LED in the part you point at your TV) and 'night-vision' cameras, and these little blue guys are high powered...

You will also need an NPN transistor and 2 PNP transistors. Here Adafruit has a combo pack of five of each or you can buy them separately in packs of 10.

Bipolar Transistor Kit - 5 x PN2222 NPN and 5 x PN2907 PNP

PRODUCT ID: 3599
Transistors are powerful little electronic switches, and we really like these NPN and PNP transistors whenever we need to control medium-power electronics, such as small motors,...

You will need a 1K ohm resistor and optionally you may need two 33 ohm resistors. Adafruit carries the 1K variety but if you need the 33 ohm see the Digi-Key parts list at the end of the page. We will explain later why you may or may not need the 33 ohm resistors.

Through-Hole Resistors - 1.0K ohm 5% 1/4W - Pack of 25

PRODUCT ID: 4294
ΩMG! You're not going to be able to resist these handy resistor packs! Well, axially, they do all of the resisting for you!This is a 25 Pack of...

You will need an infrared receiver such as this TSOP38238 from Adafruit. In the Digi-Key parts list we specify TSOP38438 which has a slightly better automatic gain control circuit however the 38238 from Adafruit will work fine under most every circumstance. You may also need an infrared learner device the TSMP 58000 from Digi-Key. We will explain later why you might need a TSMP58000.

IR (Infrared) Receiver Sensor

PRODUCT ID: 157
IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for any microcontroller.To use, connect pin 3 (all the...
