Blaster Diy: Usb-c Ir

Want to turn your phone, tablet, or laptop into a universal remote? While many modern Android phones have dropped the built-in IR blaster, you can easily build an external one that plugs directly into your USB-C port. No soldering? No problem. Here’s how to build a simple, solder-free USB-C IR blaster for less than a cup of coffee.

Your computer cannot directly pulse at 38 kHz using standard GPIO (software bit-banging is too slow and jittery). Therefore, we need a microcontroller to handle the carrier generation, while the computer simply sends commands over USB. usb-c ir blaster diy

An IR blaster mimics the infrared signals from your original remote. This DIY version uses a USB-to-TTL serial adapter (programmed as a "virtual COM port") to send raw IR codes from an app to a high-power infrared LED. Want to turn your phone, tablet, or laptop

The IR LED has two legs:

Now the fun part. You can send commands from a terminal, Python script, or home automation system. No problem

Take your two IR LEDs. Connect the positive leg (long) of the first LED to the negative leg (short) of the second. Connect the remaining two legs together.
