If you’re looking for a simple way to make an RF transmitter, check out [Tomasz]’s Morse code transmitter. His design uses nothing more than a microcontroller and a 16MHz crystal to tra… ...

The full tutorial is on Instructables, but to make him react to sound; turn his head and flash his LED eyes in morse code patterns, you won’t need many components.

The transmitter can not only encode and transmit messages entered in a terminal client, it also allows the user to send messages by manually operating the key switch.

How Does Morse Code Work? Samuel Morse is to the telegraph what Thomas Edison is to the light bulb—he didn’t necessarily invent the technology, but he did perfect it.

The whitepaper details the breakthrough technologies behind the MM8108 transmitter, demonstrating how Morse Micro has addressed the efficiency trade-off in high-peak-to-average power ratio (PAPR ...
