100 watt LEDs have gotten quite cheap these days, and they’re perfect when you absolutely, positively have to blind everyone around you.

You can even “tap” Morse out on one of the tactile buttons!įinally, we have with Portable (morsing) 100W led flashlight.

A smartphone-sized keyboard and a lilliputian OLED display serve as the user interface, while rotary encoder allows for variable code speed. The tiny ATmega1284 powered computer allows him to encode and decode Morse code. rolled his own Arduino-compatible board for this project. This project grew out of his general purpose Portable tiny IoT device project. took things into the digital age with Stand-alone Tiny Morse code encoder/decoder. If the code is accepted, the PIC unlocks the door, and you’re in! All a user has to do is tap out the right Morse code password on the call button in the lobby. inserted a Microchip PIC12 series microcontroller between the speaker and the unlock button. If you didn’t read article about Hacking the Digital and Social System, check it out! Many apartments have an intercom system where you have to “buzz” someone in, activating a solenoid lock in the door. Next up is with Daddy, I don’t have the key. As knows, when butterflies aren’t available, real programmers drive vim with a Morse key! An Arduino converts Morse code characters tapped at the key into keystrokes over USB. then decided to turn it into a USB Human Interface Device (HID), emulating the keyboard of his computer.
Once the paint and grime were removed, and the original wooden plate restored, the key actually looked pretty good.
It was dusty, greasy, and for some reason had been painted hospital green. found an old key at his favorite thrift store. We start with and Morse key HID + ugly hack. This week’s Hacklet is all about some of the best Morse code projects on Hackaday.io! The company still bears the name of that project: Digi-Key. In fact, a company which started out selling a Morse key has gone on to become one of the largest electronic component distributors in the world. For many years, simple code keys and practice oscillators were the “hello world” of hobby electronics. Hackers, makers and engineers have been working with Morse code throughout history.
Originally developed for telegraph systems, code has been sent over wires, via radio, and even with flashes of light. With over 160 years of history under its belt, Morse code is by far the oldest digital signaling system known to man.
