via HACKADAY: Another Reason to Learn Morse Code: Kidnapping

Morse code — that series of dots and dashes — can be useful in the strangest situations. As a kid I remember an original Star Trek episode where an injured [Christopher Pike] could only blink a light once for yes and twice for no. Even as a kid, I remember thinking, “Too bad they didn’t think […]

via HACKADAY: An SSB Transceiver Using Only One Device? Surely not!

There are a multiplicity of transmission modes both new and old at the disposal of a radio amateur, but the leader of the pack is still single-sideband or SSB. An SSB transmitter emits the barest minimum of RF spectrum required to reconstitute an audio signal, only half of the mixer product between the audio and […]

We say that it’s a “pirate” station because, despite being ridiculously easy to do, broadcasting on these frequencies without a license is illegal. […]

via HACKADAY: Build Your Own Antenna for Outdoor Monitoring with LoRa

LoRa and LPWANs (Low Power Wide Area Networks) are all the range (tee-hee!) in wireless these days. LoRa is a sub 1-GHz wireless technology using sophisticated signal processing and modulation techniques to achieve long-range communications. With that simplified introduction, [Omkar Joglekar] designed his own LoRa node used for outdoor sensor monitoring based on the HopeRF RFM95 LoRa […]

via HACKADAY: Chiptunes on a Solar Panel

With its vintage sound, there’s no mistaking the unique 8-bit sound of video games from the 80s and 90s.
