via HACKADAY: Radio Amateuring Like It’s 1975

It was a tweet from an online friend in the world of amateur radio, featuring a transmitter design published in Sprat, the journal of the G-QRP club for British enthusiasts of low-power radio. The transmitter was very simple, but seriously flawed: keying the power supply line would cause it to exhibit key clicks and frequency […]

via HACKADAY: Start Tracking Satellites with This Low-Cost Azimuth-Elevation Positioner

Tracking satellites and the ISS is pretty easy. All you really need is an SDR dongle or a handheld transceiver, a simple homebrew antenna, and a clear view of the sky. Point the antenna at the passing satellite and you’re ready to listen, or if you’re a licensed amateur, talk. But the tedious bit is […]

via HACKADAY: Raspberry Pi Learns Slow Morse Code

It wasn’t long ago that you needed to know Morse code to be a ham radio operator. That requirement has gone in most places, but code is still useful and many hams use it, especially hams that like to hack. Now, hams are using the Raspberry Pi to receive highly readable Morse code using very […]

via HACKADAY: Homemade LED Clock Stands Test Of Time

In an era when you might get chastised if your mobile phone is more than two years old, it’s easy to forget that hardware was not always meant to be a temporary commodity. We acknowledge a few standout examples of classic hardware still surviving into the modern era, such as vintage computers, but they’re usually […]

via HACKADAY: Why You Shouldn’t Quite Forget The Moving Coil Multimeter

If you were to ask a random Hackaday reader what their most fundamental piece of electronic test equipment was, it’s likely that they would respond with “multimeter”. If you asked them to produce it, out would come a familiar item, a handheld brick with a 7-segment LCD at the top, a chunky rotary selector switch, […]

via HACKADAY: 3D Printed Hovercraft Takes to the Air

Instructables user [John_Hagy] and some classmates built an RC hovercraft as their final project in the Robotics Education Lab at NC State University. It’s a foam slab with a Hovership H2204X 2300Kv brushless motor inflating a skirt made out of ripstop nylon. Nylon is great here because it has a low friction coefficient and is nonporous to […]

via HACKADAY: Scratch That SDR!

When you think of a software defined radio, what language might you consider reaching for to create the software part of the equation? C? C++, maybe? How about Scratch? “What, Scratch as in the visual programming language aimed at young people?”, we hear you cry incredulously. It’s not exactly the answer you’d expect for an […]

DARPA Software Defined Radio (SDR) Hackfest Selects Teams To Explore Cyber-Physical Intersection Of SDR And Drone Technology

The increased use of wireless and internet-enabled devices – from computers to home appliances – and the data they generate are creating opportunities and challenges for the defense and commercial sectors. To help explore and better understand the complex relationship created by the intersection of physical and cyber technology within the ever more congested electromagnetic […]

via HACKADAY: 3D Printed Dashboard CB Mount is Convoy Ready

Some may be surprised to hear that CB radio is alive and well in the 21st century. From disaster response to operating in areas without reliable communication infrastructure, there are plenty of reasons people are still reaching for their radio and not their smartphone. Unfortunately, modern automotive interior design doesn’t have such an enlightened view. […]

via HACKADAY: Space Technology and Audio Tape to Store Art

[Blaine Murphy] has set out to store an archive of visual art on cassette tape. To do so he encodes images via Slow-Scan Television (SSTV), an analogue technology from the late 50s which encodes images in for radio transmission. If you are thinking ‘space race’ you are spot on, the first images of the far […]

World Maker Faire Visitors Urged to Build, Make, Create, Communicate

Ham radio exhibitors at the 2017 World Maker Faire in New York City over the September 23 – 24 weekend urged visitors to “build, make, create, communicate.” Three Amateur Radio clubs took part in the event, held at the New York Hall of Science in Corona, Queens. World Maker Faire drew upward of 90,000 visitors […]

via HACKADAY: Teaching Electronics With A Breadboard Badge

Over the last year, the production of homebrew electronic badges for conferences has exploded. This is badgelife — the creation of custom hardware, a trial by fire of manufacturing, and a mountain of blinky LEDs rendered in electronic conference badges. It’s the demoscene for hardware, and all the cool kids are getting into it. At […]
