Nobody doubts the utility of the Arduino Nano and its many clones, and chances are good you’ve got at least one or two of the tiny dev boards within arm’s …read more Continue reading An Arduino Nano Clone in a DIP-Sized Footprint
We’ve said it before and we’ll say it again: being able to build your own radios is the best thing about being an amateur radio operator. Especially low-power transmitters; there’s …read more Continue reading A Super-Simple Standalone WSPR Beacon
We’ve made no secret over the years here at Hackaday of our admiration for the Minitel. The ubiquitous CRT terminals which made 1980s France the most connected country in the …read more Continue reading Minitel, The 1980s Console Game Platform You Never Had
Flying a glider, or similarly piloting a paraglider or hang glider, can all be pathways into aviation with a lower barrier of entry than powered flight. Sacrificing one’s engine does …read more Continue reading Adding Variometer Functionality to a GPS
[CoreWeaver] creates an alarm clock that includes features one might expect in such a project, including an FM radio, snooze button inputs and a display, but goes beyond the basic …read more Continue reading IO Connected Radio Alarm Clock
[Neumi] over on Hackaday.IO wanted a simple-to-use way to drive stepper motors, which could be quickly deployed in a wide variety of applications yet to be determined. The solution is …read more Continue reading Ethersweep: An Easy-To-Deploy Ethernet Connected Stepper Controller
The hobbyists of the early days of the home computer era worked wonders with the comparatively primitive chips of the day, and what couldn’t be accomplished with a Z80 or …read more Continue reading Retro Serial Terminal Uses Modern Chips to Get CP/M Machine Talking
Back in the day, your choice of calculator said a lot about your chops, and nothing made a stronger statement than the legendary Hewlett-Packard Voyager series of programmable calculators. From …read more Continue reading Calculate Like It’s 1989 With This HP15C Emulator
Even the most punctual among us are content to synchronize their clocks to external time sources like navigation satellite constellations, network time servers, frequency-controlled AC mains, or signals broadcast by …read more Continue reading Accurate Digital Clock Keeps Ticking with FPGA
When synthesizers first hit the scene back in the mid-20th century, many were monophonic instruments, capable of producing just one pitch at a time. This was a major limitation, and over time polyphonic synthesizers began to flood into the scene, …read more
