How 5G is Likely to Put Weather Forecasting at Risk

If the great Samuel Clemens were alive today, he might modify the famous meteorological quip often attributed to him to read, “Everyone complains about weather forecasts, but I can’t for the life of me see why!” In his day, weather forecasting was as much guesswork as anything else, reading the …read more

Ask Hackaday: Experiences With Capacitor Failure

Regular readers of Hackaday are intimately knowledgeable about old electronics, and whether it’s about that old oscilloscope sitting in the pile of other oscilloscopes, or the very rare vintage computer made in a Soviet bloc country, someone somewhere knows how to fix it. One of the biggest problems with these …read more

Televox: The Past’s Robot of the Future

When I read old books, I like to look for predictions of the future. Since we are living in that future, it is fun to see how they did. Case in point: I have a copy of “The New Wonder Book of Knowledge”, an anthology from 1941. This was the …read more

Israel’s Moon Lander Crashed, and That’s OK

Some bittersweet news today as we get word that Israel’s Beresheet spacecraft unfortunately crashed shortly before touchdown on the Moon. According to telemetry received from the spacecraft right up until the final moments, the main engine failed to start during a critical braking burn which would have slowed the craft …read more

The $50 Ham: Checking Out the Local Repeater Scene

So far in this series, we’ve covered the absolute basics of getting on the air as a radio amateur – getting licensed, and getting a transceiver. Both have been very low-cost exercises, at least in terms of wallet impact. Passing the test is only a matter of spending the time …read more

By Jenny List | April 20, 2019

Solar garden lights are just another part of the great trash pile of our age, electronics so cheap as to be disposable.

Some of us are able to get by in life with somewhere between 0 and 1 USB ports. We typically refer to these people as “Mac users”. For the rest of us, too much is never enough, and we find ourselves seeking out expansion cards and hubs and all manner …read more
“Vintage” Radio Gets a Modern Makeover

By Tom Nardi | April 20, 2019

Taking an old piece of gear and cramming it full of modern hardware is a very popular project. In fact, it’s one of the most common things we see here at Hackaday, especially in the Raspberry Pi era. The appeal is obvious: somebody has already done the hard work of …read more
A Breadboard Power Supply That’s More Universal Than Most

By Brian Benchoff | April 20, 2019

A favorite project of ours is the humble breadboard power supply. Yes, you can still prototype on breadboards, no, you don’t need an entire bench power supply to prototype on one, and every breadboard made in the last forty years has had the same pattern of holes. There’s plenty of …read more
Cast Aluminium Becomes A Machine Tool

Shaper tools were, at one time, a necessary tool for any machine shop. With a shaper and a lathe, you can rebuild or manufacture almost anything. At the very least, you can make the tool to manufacture anything. For the last few months, [Makercise] has been working on building his …read more
3D Printed Tank Track Pops Together with Plastic BB for Hinge

By Donald Papp | April 20, 2019

3D printing is well-suited to cranking out tank tread designs, because the numerous and identical segments required are a great fit for 3D printing’s strengths. The only hitch is the need for fasteners between each of those segments, but [AlwynxJones] has a clever solution that uses plentiful hard plastic spheres …read more

The Korg DW-6000 is an entry-level synthesiser from the mid 1980s that has the classic sounds, but not enough of them. At least that was [Mateusz Kolanski]’s view, as he hacked his model with a 16-fold increase in its wavetable memory.

At the heart of the DW-6000 is …read more
