Help For High-Frequency Hobbyists

Dead-bug circuit building is not a pretty affair, but hey, function over form. We usually make them because we don’t have a copper circuit board available or the duty of making one at home is not worth the efforts and chemical stains.

[Robert Melville and Alaina G. Levine] bring to light a compromise for high-frequency prototypes which uses the typical FR4 blank circuit board, but no etching chemicals. The problem with high-frequency radio is that building a circuit on a breadboard will not work because there is too much added inductance and capacitance from the wiring that will wreak havoc …read more

555 Timer Robots Will Rule The World

A running joke we see in the comments by Hackaday readers whenever a project includes an Arduino or Raspberry Pi that seems like overkill is to proclaim that “I could have done it with a 555 timer!” That’s especially the case if the project amounts to a blinking light or anything which oscillates. Well [Volos Projects] has made a whole robot out of a 555 timer circuit.

Okay, it’s really a dead bug circuit in the shape of a robot but it does have blinking lights. We also like how the base is the battery, though some unevenness under it …read more

Hackaday Links: September 2, 2018

It’s (was, is?) the end of August, and that means the entire dreadlocked population of San Francisco is out in the middle of the Nevada Desert for a week. Yes, it’s Burning Man, and as always we have a host of builds that make you ask, ‘how did they do that, and how did they get that here’.

For the last few years, the greatest logistical feat of art cars is the 747. Yes, it’s the fuselage of a 747, turned into an art car. The top deck is a convertible. The biggest question surrounding this 747 is how do …read more

Electronic ColorChord Turns Color Into Sound

[Dr. Cockroach] has delighted us again with another of his circuits on cardboard. He calls it steampunk inspired, and while we guess we can see what he’s getting at, it’s more like a sweet example of artful dead bug construction. He calls it the ColorChord. Point its photo cells at a color and it’ll play a tone or a combination of tones specific to that color.

Three 555-centric boards use thumbtacks as connection points which he solders to, the same technique he used for his cardboard computer. They provide simple tones for red, green, and blue and a mix for …read more
