An Especially Tiny And Perfectly Formed FM Bug

It used to be something of an electronic rite of passage, the construction of an FM bug. Many of us will have taken a single RF transistor and a tiny coil of stiff wire, and with the help of a few passive components made an oscillator somewhere in the FM broadcast band. Connect up a microphone and you were a broadcaster, a prankster, and probably set upon a course towards a life in electronics. Back in the day such a bug might have been made from components robbed from a piece of scrap consumer gear such as a TV or …read more

3D Printing A Synthesizer

Voltage controlled oscillators, voltage controlled filters, and CV keyboards ruled the roost. We’ve gone over a lot of voltage controlled synths, but [Tommy] took it to the next level. He designed a small, minimum viable synth based around the VCO in an old 4046 PLL chip

For anyone who remembers [Elliot]’s Logic Noise series here on Hackaday, this type of circuit should be very familiar. The only thing in this synth …read more

It’s a Synthesizer. It’s a Violin. It’s a Modulin

It sounds a little like a Theremin and looks a lot like the contents of your scrap bin. But it’s a unique musical instrument called a modulin, and after a few teasers we finally have some details on how it was built.

Making music with marbles is how we first heard of [Martin] of the Swedish music group Wintergatan. He seems as passionate about making his own instruments as he is about the music itself, and we like that. The last time we saw one of his builds was this concert-ready music box, which he accompanied with an instrument he …read more
