Beautiful Freeform Headphone Amp

Beautiful Freeform Headphone Amp

I wrote just last week about British electronics hobbyist Rupert Hirst’s method and homemade tools for bending his own aluminum project enclosures. This artfully-soldered PCB-free headphone jack amplifier is his latest project, and it only serves to reaffirm my impression of Rupert as a man with a refined sense of the aesthetics of DIY electronics. To top it off, he knows how to take a photo, too. The copper wire was harvested from cable intended for home wiring. Looks like Rupert intends to cast the whole thing in clear resin as a finishing touch.

Making Music with the Magnetotron

Our own Michael Colombo created an instrument called the Magnetotron as a project for his New Interfaces for Musical Expression class at NYU’s Interactive Telecommunications Program. Inspired by the glass armonica and the Mellotron, this instrument is made out of a large spinning cylinder with audio cassette tape glued to it. Recorded on each strip of audio tape is a different note, which can be played by placing paddles on them.
