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 solid 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.
