Andrew liked the sound of nostalgia

The best companion to your music collection

Everyone loves valve hi-fi equipment. A fan of mixing the old with the new, Andrew Smith designed a very high performance valve headphone amplifier. Using a unique combination of thermionic and semiconductor technology, the headphone amp runs from a regulated 15V, 1A wall-wart supply for a complete, no-compromise power system. The headphone amp also includes a DC-DC converter providing the required 175V at 15mA for two channels which shuts down gracefully if the output current reaches 38mA, so there'll be no chance of a burn-up while you're burning up the dancefloor at home. So take a step back in time a little while listening to everything from Beethoven to Britney.

Manly speakers

Munny speaker.jpgExploring around the Instructables site, this self-amended gadget caught my eye - Munny Speakers.

The phenomenon of modifiable Munnys ("The Greatest Do It Yourself Toy") has escaped my attention - perhaps the parents among you are already too familiar with these - but the application here is quite obvious.

"Give your speakers some extra personality by making them out of a vinyl doll. Kid Robot makes the easily hackable Munny doll and I've been meaning to cut one up. The combined need for some new speakers created a happy union of doll and speaker," writes fungus amungus.

Build your own Diddley Bow electric slide guitar

diddley bow slide guitar.jpgFancy building your own Diddley Bow electric slide guitar (or "monochord zither" as my ethnomusicologist father would call it)?

Instructables has a cool project for building one of the Southern States guitars. You'll soon be beating out a rhythm on the single string, changing the pitch with a bottle slide...

Wikipedia describes them:
