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
Exploring 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.
