Here is a collection of my DIY audio endevours. The projects below have been inspired by the hugely talented members of www.diyaudio.com.

I love hearing from people who share my passion (illness?) so be sure to drop me a line and let me know if you liked the site/projects, what projects you're working on yourself, or even just to say hello. ;) - Vikash.
