Yahoo and backstage.bbc.co.uk have announced a Uk hackday, to be held in London.

This will be a cool event where stuff will be built. I have signed up and here is a quick braindump of stuff i would like to try and build / see built / talk about:

• viridian widgets

desktop widgets to allow me to keep a track of power usage, paper usage and other data wrangling on the physical impact of my computing on the world.

• mypersonalkyoto

A site to really start collating, shifting and sifting my physical footprint. This links back to ideas I have previoulsy posted on my ‘occasional log‘ namely car data and boutique energy companies.

• streetpower

another idea, to get small groups working together to generate power, aid in recycling and motivating other ideas to reduce the carbon footprint of our lives.

I’ll see if I can bring a Wattson or something similar along and see what power data I can dig up for consumption, and what other API’s to mash (when will Dopplr be open?)
