Good news - we're open for limited services in Wembley. Ujima House is now actively under refurbishment and we'd love your help in making the space the best it can be.

Please pay attention to the main LHS mailing list or pop into our #london-hack-space IRC channel and say hello.

During this interim period donations and continued membership are greatly appreciated while we transition to our new space.

Status: Some ingredients and tools purchased, awaiting further motivation (see roberthl's box if you'd like to have a go yourself).

Would like to start making open source soft drinks.

The most popular non-alcoholic soft drinks in the space seem to be Coca-Cola, Dr Pepper, and Sprite. There has also been significant interest in making Ginger Beer, but this has not really been in stock at the space a whole lot.
