Yesterday we had a pretty successful HnT session with 4 hacks:

Ričardas told us about building hot air baloons from trash bags and plastic.

Povilas showed a super economical omnidirectional camera he built from a webcam, a mirror from Ebay and a pinch of C code.

Marius brought an Android phone-based telepresence robot he is building so that his mother could interact with her grandson.

Dalius introduced a bioreactor he is building for beta-carotene farming (he was the winner!).
