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.

Needs merging

I think this is the same machine as Equipment/Booch, not sure how we ended up with 2 pages.


CactusFarm is our low bandwidth sensor network based on the jeelab RF12 modules. Runs on 868Mhz and allows pumping of data into cacti graphs.


RMF12pi "hub" is an RF module with python daemon that converts the serial data from a RMF12pi to a webserver in a format suitable for grabbing with cacti. Information can be found on the github readme.

<graphviz border='frame' format='png' >

digraph rfboard{
  hub [label="RMF12pi hub",shape=box];
  cacti [label="graphs",shape=box];
  node1 [label="node 1",shape=box];
  node2 [label="node 2",shape=box];
  node3 [label="node 3",shape=box];
  node1 -> hub;
  node2 -> hub;
  node3 -> hub;
  hub -> node1;
  hub -> node2;
  hub -> node3;
  hub -> cacti;

} </graphviz>
