Here at OpenEnergymonior we are trying to decide how best to engage with interested parties and to promote exciting open-source development. 

With the development of the emonTx we are considering opening an online shop to sell emonTx PCBs / kits. 

We hope that making emonTx PCBs available at a reasonable cost will help people to quickly get an open-source energy monitor up and running, leaving more time free for development.
