There are a lot of people currently working on this, investing time for the greater good and all of it would be dead in the water without the HW.
Chris31 put it in the public domain and nrgizerbunny is providing a service that is in demand, i myself like many others didn't have the ability to create the hardware and would not right now be facilitating further software dev if i didn't have the hw.
Nrgizer has devised his own pcb and psu and cost of the components considered he's not exactly raking it in.
Its narrow minded posts like this that castrate dev and cripple project enthusiasm.
Its not like Chris31 is being under cut, he doesn't provide a pcb service, what would you have nrgizer do? pay all contributors because he is covering his costs?
This is hardly mass production and with the limited availability of modules never will be.
When the software that i'm assisting production of is complete it will be free and chris31 can have it too, no charge.....who's paying me and the coder and for that matter the people who helped devise the psu components??
The answer is it, this is not profiteering this is enthusiasm, soon to be stifled it seems.
