DIY
The BubbleBoard is an Open Hardware design, which means we are happy give you the circuit diagrams and parts-lists to enable you to build it yourself.
You will need:
Time: not weeks but months and years
Money: more than you might expect
Access to sophisticated production equipment
The ability to manipulate Gerber files
The patience to order 100's of different components (some of them will invariably be 'on allocation' or newer-spec)
The skill to debug multilayer-layer PCBs, and to devise automated test-programs
The sang-froid to embark on a project of this scale
The nous to identify partners who will support the project from beginning to end
The experience necessary to manage a project of this complexity
The commitment to see it through
The sense of humour to throw it all away when it doesn't work [expletive deleted]
In short, it is neither easy, cheap nor quick to build; you'd be ill-advised to contemplate this for quantities below 1,000.
