The moment…The moment…

+ Do it yourself

+ Open-source hardware and software

+ Entrepreneurship / Crowdfunding

+ Creativity

+ Cheaper Tiny Computer

+ Easy of Embedded Development


Do it yourselfDo it yourself

Fix yourself use to be the first stimulus for d.i.y.

Learn different things & life-style

End-to-end developer: wood, firmware, hardware, soldering, mechanics and creativity

Not about paying less or cheaper devices

Exciting moment for D.I.Y communities!
