What is open source hardware?

S. Bourdeauducq (Milkymist project) Milkymist One August 2011 2 / 1

Openly licensed development kits from chip makers?

In fact nothing really new...

They sell (proprietary) chips.

They always have been happy to see you copy their “referencedesigns”.

Community-developed devices for hobbyists?

Grassroots movement

More potential for open innovation

But...

Niche markets

Small volumes

Hackers are cheap

Low price implies low technology

A video synthesizer for...

VJs who want low latency, cutting edge interactive effects.

Clubs and concert venues who can use it like a nice “lightingeffect”.

Small music bands who want plug and play VJing.

(Hackers who want to play with advanced digital technology.)

Those are niche markets and “small” volumes too, but...

Milkymist One is better and cheaper than existing devices.

which sold in the order of 40000 unitspublicity is of utmost importance (We sold 40 so far)

Competitive even in small volumes.

We can afford cutting edge technology.

Milkymist One is one of the first commercially available embeddeddevices with open source CPU

Milkymist One in more detail

Milkymist One is a product containing a FPGA as centralcomponent.

The FPGA implements the Milkymist System-on-Chip (SoC)comprised of a CPU, I/O interfaces and accelerators.

The Flickernoise video synthesis software runs on the SoC.
