|  Plus42Wire - I2C Bus Interface
Here's another thing to celebrate the new year!
This time it's called Plus42Wire and it's an I2C (Inter-Integrated Circuit, sometimes known as 2-Wire) interface for our beloved machines, with an onboard Real-Time Clock (RTC) and an EEPROM that can easily be read or written from the machine itself.
If you know what I2C is, I think you'll find this board pretty useful as it opens up a lot of possibilities, only the sky's a limit! 
Happy new year everyone!

Isn't 42 wires too much? 
This, like all of your boards, looks so awesome! Even though I can't really add anything useful, I appreciate looking at the pretty pictures

You know, it's never enough!
There's more in store BTW!

Wow, these developments go beyond my imagination and my humble knowledge. I do remember the Philips TVs internal communication was via I2C bus, it was told to be pretty fast and it required very few wires.
I remember a lot of sensors could be connected in this way to the TV mainboard, eg. the light sensors adjusted the brightness of the screen or via I2C controlled the ambilight function too.

Yes, the I2C protocol is used a lot for connecting sensors. You can see this very frequently in the Arduino world. It has the pro of using only two wires, but it is relatively slow, since the address must be transmitted first for every communication and since it is sort of half-duplex.
SPI is a similar protocol that is faster and full-duplex but it requires one more wire per peripheral. Be patient for that...
