Here's what I got after drawing some devices in Fritzing:

The digiline flash memory is there just for fun. It's just a 24LCxx I2C flash chip (xx is the memory size).

I got very shocked when I saw this on github.
It's a smartwatch designed by Jeija!!! It has also minetest controller mode :D.

It has that ESP8266 Wi-Fi chip at the core. It's a cheap and powerful chip for Wi-Fi...
The ESP8266 is actually much more powerful. It can render dynamic 3D meshes and decode MP3 files, all while serving a webpage and downloading files.

Smaller details: Jeija knows Sprite_tm (a pretty famous hardware hacker)

EDIT: here's the link on the forum

Must be a horrible conductor with 3.03 Volts across that distance...

Where's the fly back diode of your piston?
Also: You will get problems soon with 24LCxx ICs, as they need >= 2.5V and you've only got 2.3V (0.7V drop over the diode).
Look, I programmed a bug for you. >> Mod Search Engine << - Mods by Krock - DuckDuckGo mod search bang: !mtmod <keyword here>

Too sketchy sketch...

Apart from the protection diode for the solenoid, I have to add a 3.3V regulator after the two diodes and feed it with at least 6V (maybe 5V from USB ports depending on the regulator's drop). I plan to use a switching regulator as linear ones like the 1117 are inefficient (~ 30%) and power plants will be battery-powered.

This way, microcontrollers (Atmel ATTiny25/45/85) and other I2C chips should work.
Now I have to find a cheap 3V LDO switching regulator...

Some guy managed to make one...
