What is Soft-I/O? It is a little block (the small grey box hidden underneath a reused heat sink in the image on the right) that houses a 25-pin Sub-D connector you can attach breakout boards to. Inside the little block there is the smart stuff: soft-devices that you can configure by drag-and-drop. So if you need 10 (p)reloading counters: Soft-I/O is your buddy. Did you need manifold valve control with a feedback mechanism? Ten of them? Do you need to output PWM? Have you got need for analog or digital input? Data buffering? Output in analog or digital? All these soft-devices are built-in and as long as you don't exceed pin count -you may cluster similar pins of up to 8 devices-, you can install as many as you like (some limitations may apply).

These pages list some of the experiments I have ran with the soft-i/o module connected to my mac.

Here is a list of graphs that were made with JPGraph, from utility data gathered with the Soft-I/O module:

• natural gas
• water
• electricity (not yet)
• solar electricity
• solar heated water
