Things like this are handy for building stuff that works just how you want it to work. It’s a way of letting out your inner Wallace and Grommit and making crazy inventions to make your life easier / more fun or whatever.
Like my current microcontroller board projects are:
1) First synthesizer for my toddler daughter (current progress here).
2) Replacement wireless thermostat for my central heating system. To have a nicer control method and longer radio range than the current device – possibly even to be controlled by a mobile phone app because that’s the kind of sad nerd I am.
3) Dimming lamp for my daughter’s room – with ‘go to sleep’/’wake up’ dimming that dims over a few minutes, and a way of turning it on that doesn’t immediately go to full. Most of the dimming lamps I found either do stupid things like you touch it, it goes to full, then slowly dims, which is a nightmare for a baby room.
I’d quite like one of these to make a teeny tiny box that lets you use bbc iplayer / other internet streaming services / play video / on the TV.
Oh, and if you stuck this, a USB midi keyboard and a powered set of speakers into a box, you could make an extremely powerful and re-configurable synthesizer for not very much money. Which would be cool.
With the IO board, you can use it to control motors, lights, all manner of things, there must be a zillion things that you could do with that!
