Video of my espresso scale in progress can be seen here at the 11:12 mark:

Yeah that would be very easy.. I'll add it.

It's such a crazy feeling to be sitting tinkering with a $25 device on a little cutting board and realize you are playing with something that the equivalent of which 60 years ago probably would have cost half a million dollars and been the size of a hotel lobby, and taken a team of people a year to assemble and debug.

I have to agree with you, the ease of just writing a little code and uploading it and communicating back and forth make it a really enjoyable platform; the ease of sending info back to display on the pc console window is another thing that makes it relatively painless to tinker with.

The highlight of my recent project has been getting a nice little options menu system working with a 20x4 lcd screen and a rotary knob, based on a library called LCDMenuLib2.

The ease of use of 3rd party libraries has also been a bright spot in working with the Arduino family.

So far I've only messed with the Arduino UNO and Mega.  The UNO seems quite limited in ram for program code and global variables, but nearly everything just compiles and works fine on the big brother Mega, so it's easy to upgrade when you need to.

Well this is interesting timing.. I've been working for the last couple of weeks on a new Arduino project, a deluxe espresso scale.
I'm having a blast.  I'll put up a youtube video soon.. Here's a quick photo:

First version was on Arduino Uni; here's a slightly newer version running on Mega:
