Just thought I would share this:

Started out with an old JAW wideband display that I got from my Brother, it works pretty good... But how about a little more data...
http://youtu.be/pJhWr3sL1ks
Using two 8 digit SPI LED displays from DFRobot.com, displaying RPM, AFR, CLT, and MAT... All driven from the MS2 via 3 spare processor pins and a little bit of code tossed in the user code area of the MS2extra source.
Edit:
Oh and yeah, the RPM is random... I don't have a stimulator, so I'm just manipulating the sensor inputs by touching them.

Re: External LED displays
Cool, nice to see I'm not the only one.
Adafruit displays? Kinda pricey, though they are a little more flexible... The ones I have are $15 each from DFRobot.com

They're $10 each except for the blue and white which are $2 and $1 more, respectively. And they use I2C instead of SPI. By the way, the picture makes them look kind of crappy but that's not the case in real life.

Re: External LED displays
Well, $15 for 8 digits, vs $10 for 4 digits, that's $1.87 per digit vs $2.50 per digit!
They aren't SUPER expensive, but if you need a lot of them, it adds up.
Other options would be a nice big transflective SPI LCD, could fit even more info there... Though if it's a graphics display, it would add a bit more software overhead.
