I think you can afford these displays at these prices except for possibly shipping. You could have one big mass order and split shipping.

Thanks to Holly for the tip.

You can also get it as a kit for $35.

You could make an oscilloscope watch!

Or blood pressure monitor like the vital signs you see displayed in the hospital in the emergency room!

What a good idea, Brad.

Hey yeah, you could be walking around doing your everyday tasks, you then see your vital signs moving away from normal so you rush to the hospital!

We could be on to something here

You could interface it with an Xbee module and monitor systems or you could interface it with a Geiger counter. Or we could have LED Boy on a watch.

Just like the old Nintendo game watches back in the 80's!
