Good ideas guys, let's keep 'em coming.Does the idea of a shield sound more appealing than having the arduino and the "stuff" all on 1 board?Any interest in a PSTN 56k dial up modem w/voice shield?
A shield that converts all signals to and from 12 volts level so it can be used in a car. 12v dio, 12v adc etc.
* Status shieldHas for every line a LED that shows if it is LOW/HIGH (dimmer if PWM or an analog voltage)e.g. shows (implicitely) SPI I2C communication
I suppose a Tricorder is out?
Here's something I was mocking up a while back. Its essentially an arduino uno clone with the atmega8u2 + atmega328 with standard .100" pitch sockets, so there is no need to have a separate "programmer" like the other tiny boards. It actually measures 0.5" x 1", the copper looking round thing is a US penny. Never built any since it seemed moot, just did it for fun.
