I love the ATTiny85. If you buy 100 at a time, they are only 72 cents each.
Like the MSP430, they are available in PDIP form so you can use a solderless
breadboard, and they also have the internal oscillator so you don't need a crystal.
Another advantage for small boards is the 8 pin form factor, although that makes
an 8 input A/D converter impossible.
The reason I might suggest the MSP430 for your application, however, is the cost
of getting started. The STK500 you would want to program the ATTiny85 is $82.16
instead of the $4.30 for the equivalent for the MSP430.
The fact that the MSP430 is ultra low power, is a 16 bit processor, and has more
input and output pins is not an issue for your design. But the ATTiny85 might have
a lot more free software examples for you to use, since it has been around longer.

good morning my dear amateur biologists....we have been developing some workshop ideas around the attiny13 and attiny85. call it a 2$ microchip.and i have been specifically working on some simple pcbs for it, also with the aim to be used in diybio labs, add temperature sensors, control relais, light and stuff.see some first info here:luckily the folks over at MIT hitech / lotech also have been working on it, and made a library, so one can programm these little 8pin DIL chips using the arduino 1.0 language and framework:good luck and one or two burning incubators shouldnt be the worst that can happen....best,marcTo view this discussion on the web visit https://groups.google.com/d/msg/diybio/-/-M2OcZ8M5rIJ.--

and low low power too. (I use MSP430s in a sensor network product)John
