I just got my MSP-430 (microcontroller kit with two micros for $4.30) and I' just awestruck by how easy it is to use. I am looking to make a few very low-power circuits here and there for my car. For example, one to lock the doors after 30 seconds when I press a button. What do you guys like to use for actually physically constructing the circuit? - Breadboards are easy and require no soldering, but are larger and more expensive. - Stripboards are kind of weird and can't be re-used a lot - Wire wrapping appears to be expensive due to the cost of the tools Secondary question: what is the cheapest battery setup to get 5V? It seems all the normal battery sizes give multiples of 1.5V. Any I am missing?
