At Wetherbees Inc. we spend much of our time in that gray area between analog and digital. Our favorite designs tie analog inputs to power outputs through a microcontroller. Throw in a USB or Ethernet port and you pretty much make our day. I don't know about you, but I still keep a bag of 2N2222A transistors in my parts supply. I don't get a chance to use them much anymore, but it's nice to know that they are there if I need them. Send us your design challenge and see what we can do.
