Step 2Board or Freeform?
You can build this circuit on a small piece of perforated prototyping board. If you elect to go this route, you might also want to use an 8-pin uMax adapter for holding the MAXIM chip. Be forewarned, this adapter is not the same as the more common 8-pin IC socket. Although untested, try this MSOP-8 adapter from Digi-Key #33108CA-ND.
If you're more adventurous, you can build this entire circuit freeform. In other words, solder all of the components together without using a board to hold them. Please note that a soldering iron can and will burn off a leg on the MAX1674 with too much heat.
Either way this project is for the advanced electronics builder. Just go slow and don't burn your fingers.
