  Step 1

  Probably the hardest part of the whole process is to install the SMD components. Be careful to get the orientation correct. For the next round, I should do a better job on the silkscreen, but the good news is that all of the transistors are oriented the same way. Check the board layout if you need to confirm. I used a film stencil and my toaster oven (with thermal controls) to do the reflow. All the SMD is on the back, so it's pretty easy. Even by hand, it shouldn't be terrible, just slower. The segments are installed on the front.

  Step 2

  When complete mechanically, wire up the SPI and power to an AVR programmer. The Makefile and code is intended for use with avrdude and avr-gcc, but it should be easily adapted for other platforms if desired. I have the JTAG3ICE, but any programmer that can work in PDI/SPI mode should work. The first step is to reprogram the fuses to increase the internal clock speed. If you run:

  make fuse

  it will set the fuses appropriately.

  Step 3

  Finally, you should be able to run:

  make install

  and the code will be compiled and uploaded.
