Building the $100 night light, Part II

Continuing with the "Building the $100 night light" series, Part II focuses on the parts list...

The parts for this project were sourced from Mouser Electronics.  The original list of parts from the Red Circuits schematic was left mostly in tact, with a few minor changes.  For example, the 1M resistors were scaled down to 100K, in order to switch this from a visibly pulsing light to one that appeared solid (flashes faster than your eye can detect).  I also added a case and some screws needed for the final assembly.

At the time of writing, the parts totalled about $15, with $12 being sunk into the ABS enclosure from Hammond.  The enclosure cost was a bit high, but it was exactly the right size, and looked sturdy enough to survive some rough handling, so I decided not to shop around.

The final list is as follows:
