What you'll need:
a clear glass wine bottle
a 5" by 5" piece of hardwood scrap for the base
2 IN4006 diodes
10 0.47 uF film capacitors
10 3.3 Mohm 1/4 watt resistors
10 NE-2B neon lights
16 gauge bare copper wire
power cord with inline switch
woodworking lathe and cutting tools
sandpaper, various grits
drill press and Forsner bits
soldering iron and solder
hot glue gun and glue sticks
Safety note: This device works at US wall voltages and therefore extreme care should be taken once the power has been connected. Note that capacitors will store a charge and should be discharged safely after being powered up.
Step 1: Cut the Wine Bottle
Step 2: Make the Base
Step 3: Build the Electronics
I used slightly different values for the capacitors and resistors, however the product of the capacitance and the resistance are roughly the same as in the original.
I did not use any shrink tubing as I didn't think it added anything to the set up.
It wasn't necessary to cut the bottle for the power cord as the base had built in routing for the power cord.
I used a power cord with an inline switch.
Step 4: Assemble the Bottle
Flip the switch and enjoy your fireflies.
