Let's put it all together.
Step 1: Supplies and tools
For materials I used:
scrap MDF (Medium-density fiberboard), 1/2" thick
scrap hardboard or HDF (high-density fiberboard), 1/8" thick
--I think I got both of these from an entertainment center that someone threw out on trash day. the MDF was unfinished (no veneer) and the 1/8" hardboard was from the back of the cabinet. Lots of good materials out there on trash day!
2 cheap solar path lights, probably from Menards
spare wire, to extend the LED leads into the "pumpkin" (I used the paired wires from a network cable)
Schmartboard jumpers (I used these so I could replace LEDs easily and troubleshoot solar circuit/battery problems, but you could just solder it all together.
2 spare LEDs from other torn apart path light projects that didn't work out.
Pumpkin carving patterns. I used two from Pumpkin Masters books that I had.
white latex primer
Acrylic paints, for finishing the pumpkin.
Spray paint, flat black, for painting the mounting board.
Double sided tape
3/4" packing tape
Solder & flux as needed
Finishing nails and wood screws, for putting it all together
Tools I used:
Band saw, but you could use a hand saw or jigsaw
Electric drill and bits
Scroll saw, but you could use a jigsaw or coping saw
Rotary tool with very fine spiral bits
