I believe doing small things can also has some impact, at least make yourself happier.
Halloween is coming (and will go soon)! Let's celebrate it.
Step 1: Step 1: crave a pumpkin
many alligators (for testing/pre set)
1 led light bulb
1 battery box
2 AAA batteries
2 small solar panels
For the small solar panels, you could get it from garden lights or small solar panel websites, such as solar pocket factory ,brown dog gadgets .
Step 2: Step 2: draw the patterns
Since this is my first time craving a pumpkin, I just pick one funny pattern from Google picture.
Then start it!
Step 3: Step 3 : testing before the soldering
Diode could prevent current to flow back from battery box to the solar panel, so I soldered it on the panels.
However, if the battery box has a on/off button, we don't need it.
Step 4: Step 4: stick the solar panel to the sunglass
Wire up the panel with LED light bulb and rechargeable battery.
Test it with solar light / real sun light
Step 5: Step 5: decorate the pumpkin the way you like
To scare your friends, put a (plastic)cockroach in the eyes of Jack, that works!
Try it, very simple but good decoration with green energy.
