Ever get bored of the same old project boxes?
The Altoids mint tin or Radio Shack plastic project boxes are commonly used as cases.
There are many other creative and interesting alternatives out there.
For this project, we use gourd left-overs.
Yes, that is right, a gourd.
Throughout history gourds have seen many uses - from canteens to musical instruments.
Today, gourds are used in the craft world to fashion decorative vases and bowls.

For this Instructable, we use the tops of two gourds to make a combination voltmeter and variable DC power source.
The fez hat is a knob that adjusts the voltage.
This build is essentially the same as another Instructable
The circuitry and components are identical.
This build has a couple of differences.
One is the layout of the circuit board, the other is the use of an analog voltmeter vs. a digital meter.
A big thanks goes out these Instructables!

if a gourd is a plant, wouldn't it rot? or is there something special about gourds, like they have special laser powers or something?
wood is a plant too :-P

 Ha. The gourds were dried first, before I bought them.
Plus, I added a coat of clear enamel which should help keep bugs away.
BTW - Archaeologist have found gourd fragments dating back thousands of years. Although I doubt my DC Monkey would last that long. : )
i saw the gourd thing on dirty jobs once
 Really? That is great! : )
I just keep thinking about the old Beatles song...."Everybody's Got Something to Hide Except Me and My Monkey"

Good Job
LOL! Thanks! : )
