The Pensieve is a magic device which plays a significant role in the Harry Patter series. It allows one to revisit captured memories - either of their own, or from someone else. Various key plot points are revealed through the pensieve as Harry experiences the memories of several other characters. Through the Harry Potter movies, Dumbledore's pensieve takes on a couple difference appearances, but I wanted to stick close to the book description of an ornate stone basin - this agrees with the film version in "The Goblet of Fire", and is also the style it's portrayed in at Universal's Wizarding World theme park.
I wanted a way to view photos from our past Halloween parties in a large bowl of water. Actually submerging photographs wasn't nearly cool enough, so I decided I'd place an LCD display below the bowl and run a gallery of photos in slide show mode. I tried all kinds of orientations and even considered using mirrors, but using a laptop wouldn't let me achieve the pensieve/cabinet shape i was after. So I decided on using a separate LCD monitor inside the prop and an external laptop to run the slideshow.
Step 1: Materials
Here's a rough list of materials I used to build the Pensieve:
- A 19" LCD monitor (4:3 ratio)
- A laptop to drive the monitor
- A large clear bowl
- An ultrasonic water mister
- A couple 2x4" boards
- approx 4 sq feet of thin plywood
- approx one sheet of 1/2" foam insulation
- liquid nails and some screws
- 3 mirror panels (30" x 8")
- various bits of wood trim
- paint (white and gold)
