Class Up your Haunted House with a Disney Mansion Prop

raspiDisneyPortrait

Die-hard Disney fan [Brandon Etto] must have one of the coolest houses in the block around this time of year, especially now that he’s built his own Master Gracey changing portrait. If you’re unfamiliar with the Disney Haunted Mansion attraction, there are a few different versions at theme parks around the world; the Orlando one features a portrait above the fireplace that miraculously ages into skeletal form.

[Brandon's] recreation uses a Raspi loaded with a Video Looper SD image that cycles through a clip of the aging man image. He fabricated a box to hold a 19″ LCD monitor and mounted an inexpensive IKEA frame to the front. The magic is hidden with window film applied to turn the frame’s glass into a two-way mirror: a technique [Brandon] borrowed from this Halloween Instructable.

For a step-by-step tutorial, you’ll want to head over to [Brandon's] writeup on MAKE, but stick around for a quick video demonstration after the break and check out another Haunted Mansion hack: the Singing Heads.

The “Little Drummer Boy” On a Scanner and Drum:

There’s little more information on this hack, however, it’s quite interesting seeing an automated drum and a scanner playing a familiar Christmas tune.  Check out the video of the duet in action!

A Radial Engine Model:

Through the process of experimentation, two “radial engine models” were produced.  The engine model shown above uses a gear-reduced motor to power it.  The other model uses CNC-cut gears and a motor from an air freshener!

Tips and Tricks on Repairing LCD Monitors:

So do you have a broken LCD monitor? Using techniques described in his post, [Neoxity] claims to have been able to repair 50 out of 60 broken monitors using techniques described on his blog.

Flex Cables:

While we’re on the subject of [Neoxity's] page, why not check out his discussion on “flex cables” used for DIY.  Like the humble resistor, they’re not glamorous, but you’d be hard pressed to find an electronics assembly without one.

Illegal Numbers:

Although not a hack in itself, the “illegal number” is a really interesting concept (mentioned by one of our readers in the comments).  Since all data and programs can, at their core, be represented by a series of 1s and 0s, this can also be interpreted as a number.  Thus, some numbers actually represent copyrighted or trade secret data that would be illegal to possess.

CCFL bike wheel lights

We’d never discount the beauty that is the SpokePOV bike wheel kits, but if you want to just turn your bicycle into a blinding blur, [depotdevoid] has the solution for you. He had a CCFL tube left over from an abandoned LCD monitor backlight repair, and decided to see what it would look like as a wheel light. The result turned out fairly well. He had to figure out how to mount the 8 batteries plus step-up board. He says the extra weight isn’t really noticeable and the light output is quite bright. CCFLs can be incredibly fragile, so take care when you do the actual mounting.
