DIY Platform 9 ¾ Sign from King’s Cross

When the story of Harry Potter first took the world by storm in 1997, readers were enamored by J.K. Rowling’s magical universe and the enchanting places within. The ordinary house at 4 Privet Drive in Little Whinging, where “the boy who lived” grew up with his horrible Aunt and Uncle (and their son, Dudley). The Leaky Cauldron, the grubby little pub that serves as the gateway to the fantastical shops and stalls of Diagon Alley. And, of course, the world’s most famous non-existent train platform: Platform Nine and Three-Quarters.

The fictional platform is located in a real muggle-inhabited location – King’s Cross station in northern London. Wizards and witches running at the wall between platforms 9 and 10 would instantly be transported to the mythical platform, where they would say farewell to their families and depart on the scarlet train to Hogwarts School of Witchcraft and Wizardry. Celebrating this connection to the world of Harry Potter, the employees at King’s Cross erected a real-life “Platform 9 ¾” sign in the terminal, which has since become a place of pilgrimage for fans the world ’round.

My sister is one of these many Harry Potter devotees, so this past Christmas I decided to build her her own replica of this iconic sign.

DIY Aperture Science “Dihydrogen Monoxide” Water Bottle

Aperture Science (a.k.a Aperture Laboratories) is a fictional scientific research corporation, whose facility is the setting for the 2007 puzzle-platform video game Portal, as well as its 2011 sequel Portal 2. Aperture’s approach to scientific research is a little… strange, to put it mildly. They have a penchant for testing exotic materials, building maniacal robots, and creating wholesome musical interludes. And, apparently, coming up with long-winded names for storage containers.

The Aperture Science Handheld Dihydrogen Monoxide Containment Unit was a stainless steel water bottle created and sold by Valve Corporation and ThinkGeek for the release of Portal 2, circa 2011. The bottle came in both 40 oz black and 22 oz white variations, with decals for Aperture Laboratories and a disclaimer about the deadly nature of H₂O. Unfortunately it looks like they stopped selling these several years ago – the product page from the Valve store has vanished entirely, while the ThinkGeek product page has both bottles listed as “no longer available”.

I’m not so easily deterred, so I spent this past weekend building my own “Aperture Science Dihydrogen Monoxide Containment Unit” using a stainless steel water bottle and some custom made vinyl decals.

Time Circuit Display: LED Standoffs

The time circuit display is a mix of three LED types: alphanumeric displays, seven-segment displays, and standalone 3 mm LEDs. Each one has a different height off of the circuit board and a different distance to the faceplate. I need to offset the components so all of the parts mate with the faceplate correctly, which requires sourcing LED standoffs and designing my own custom ones.
