Sci-Fi Contest Roundup: Thinking 4th Dimensionally

Notwithstanding [John Titor] and his time travelling ’67 Corvette convertible, the coolest time machine on wheels has to be the DeLorean from Back to the Future. BTTF is apparently a very popular theme for our sci-fi contest, with a lot of great entries.

You mean to tell me  you made a time machine? Out of a Hyundai Accent?

fluxAfter a careful bit of research, it appears the Hyundai Accent (GLS) has both a higher top speed and faster 0-60 time than a DeLorean, and that’s before the installation of time circuits, a flux capacitor, and plutonium reactor. [docbrownjr] and [Jennifer] decided their Accent was the perfect vehicle for a time machine conversion and decided to add a Mr. Fusion  to the mix.

Like the on-screen version, this version of a Mr. Fusion is made from a kitchen appliance. With the original Krups coffee grinder out of production, the team settled on an iced tea machine. There will, however, be copious amounts of dry ice involved,  as will half-empty beer cans and banana peels.

WiFi-enabled Flux Capacitor

ledAfter knocking his head on a toilet, [Beamsjr] came up with a great idea – a networked flux capacitor, able to display the Teamcity build progress.

This build is going all out with custom PCBs – one for the controller board, and three for the shift registered LEDs underneath the acrylic knobbies in the flux capacitor. WiFi is provided by the TI CC3000 module, with the main microcontroller being an ATmega 328p,

Time circuits on

segmentsHonestly, we’d be a bit disappointed if this contest didn’t have a BTTF time circuit build entry. Luckily for us, [atheros] and [bwa] are on top of things with their time circuit clock, complete with an alarm and FM radio receiver (FM isn’t going to work in 1955, guys).

Unlike a few other time circuit builds we’ve seen over the years, the guys are doing this one up right, with 14-segment LEDs for the month display. They’re etching their own boards for this one, and it’s looking like it’ll be a very cool project when it’s complete.

Is GEK a modern-day Mr. Fusion?

[Nanomonkey] spent the weekend building generators that run off of syngas. All Powers Lab produces Gasifier Experimenter Kits to convert raw material to energy. The kits use Gasification to make a “natural gas like” fuel from materials such as wood chips, walnut shells, construction debris or agricultural waste.

So is this the Mr. Fusion that powered the DeLorean? This Honda fitted with a GEK sure makes it look that way. But all joking aside, this looks like a great way to turn waste in heat or electricity. There’s tons of info on the site to dig through. The controllers are open source which would make it easier to interface with the Google PowerMeter when the system is used as a generator.
