A mashup of selected shorts from "Film Racing," an annual contest in which independent filmmaker teams from 10 cities around the US must each produce a 4-minute digital film in exactly 12 hours. Also, a Teenage Mutant Ninja Turtle squares off with, um, an actual turtle. (Thanks, Charlie Weisman!)

Diesel is receiving much attention as an earth-friendlier fuel -- but for automotive engineering guru and multiple land speed record-holder Gale Banks, it's all about speed. We check out the Banks Sidewinder, known as the world's first roadracing diesel truck. The twin-turbocharged, diesel-powered endurance road-racing pickup can go over 222 mph. Banks is an advisor to the Automotive X Prize, and the guy Jay Leno calls when he wants to double the muscle of an 810-horsepower racecar. (special thanks, Ruth and Coop)

Xeni visits a tissue culturing workshop at Machine Project in Los Angeles. Oron Catts and Ionat Zurr of the bio-art collective SymbioticA in Australia teach us how to extract stem cells from bovine bones, and grow a clump of tasty tissue, some spare ears, or a set of pig wings in a petri dish -- in just 9 short months.

(music: Laura Lopez)

Xeni introduces us to the amazing flying machines of Carl Rankin -- they're made from unusual materials, like drinking straws, tape, thread, even restaurant take-out boxes. The "Jules Verne" looks more like a clipper ship than a radio-controlled model plane. Next, you've seen claymation, but -- dough-mation? "Behold the Wonder," a short film by Ben Rodkin.

Mark's exploration of Mister Jalopy's drive-in movie theater on a bicycle starts out normal enough, but gets pretty trippy when Jalopy opens the lid. Care Bears, orangutans, and Mister Rogers all make cameo appearances. All of this magic took place at a "mini Maker Faire" during Felt Club 2007, an annual exposition of cool crap made by interesting people. When the buzz wears off, we step into the Beijing Accelerator. Rotterdam-based artist Marnix de Nijs created this immersive virtual reality experience in which a seated user rotates at the same speed as the landscape they're viewing. This, too, is trippy. Coop suggests that it be known as "Barf Barf Revolution."

CRAFT Magazine editor Carla Sinclair (who co-founded the original bOING bOING zine) gives us a tour of Felt Club 2007, an annual showcase of cool handmade crafts.

Austrian tech-art-pranksters Monochrom show us how to hack into the human brain using a vintage calculator, duct tape, a USB drive, and some pickled onions (preferably Romanian). Then, Mark shows us how to make a very simple motor -- another fun project from scitoys.com.

Update: here's monochrom's extended dance remix director's uncut version of BRAICIN: Link.

Mark shows us how to make an explosive miniature cannon out of some Binaca and an empty film canister (don't try this at an airport, folks). Then, good foods gone bad -- an excerpt from "Snack Mansion," a claymation film by Lauren Adolfsen. When the pizza makes out with the cookie, and the banana barfs, you know it's a party.

Mark checks out a 15-times-larger-than-life Atari joystick replica by Jason Torchinsky, on display at Felt Club XL. Then, 8-bit help for those suffering from projectile dysfunction disorder.

Roaches are gross. Robots are good. But -- cockroch-controlled robots? Roboticist Garnet Hertz made one, and we visit him and his roachbot today. Then, a short film from Walter Robot (aka: Bill Barminski and Christopher Louie) about a broken hearted 'bot who ends up having a different kind of close encounter.

Mad professor Mark Frauenfelder shows us how to make a Curie Effect Magnetic Heat Engine from common household items. Then, Austrian art-pranksters Monochrom sing a song of love for Stanford law prof and famed copyright reform advocate Lawrence Lessig.

Xeni visits BarCamp LA and trys out the work of wearable computing designer "Robo," known to humans as Ross Bochnek. Next, sneaky use expert and garage inventor Cy Tymony swings by Xeni's house -- Xeni's elderly Sicilian neighbor falls in love with the robot Cy constructed out of trash and knicknacks from the 99 cent store.

(Special thanks to Crystal and Jason "Boogah" Cosper and all the BarCamp organizers!)

Mark visits the garage and workshop of "professional amateur" Mister Jalopy, who builds neat things from materials he scavenges from swap meets and garage sales. Mister Jalopy is a connoisseur of fine machine junque and curiosities, and he takes us on a guided tour of some of his most recent retro-mechanical creations and discoveries.

In today's Boing Boing tv episode, Mark Frauenfelder wanders through Maker Faire in search of interesting robots. First, we meet Babbling Head (an animatronic skull that sings sea shanties), Froggo (a weird slimy kitschy creature 'bot with a squid beak for a mouth), and Seeker Robot (GPS-autonomous RoboMagellan contestant), all creations of Eric Lundquist. Then, we stop by Bleeplabs, and listen to strange sounds emanating from a simple (but cute) analog synthesizer. If you dig today's show, you might also enjoy this previous BBtv episode with cool stuff from Maker Faire '07.

What kind of DIY tech wonders can you find at Maker Faire? Make Magazine editor-in-chief and BBtv co-host Mark Frauenfelder traveled to Austin, TX with camcorder in hand to show us. Mark introduces us to a ticklish dinosaur robot named Pleo (above), and a guy named Craig who makes amazing garage-tech musical instruments. (XJ)

Simpsons director David Silverman plays his flaming tuba for us. He built the propane-fueled "Tubatron" himself with help from pyro expert pals, and he puffs out a few bars of the Simpsons theme song. You can catch him and the flammable sousaphone in action at parades from time to time, and every year at Burning Man. (0:00-2:30)

And finally, a (cough) happy ending for the week: BB co-editor Mark Frauenfelder visited the Los Angeles Zoo and watched a zookeeper massage a grateful Tapir. We should all be as blissed-out as this odd-toed ungulate. (2:47-3:28)

Mark talks to Mister Jalopy, a guy who scavenges the world for discarded treasures, often creating some treasures of his own. He shows us the "museum in a jar" he discovered at an LA garage sale. (@0:09-3:38)

And during a trip to Mister Jalopy's garage of delights, Eric Jon Kurland shows off his homemade 3-D movie camera made from scavenged parts, and gets into a stereoscopic camcorder duel with BBtv producer Nihar Patel. (@3:54-end).

The military industrial complex can be fun! Tanks-A-Lot in England rents tanks for corporate events, and sexy time events, too. And Mark built a robot that violates none of Asimov's laws of robotics.

Coffee aficionado Mark Frauenfelder demonstrates his favorite portable coffee maker, the Aeropress, and makes a delicious cup of methamphetamine-free espresso (Intelligentsia Coffee's "Black Cat" variety, to be precise). While you're enjoying that first cup, watch this mesmerizing gogo dancer, Miss Foxie Moxie.

If you're enjoying BBtv and care to add a review on iTunes, where we're a (very) newly-listed show, we'd be most grateful! iTunes Link.

Xeni talks to philanthropist and Microsoft co-founder Paul G. Allen about The Allen Telescope Array, a $50 million astronomy project 6 years in the making that expands the search for extra-terrestrial life. Allen joins researchers from the SETI Institute and UC Berkeley today in Hat Creek, California, to announce that the first phase of the ATA is complete -- 42 of an eventual 350 radio dishes are now active and collecting scientific data from the universe.

Also in today's episode (starting at 4:44), mad professor Mark Frauenfelder dons his lab coat to demonstrate a peculiar sound instrument he made - a "boing box." Mark shows you how to make one yourself! He found the plans on bizarrelabs.com. Learn more in the next issue of MAKE magazine.

And! BBtv has an insanely cool, all-new intro animation, designed by Syd Garon (did the animated feature "DJ Qbert's Wave Twisters," "Somebody Goofed," and "Jack Chick's Titanic") with art from Adam Koford (did hobos! monkeys! laugh out loud cats!). Can you spot all the iconic BB elements in the subliminally speedy montage? Includes goatse and AACS keys, vulcans and tikis, sad popsicles and 8-bit unicorns, EFF and NSA, and much much more. Sound in that intro clip is by Carlos Bêla of Golden Shower, and logo critters by eBoy.
