[MetroMPG], an environmentally friendly car enthusiast from Ontario, added a tail to his car to increase gas mileage. This 1998 Pontiac Firefly is a sibling of the cheap and popular Geo Metro. He had already done some work to cover a portion of the rear wheel wells to reduce drag. Using cardboard, duct tape, and an aluminum frame he extended the rear of the car by around six feet.
The results are pretty impressive. His extensive testing can be seen in the video after the break and reveals a Miles Per Gallon increase of 15.1% at 90 km/h to get to 64 MPG. The tail is removable but we’re thinking it’s a pain to keep relocating the tail lights from the original body to the removable one.
Now we’re wondering if someone is doing this to our Smurf-blue Metro that we sold to the junk man for $100 back in 2001. It ran great, if you weren’t caught in the cloud of blue smoke coming out the back.

Furries: is there nothing they cannot do? Well okay, “shower” remains an elusive concept, but wearable technology seems to be in, as evidenced by this robotic mood tail. [Wei-Chieh Tseng]’s adorable Arduino-driven fashion accessory operates either via Wii Nunchuk or a set of RFID cards tagged with specific emotions to depict.
Details are scant. It appears to have been a project for a physical computing or design class. One thing’s for certain: Halloween is going to be awesome.
We’re not 100% sure the usefulness of this hack, but it is extremely interesting regardless and will probably make a lot of furries happy. WolfTronix presents their method for creating a realistic animatronic wolf tail. It uses an Atmel MCU controlling two servos alongside a mess of Klixx toys and paper clips to produce a nice wag motion. The guide is extremely detailed and looks to be fun, so long as you don’t mind the monotonous task of shaving off potentially hundreds of ‘nubs’ as they call them. Either way, you’ll definitely have the best (and only…) tail on the block.
