This security system called G-spot requires that you touch a special place on the car prior to attempting to start it. This is pretty slick as it could be completely un-obvious and doesn’t require any special fobs or minor surgery. With the right placement, no one would ever notice that you had touched it.

[Jeri] got her hands on some of the DuPont Luxprint EL ink and had some fun conducting experiments. She tried different materials for the base and the display itself. Not only does she just play with materials, she also tears apart a VFD and an LCD to see if she could use them for parts. The LCD turned out to be the most successful. We saw this stuff show up at the Bay Area Maker Faire and we’re excited to see it become more accessible.

Well, maybe the title is not so true. This “Porsche” GT3‘s construction is a bit unorthodox, the chassis looks to be aluminum tubing, with bicycle tires and other man-powered parts for propulsion. The body is entirely plastic and tape, yeah…gold…foil…tape. Hey, when you really really want to turn someones head.
Regardless, the car even comes complete with working lights, horn, doors, trunk, and lexan windows. Sure it will never go 0 to 60 (yet), but the mileage is amazing! Follow an amusing video of it after the rift.

We came across a couple of videos of this toddler android. It sits up, rolls over, and responds to humans around it using visual, audio, and sensor inputs. After the break you will see that the movements are quite like that of a young child. The giveaway is the weight of the robot which is evident when its handlers trying to help it get untangled from that blanket. It seems to respond to individuals around with a smile and a twinkle of its… errr… camera eye. We wonder if it would find delight in knocking down some dominoes.
[Rossum's] latest project just hit and as usual, he doesn’t disappoint. Using an ARM cortex M0 he built a gaming system for less than $3 in parts. The M0 is a bit underpowered for this but at $1 it can’t be beat in price. He worked some video generation voodoo to get the signal he wanted but also mentions that upgrading to a bit more expensive chip like the Cortex M3 would solve this problem. The other part of the gaming system is an analog stick (again for about $1) that is the only input for the system.
Can’t say that you remember hearing about [Rossum] before? Go back and check out his Wikipedia reader, AVR media player, and AVR iPod touch killer.
Painting with light
[Jo0ngle] wanted a fun toy and an easy conversation piece. He painted a square on the back of his door with some glow-in-the-dark paint. Now he can draw on it using a blu-ray laser or a UV flashlight. Either way, the effect is quite pleasing. [Thanks Justin]
Resistor decoder rings
This resistor reference card allows you to spin a wheel and dial in the resistor color code for easy reading. We know, you have the simple act of reading resistor code down cold by now. This is still a fun idea that you might use if you’re ever helping someone get into electronics. [Thanks Osgeld]
Resistor bending template
Speaking of resistors, [Jerome] helped us out by designing a resistor bending template. He’s actually marketing himself at the same time. His bending template is folded from one of his business cards, which he came up with after being inspired by some of the unique business cards we’ve covered in the past.
Fake stained glass using old PCBs
[Agg] floated some old PCBs to his friend [Dan] the mason. [Dan] proceeded to turn out an amazing looking stained glass window unit using the colorful leftovers. The picture above doesn’t do it justice, you have to click through to see the real art.
Monovelo monowheel
[Ernst] asked if we’d heard of the Monovelo monowheel. Well we hadn’t. It’s a human-powered vehicle where you sit inside of one large wheel. We don’t see ourselves building one or riding one, but we enjoyed watching someone else do so. We’d like to catch somebody commuting to work with one of these. Seeing this in the bike lane will brighten up anyone’s day.
[Jerome Demers] sent us his extremely detailed semester project. The two part system consists of PICs connected to XBee modules and accelerometers. By using the device a coach can monitor an athlete and correct their minute mistakes.
Did we mention [Jerome] was very detailed? He also goes into the particulars of designing the circuit, using solder paste and baking, designing and laser cutting a case, and even some fun stories. Well worth the read if you have the time.
[David Hyman] built this device to control a LEGO claw. One one end of things is the part you wear, that measures movement of two fingers and your thumb. On the other end of things is a LEGO claw with three opposing digits. You move, it moves. The claw uses light sensors and a gradient strip for position feedback. There is also an up-down wrist action that uses a touch sensor as the input. This is impressive enough to give the sniper rifle a run for its money.
