RFID Immobiliser

[andrew_h] has put together this slick anti theft device for his car. The RFID immobiliser is used to keep the car from starting unless you swipe an RFID tag. Depending on how well you hide it, and how well the person stealing the car knows you, they would have no reason to suspect that they have to swipe the tag. Even if someone steals the car while it is already running, they won’t be able to re start the engine if they shut it off. As usual, schematics and PCBs are available.

Apod, An Update

[youtube=http://www.youtube.com/watch?v=GDaNkff5Yyg]

Apod walks!  If you recall, last year we discovered Apod, the creepy lifelike hexapod creation made by [Zenta]. At that point in time, it basically just shifted around nicely but didn’t do much walking. Well, [Zenta] has been hard at work since then and now Apod is fully active, walking, running, and serving drinks with smooth motion. Want to learn more about how his inverse kinematics work? Check out this thread.

Lawnmower Converted To Hoe/scraper

[Torx] wrote this instructable on how to convert a lawnmower to another useful tool.  We’re not sure what language he natively speaks, but we doubt it is english, so you might be better off just looking at the pictures to figure out what he’s doing.  To summarize, he has lowered the mower and reversed/bent the blade to scrape the ground. He has also added thick rubber edges all around to try to keep debris from coming out. You might be wondering why he would need something like this, but the last page sums it up pretty well. We could imagine this possibly getting some use in the garden as well. This one does look pretty dangerous though, so don’t blame us if you cut off a hand or lose an eye to some debris. Then again, a regular lawnmower looks pretty dangerous too.

IEE Clock

The IEE clock looks somewhat un remarkable at first glance. Upon closer inspection though, you’ll find out that there are 12 light bulbs crammed in there for each digit. The bulbs sit behind a curved lens with the numerals on it. When the appropriate one is lit, it projects the number on the front of the clock. While it isn’t new, it is certainly new to us. It is also interesting that you set the time by rotating the little dial on the top right. While it may be easier to set the time that way, it seems that it would be prone to getting nudged on accident.

Midi Piano Instructor

[youtube=http://www.youtube.com/watch?v=i7AfiCQQ4nE]

The MIDI piano instructor is a tool aimed at those who wish to learn to play piano, but don’t want to take lessons. The LED bar mounted above the keys lights up to show you exactly what key to press and when. We’ve seen this available in some electronic keyboards for some time, but this unit would be able to fit any standard sized keyboard.  Check the page for schematics and pictures.

Biosphere Lighting

Sometimes, sitting in a windowless office can drive you crazy. Adding a little bit of life and color can really help. [Gripen40k] did this by building a biosphere. He didn’t have any windows though, so he made an LED light on a PIC based timer. What is interesting is what he did with a thermistor. The Cree LED bulb that he salvaged was going to be submerged in the water, so he had to do some workarounds to keep from over heating the biosphere. Read the project log for more details.

Spinning Ball Of LED Awesomeness

Take a few moments and watch this 3 axis rotating LED light display fire up.  The final effect of being an RGB glowing ball is nice, but we’re fascinated with the structure. There are tons of great detailed pictures of the assembly on the forum thread to feast your eyes on. Just getting power to the LEDs was a feat, he passes their power through 6 slip contacts. Parts were pulled from an old VCR and some old fans.
