For folks who appreciate a good dose of nostalgia with their personal hygiene, Kylee Lane’s Apple ADB Mouse Soap will definitely hit the spot. Although, to be perfectly honest, I never really associated the ugly beige color of the older machines with cleanliness, but to each their own.
How do you make a walking biped robot, with only 3 servos? In this episode of The Latest in Hobby Robotics, Frits Lyneborg from letsmakerobots.com shows you his inventive way of doing just that.
The programs used the robot on the video can be downloaded here: letsmakerobots.com/node/29379
Tools needed are just very basics, like saw, drill, ruler etc.
Materials are the 3 servos, some wood (4 paint sticks), hot glue, a couple of screws and some thread locking fluid. The servos are controlled by an AXE230, and batteries are used as balancing weight.
You can use either 3 “normal” batteries, or 4 rechargeable, you just need somewhere between 4.5 and 5.5 volts.
You can adjust the the height of the batteries, and there are several parameters to adjust in the programming code as well, to make your robot walk well.
You can also port the simple code to any other micro controller of your choise, and add sensors, arms and more to your own robot.
If you have never build a robot before, the best place to start is probably here: letsmakerobots.com/start
Using a nanosensor “tattoo” and a modified iPhone, cyclists could closely monitor sodium levels to prevent dehydration, and anemic patients could track their blood oxygen levels.
Ray connected an Arduino to a remote controlled outlet, allowing him to to do basic home automation on the cheap.
This month’s Latest in Arduino episode is out. This episode features the Arduino ethernet, I solder up the mini fume extractor, and we discuss a new book about Arduino robots.
Check out Flickr user Rumtopf’s fancy take on the reverse geocache box. For those who don’t know, a reverse geocache is a box that unlocks itself when the GPS sensor inside senses that it’s in a specific spot on the globe. Rumtopf used a snazzy doorbell button to wake an Arduino, which checks the GPS and displays the distance from that spot on an LCD. He also used a magnetic child safety lock as a backdoor to access the inside of the briefcase in case of malfunction.
Yes, you can cross-stitch your own artwork onto this nifty iPhone 4 case. What got me excited about it was that you could just as easily cross-stitch soft circuits on it with conductive thread. With a little extra effort you could barrow a little power and networking from the handset to give your project that extra kick. Or maybe you’ve always wanted a self-portrait done as a miniature latch hook rug. The possibilities are endless with this DIY case for iPhone 4 available from ThinkGeek.
