This Temperature and Humidity Sensor Project was built by Dave from Plastibots. The project was made to determine if Dave and his wife needed a new humidifier. Instead of going to Home Depot and purchasing a humidity meter he did what any resourceful geek would do, he built his own meter. This meter is probably more accurate than most store bought devices also thanks to the  Sensirion SHT11 sensor that
My daughter wanted to make a custom shirt, the first thought I had was to use the laser cutter to cut out the pattern and letters that she wanted on a piece of card stock to use as a template. The issue with that was the edges were hard to keep close to the shirt so that the painted edges were crisp. It also took a long time since
Taking pictures of the sun can be hard since it is so bright. This video shows how the reflective material that CDs are made from can work as an effective solar filter. “A CD is a fairly simple piece of plastic, about four one-hundredths (4/100) of an inch (1.2 mm) thick. Most of a CD consists of an injection-molded piece of clear polycarbonate plastic. During manufacturing, this plastic is
 This is a cute Micro Arduino Robot actually has a ton of on-board computing power. It isn’t using much of the programmability that the Arduino affords yet but the sky is the limit. This tiny robot uses a sophisticated distance sensor that is used to avoid obstacles, I can see this little thing being able to map a room or run a maze in the near future. Via:
 With some wood, string, a motor and a few various hardware parts you can build a Home Made Inexpensive Motorized Camera Slider. This will let you get some of the cool shots that you see in the movies and will give your product shots the added touch to make them rise above the rest! Daniel Colvin just built this and documented it so that everyone can make one.
Randy Sarafan, the Technology Editor at Instructables built this programmable car platform by taking an off the shelf RC Car and swapped its brains with an Arduino. This allows the new car to have sensor capabilities and programmability. Randy installed a PING ultrasonic sensor in the front of the vehicle so that it can avoid running into objects but the possibilities are endless now that you can write code
Curious Inventor shows us how to make a small batch of SMD PCBs. The video demonstrates how to use a vacuum pencil to hand place SMD components onto a PCB that has been prepared with squeegeed on solder paste. The board is then reflowed in a toaster oven keeping an eye on the temperature profile of the solder paste and the components.
