SenseCam for someone with memory loss.

SenseCam is a digital camera for someone with memory loss. The patient carries it everyday, it captures photos automatically through out the day. When they forget somethings, they can check the images on the computer. I love this simple idea which has a big meaning to those who needed.

Halloween project made with PIR motion sensor.

Halloween is coming, and people are working hard on making somethings scary to "celebrate!". PIR motion sensor is very useful for this purpose, as you will like your scary machine to operate only when someone is passing. Let's check out this "Jan in the Pan" project, you may get the ideas:)

Details of the project is on this website.

PIR motion sensor saves Energy?

I have few projects interfaced PIR motion sensors, it is a real fun. In reality, you will find the PIR motion sensor commonly used in lighting system.For example, the lamp will be on when there are people walking. Planet green listed out some scenarios that motion sensor would help to save energy for you, but also pointed out that there is a case would waste energy. Huh? the argument is that the sensor consumes electricity, if you always remember to turn off the light in your room, then the power consumed by the sensor is not necessary:) But if you are absent-minded, install the sensor!

Gyrowheel - self balancing bicycle for your kids.

When we were young, we use "training wheels" on the back to learn how to ride a bicycle. Nowadays, there is Gyrowheel. It is a wheel that can balance itself with battery powered. Self balancing technology is not new, we have segway, honda ux-3 etc, but it is interesting to see how this piece of technology can be used in new area in our daily life.
