This is a simple touch sensor module. You can use it to replace a traditional push button. Using the TTP223-B touch detector IC It measures the capacitance of a metallic pad. It can detect the change in capacitance when a finger is near it. This is the same technology used in the iPhone touch screen. So you can place the metallic pad under a non-metallic surface such as a plastic or glass sheet and it will still work as a button. This may be useful for projects that need to be waterproof. You can also make a secret button by placing it inconspicuously behind a smooth surface. For instance, you could place them under a nonmetallic card table and by casually pressing the right location on a tabletop surface you could mysteriously control your DIY project.

Dorothy – a project for those away from home
Using a LinkIt one with a colour LCD to show how far one is from a home location. The colour changes depending on the distance, and can drop location markers at will to "redefine" home if needed.
The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. The technique uses a timer to break down work into intervals traditionally 25 minutes in length, separated by short breaks.
A child came to see me and asked for a pair of shoes, which could light up in the dark. Unluckily, I didn’t have one pair at hand. However, I had some LED modules and house slippers. And a Logic DC Jack could serve as the main board. Search some materials
The Bus Horn
Many people may be interested in origami, so am I. Sometimes，it is necessary to add some electronic devices to make it perfect. I have tried to make a paper bus recently. And a cool play maker have an idea to make a bus horn with Techbox Tricks.
