Others Like “Keeping It Private: Blocking RFID Readers from Reading your ID Card” (top 20 results)
Passports, identification cards, bus passes, and even some credit cards contain RFID tags. An RFID (radio-frequency identification) tag allows a card to be read by a computer from a short distance away. While this is very useful in everyday life, would you believe you can make music with it? RFID + sampled music sounds + a little crafting = a fun musical instrument that is limited only by your imagination. In this science project, you will make handbells out of paper cups that play real sounds,…
Have you ever been annoyed by poor Wi-Fi reception for your phone, tablet, or laptop? Do you wish there was something you could do about it? In this project you will learn how to build a parabolic reflector that you can attach to the antenna of a regular wireless router to help boost its signal.
"Alexa, turn on the lights!" Sometimes it is easy to take the technology around us for granted. But have you ever wondered how a smart speaker like an Amazon Echo® knows what you are saying and how it can control lights and appliances in your home? It can seem like magic if you buy a device that just works when you open the box.
In this project, you will learn how it works. You will build your own smart home device to control an appliance with voice commands using an Arduino®. Get…

There are also popular amusement park or carnival games where you try to move a metal loop along a wavy metal wire without letting the two touch. You can build your own version of these games using
a Raspberry Pi.

Self-driving cars use a variety of sensors to evaluate and navigate their environment. Each type of sensor has advantages and disadvantages. In this project you will evaluate two common types of distance sensor (ultrasonic and infrared) and compare their performance in different scenarios.
When you were little, did you ever make "music" in your kitchen by banging kitchen utensils on pots and pans? What if you could actually take those kitchen implements now, and play them with different sound effects? In this project, you can convert basic kitchen utensils into your own electronic drum set using
a Raspberry Pi.
