Habit-acquisition system. Tag physical objects like dumbells, medicine bottles, etc with RF tags or microcontrollers, and use them to detect and log users` interactions with these objects. Virtual plants and creatures that simulate the health of real things, like work, schedules, or relationships (as measured by online communication). Best if a cl

ear interface for tracking many different things. A game played on a digital surface where the physical location and orientation of game pieces upon the board causes different game behaviors, events, and outcomes. Multiuser NFC laptop lock screen which tracks recent users of the computer, retaining traces of their presence and usage of the computer. (Useful for making computer applications more discoverable, if people can see what software is used at a certain workstation. ) Virtual spatial interface across multiple computer screens: ability to throw virtual objects from one screen or computer to another in physical space using gestures. Object oriented programming language which is embodied by physical lego-styleblocks. Each block corresponds to an object with a series of functions. Plugging blocks together in different ways creates complete programs. We will create a variety of sensors to be attached to everyday objects like medicine boxes and exercise equipment, which detect when they are disturbed and update a habit-tracking application on your phone or computer. We thought of many physical computing ideas, and chose the one that enabled the most interesting interaction cycle between the user and computer. Dale and Collin were interested in using NFC tags to remind themselves when they forgot to bring things with them. Raymond noticed he left things untouched that he wanted to use, like vitamins, whey, and dumbbells. We...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
