THE CUBE is a 3D jigsaw puzzle, with the added feature that a puzzle piece vibrates for approximately a second when it is placed in the correct place in the puzzle. We accomplished this by building an electrical design such that a circuit delivering power to a vibration motor was completed each time a puzzle piece was correctly placed onto a ba

se. We hope that our project will reach the educational goal of improving the process of learning spatial skills by providing positive feedback and encouragement. Our qualitative results indicated that the vibration feedback did make the puzzle experience more fun: our table was occupied with visitors for the duration of the event, and "THE CUBE" was voted "Most Creative". When completed, THE CUBE looks like the picture to the right: In our final haptics project, we aimed to build a haptic device that targeted a more fundamental skill in life than something learned in a high school. We began considering concepts learned at a younger age than high school to meet this interest and came to the conclusion that we wanted to influence learning of spatial awareness in children. To explore the effects of haptic feedback on the experience of developing spatial awareness in children aged seven through ten, we came up with THE CUBE . Below is a description of our research into previous work as it relates to several aspects of our project- spatial learning, 3D puzzles, and vibrotactile feedback. Each of these sources gave us some sort of insight and/or molded our approach. Summary: This paper describes a set of cubes that, when interlocked, rendered their position and orientation onto a computer monitor. Children with and without Developmental Coordination Disorder (DCD) played challenging visual games with these blocks, and their...
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.....
