Taiko Trainer

High level Design Overview/Rationale This idea was inspired by team member Gabriel Soares who is part of Cornell’s Taiko Drum Club (Yamatai). Through his practicing and performing with others, he recognized the opportunity to design a drum trainer that can help students better learn to perform their drumming when following the leader of the group and practicing with others. This device would provide them ...

Coil Winding machine counter with Atmega8 and Reed relay

Connectors Everything has been mounted on a test board, including the headers for: ISP programmer (USBAsp), the 5110 Nokia LCD, the power supply (5V in, fed to the 3.3V regulator), the Reed relay connector, the reset button connector and another 2 pins connector, used to read the polarity of coil winding machine's motor, so we know we either increment or decrement the counter. Connectors There are a few con ...

Bluetooth remote controllable (Lego) cars

How it started It started with the idea to make a technical proof of concept combining the Physical Web and WebBluetooth. The Physical Web is an effort by Google to allow interacting with "things" without fiddling around with installing apps or setting anything up. The basic idea behind that is that the "thing" broadcasts a web URL for the client to interact with it. You can read more about it here: https:/ ...
