Continuous Hand-Tool Leveling Device, Shaun Villa Koide
Electrical Engineering
To produce clean and precise cuts, hand-tools (e.g. knives and saws) must maintain a consistent angle of orientation during the entire cutting process. The Continuous Hand-Tool Leveling Device mounts on the desired hand-tool and the user inputs the desired angle of the cutting plane. The device utilizes a microcontroller unit (MCU) and accelerometer to implement real-time angle measurement. When using a hand-tool, the device uses an LED that indicates that the hand-tool’s angle deviates from the user-set desired angle, which prevents any potential mistakes from occurring due to user error. The device easily mounts on many common cutting tools. Additionally, …

There is no commercial available pre-amplifier that takes 3 individual input signals and synthesizes them for an acoustic guitar. The acoustic pre-amplifier takes three separate small signal inputs and combines or isolates to endure amplification depending with user setting. The user deciphers which signal or signal combination is desired. The device features coil pick-up, microphone pick-up, and piezo disc pick-up for variety of tone quality and control.
