There are three things you'll need to read before you get started. First, the DISCLAIMER: Second, before you start to work with spring wire, read the section on safety . When you have read that section, read it again. No kidding . And third, about this document: I've tried to write for the benefit of someone who has (or can gain access to) basic hand and power tools.
Download HPGL Some notes about gear design and this gear template generator This template generator is intended for generating paper templates for cutting low precision gears from plywood, phenolic, or other suitable materials with a band saw. This gear template generator generates shapes for involute spur gears. Involute spur gears have involute shaped teeth.
Hardware The essential components of the hardware system are Protoboard and MCU Push Buttons Gyroscope Voltage divider XY-Accelerometer Voltage regulator Z-Accelerometer Helicopter Motors - Optoisolator Circuits “Launch Pad” and IO Tether Power Supply The Atmel Mega32 microcontroller is mounted on the provided custom made protoboard. We added three ports, for interfacing with the motors and sensors.
In the past I've used the third hands/helping hands available at chain electronics shops and have been frustrated with their usability. I could never get the clips exactly where I wanted them or it took more time than it really should to get setup right. I also wanted the ability to hold small circuit boards and alligator clips just don't do a very good job. I was familiar with the adjustable coolant hose systems used to spray coolant at cutting tools in the machining industry and thought that would be a great place to start. I ordered various nozzles and hose segments from my favorite online machine tool supply company and started experimenting.
