1. Introduction

The Laser1 module provides the basis for a laser bearing finder. This module must be placed on a platform that can swivel in place. This module can detect reflected back laser beam energy at supstantial distances (10+ meters.) Reflective tape makes an excellent laser reflector.

2. Programming

There is no programming yet.

3. Hardware

The hardware consists of a circuit schematic and a printed circuit board.

3.1 Circuit Schematic

The schematic for the Laser1 Module is shown below:

5. Issues

Any fabrication issues are listed here.

• The hole for the laser beam is too small.
• The alignment holes are too small for any reasonable hardware.
• The alignment holes are too close, move further out.
• X1 is too close to N1.
