## Idea Generation

### What is this project about?

Looking for more support narrowing down your idea? Try using the idea matrix on this page.

I am making a laser measuring tape. The LRuler™ will use two lasers to measure the distance to a wall using angles and trigonometry.

### What do you want to get out of this project?

I want to learn how to use lasers by seeing how far they can accurately go, how much power they use, and anything else that I could learn about them. I also want to learn how you can use math to find distances using angles. A small part of this project uses gears so I will also learn about creating and measuring gears in 3d modeling softwears.

*where did the skills go?** we are taking skills out of the idea generation process, in an attempt to make projects more career-focused. If you want to get leveled-up for a project, share it with the appropriate guide or faculty member for feedback upon completion. *

## Guiding Question

### Turn your idea above into a guiding question.

Check out some resources on how to write a guiding question here.

How accurately can you measure distances using two cheap lasers?

## Exploration

### Use this space to take notes, keep track of your sources, or conversations you have with people about this project.

all I need to do is measure the angles that would make each length using https://www.mathsisfun.com/algebra/images/sin-cos-tan.svg (credit goes to zach for the link)

This diagram is

This shows the 1/4 gearing down system that uses 2 1/2 gear down systems.

I made a program to check the angles I need for each distance, https://repl.it/@Cardy64/Angle-Distance-Script (shout out to Carolyn for the python class she taught)

Designed a flat board design to hold the mechanisms and batteries and stuff like that, I'm going to laser cut it out of acrylic.

Here are some photos of my dad teaching me about how to calculate the angles V V V

## Reflection

### Reflect on this project cycle by answering the questions below.

The act of reflecting allows us to pull out the big takeaways that we'd like to remember from this project to make recalling them easier.

**What are some of the most interesting discoveries you've made working on this project?**

I learned about how to model gears in Fusion360 as well as how they fit together.

I also learned about how to use batteries to power lasers

I used triganometry to find the length and angles the gears should be to find specific distances

### 🌹 What did you enjoy most about this project? 🥀 What didn't go well in this project? 🌱 What will you do differently next time?

I really liked having a final project that I can now show to people

I got the angles wrong for all of the distances so I had to re do all of them

I'll pay a lot more attention to the math i do and I'll plan everything better before I start making it
