LockBox Project

Lockbox Constraints

This pqage describes the requiremens for our Locbox project.

Box

Lock

Table Saw

Sawstop

The table saw cuts wood primarily along the length of the wood (rip-cut).

What we made

Today we used the table saw to cut 2x4s into flatter pieces so that we can use them to make our

Table Saw Safety Rules

Do: Wear Safety Glasses

Remove Loose Clothing

Use Either The Rip

Don't:

Put your fingers within 6" of the blade when it is moving.

Cross cut with rip fence.

Stand right in front of the blade.

Operate with gloves on.

Leave it plugged in.

Operate with tripping Hazards in the area.

Don't leave without vacuuming.

13in Wood Planer

The planer

Today we used the planer to flatten our wood pieces.

Planer Safety Rules

Do:

Wear eye protection. wear safety glasses.

Adjust the cutting thickness to within 1/16" of the material thickness prior to cutting.

Unplug when finished.

Attach the vacuum before use.

Wear safety goggles.

Don't:

Put fingers near the opening.

Pass any material but wood through the planer.

Pass wood with nails/screws through the planer.

Miter Saw

It cuts across the length of the wood. This type of cut is called a cross cut!

1.) It can also cut at angles (Used to make frames for example).

Miter Saw Safety Rules

Do:

Wear Safety Glasses.

Firmly secure the material with your hand outside of the hand placement line and up against the fence.

Vacuum after use.

Unplug the saw (In the classroom) after use.

Reduce exposure to blade.

Don't:

Touch or manually move the blade guard.

Cut material that requires your hand to be inside of the hand placement line (material is too short for this application).

Plug in the saw with the cord across the body.

Measure while material is on the saw.

Biscuit Jointer

Cuts "biscuit shaped" holes on your material so that you can assemble your parts to be both:

1.)Perfectly aligned

2.)Sturdy

Once you biscuit , you glue your pparts together creating what is called a "glue up".

Biscuit Jointer Safety Requirements

Do:
Wear safety Goggles.

Make sure it is set for the appropriate size of biscuit.

Make sure you set the height in the middle of the material.

Mark both sides of the material.

Clamp a block in front of material each time.

Don't:

Put your fingers near the blade when it is plugged in.

Assume the blade won't come out of the material.

CNC Machine

VCARVE PRO is used to develop simple designs for cutting/engraving.

Onshape files are used for more complex designs.

Shopbot software actually controls the machine and runs the CAD files.

Computer Numerical Control Machine (CNC) Safety Requirements

Do:

Run the dust collector.

Vacuum after use.

Wear ear protection.

Wear safety glasses.

Secure your material (with screws or clamps).

Design around your screws

Don't:

Leave the CNC while it is running.

Don't go near the gantry while it is running.

Orbital Sander

Use/Function: Smoothes out flaws, and prepares wood for staining (smooths out wood surfaces). It can even resolve edges that didn't perfectly match up! YAY!

Do:

Wear Safety Glasses.

Keep your sander moving at all times.

Be careful not to place sander on skin.

Don't:

Operate the sander without first asking the teacher.

Touch the sand paper while the sander is operational.

Lock Research

Password Arduino Lock

This password Lock is battery powered and uses an arduino as well as a servo. The arduino will be wired to itself or a breadboard from a protective pad under the lock that was applied using what I assume to be a heat resistant/thermal glue/adhesive, The servo will be used to move the Lock and the two will be attached to make that possible using a Lever. Once the pysical components are set up I will need to code the correct code into the arduino. Once that's done it will open only to that code.

Yes because everything needed can be obtained on class.

In the video he uses a metal sliding lock. metal holder and a paper clip. When I do it I could replace those with a 3D printed slider, holder and lever. These changes will allow me to make the constraints that say I need 3 digitally designed components. I will be using TinkerCAD to get a clear visual of what am making. Since I'll be using the 3D printed counterparts instead of the metal items I believe it should help make it ore durable rather than having metal wear down over time with every use.

RFID Arduino Lock

It acts as a Keypad Lock. After wiring up RFID to the breadboard and you need to setup the RFID tags. In order to assure that the RFID tags are setup correctly you should use two LEDS. Along with the held Lock components I will have to drill a lever that can be held by the servo that will be coded to move when the correct tag is over the sensor.

Most of the materials used are obtainable in class except for the RFID tags and the "RFID plate" in which if I decide to go down this route I could buy my own. I don't know if we have any resistors at school but I believe that we do.

Does it meet the constraints for this project and why? The sliding piece of the Lock and the 3D printed holder as well as the lever that will be attached to the servo. It will be designed on TinkerCAD.

To make it reliable and fully functional I will need to make a base for the arduino to sit in. I will be aided in this because I made my box a cube and double on all sides so I have a bit more space to work with.

Wooden Lock

There is a cut wood piece that is on the lock made to accept another input piece that was made to allow you to move it to the side and up to lock it. It's attached with nails.

This is feasible to make in class because we have the ability to woodwork in class. The nails can be

Prototyping Day 1

Today we began prototyping the lock of our choice. I began by breaking down my robot in order to use some of my wires. I grabbed some extra breadboards in order to accurately wire up my lock. I did not finish but I have wired my LEDs, my resistors, my RFID RC522 and my arduino. I also began wiring my servos.

Wood Staining Expectations

Do

Wear gloves.

Always stain over a drop cloth.

Put a small amount of stain on your rag.

Use cotton cloth to apply stain.

Mix stains.

Leaving staining materials out always put them away.

Leave stain rags out (Leave them in your container).

Waste gloves (place them inside out inside of your ziploc bag to reuse for the remainder of the project).

Final Lock Documentation

Actuator

I created this Actuator design on Onshape by using the line and arc tools. I specifically used the center point arc to assure that it was even. I placed circles on the design in order to make holes. I used the dimension tool in order to make sure that it was accurate. This piece was then laser cut out of wood.

Lock Front

I created this Lock front design on Onshape by drawing a rectangle and placing an Arc. This was done by using the line and Arc tools. I added circles of different shapes to my Lock front in order to create holes on my design. I used the measurement tool to add dimensions to my document. This piece was then laser cut out of wood.

Rotor

I created this Rotor design on Onshape by drawing a circle around the center point. I drew lines on the right side of my rotor with a center point arc in order to create the space for the Actuator to complete it's turn. I added a circle to the middle of my design in order to create a hole in my design for the dowel to go through. I also drew lines on the top left side of my design in order to create a space for the "notches" on my Lock. This piece was then laser cut out of wood.

Machine Learning Project

The Goal of My Model?

The Goal of my machine learning model is to detect what the item in an image is and to get it to be as accurate as possible. In my case it needs to accurately depict Bluetooth headphones, Earmuff Headphones, a Mouse and a Battery Pack.

The data collection process

The images on the left are my images collected on the computer that will be used in my code. I spun the object around as well as moved it back and forth in front of the camera. The process created 50 images for each item. The pixels in my images are 48x48.

My Data

To the left you can access my collected Data for my project

Building the model

3 Accurately labeled images

Below I have my model accurately predicting 3 of my items. This was able to do this because I used my item data to train my model to get it as accurate as possible.

3 mislabeled Images

I am not able to provide this section because of how easy and varied the code/pictures were. After training it my predictions were 100% accurate. So, while I'm not able to provide these criteria this is the best outcome for my model.
