#### Safety Reminders: - Make sure you can locate PPE, fire extinguishers, and first aid kits. - No open-toed shoes, flip-flops, sandals, or heels. - Tie back long hair, secure loose clothing or jewelry. - In case of emergency, call 911 on your cell phone. - Report any broken or damaged equipment to lab staff. ### Agenda: 3:15: Assignment/Website Review and continued introductions <br> 3:40: <a href='https://learn.sparkfun.com/tutorials/how-to-power-a-project'>Power</a>, <a href='https://learn.sparkfun.com/tutorials/motors-and-selecting-the-right-one/dc-brush-motors---the-classic'>motors</a> / <a href='https://www.makerspaces.com/how-to-solder/'>Soldering</a>. Safety reminders: <br> <ul> <li>Wear eye protection. </li> <li>Use fume extractors.</li> <li>Don't touch hot stuff. </li> <li>Lead waste goes in lead waste tubs. </li> <li>Wash hands after soldering.</li> </ul> 4:45: Break <br> 5:00: Tools, Processes, and Materials - <b>Saw Station:</b> Use a [hand saw](https://www.youtube.com/watch?v=F5YmVHB3P5I), use the [scroll saw](https://www.youtube.com/watch?v=5_fenDdm4oQ). Use [hand files](https://www.youtube.com/watch?v=h4KaiG7CpSQ) and the [bench grinder](https://www.youtube.com/watch?v=OvW4MVvk69A). - <b>Drill Station:</b> Use a [hand drill](https://www.youtube.com/watch?v=d6qzo3LYTR4), use the [drill press](https://www.youtube.com/watch?v=Nu9tYcld7ck), and [tap a hole](https://www.youtube.com/watch?v=CWCQ-hlQvdY). - <b>Assembly Station:</b> - Measure something using micrometer, calipers, protractor, and level. - Joining: [nuts & bolts](https://youtu.be/zIGz8STM-fI), [screws](https://youtu.be/5cA9bZRHpZE), nails, and glue. - Experiment with gears, bearings, belts, pulleys. <h3> Labs:</h3> Split into teams and work on building automata. <a href='../../lab/tools/automata_kit.html' target="_self">Instructions Here</a><br> - Compete to be the fastest team to assemble each of the mechanical components - Try connecting a motor to the mechanisms - Try combining motion primitives into more complex motions (this may also help you conceptualize your kinetic sculpture assignment) - Use Fusion to model a motor mount and coupling, <a href='../../lab/cutting/PS70MotorMountandCouplingTutorial.pdf'>PDF to follow along</a> If there's time left, work on kinetic sculpture assignment. <h3> Readings:</h3> <p> <a href='../../lab/tools/mechanisms.html'>Mechanism design</a>, <a href='https://docs.google.com/presentation/d/1ZqWlTu3C6ChjgVlh-ZcghNG3y8bAC1Wpp0kyp3fGtFE/edit?usp=sharing'>Principles of mechanical design</a>, chapters 4 and 8 of <a href='http://mars1980.github.io/resources/making_things_move.pdf'> Making Things Move</a>. <br> <a href='https://learn.sparkfun.com/tutorials/how-to-power-a-project'>Power</a>, <a href='https://learn.sparkfun.com/tutorials/motors-and-selecting-the-right-one/dc-brush-motors---the-classic'>motors</a>, <a href='https://www.makerspaces.com/how-to-solder/'>soldering</a>. <br> Review <a href='https://learn.sparkfun.com/tutorials/voltage-current-resistance-and-ohms-law'> Ohm's Law</a> and <a href='https://learn.sparkfun.com/tutorials/analog-vs-digital'>Analog vs. Digital</a> inputs <br></p> <h3>Assignment: </h3> <p> <ul> <li>Create a kinetic sculpture. Include circuitry (e.g., a motor and a power source) to move your sculpture. Prioritize making rigid mechancial attachments to the motor body and motor shaft. </li> <li>Solder pins onto your microcontroller </li> <li> Document your work. Use the photo booth in the lab to record a video of your sculpture and <a href='../../lab/website/video.html' target="_self">include at least one video/gif</a> in your documentation. </li> </ul> </p> <p> Some good precedents include [Caleb's goalkeeper](https://calebcapoccia.github.io/ps70/03_fabrication/index.html), [Eliza's sloth](https://elizaknapp.github.io/ps70-portfolio/03_fabrication/index.html), [Victor's shrimp fried rice](https://vleeharvard.github.io/PS70/03_fabrication/index.html), [Wyatt's fan](https://wyattroy.github.io/ps70/03_fabrication/index.html), <a href='https://sophiecwebster.github.io/PHYSCI-70/03_kinetic/index.html'>Sophie's flock of birds</a>, <a href='https://mila-barry.github.io/PS70/03_handtools/index.html'>Mila's Stormy Seas</a> </p>  <h3> Resources: </h3> <p> Modeling gears in Fusion from scratch is a useful exercise. But you can also use a script to help automate the process. The first half of <a href='https://www.youtube.com/watch?v=ZakT54JIhB8' >this video</a> shows you how. <br><br> Look up artists like <a href='https://www.youtube.com/user/dreamingmachines/videos' >Arthur Ganson </a> and <a href='https://www.youtube.com/watch?v=0_22x26qYPA' >others</a>. These pieces probably took more than a few days to complete, but likely many of them started with study models made from things like cardboard and simple DC motors. <br><br> Here is a fun old reference for mechanisms: <a href='http://507movements.com/' > 507 Mechanical Movements</a>, and <a href='https://www.fivehundredseven.com/'>offshoots</a>. <br>  </p> <h3> Resources: </h3> <p> <a href="https://learn.sparkfun.com/tutorials/what-is-electricity">What is electricity?</a><br> <a href="https://learn.sparkfun.com/tutorials/what-is-a-circuit">What is a circuit?</a><br> <a href="https://learn.sparkfun.com/tutorials/electric-power">Electric power</a> </p>
