Nathan Jones' design portfolio includes summaries of three projects: 1. A test fixture for micro-scale measurements that uses a double-cantilever beam design and Hooke's law to determine how hard materials are being pushed. 2. A dry erase marker vending machine accessed with a Pitt ID that uses RFID, stepper motors, and an Arduino to select and dispense markers. 3. A video game called CaveTrekker that allows visually impaired users to play games using tactile and audio feedback without visuals by orienting the user and communicating messages through a control lever and sounds.

- 1. DESIGN PORTFOLIO for Nathan Jones
- 2. TEST FIXTURE for micro-scale measurements
- 3. Summary Task Determine how hard we are pushing on a material (in nN and mN) Purpose Understand adhesion characteristics of various materials UtilizedTheory F = kx (Hookes Law) F = How hard were pushing (Unknown) K = Inherent spring constant of a cantilevered beam X = Measured displacement
- 4. Summary (Contd.) Method Double-Double Cantilevered Beam Design OpposingCantilevers: Prevents lateral movement as beam is deflected Two-Layers: Prevents angular deflection at beam tip 3D Model of the Beam Assembly showing carbon fiber spacing blocks
- 7. Roles & Exposure 3D Modeling Manufacturing -Manual mill -3D printing Project Manager ANSYS analysis Design revision & prototyping Engineering theory calculation
- 8. DRY ERASE MARKER Vending Machine
- 10. Project Summary Task Create a mechatronic device that would benefit the University of Pittsburgh in some manner Purpose Provide engineering students access to dry erase markers Method Accessed by Pitt ID, allows user to select marker color and quantity 3D printed tumbler selects marker from hopper and accurately dispenses it
