1 Lab 7: Team Project BMEn 2151 Introductory Medical Device Prototyping Prof. Steven S. Saliterman Exercise 7-1: Soldering Practice Clock Kit Objective: Learning to solder components to a printed circuit board. A box of clock kits is in the storage cabinet. You may assemble one individually or as a team. An instruction document for assembly and operation of the clock can be found on the website under Self Review items. Rather than powering from your computer USB, it is wise to first test operation using a separate USB charger source. Clock kit. Finished clock - populated side. Solder side.

2 Page 2 Exercise 7-2: Team Project Objective: To undertake further study of useful methods for medical device prototyping, and to present these methods to the class. It should be something that you can accomplish in about a three week period. There are different Project Boxes in the storage cabinet that you can use. Parts may also be picked up locally or ordered (note time constraints). Grading will be based the effort that went into your project and your presentation. Time will be assigned to each team at the end of the semester for presentation. You should also prepare a handout for each member of the class summarizing what you have done, including method and materials. Add pictures, schematics, parts lists, etc. as necessary. Anyone should be able to replicate your work in the future if they wanted to. a PDF of your presentation to Prof. Saliterman. Some projects ideas to consider: 1. In the Arduino Part 2 lecture we reviewed an absolute orientation sensor (AOS BNO005). Discuss the concept of sensor fusion, the data generated by this board and quaternions 2. Create a user interface for an Arduino project with MatLab. You can create any Arduino application, and show how MatLab can be useful as a user interface and for data acquisition. 3. Learn about water jet cutting, and present this technology to the class. Discuss with the supervisor in the ME Machine Shop. 4. Design a suitable part for demonstrating 3D printing with the Stratasys PolyJet printer. Print the part and explain the concept, technique, advantages and disadvantages relative to other prototyping techniques (discuss the costs of printing with me first). 5. Review Computer Aided Manufacturing (CAM) and give a demonstration of the software HSMXpress running on Solidworks. 6. Demonstrate a wireless interface application using any development board and one of the wireless modules e.g. WLAN or Bluetooth. 7. Incorporate recoded sounds and playback into an Arduino project.

Review the segmentation software ITK-Snap (free download) and Meshmixer (free download) for creating a 3D anatomical model from an MRI or CT scan. Print the model using 3D FDM printing. 10. Study and present 3D bioprinting, including methods and materials. Additional Available Project Items (Request from Prof. Saliterman) Printed Circuit Breadboard Solderable PC Breadboard This board allows you to take your breadboard design and port it to a more durable soldered circuit. I recommend using IC sockets for integrated circuit mounting. Use your board space efficiently; it is hard to unsolder ICs and IC sockets! Sensors & Actuators These items are in the storage cabinet for use with your projects or for just experimenting with (please return these items when you are done). You can find technical details on them by searching the internet (Adafruit, Amazon, Spark Fun etc.): Standard Size - High Torque - Metal Gear Servo 5V Delay Relay Module Delay Switch High and Low Level Trigger
