2. Know the Spirit, Live the Spirit Flickering lights Shaped like a hockey stick and puck RPI Colors Fun facts about the Red Hawks

3. Processes used: 1. Injection Molding 2. Powder Coating 3. Laser Engraving 4. Ultrasonic Welding 5. Metal Forming 6. Abrasive Water Jet 7. CNC machining 8. Soldering

4. 2-D base and the 3-D cover (hockey stick shaped) 1. 2D base- Abrasive Water Jet (cut out) - CNC machine (switch opening) 2. 3D cover – Abrasive Water Jet (cut out) - Metal Form (to give it some depth) 3. Attach using ultrasonic welding

5. Circuit and Switch 1. Button Battery 2. Wires 3. Slide Switch 4. LEDs Wires and switches can be soldered to strengthen circuit. (Alternative) Changeable batteries and custom switch

6. Clapper 1. Puck holder with slots and middle puck (plastic injection molded)- transparent lumogen dye 2. Two side pucks (plastic injection molded)- red lumogen dye

7. Clapper 1. Attach pucks and holder (ultrasonically welded) 2. Attach the clapper to base

8. Why make it? 1) Variation of processes (almost all in MILL) 2) Basic circuitry and soldering(challenging and interesting) 3) Alternative custom switch and circuit design (involved electronics)

9. Proposed Customs and Design 1. The two outside pucks carry the symbols of RPI (powder coating). 2. The hockey shaped aluminum base is powder coated with black and white stripes. 3.
