5. Design Challenges Flex Sensors – Conceptually great, actually terrible Wear over time Needs Calibration Easy to break Next time – potentiometers or accelerometers IR communication Best way to send from glove (has to stay put) Raspberry Pi hub Control lights Simple method was chosen over X10 or similar... Many more!
