===== Week 8 ===== ==== Meeting Minutes March 7, 2019 ==== **Attended: Mizpah, Sharmaine, Xiao** === Updates === * Got back our order forms signed by Dr. Kuh and uploaded it to Laulima * Conducted range testing: Different floors - Board suddenly turned off --> battery died - changed the battery but didn't power on --> checked voltage going out from the voltage regulator and it was 5V! - changed the voltage regulator to Pololu 3.3V voltage regulator --> not regulating to 3.3V - accidentally connected it backward --> it got HOT!! [MIZPAH GOT BURNED! ): ] - Since the battery is only 3.4V, decided to just not use a voltage regulator (temporarily) * XCTU RANGE TESTING NOTES: - Local = XBee module is connected to the computer - Remote = other XBee in the same network (not connected) - RSSI values (dBm): < -80 dBm = poor ===To Do=== * Conduct more range testing * Waiting response from Dr. Sasaki to send Gerber files to Linda ==== Meeting Minutes March 8, 2019 ==== **Attended: Mizpah, Sharmaine, Xiao** === Updates === * Continuation of range testing: Line-of-Sight - Used LM1086 to regulate the input voltage to 3.3V - * Still waiting for order confirmations from Linda - Mouser: Solar Lithium Ion/Polymer charger, XBee Pro S2C - DigiKey: SMD Switches/Button, 0805 18 pF capacitors - Seeed: PCB ===To Do=== * Continue range testing for not line-of-sight
