RGB LED and vibration motor driver board mod

Because of the pin-out of the SMD RGB LED we are using (MODEL NO: 5060BRG4 datasheet), i think it makes sense to choose the following AUX port connections:
Green = Aux0
Red = Aux2
Blue = Aux4
Motor = Aux6

Because of the 100mA current limit of the x-IMU:
– Light flickers when motor is on full power
– And white turns pink when motor is on full power

Internal Pull-up Resistors on x-IMU????

Plan is for Seb to figure out either:
– Use internal pullups and scrap extra circuitry
– Seb designs inline pull-up PCB with SMD mounted IDC connector

Low-profile surface-mount resistors for in-line circuit:

In-between Finger Sensor

Modifying design to move one bend sensor from ring finger to between ring and middle finger, to measure the distance between them.

Altarnative to bend sensor: use Hall Effect Sensor for measuring distance between fingers?

After Dinner Notes

Trying on new gloves for fit

Videos of decorative lights

List of Things-to-Do
– Test decorative LED lights: embedding and control using arduino mini via x-IMU AUX port control
– Update glove wrist-band design to include x-IMU neoprene wrist tray, wired LED connections and vibration motor
– …

Saturday & Sunday

Video of gloves with differently mounted in-between finger sensors. Left hand: ring (Imogen is married to her gloves). Right hand: generic (nothing special).

Graphing in-between sensor values to compare and decide which works (and looks) best:

Driver Board

Using Seb’s to-scale driver-board print-out we decided that we would like the board to face down/over the x-IMU. Since the board is also slightly larger (than the pull-up resistor board) this also helps eliminate strain on the connectors (board to board) from anything that might catch or push against the driver board… we remain open to suggestions.
