GROUND TRUTH GLOVE (adding Flex sensors)

An upgrade to the hall-effect glove.

[COMING SOON]

BOM

Prepare flex sensors

flex sensor

cut glove/ stretchy fabric

Grab the other glove you haven’t used yet (or any stretchy fabric) and cut out the fingers into strips, as long as they go. Keep these aside.

bend sensor

duct tape at the end, with some extra

fold it over

put into finger/ cloth

Then put the flex sensor about halfway on a piece of duct tape so there is a good amount of excess. Insert one of the flex sensors into a finger strip.

sew the end, through the duct tape. do not sew through the sensor

Sew the fingertip of it through the duct tape to keep it in place

sew around the sensor

cut off any excess

Sew around the flex sensor, ensuring it is not too tight as to not bend it. Cut off any excess.

push up cloth

Pull back the cloth and solder some wire to the ends of the flex sensor, then heat shrink them.

wrap wire around pin

solder both wires in place

heat shrink sensor

hot glue ends

NOTE

This bend sensors pins are bad, so I had to secure with hot glue. Probably better to use a different kind, these are what I had. Maybe they would be changed in the future.

You can now pull the cloth back down if possible. Repeat for the remaining sensors.
