Finished Glove, Demo, and Next Steps

We finished building the entire glove on Tuesday night.  This involved trimming the leads coming from the flex sensors, soldering all the grounds to one common node, attaching resistors and ADC leads, and connected the resistors to one Vdd node. This proved a little more difficult than expected, simply because of the small space we were working in.  In addition, we attempted to lead the wires to reinforce the extra stitching we did to keep the flex sensors in the optimal flexing area.  After some testing, we realized that the thumb and pinky in particular weren't really placed well.  To rectify this, we added extra stitches to keep them in place.  We also reinforced the other sensors to ensure a tight connection.

As a side note, every wire is color coded.  :)  Red = Vdd, Black = ground (of course), Blue = flex sensor connection, orange = ADC connection.


We demoed our glove on Wednesday to Professor Mangharam.  We showed him the finished glove, and the ADC values on the terminal.  We were able to show him the ranges of ADC values we were getting and the hopefully big enough margin between straight and bent.

Next, we plan on decoding a couple of letters, starting with the simple ones (A, for one).  We'd also like to get wireless transmission working.  We've been forced to do all computation on the node connected to the glove because the other node wasn't functioning.  We have since gotten more nodes, and hope to get this working so that the glove isn't tethered to the computer.
