2015-10-22 (Th) Wrist Mounted Chording Keyboard

A micro USB port was attached purely as a power supply port. Soldered wires on the breakout board broke while testing so a firm mounting location seemed important. Screws were used to mount the USB port for the keyboard but required a standoff and placing the device closer to an edge would have eliminated the need for standoffs. In this case the port was glued to the lid of the enclosure. If any problems arose from this configuration the port and lid could be replaced as a unit and the wires running from the USB port could be taken out of the screw terminals. Since no more testing would be done the curing time of the glue was acceptable while screws or bolts would have been necessary to continue testing.

Construction was nearly completed. An assessment needs to be taken to recognize what problems still need to be addressed. For example: the cord between the emitter-receiver tube is too short.
