Shown here is our eBookmark at a more advanced stage. The basic idea of operation is that a user will mark their place in a book with a touch strip and it will be stored and displayed via the embedded LEDs. A toggle switch at the top of the device selects the left or right page of the book. The indicator sleeps after 5 seconds and wakes up to display the last saved bookmark upon the next touch of the strip or toggle switch.
All of the electronics including microcontroller, white surface mount LEDs, resistive touch strip sensor, tact switch and lots of teeny tiny wires are embedded in a carved 7” x 1” x 1/8” basswood body. The front panel is a temporary proof of concept. The microcontroller code was written in pure C and compiled with avr-gcc. Getting all of these small parts wired into such a small and delicate wooden frame was no easy task. The most trying moment was when I realized I had initially installed all 16 LEDs backwards :| However, it’s already looking pretty rad at this point and I can’t wait to finish and show the final piece!
