Gallery – Hobbyduino XBee Plug V1.0

I’m pretty sure the majority of my projects will never be considered “Complete” as I’m always tinkering with the firmware to add or refine features.  However, I like to give my projects a finished look which means they will be inside of enclosures or integrated into other devices.  It would be nice if I could update the firmware without having to dissect the project to get at the controller.  To accomplish this, I created a XBee plug for my Hobbyduino Mini V3 Arduino clone.  Check out the gallery here and the tutorial here.

Gallery – Hobbybotics Photo Interrupter V1.0

I uploaded pictures to the gallery of version 1 of the Hobbybotics Photo Interrupter based on the CNZ1120. I screwed up a bit when I designed this board as I created the footprint for the CNZ1120 photo interrupter backwards. It still worked out in the end and I actually like it this way as it allows me to place the interrupter on one side of the board with the rest on the components on the opposite side.  I also screwed up a bit in the schematic with the placement of the LED.  This little mistake was fixed by simply removing the LED and associated resistor from the final board.  In the end, it still works!
