Nearly done with our family project.  It has been so much fun, and I hate that it’s nearly over, but Eli and Addy are pumped for another project.  The maker space  has been the new cool hangout:  loud music, chips + cheese dip, Teen titans Go, roller skating, and making a killer boom box that everybody loves.

the brains is a trinket Pro 5V 16MHz

This is my first project with a trinket Pro.  I love this platform.  Tiny, cheap, powerful,  easy to use; comparable to an arduino nano.  I did run out of GPIO pins (mostly due the the 16×2 LCD display), but got around it adding an MCP23008 for the alarm control buttons (also using libraries from adafruit) .

It’s adisaster on the inside, but pretty cool on the outside.
