Initially I’m going to put most of my photos and videos here, and then I may add parts lists and details. If you want to build one, start with the article on Makezine. I wanted to add some visual and tactile steampunk type features, as the kid I was building for is pretty interested in mechanical detail and I thought she would appreciate it. When initially explaining it to my 3.5 year old granddaughter, she is also the one who asked what does it do if it finds a monster?  Can it kill it?  That prompted me to want to add a “kill” switch as well as sound when it’s scanning. Then, I felt it deserved a good case, so the matching Pelican 1200 was modded.

I am pretty mechanical and a solid DIY homeowner and DIY vehicle mechanic. I knew how to solder, but had zero experience with Adafruit, Arduino or anything like that although I am an IT person by day.

Here are the published video links of the project, followed by the photos. Jump to the bottom for the list of sources and products I used, which is still incomplete.
