"Simon's a computer, Simon has a brain, you either do what Simon says or else go down the drain!"  Nearly everyone has heard of the Simon Game first introduced in 1978 by Milton Bradley Company, now a division of  Hasbro Toy Company.  It is a game of memory skill played against a computer, with selectable game modes that can challenge the sharpest of minds.  SimonSense is a variation of the Simon Game, but uses LEDs as buttons instead of mechanical buttons...

Nixie Tubes in calculators were first introduced in 1955 by Borroughs Corporation, a company my father worked for.  In the 70's I acquired a Borroughs Nixie Tube Desktop Calculator, but it got disassembled with worthy parts donated to the junk bin.  I've been tinkering since elementary school and so my junk bin grew pretty large over time.  One day I had this crazy notion that all this antiquated stuff is just taking up way too much space...  

Have you ever hooked up one of these Sparkfun 2 line 16 character per line LCDs on a breadboard?  It takes more microcontroller I/O than you want to let go of, and is not quick to wire up either.  These LCD's use an HD44780 parallel I/O data interface chipset, and are useful for software debugging and displaying program information.  It is true that the same job can be done with a PC connect to the Arduino USB serial port, but an embedded LCD is far more portable.

The OneVane Click-Clack Clock was challenging in two ways.  First it was challenging to find simple circuitry to independently drive each of the seven segment magnetic vanes.  The second challenge was listening to the clock for any length of time... it will drive you crazy... more on that later! 

The OneRing WiFi RGB Light came about out of a desire to automate electronic devices in my home.  It started about a year ago installing Home Assistant (HA) on a Raspberry Pi 3.  What attracted me to HA?  Well there are a few thoughts... so hear me out.

The OneNixie Grand Clock is a simple, elegant, and unique single digit Nixie Tube clock housed in a 4" x 7" glass dome on an oriental rosewood base. The Nixie Tube softly illuminates a sequence of four digits displaying hours then minutes.  It was on display for a while at the Lake Mary Hyder Art Gallery, when it was opened.  This gorgeous Nixie Tube is made by Dalibor Farny!
