// Heart-shaped 555 timer LED blinker  -  "Happy Valentines Day Mahija!"
// ---------------------------------------------------------------------------
// Power:    2 x CR2032 in series (6V) on the BACK of the board, soft-power
//           via a tactile pushbutton.  CR2032s give ~30 mA continuous which
//           is exactly what we need.
//
// Circuit:  Classic NE555 astable multivibrator
//   f  = 1.44 / ((Ra + 2*Rb) * C)
//   Ra = 4.7k, Rb = 47k, C = 10uF  ->  ~1.46 Hz, ~52% duty cycle
//
// LEDs:     14 x 5 mm through-hole red LEDs around the heart border, all
//           wired in parallel through ONE shared 56 ohm 0805 current-limit
//           resistor.  At 6V supply with the 555 sourcing ~45 mA, each LED
//           sees ~3 mA average -> bright enough for an indoor display
//           without taxing the chip or the cells.

// the far ends of the body.  We mount it on the BACK of the board so the
// front face stays clean for the silkscreen love note.
