Picture of Light up your Robot T-Shirt
Here is a fun and easy soft circuit project. I took an Instructables' Robot t-shirt and added some LEDs for the eyes and a flashing red LED for Robot's heart.  The switches are situated where the grey buttons on Robot's front panel are.

The circuit is sewed onto felt  that is attached to the inside of the t-shirt with Velcro so it can be taken off and the t-shirt can be washed.

Step 1: What you will need

Picture of What you will need
  • Instructables' robot t-shirt (you can win one, or buy one here)
  • Felt: red and white for the heart and another piece for the circuit panel
  • Velcro
  • Matching thread
  • Pins, needles and scissors
  • Needle nose pliers
  • Washable fabric glue
  • Tape
  • Conductive thread (I bought mine here)
  • LEDs for the eyes (I used some yellow ones which I got from cheap set of battery powered Christmas lights)
  • Two push button switches
  • Resistor (use  this site to determine which one you need) 
  • Button cell battery
  • Flashing red LED circuit ( this I got from cheap flashing dollar store toy or you can make one)

Step 2: Prepare T-shirt: Eyes

You will need to cut holes in your t-shirt for the eye sockets.  Place your L:EDs over the eyes and gauge how big the holes need to be.  It is better to have the holes fit snugly around the LEDs, if they are too big the LEDs will slip out of the sockets when you move around.

Step 3: Prepare T-shirt: Heart

Picture of Prepare T-shirt: Heart
Robot tends to bear his heart only around Valentine's day, but I wanted this t-shirt to have more going on than just  LED eyes so I added a beating (flashing) heart.  Robot's heart can be seen when a chamber is open on his chest.  So you will need to cut a square with flaps opening out on both sides.

The circuit is on a removable panel so you can wash the shirt.
