This is a PCB for a game that I made. The object of the game is to stop the cycling LEDs at a specific LED to test your reaction skills. The TI MSP430G2231 microcontroller drives 8 LEDs via 3 pins using a 74HC595 shift register. The speed that the LEDs flash is determined from the potentiometer wiper via the analog to digital converter in the MSP430. There are also 2 pushbuttons to start/restart and stop the game. Everything is powered from a 9V battery that is dropped down to 3.3V via a LD1117V33 voltage regulator. There is also a programming header to program the microcontroller in-circuit with a TI Launchpad. More details at: tinkeringetc.blogspot.com.
Please contact me with any questions. I'll respond as quickly as possible!

My girlfriend lovingly refers to me as a "tinkerer” because I spend my free time designing and building electronic circuits. I also have a Printrbot 3D printer and enjoy creating objects layer-by-layer. I love microcontrollers and writing code (and learning new programming languages) and have many hobby projects that take advantage of that. I have more ideas than time so I’m always switching between projects. I love taking a project from an idea, to a design, to a physical product. Nothing beats having a functional device that you've worked on from start to finish.
I graduated with an electrical engineering degree from the Pennsylvania State University. I am now an employee at Hughes Network Systems working in the hardware division creating and testing new designs for broadband satellite modems.
