Servo Actuated Gauge: Part 2

I finished up the wireless servo actuated air pressure gauge. The last things remaining were to finish the transmitter, and make a small transmitter box to house the transmitter PCB with a dial and markings corresponding to the servo actuated gauge. 

RC Servo Actuated Air Pressure Gauge

As part of my Undergraduate Research Opportunity (UROP) at the Computer Science and Artificial Intelligence Laboratory at MIT, I took apart an air pressure gauge and added a servo to remotely move the needle. I hacked the parts used in the air pressure gauge to make a four-bar-linkage with a servo I crufted from the remains of Charles' 2.00GoKart class. I'm not sure if I can reveal the intentions of doing this for secrecy of the CSAIL project, so I better be safe and not mention it.
