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.

GlowBoard: A Welded Steel Mini-Skateboard

Inspired by Ben's PocketBoard, I decided to make a small skateboard in order to scavenge free food faster. It all started when my roommate crufted an old skateboard from his fraternity. I went on Ebay and found some awesome glow-in-the-dark 70x51 mm skateboard wheels. I wanted to make the deck such that I could maximize the visibility of the wheels. I recently learned how to MIG and TIG weld (thanks to Mars) and after finding some steel rings in MITERS' scrap metal I decided to practice my welding technique (before welding together my future electric motorcycle). I made a wire-frame deck with supporting steel rods underneath and the negative piece of a water jetted steel wrench for the truck plates.
