Here’s something that will probably make it to a wall right next to the people responsible for the Hackaday servers sometime soon, and should be something every web dev should build at some point: a website response meter, an analog gauge that will tell you how long it takes to reach your website.

The build is simple enough, with a micro servo working as a gigantic analog gauge. There are also a pair of four-digit, seven-segment displays for displaying a digital number and the number of website requests per second. There’s also an 8×8 matrix of bi-color LEDs for showing a green happy face or a red frowny face, just in case all that data wasn’t self-evident to the uninitiated.

All the electronics are handled by an Arduino, but what really makes this build useful, or even possible, is the bit of code that runs on a computer. The computer uses an API from New Relic, a software analytics company, to come up with the response time and requests per second. That data is pulled down and piped up to the Arduino that displays everything on a beautifully milled acrylic sheet.
