Sound Isolated Server Rack

Servers are most often found in climate controlled data centers. This means they aren’t exactly built for creature comforts like quiet operation. Quite the contrary — many server chassis include fans which absolutely scream when the machine is under load. [Whiskykilo] needed to set up a 12 U rack in his basement for working from home. He knew the sound would get on anyone’s nerves, but especially on those of his wife.

To solve this problem, he built a sound isolated rack. The build started with a standard 12 U metal rack frame. This is wrapped in 1/2″ MDF coated …read more

Hackaday Prize Entry: Minimalist HTTP

For his Hackaday Prize entry, [Yann] is building something that isn’t hardware, but it’s still fascinating. He’s come up with a minimalist HTTP compliant server written in C. It’s small, it’s portable, and in some cases, it will be a bunch better solution than throwing a full Linux stack into a single sensor.

This micro HTTP server has two core modules, each with a specific purpose. The file server does exactly what it says on the tin, but the HTTaP is a bit more interesting. HTTaP is a protocol first published in 2014 that is designed to be a simpler …read more

The Silence of the Fans

The good thing about using a server-grade machine as your desktop is having raw computing power at your fingertips. The downside is living next to a machine that sounds like a fleet of quadcopters taking off. Luckily, loud server fans can be replaced with quieter units if you know what you’re doing.

Servers are a breed apart from desktop-grade machines, and are designed around the fact that they’ll be installed in some kind of controlled environment. [Juan] made his Dell PowerEdge T710 tower server a better neighbor by probing the PWM signals to and from the stock Dell fans; he …read more

Bench Power Supply Uses Server Voltage Regulator

If you stuff a computer into a rack with a bunch of other machines, you’d better make it a tough machine. Server-grade means something, so using server parts in a project, like this high-wattage power supply using server voltage regulators, can take it to the next level of robustness.

But before [Andy Brown] could build this power supply, he had to reverse-engineer the modules. Based on what he learned, and armed with a data sheet for the modules, he designed a controller to take advantage of all the capabilities of them and ended up with a full-featured power supply. The …read more
