3D printer used to make custom blade server type mounting system

3d-printed-blade-server-mounts

We usually have no problem hacking together electronics into something useful. But finding an enclosure that makes sense for the build can be a real drag. In this case [Vincent Sanders] already had a working ARM build farm that leveraged the power of multiple ARM boards. But it was lying in a heap in the corner of the room and … Read the rest

ARM powered rack mount USB test equipment

developing-rack-mount-pcb-testing-tools

This is a device which [Limpkin] has been developing at his day job. It’s a high-speed testing interface for use with Physics experiments. We find it interesting because it uses an ARM microcontroller to implement CDC and MSD over USB.

The design is in two parts to make it work in a rack-mount situation. That big white connector allows … Read the rest

Repurposing server PSU for your charging needs

That grey box at the top of the photo is a modular power supply unit for a rack-mounted server system. [Sebastian] decided to repurpose it as a charging source for his RC batteries. He chose this HP DPS-600PB because of its power rating, efficiency, and you can get them at a reasonable price.

This is an active power factor … Read the rest
