PoE-powered lab power supply using a DPS5005 and custom PoE board
In this video I decided to take a DPS5005 adjustable power supply DC-DC converter (typically available from China for $25-$30 USD) and power it from a power-over-ethernet supply. I tried this with a cheap unmanaged TPLink switch, as well as a Cisco SG300 business switch and Brocade ICX6450-24P enterprise switch. The PoE using 802.3at tops out at about 30 watts of power, but that's sufficient for many lab tasks. For more electronics videos, see http://www.smbaker.com/
