You kids, your wife, not even that pesky burglar will know it's there.
This instructable will show you how to turn the dead UPS Power Backup into a discreet external hard drive for under $20.00!
Watch the video for the overview:
Step 1: Supplies
- Broken UPS with USB port
The one I used had a standard type B plug, but you can also use the type that have an RJ45 instead.
It doesn't have to be broken, but there usually isn't enough room inside for the battery plus the hard drive and USB converter PCB.
- Used laptop hard drive
Don't use one that is too large, as the single USB port may not be able to supply enough power.
I found a 20GB drive on Craig's list for about $10
- USB 2.0 Enclosure for 2.5" Laptop Hard Drive
I found one made by MSI at Micro Center for $9.99.
- Soldering Iron, OHM meter, screw driver, wire cutters, etc...
Step 2: Open the UPS
WARNING: there could potentially be residual voltage inside.
The UPS I used had 6 screws holding it together, and another two holding the PCB in place.
Most of the wires to the transformer and other circuit boards had easy to remove plugs as well.
When you get the PCB loose, flip it over to get at the USB port solder connections.
Step 3: Trace the USB connections.
You'll need an OHM meter with a continuity check, or some other type of light bulb continuity checker.
First, plug in the USB cable that came with the UPS. Use the OHM meter to determine which solder pad on the bottom of the PCB goes to which pin inside the other end of the USB cable.
In the case, the wires were 4-3-2-1, from left to right, looking at the end of the cable.
