USB Power Hack, Adding Usb Ports to a DX052 Mixer

This is another usb power hack. It demonstrates how to attach a couple usb ports on a DX052 mixer board for powering your ipod(s) or any USB device. I bought this mixer recently and love using it.

The following equipment can be bought at just about any radioshack or electronics store.

Electronics:

• Soldering Iron
• 2 10K resistors
• LM7805 +5V voltage regulator

Other equipment:

• 2 port USB connector with pci bracket (taken from a computer case)
• drill and bits that can cut through metal
• rotozip

The DX052 comes apart very easily, unscrew the top and disconnect all cables. The cables that connect the mixing controls to the power supply are socket connections.

With a multi-meter find a connection near the power supply to pull DC voltage. The one I used was 16v. Carefully solder a wire to it to feed the voltage regulator.

You may want to lay this out on a breadboard first. Make sure you connect the pins to the LM7805 in the right order.

The pull up resisters for D- are required for some ipods charge but aren't needed for most usb devices.

There is plenty of room. I conveniently mounted the LM7804 on the ground tap.

Strip the USB connector and solder GND, 5v, D- and D+ to it

With a drill bit that can cut through metal make holes for the usb screws and connections, fill them out with a rotozip or dremel.

Cut the PC USB PCI slot bracket on both ends.

Attach the USB bracket and connect the USB ports.
