The iPad-charging Powered USB Hub Alesis IO Hack

untergeek

After reviewing dozens of available USB devices, guitar inputs, and obscure gadgets, I have given up the quest for a ready-made device that will satisfy my desire for a USB hub that charges the iPad, from batteries, while it hosts other USB devices. Currently, there is no such product. But one crafty, Dremmel-wielding hacker has created that very thing.

Untergeek tore apart an Alesis IO Dock and inserted a USB hub internally between the iPad and the IO Dock. It is almost as simple as it sounds if you know your way around soldering, hot glueing and warranty voiding. Here is a video on how to DIY it.

The Hubbub Guitar System – Part 1 – The Plan

Hubub-Feature

hubbub – noun – A loud confused noise from many sources.

The Hubub is a fitting moniker for our current iPad-based guitar system project; a melange of synth sounds, MIDI signals, analogue guitar, and the digital mayhem that ensues.

It’s doubly appropriate since a customized USB hub will be required to make it all possible, or at least practical. A primary goals of this setup is that it should run entirely from rechargeable batteries, sans power leads. It’s a lofty, but worthwhile goal. Over the next few weeks we shall see if that goal is achievable in a cost-effective way.

Powering the USB hub, and the devices attached to it, from a battery is easy enough. But music software tends to drain an iPad battery quickly, so we want to be able to charge the iPad while in use. There doesn’t appear to be a product available that accomplishes this goal without a computer somewhere in the mix.

But we are working towards a solution. Soon many, if not all, of the devices below will be happily hooked up to an iPad air, buzzing along from rechargeable batteries.
