The Apple Bluetooth Magic Trackpad and wireless Keyboard are great products. Unfortunately, they consume a lot of batteries and always seem to go dead at the worst possible time leaving you scrambling to find fresh batteries.
In an effort to keep batteries out of landfills and make owning these devices more cost effective, we thought it would be great if they had the option of being powered via a USB port. So in January 2012, we got to work.
After a few design iterations, we came up with a sleek one-piece design which is not only economical to make, but looks good too. This design is compatible with both Apple wireless keyboard (the two AA version) and Magic Trackpad. You'll never have to raid your TV Remote for batteries again.
How does it work?
The power adapter replaces the batteries and the battery cover "button" on the wireless keyboard and TrackPad. Simply remove the AA batteries, slide in the adapter, then twist it to lock it in just as you would the original battery cover. Plug the attached USB connection into a USB port on your computer or into any USB "wall wart" charger for an endless supply of power. There are no drivers to install as peripherals still use Bluetooth to communicate with the computer. When you turn off your computer, the USB ports shut down, so there is no need to remember to turn off your Trackpad or keyboard. If you want to go wireless again, simply swap the adapter out for some batteries and the original battery cover.
Under the hood...
Internally, the adapter contains the proper electronics to regulate the 5 volts from the USB port down to the 3 volts needed for the keyboard or TrackPad. It utilizes high quality surface mount low dropout voltage regulator and filtering capacitors. The end cap is milled from high quality stainless steel to match the look of the original battery cover, and the extension tube is milled from 6063 aluminum. All parts are sourced or manufactured in the USA.
Why we need your support...
All the mechanical and electrical design work as well as the prototype is done, but manufacturing an elegant replacement battery cover is not cheap. Notice our emphasis on it being elegant? We believe our products should seamlessly compliment Apple's style and design. So, in order to make this as affordable as possible, we need to place a large order and buy parts in bulk. With your help we can start production very soon!
Some people are using the Apple wired keyboard and would like to plug the Power Adapter to it instead of into the comptuer. So there is no need for a 3 ft cord. Everyone will have the option to select how long they want the cord to be. We will send out an email after the campaign closes to ask for the details then.
