External Power Pack– allows us to externally power a device through USB to extend device running time.

The external power pack was very kindly provided by Gomadic (www.gomadic.com) as a way to help us power any devices that may need a longer running time over the course of the flight.

The flight duration is likely to be around two and a half hours long so keeping the devices running is essential.
Luckily, the GPS has an extremely long battery life and so we only need to concentrate on keeping the cameras running.

It uses a high capacity rechargeable battery technology (17 Wh / 3400 mah) in a compact design (2p in picture for scale) and weighs around 100g.

A series of LED indicators shows me the current battery level of the power pack.

The output has an exchangeable tip, which allows me to use the pack for different devices. An idea is to use a USB port splitter for the different devices.

The power pack will be tested with our cameras and devices before we send it up to make sure that it provides enough power for the duration of the flight.
Previous calculations on paper have shown that it should be suitable as we have to take into account the device battery as well.
Heat produced from the power pack will also help maintain a better temperature for the equipment to operate in.

Gomadic leads the electronics accessory market with products that innovate beyond traditional designs. Their goal is to provide high quality, convenient, inexpensive and upgradeable solutions to keep pace with the rapidly changing mobile device marketplace.

Thanks to Gomadic for the help and support with the project.

As we’re only at the beginning of the design and build process, we may encounter problems or decide to change the design based on other factors. We’ll try to keep everyone updated on the changes and will explain why we have done so.
Please leave a comment or if I have missed any vital information, let me know and I’ll edit it!
