But there’s some good news now: the company has decided to open source the hardware, making it is possible to build your own dongle. I see this as a very good approach in phasing out a product – make it open source.
The design files for the Mobile Dongle now on Github. I like this open source approach.

WHY IT MATTERS TO YOU
The thousands of photographers using TriggerTrap remotes may not be left with a useless device after all, with open source code designed to keep the apps functioning.
TriggerTrap may be shutting its doors, but chances are, users might still be able to use their devices even on operating systems that have yet to be launched, thanks to the company’s move to share the app as open code.
