I met Paul Soulsby at Superbooth16 in Berlin, earlier this month.
Paul has developed an amazing piece of hardware based on the ATmega328P: The Amagatron

Paul also developed a software to allow applying code without the hassle of using the Arduino IDE, installing libraries and compiling code : EasyUploader

Paul made a special version that supports the reset timing that Talko requires.

So have a look on the Downloads page to see how simple it is now to apply new versions of  code to Talko.

EasyUploader is really … easy to use and works both on Mac & Windows.
