This couples an iPod touch 4G to standard 23mm and 16mm tripod legs. This will allow you to secure a convenient mechanism to run iOS apps and control things that can be controlled with them through WiFi.
This is similar to a version I created for a Lumia 920 – but as there is still no ad-hoc WiFi capability for that platform, I have been using an old iPhone. I realised I had an iPod touch that was not in use – and so now this has been pressed into service to provide the remote control for my camera. It can live in my camera kit within the holder, as there is room for the power charger to connect.
