DIY OTG Cable dongle – 30/08/14
An OTG (USB on the go) is a dongle that plugs into an Android device and offers an external USB port.
Stripping the wires was fairly simple and straight forward. Connect the yellow with the ground (messy silver ones) and black wire. This allows the device to be set as the Master. Without this step, the device will remain as a slave.
Stripping an end of a USB-A cable, I exposed 4 coloured wires.
You can see the mouse cursor as I connected my Logitech mouse to it.
ISSUES: The hub takes too much power (the purple light). As a result, the Nexus 7 2013 cannot power up the mouse receiver. However, it will work with the Moto X and G (tested).
Also, the micro USB plug is a little off, which means you have to apply a bit of pressure a certain way to get it to work.
In the end, this dongle was semi functional, and very bulky. It isn’t worth it to purchase the material to produce this dongle. You are better off spending $1 on eBay.
