This is a DIY OTG Cable Warning. I am a great advocate for Do It Yourself but several phones belonged to colleagues and their friends have come to grief in the last few weeks.
This morning I informed of a 4th Android phone which was apparently blown by a homemade OTG cable. The On The Go USB cable provides the android phone and Raspberry Pi Zero with a full size female port. You can read up on the possibilities the OTG cable offers the Android phone user. Unfortunately, in one case the phone is now useless and cannot be charged and the remaining three units are freezing or rebooting without warning. Personally, I believe it is not worth the risk unless you know what you are doing and have a suitable soldering iron with a precisionl tip. A big poker style iron will do more damage than good.
Bearing this in mind I have removed my DIY OTG Cable video page from the site. All inline plug and socket USB pin-out diagrams have been deleted. If you insist on making your own cable there are several videos available on YouTube but I would advise caution.
If you are really in a hurry to get your hands on a OTG cable it is available in Harvey Normans for €10. OR if you are in no hurry and can wait a month or so you can purchase one from China on eBay for a €uro with free postage included.
