A really cool little device. I've got plans to use it in at least one upcoming project. You can find them here (this is an affiliate link): ebay.to/2aQK5Sk
These can be found for as little as $3, but if you purchase one be careful that it comes with the plug in power supply if you don't have one already. This video was not sponsored. I purchased this of my own accord and am not speaking for any one brand over another.
