I like creating electronics related YouTube videos. I mostly buy faulty gear from Ebay and make a repair video of it,
but it's expensive and so with your help maybe I can continue to do so.
If you have any faulty test gear you don't want or going cheap then please contact me. Your support would be greatly appreciated.
