I watch bigclivedotcom and once day he had a clock kit on there he put together so I decided I want one so I ordered a cheap one nothing like his linked below. Problem is once I finished assembly I attempted to power it with a usb power bank. it worked for about a minute, the ic got hot enough to deform the socket slightly then it died.
I believe my assembly was correct and there do not appear to be any bridges, any eletronical people care to guess what whent wrong here?
I was gonna use it too tell time but now I can't this makes me sad.
Buddy, it's a dollar fifty with free shipping... Order 20 of those. I can guarantee half will not work as intended. I used to be an enthusiast like you, but then I took an arrow to the knee... Wait, that's different... I used to deal with some of those hobby kits back in the day when I was dealing with actual electronic devices. They are just bad quality. Assembling the parts yourself from any electronics store will end up 20 times more expensive but it will work. Because the parts will actually be quality parts.
Basically use frequency generator and frequency splitters etc with other multi segment displays... If you have the design skills you could easily build your own...
