Recently I purchased from Ebay & just recieved today an LED level meter kit. Allthough it is intended for 2 ch I thought with some re-purposing I could get it to display more chs for a surround sound indicator.
See? Pretty cool. I am pretty savvy kit builder & I figured this would come with minimal but usable hook up directions. It came with exactly zero hook up schematic or directions. Besides the ribbon LED strips the main component is a 8A4K32S2A12 chip which is a 8-Bit FLASH 8051 24MHz 2V memory. I have absolutely no experience with this, no way to tell if it is programmed to do something at the factory or if I'm supposed to do something with it. I have found the data sheet but haha it's only in Chinese! On top of that it's a teeny surface mount device with 12 pins on each side. I guess it doesn't matter what I know about it's application because I have to way to solder something that small anyway!
In all fairness to the seller it shipped promptly and the kit was exactly as described, no more, no less. So I'll give some more thought to it but at the worst it's not like I haven't wasted ~$20 before.
If anyone runs across any further info I'd sure appreciate it!
