LCD Hacking - Part 2 - Some Assembly Required

With my surgically extracted LCD panel and Amazon delivered LCD driver in hand, it was time to bring my repurposed LCD screen to life.

The LCD driver package came with a selection of random parts:

The only thing resembling instructions was a product screenshot labeled Wiring Guide:

I suppose a more cautious soul would have researched and carefully understood the role electronic component, and thoughtfully assembled them. Instead, I played a game of 'hey, what fits where?' and before I knew it, I had all the parts connected. The wiring diagram appeared to confirm my assumptions.

I then made my way to my defunct hardware pile and started looking for a 12 Volt, 3 amp adapter that would power this sucker. Despite a ridiculous number of adapters to choose from, I came up empty handed:

I should have been content to leave well enough alone and simply ordered an adapter off of Amazon. But no, I had to push my luck. I found a 12 volt 5 amp adapter that fit and decided to give that guy a go. This was almost certainly a very bad idea.

The little red LED did light up, but other than that, nothing happened. Did I burn out the whole system due to be impatient? Probably. I've ordered the right adapter and it should arrive in another few days. I guess I'll find out then.

For now, a wired heap of electronics is all I've got to show for my handy work. But I'm not ready to give up yet!

Stay tuned...
