Ben Heck's FPGA LCD Driver Hack Episode -- Episode 169

This episode has been one of my favorites.... it got me to spurge on dev boards as I scrounge for displays in the scrap heaps around the area.

Suggestion, kind of in line with first comment about the logic analyzer, and this has to do with a recent project of mine.  I needed to decode the rf signal from my woodshop dust collector remote so I could make a bunch of cheap remotes for my shop and for friends with similar dust collectors.  I used channel 1 of my scope, similar to how you decoded the video signals in this episode.  It was tough for me to gather the info I needed to replicate the binary code from looking at channel 1.  So I tried a logic analyzer and that greatly improved capturing and analyzing the signals - I captured and dumped the data into a spreadsheet for analysis.  This method helped me rapidly decode and replicate the signals.  Below is a pic of my setup with a spreadsheet print.

Another suggestion, this is for your pinball machine.... I might try building this myself.... video capture for the fpga system.... so, when someone triggers a significant event on the pinball machine the fpga system would rapidly capture facial expressions of the player using some pic/video camera and flash them on the display during intermissions or for high score images.

I look forward to watching your show every Saturday morning.  Thank you for all that you do!
