Not much get's posted to this board, so when I seen this, I had to link it here.
I haven't really done much FPGA [Field Programmable Gate Array] mostly because I can't just go and buy a bunch of shit to start messing around with. FPGA, for those who have never heard the term is basically using configuring your own hardware logic to a chip. Or, eli5, make your own cpu's and other such things.
This site lets you simulate and play around with it in your browser, no downloads or anything, just open it up and start messing about with logic. The digital frontier of bare metal.
