When we picture the Medieval world, it conjures up images of darkness, privations, and sickness the likes of which are hard to imagine from our sanitized point of view. The …read more Continue reading Hacking When It Counts: Surgery Fit to Save a Future King

It isn’t just that we’re cheap — although that’s probably true, too — but cheap boards are a good way to get people started on FPGAs and we think more people should be using FPGAs more often. One inexpensive board is the Max-1000 from Trenz and Arrow. At $29, it is practically an impulse buy. [ZipCPU] did a great write up on his experience using the board. He found that some of it was good, some was bad, and some was just plain ugly. Still, for $30, it seems like this might be a nice …read more
