For this post I will walk you through a project with a Field Programmable Gate Array (FPGA), which was interfaced with a hand constructed clock circuit (an astable multivibrator).

If you were there you would have been blinded by the metaphorical light bulb that lit over my head. You see, just the week before, my friend and co-worker had ordered an old, decommissioned (complete with “non-classified” stickers!) Apple Xserve off of eBay for merely $40.
