Designing and building an FPGA sprite-based graphics accelerator (2014)
A very warm welcome to my most ambitious project to date. In this project I’m going to attempt to design and build a sprite-based graphics accelerator that will function as a co-processor to an MCU. Using cheap off-the-shelf components I’m hoping to achieve a level of gaming performance that compares well to popular…

Every 7.8μs your computer’s memory has a hiccup
I was particularly interested in one of the consequences of how dynamic RAM works. You see, each bit of data is stored by the charge (or lack of it) on a tiny capacitor within the RAM chip. But these capacitors gradually lose their charge over time.

Fast line-following robots
Since February 2016, I have been participating in DIYRobocars meetups here in the SF Bay Area, wherein a bunch of amateur roboticists compete in autonomous time trials with RC cars. I had been doing very well in the competition with essentially just a glorified line-following robot, but have lately upgraded to a full…
