Finally debugging an old project. It’s a mess but we can work with this.
Today’s video is about a package sent in by 1BitSquared with a prototype FPGA board. These boards are part of a new generation of open hardware which builds on a foundation of open source FPGA tools. At the time we streamed this live, the crowdfunding campaign was about to launch. It’s been successfully funded, and at this time you can pre-order boards from the next batch.

Continuing the adventures from Part 1, this video wanders along several tangential paths, trying to get some data out of this device worthy of reversing. This time we spend a bit more time in IDA looking for Z80 code, tinker with SCSI trying to break things, and we even do some necromancy in trying to get grumpydisk working.

This time I find something in my junk drawer with a few teeth marks on it, and it leads to a weirdly specialized CPU built on a super oldschool core.
I take apart a Pyle PDWM1940 wireless microphone receiver, searching for a way to make the output less noisy. Meanwhile, I’ll be using the same receiver for filming.
My friends at Tangible Interaction sent some electronic whiteboard hardware to take apart. In this video I’ll start to look at the transmitters, receivers, and communication protocol.
