I just did a self-assembly of JTAGulator. This simple and amazing device indeed works and shortens JTAG pinout search from days to seconds. AMAZING! I have some spare devices to sale cheap in EU, if you want one let me know! 🙂

JTAGulator is an open source hardware tool, created by Joe Grand / Grand Idea Studio, that assists in identifying OCD connections from test points, vias, or component pads on a target device. All you need is a target device, bunch of tap wires / cables, USB-Mini cable, and serial terminal to operate JTAGulator.

On-chip debug (OCD) interfaces can provide chip-level control of a target device and are a primary vector used by engineers, researchers, and hackers to extract program code or data, modify memory contents, or affect device operation on-the-fly. Depending on the complexity of the target device, manually locating available OCD connections can be a difficult and time consuming task, sometimes requiring physical destruction or modification of the device.


I have found very simple solution on how to access YouTube videos that require Flash using HTML5 player. Although front site may not support HTML5 video player, YouTube usually allows to embed videos to other sites, they also should use WebM codec developed by Google. If you have a video that does not work in HTML5 by default try to run it in embed player by URL modification – replace “/watch?v=” with “/embed/” and it should work! 🙂
