hall of fame


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.

It is my great pleasure to inform you folks that, almost after four years, I did a new release of LibSWD-0.7 [1], a low-level embedded systems access open framework. Special thanks goes to Andrew Parlane of Carallon Ltd [2] for his much appreciated contributions! Well now I feel like I need to invent some nice small device based on ARM Cortex-M0 CPU 🙂

Google have implemented my idea to make Google Books TTS work like an audio player – it can now work in background and being controlled with bluetooth headset – so I can play, pause and rewind paragraphs of the book read by speech synthesizer just as it was music. This is soo fantastic!!

I have been proposing this solution to Amazon to implement in Kindle for Android, but for years they did not listen. I have switched to Kindle application after Amazon bricked my Kindle3 3G reader with a software update (and all other devices worldwide). Now I just wait until Google Books allow to import my Kindle library, and I will never go back to Kindle. Greedy loses twice.
