There are various James Bond wannabe things on the market these days. Mostly from China.
One of them is a spy pen. A thick, functional metal pen with a built-in video camera. Put it in your pocket, press a button, and order a shaken-not-stirred martini. It's not expensive, too; around $50-$70 will fetch you a 2 gigabyte model.
This particular model was bought in Prague, Czech Republic, in a GM Electronics branch. Its manual comes in English and Chinese, the pen itself lacks manufacturer mark except a tiny label on the white plastic plug on the USB connector side saying "Golden Land hd Video".
The pen can be unscrewed in half. Inside it there is an USB connector. When connected to the computer, the device acts as an USB Mass Storage device, formatted with FAT32 filesystem and USB ID 115e:0003. The disk has no partition table; it behaves like a USB Floppy. The recorded videos are stored in a subdirectory CAMERA_RECORD, with file names like RECORD000001.AVI, numbered sequentially. The pen remembers the sequence numbers even when files are erased from the memory.
The files are AVI files. The audio encoding is PCM, 8000 Hz, 16 bits; lousy but adequate-ish for speech. The video is color, in resolution of 352x288, in H.263 encoding, 12 frames/sec, about 1423 kbps. The video is playable by VLC in Windows and VLC or MPlayer in Linux with no issues.
The device is compatible with Windows. It however has some issues with Linux.
The device contains two crystals; one 12.000 MHz, one unmarked, assuming 32.768 kHz.
Create a file named "SystemTime.txt", with a single line in format
e.g. 2009-10-05 04:30:00
Then save it to the root directory of the spy pen.
When connected to the computer, the pen takes about 10 seconds to be registered by the kernel (Linux 2.4.21). When connected to USB2.0 connector, the operation is highly unreliable; USB packets are getting lost, the device often timeouts and then appears like disconnected. File transfers are next to impossible. When connected to an USB1.1 port, through a hub, the operation was slow but fairly reliable. Copying files both to and from the pen then worked fairly well. Other configurations weren't tried.
The heart of the pen is a board with electronics, 15x70 millimeters, with an attached USB A connector. The system battery is a single 220 mAh Li-polymer cell, with its own integrated protection circuitry.
The pen was disassembled by gently knocking the board out with a hammer aimed at the USB connector. The board is held in position by a plastic ring 4-5mm thick between the USB connector and the pen housing. The battery leads were torn during the disassembly, however their reattachment was fairly easy.
The scale grid, wherever shown, is 5x5 mm.
