I needed a Console Cable for my Cisco units so I decided to make one.
I created this Cheat Sheet to help me keep my head straight.
Because I never liked crimping cables in my ccna class, i just wanted to use a regular ethernet cable.
This worked out perfectly! I soldered the emulated 568A cable to a DB-9 connector with "L" bent leads (which made it easier IMHO).
I will share images of the finished cable connected to an TTL-to-USB adapter which worked well through the magic of libusb.
I don't know if this chart will be of any use to others but I decided to share it anyways. Hope it helps.
This was pulled from a 3com fast Ethernet card which was being discarded as e-waste by my university last year.
On the right, midway down the chip the broadcom logo is inscribed as well as "TORNADO", "BCM5904", "REV A0444" and "1998". There are several other letters and symbols around the die, but I cannot determine their significance if any.
The only documentation I could find about this exact chip was this: www.sec.gov/Archives/edgar/data/1054374/0000892569-99-000...
If you search "BCM5904" in that document it describes it as:
"Single chip 10/100Base-T transceiver with integrated MAC ASIC."
This is a composite of 42 images taken by a pixel 2XL from a microscope at 40X. The images had 65% overlap and were stitched together in AutopanoGiga.

I got my Adafruit VC0706 serial camera working, and hacked the SD example to produce base64 HTML compatible output instead. This way you can use your camera with an Ethernet shield or even use a computer to link the serial port to an http port on the network and use the camera as a netcam.
The camera doesn't see our world the way we do. It can see color, but it has no IR filter, so the near IR light skews the colors it tries to represent. This is great for night vision, but dreadful for color fidelity.
Note the terrycloth bathrobe to the left, to human eyes it is very black. But in near IR apparently it is a very bright shade of infrared. The camera doesn't separate out the IR, so it gets counted as R G and B and that's why the black robe seems grey instead of some one color or another.
Here's the hacked example. I release my content as public domain. I believe the adafruit code is also public domain.
Be warned, Flickr isn't exactly C/C++ friendly. so some of the symbols may be mangled (especially if they remotely resemble HTML tags, like <= 100

This is a Broadcom BCM5708 Ethernet controller. The server this was pulled from had two identical chips like this, so I only had to open one of them.
It appears to have been designed in 2006 and it uses 4X pcie lanes which you can see on the bottom right (light green blocks).
Here is the best documentation I could find: www.digchip.com/datasheets/parts/datasheet/072/BCM5708-pd...
This server was given to me by a friend and has enough chips to keep me busy for a while :)

Pfc. Sadie Eversole, a Pomona, Kan. Native, assigned to 579th Signal Company, 70th Brigade Support Battalion, 210th Field Artillery Brigade, 2nd Infantry Division/ROK-US Combined Division, rolls up an ethernet cable as the unit prepares to relocate during a field training exercise at LTA130, South Korea, May 3, 2017. The movement of a TOC (jump TOC) provides Soldiers training on how to quickly and efficiently move equipment and personnel to another location with minimal notice. –Thunder! (U.S. Army photos by Cpl. Michelle U. Blesam, 210th FA Bde PAO)
Before I assembled this computer (Sept '05), I masked off and shot the interior in flat black. I take extra special care when routing the cables to ensure the best possible airflow and appearance.
There are only five LEDs visible in or on the case. One in the powersupply, a status light on the mobo, the HDD and CD access lights, and the power indicator.
I don't like a lot of flash.
Next up: Get rid of that ancient motherboard. (it only takes DDR400) Which buys me into getting a new Mobo, Processor, and RAM. Might as well get a new case too.
The same Wiznet chipset as the forthcoming Arduino Ethernet, but in the form of a shield that attaches to an existing Arduino.
It took me about five minutes to get a simple HTTP request going using the ethernet software library.
The SD memory slot is reserved for future use. There's no hardware FAT32 filesystem driver, so it's only usable for direct block access right now.
Allwinner H3, 40x40mm, 512MB DDR3 RAM, 2xUSB, 100Mbps Ethernet. The packaging was wet for some reason.

To enable development with the LAN9353/4/5 Three-Port 10/100 Ethernet Switches, three Microchip evaluation boards were also added that support various system architectures. These hardware systems demonstrate how to interface with the switches through basic input/output connections, or with microcontrollers such as the 32-bit PIC32MX family via serial communications.
Each of these new evaluation boards is also supported by a Software Development Kit (SDK), which enables developers to immediately start device evaluation, familiarize themselves with features, and begin building solutions for their applications. All three evaluation boards, (part # EVB-LAN9353, $300), (part # EVB-LAN9354, $250) and (part # EVB-LAN9355 $300) are available now via any Microchip sales representative or authorized worldwide distributor, or from microchipDIRECT (www.microchipdirect.com).

The Arduino Ethernet Shield 2 allows an Arduino board to connect to the Internet. It is based on the Wiznet W5100 ethernet chip providing a network (IP) stack capable of both TCP and UDP. The Arduino Ethernet Shield 2 supports up to four simultaneous socket connections. Use the Ethernet library to write sketches which connect to the internet using the shield.
The ethernet shield connects to an Arduino board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top..
The latest revision of the shield adds a micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Duemilanove and Mega (using the Ethernet library coming in Arduino 0019). An SD card library is not yet included in the standard Arduino distribution, but the sdfatlib by Bill Greiman works well. See this tutorial from Adafruit Industries for instructions (thanks Limor!).
The latest revision of the shield also includes a reset controller, to ensure that the W5100 Ethernet module is properly reset on power-up. Previous revisions of the shield were not compatible with the Mega and need to be manually reset after power-up. The original revision of the shield contained a full-size SD card slot; this is not supported.
Arduino communicates with both the W5100 and SD card using the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on the Duemilanove and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W5100 and pin 4 for the SD card. These pins cannot be used for general i/o. On the Mega, the hardware SS pin, 53, is not used to select either the W5100 or the SD card, but it must be kept as an output or the SPI interface won’t work.
Note that because the W5100 and SD card share the SPI bus, only one can be active at a time. If you are using both peripherals in your program, this should be taken care of by the corresponding libraries. If you’re not using one of the peripherals in your program, however, you’ll need to explicitly deselect it. To do this with the SD card, set pin 4 as an output and write a high to it. For the W5100, set digital pin 10 as a high output.
The shield provides a standard RJ45 ethernet jack.
The reset button on the shield resets both the W5100 and the Arduino board.
Available soon!
