  • A Credit Card Sized Ethernet Arduino Compatable Controller Board

    Sorry for replying to a 6 year old comment :) But this is so niche.. You're a person after my own heart. I have been thinking about designing the board for a "Arduino Nano" equivalent with W5100 / W5500, ditching the USB interface thus saving space, and using QFP packages where possible. I've been looking at the Silvertel for a few years but never bought one or tested it. I found them a while ago around £7 each. This, to me, would be the ultimate little board, a good number of IO pins, and PoE networking. Great for embedded sensors / actuators around the home.

  • Working With the Funduino W5100 Ethernet Module.

    I previously decided on W5100 because it's fully supported by Arduino Ethernet library, and I have some projects that use libraries that depend on this library. I couldn't work out from a quick google whether the W5500 is fully supported under the Arduino Ethernet library or not. i.e. I'm lazy, I know it works well, and there is plenty of good resources online tying Arduino with W5100 which I can rely on when troubleshooting. (Such as this great article!)Having just googled about the improvements of the W5500 over the W5100, Wiznet wrote a few years ago:"W5500 is more cheap, better performance and have 8 sockets"also "W5100 is in Arduino official ethernet shield and we don’t have plan to discontinue."Perhaps given I'm going to the trouble of designing a new boa...

Thanks for bringing that up. See here for a link to my main project that uses the "red board": http://www.automatedhome.co.uk/hardware/video-mqtt-smart-home-wall-controller-code-published.html

    Excellent Instructable. I have used these Funduino boards quite a lot (I call them "the red board") and I do recall having an issue with reset 3 or 4 years ago when I started out with this, which I got over by setting a delay in my sketches. Haven't had a problem since, probably because I just copy from one sketch to another the basics.Similarly I hadn't given much thought to sharing SPI because I've always used the Arduino Mega and can switch other devices to other pins, as there are so many.But now I'm in the process of thinking about making my own Arduino PoE Ethernet board based on ATmega328, W5100 and a Silvertel AG8012s POE module, and I'm SO glad I came across this comment about the SPI bus, as I just hadn't thought about it.I'm nervous about making my own board, as I'v...

    Tales From the Chip: LM1875 Audio Amplifier

    This really whets the appetite! I've bought a couple of amps based on these chips on ebay, but this inspires me to embed them into my own hardware and projects. Basically- audio integrated into the home!

    Automated Light Switch Controller

    Give it a display, add a nice screwless metal faceplate, upgrade the buttons, and voila: https://www.youtube.com/watch?v=HE-3FGcSKfI
