A networked 1-wire controller

Similar projects worth following
TeensyNet V14.0 uses a Teensy3.1 board to monitor / control up to 36 1-wire devices such as digital thermometers, digital switches, K-type thermocouples, the TeensGLCD etc. Multiple TeensyNet boards can in turn be monitored / controlled via UDP over your intranet. The various boards are available from OSHPark, SEEEDStudios, Dirt Cheap Boards, etc and the software is available from my github repository. More information is available at my website.

Take a look at some of the companion boards I've created for the TeensyNet as well.

The TeensyNet started as a way to monitor and control several fermentation chambers and beer storage coolers that I have scattered throughout my home. I wanted something that could be used either stand-alone, or controlled over a wired and / or wireless network.

Using a Teensy3.1 mini-board and a WIZnet WIZ820io board, I can now do just that. For wireless, I use TP-Link TLWR702n and TL-WR703n wireless client adapters.

I also have a complete Linux environment setup on a Raspberry Pi that can find, interrogate and control all of the TeensyNets on my intranet via a LAMP setup and UDP.

    10-18-2014 - I've created version 14 of the TeensyNet Board. I've added the ability to use one of the Serial Ports of the Teensy3.1 as an external debug monitor using a USB-to-TTL RS232 cable. The second I2C line has been brought out to terminalblocks using 3v3 to 5V level converters. I've also added activity LEDs and test points.

Hi Jimmy, I just wanted to let you know that you're doing great, but you need a few more details before you can move on to the next phase of The Hackaday Prize.

By August 20th you must have the following:
- A video. It should be less than 2 minutes long describing your project. Put it on YouTube (or Youku), and add a link to it on your project page. This is done by editing your project (edit link is at the top of your project page) and adding it as an "External Link"
- At least 4 Project Logs
- A system design document
- Links to code repositories, and remember to mention any licenses or permissions needed for your project. For example, if you are using software libraries you need to document that information.

You should also try to highlight how your project is 'Connected' and 'Open' in the details and video.

There are a couple of tutorial video's with more info here:

Good luck!

The TL-WR702n is very easy to setup. I have instructions on setting up both on my webpage.

Do those TP-Link routers make it easy to stick an Ethernet device on WiFi? TI has a new Launchpad with Ethernet, and it would be cheaper to get one of those than the WiFi Boosterpack...

  Are you sure? yes | no
