Project Instructions Please browse our library of "AT HOME" projects featuring full color, step-by-step application instructions. Snow, Ice, water and deicing chemicals can wreak havoc on unprotected concrete and masonry surfaces. Throughout the winter months, water penetrates and saturates unprotected concrete and surface cracks. A few simple and inexpensive preventative measures can help you avoid winter damage and costly concrete repairs. Cracks in Concrete: Water flows through cracks in concrete and saturates the base material. Bufferbloat I received the following question today from Ralph Droms. I include an edited version of my response to Ralph. On Thu, Jun 20, 2013 at 9:45 AM, Ralph Droms (rdroms) <rdroms@yyy.zzz> wrote: Someone suggested to me that bufferbloat might even be worse in switches/bridges than in routers. True fact? If so, can you point me at any published supporting data?

tlc5947 with tlc5940 library - daisy, but.. I didn't expect the distance <30 cm to be of issue, but at the same time I'm not sure what I based that expectation on.. I don't have a camera at hand now, but will try and send some images soon - the setup is very basic - 8 plain breakout boards with TLC5947's connected by 150mm FFC cable, no further components apart from one plain LED per board to test. Arduino Mini Pro or Duemilanove. With shielded cable, do you think 50cm (*16 TLC's) would be somehow achievable? I have no idea what kind of shielding this would require, do you have a direction to look in?

Cerowrt CeroWrt is a project built on the OpenWrt firmware to resolve the endemic problems of bufferbloat in home networking today, and to push forward the state of the art of edge networks and routers. Projects include proper IPv6 support, tighter integration with DNSSEC, and most importantly, reducing bufferbloat in both the wired and wireless components of the stack. The CeroWrt 3.10 series of builds include the following features and capabilities:

Aquaponics – Online Temperature and Humidity This project is a part of the Arduino Data Acquisition and Control System described in the upcoming book Automating Aquaponics with Arduino. You can see a live version of this tutorial here: While this project is designed with aquaponics in mind, it does not require an aquaponic system, making it useful for other projects such as home automation. The included application is, therefore, bare-bones, making it easier to integrate into any other App Engine project.
