The cows look interested.
 
The Texas hill country is no stranger to drought. A new network of sensors in this bone-dry region of the Lone Star State will produce detailed data on soil moisture while also verifying measurements from NASA's recently launched Soil Moisture Active Passive (SMAP) observatory. Together, SMAP and the Texas Soil Observation Network (TxSON) will give state water agencies critical information about how soil moisture — or the lack of it — will affect reservoirs, crops and rangeland.

NASA uses the vantage point of space to increase our understanding of our home planet, improve lives, and safeguard our future. NASA develops new ways to observe and study Earth's interconnected natural systems and freely shares this unique knowledge with institutions around the world to gain new insights into how our planet is changing.

I was looking for a 1N34, 1N60, or 1N270 germanium diode and none of the main parts suppliers have any. So after some research substitutes were found. Germanium diodes are rarely made anymore and small signal Schottky are equivalent. Replacement parts are as follows 1N6263, SD101, 1N5711, BAT81, and CDSH270. I am sure there are a few others as well.

I found the original project that the transistor tester (fish8840) was based on. A link to the english version of the documentation is below.

I built up the circuit board for my TDR (Time Domain Reflectometer) project last weekend. The kit was purchased from http://www.farcircuits.net/ and for more information go to http://www.epanorama.net/circuits/tdr.html . I still need to finish the case and mounting of other parts, and wire everything up.
What is a TDR? Watch this video to find out http://youtu.be/9cP6w2odGUc #electronicskit

Blue ESR Meter Kit: I had fun building this this weekend it took me about 9 hours including breaks for pictures to build. It is working great. If you would like to build one you can purchase one at http://shop.anatekcorp.com/products/component-analyzers/blue-esr-kit/?back=products . 73

A virtual testbed for networks. Much better than pulling out or buying hardware. Just make sure you have enough system resources to run all these virtual machines.
 
Non-Linux FOSS: a Virtualized Cisco Infrastructure? - We're all familiar with the idea of virtualized computers. Not only are they a great way to better utilize resources in a server room, but they also allow you to create and destroy servers in the blink of an eye. That's perfect for a lab or training environment. Unfortunately, it's always taken a rack of actual hardware to create a training lab for Cisco hardware. more>> http://ow.ly/2LC1tW

I finished up the TDR kit a few weeks ago. Here are the rest of the photos, sorry that they are blurry the camera does not like the distance.

Also here are a few videos of what this project is for - http://www.youtube.com/playlist?list=PL4auJ7V8HZsxxvpzBOZFYy2BEqD-CUS_l

My current night time reading. I am about half way through and so far interesting. The material is dated but gives insight into the role of how media makes money.
