Weekly Roundup – Top Links for the 4th Week of September 2017

From the Editor

There is always something going on in the world of electronics, and it can be easy to miss some of the news that comes out. This is the first of a series of weekly posts in which I will gather interesting links from around the web to share with you. If you happen to come across something interesting or if you are a vendor that would like to share something, please drop me a line.

I’d love to get feedback from readers, so if you have a topic that you would like to see covered more, then please let me know. The better I understand the needs of the audience, the better information I can publish.

Lastly, in the coming weeks, we will post some blogs regarding the upcoming holidays of Deepavali and Halloween. In conjunction with Halloween, we will be doing some cross-posting with the magnificent team at EEWeb, headed by the Magnificent Max Maxfield. Here is his first go at fun Halloween creations.

The Pocket measures 56 x 35 x 5 mm.

LimeSDR Mini Successfully Reaches 100% Funding Level

After their first successful crowdfunding effort, Lime Microsystems has returned with a second effort to bring a small, open-source SRD to the market. The LimeSDR Mini sells for $139 and has both transmit and receive capability. Its frequency range is from 10 MHz to 3.5 GHz with a bandwidth of 30.72 MHz. I personally purchased the non-mini version of the LimeSDR and have really enjoyed it. This week, it reached 100% funding and will proceed to manufacturing after the close of the funding campaign.
