In South Africa the fire protection sprinkler system has a different model to the one used in North America.
The Drone Dilemma, Part 2: Legal
Scott Deuty 1/26/2016 2 comments
There is no doubt that legal subjects intermix with privacy and air space. So the legal subject matter that is referred to herein will focus on drone registration and the development of laws and regulation. Other legal matters such as privacy and air space will be covered separately.
An Isolated Potentiometer, Part 1

The following isolated anapot, or isopot, design is intended as a design “template” for general application wherever a manually-actuated pot is to be replaced and actuated by an analog voltage.
Build a high-voltage linear regulator
Steve Taranovich 1/12/2016 13 comments
Generating a regulated voltage from input rails exceeding 100 V is challenging. A limited selection of integrated solutions complicates the problem. Creating a discrete voltage regulator enables a low-cost solution, but the design process is involved and requires a deeper understanding of key engineering tradeoffs, with an emphasis on device thermal properties.

Google "proved" the D-Wave 2 they operate jointly with NASA (mainly paid for by Google) can operate "up to ∼ 108 times faster".
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
