A mechanical engineering researcher has developed silicon dioxide nanoparticles (or ‘engineered sand’) coated with a high dielectric constant polymer to provide an inexpensive solution for cooling electronics. Fortunately, whether you’re shopping for family or friends, adults, kids — even pets — Best Buy makes it easy to discover tech gifts that will spark your imagination, get you in the spirit of giving and make this holiday extra special. Ordinary electronics gadgets, unless specifically for lab use or other environmental constraints, will have been designed to run at 45C ambient. This was not, as I once supposed, due to the manufacturer’s time bomb design” forcing me to buy a new computer. Here are some of the more interesting and cool digital car gadgets and accessories I have dug up in my web electronics

The Electronics Associate Digital (EM4) certification is an entry-level credential designed for technicians in the electricity and electronics field. Curtiss-Wright in the next year may introduce new electronics enclosures with special cooling built in to enable designers to use today’s high-power computing modules without modification in embedded systems. Consider additional test gear after you’ve gained some experience in electronics and want to graduate to bigger and better electronics

RADAR Electronics Technicians must be knowledgeable and have abilities in the following technical and human relations areas: Block Diagrams and Schematics, Components, Cabling and Antennas, Hand Tools & Soldering, Mathematics, Amplifiers, RADAR Transceivers, Interfacing, Satellite, Wireless, and Data Communications, Computers and Digital Concepts, Software Programming, Troubleshooting, and People Relations.

I think these days more and more people are looking for electronics online rather than in actual stores, so it’s good to be cautious and shop around to get the best deal. That’s right – Make: Electronics is available in digital format for only $10 (no shipping costs!) – if you’ve been considering purchasing a digital copy or know someone who’s shown an interest in the book, this is a good price. Wonderful things can come in small packages, including cool gadgets that fit perfectly in holiday electronics

The GE Thermal Ground Plane approach combines evaporative cooling and capillary action to cool extremely hot electronics. This approach is relatively inexpensive, but can threaten the reliability of deployed military electronics. Candidates must hold the Associate Certified Electronics Technician (CETa) certification prior to taking the Avionics Electronics Technician exam.
