I have earlier posted DC to AC inverter teardown that showed wat was inside one cheap “modified sinewave” inverter. Now I do a tear-down to a more expensive “true sineware” inverter PI150S from Velleman. This inverter convers 12V DC to nice sinewave 230V 50Hz AC power (up to 150W). View to front and back.

https://blog.hackster.io/launching-open-hardware-satellites-93813a1fe842 Created almost twenty years ago the CubeSat standard has lowered the barrier to entry to the point where you can put your own satellite into orbit for not much more than the price of a high end car. The 10 cm × 10 cm × 10 cm cubes have become so common that you can buy →
http://blog.alexellis.io/live-stream-with-docker/ In this guide tells how to set up our Raspberry Pi so that we can stream live video to YouTube to either a public, unlisted or private stream. Using a pre-built Docker image means we know exactly what we’re getting and instead of having to go through lots of manual steps we can type →
http://www.popsci.com/radio-wave-shield-space-weather?src=SOC&dom=fb This is interesting if true. This is not the first I have heard EM signals from earth affecting ionosphere. When the Navy wants to send a message to an underwater submarine, it sometimes uses very low frequency (VLF) radio waves. Some end up in space and according to a new report, they may be forming a →
https://www.hackster.io/robin-cole/pi-camera-doorbell-with-notifications-408d3d?ref=channel&ref_id=425_published___&offset=3 This looks like a very interesting IoT project. Use the cheap and cheerful Pi Zero W, a camera and an RF doorbell to see who’s at your door! →
https://blog.hackster.io/sifive-unveils-the-first-risc-v-based-arduino-a4d07fe7f21f “Arduino Cinque” is based on SiFive’s Freedom E310 — the industry’s first commercially available RISC-V core — running at 320MHz. Aside from the SoC, an onboard ESP32 chip provides support for 2.4GHz Wi-Fi and Bluetooth. →

The push of government-mandated energy reductions is one factor. It is easier, he noted to meet regulatory standards if you can control the light bulb itself. Shutting down lights when rooms (or even sidewalks) are empty or remotely via phone →

Radar, LIDAR, and camera vision integration are becoming more affordable in modern automobiles. →
http://iotsummit.fi/ Arrow Electronics today organized a IoT Summit event focusing on the Internet in Helsinki. According to Andrew Bickley, who is responsible for marketing the company’s IoT solutions in Europe, IoT is moving from management speeches to implementation. And usually, customers need ready-made solutions. – companies that develop IoT-based services that do not understand the →
https://simplesecurity.sensedeep.com/web-developer-security-checklist-f2e4f43c9c56 Developing secure, robust web applications in the cloud is hard, very hard. If you think it is easy, you are either a higher form of life or you have a painful awakening ahead of you. Think twice before you launch your “proto-product”. Acknowledge that you are skipping many of critical security issues. At the very minimum, be honest with →
