  • Digital I/O in chunks: distribute control and status
  • @ rciszek Even the PDFs have lost their diagrams. EDN search isn't the best, so I often use Google - but they have little more. I found this [ http://cdn.embedded.com/ContentEETimes/Images/EDN/Design%20Ideas/ ]

  • Control an LM317T with a PWM signal
  • He's done the time so why not? Google will know, now, and thus the whole world. And not all contributors have qualifications - look at the scores of successful hobby inventors.

  • Electronic products from hell
  • Your Monkey article lives on. http://www.designnews.com/content/monkeys-got-my-cardio-machine/1667424933426

  • Hands-on with BLE, apps, and ARMduino: The Simblee
  • My first adventure with Simblee was for a link between my motorscooter and my helmet. The helmet displays (duplicates) turn signals and stop signals through LEDs buried in my helmets. These sure grab car drivers attention.

  • *duino meets chipmakers: What's all this then?
  • I think what is driving a phenomenon such as Arduino's popularity is much as it was in the days of Digital Equipment Corporation - crowd supported resources. Anyone who is familiar with the PDP8, widely considered to be the first successful minicomputer, or it's successor the PDP12 and later the VAX series would likely agree that one of the greatest strengths was the DEC Software Library. Likewise with Arduino, PIC (and it's special version called PICaxe) - there is a wealth of crowd-generated software that makes the first steps so easy. Furthermore, there is gold in these software files, gold that makes the commercial use of the products a breeze, Now that Arduino has settled it's founders personal disputes, they have entered into production agreements with companies in many diverse countries. The famous New York-based Adafruit, along with Sparkfun, have contributed hugely to Arduino's success. Arduino, along with Atmel, made programming a breeze by supplying free software authoring tools. All these techniques have been copied by latecomers. The old time People-helping-People from Hippie times is back in vogue!

  • Solar-array controller needs no multiplier to maximize power
  • EDN search is a little weak. I usually use DuckDuckGo or Google to find the missing parts. Another annoying EDN habit is to say XXXX XXX, Part 1 which implies there is a Part 2, but in reality Part 2 doesn't exist OR they change the title and append Part 2!

  • The skinny on LED strips
  • In Indochina we can buy 5 metre and 100 metre lengths - the latter for building and structure illumination. The longer lengths are supplied with plastic piercing clips through which power is fed at intermediate points. If you are buying over 10 pieces the factories will cut to your specifications. (I live next door to China in VietNam) We can buy various quality grades: the basic, open type; the plastic covered type with heatshrink covers over the end joints and the REAL waterproof types with molded end connectors. The really waterproof types cost, at retail, USD$12/5 metres. A trick to watch out for with cheaper Chinese products, at least cheaper for the importer, is that they use iron stranded conductors that have been copper-coloured! Of course, a magnet will determine what is in the product you are thinking of buying. You even find this in power extension cords.
