While the stench of rotting food would cause you to stop from chowing down, chances are it became unfit for consumption some time before those funky aromas wafted through your nostrils. Chemists at MIT have been working on a wireless, inexpensive sensor that, among other things, identifies spoiled food early by detecting gases in the air. It then shares its data with a smartphone, potentially alerting users to that soon-to-be moldy fruit in the bottom of the fridge.

The Bluetooth Special Interest Group (SIG) has published the specs for the next generation of Bluetooth devices. Bluetooth 4.2 has a few improvements that will be of particular interest to developers of IoT devices. The biggest change is support for an Internet Protocol Support Profile (IPSP) which enables IPv6 for Bluetooth. This means that wearable or IoT devices (based on Bluetooth Low Energy) will not need to be paired with a smartphone or tablet to gain access to the cloud, they will have access to the internet via a Bluetooth/WiFi enabled router.

HRL Laboratories, based in Malibu, CA, recently tested a prototype neuromorphic chip with 576 silicon neurons aboard a tiny drone measuring 6×6×1.5 inches and weighing 93 grams. The project was funded by the Defense Advanced Research Projects Agency (DARPA).
The drone, custom built for the test by AeroVironment of Monrovia, CA, flew between three separate rooms. The aircraft was able to process data from its optical, ultrasound, and infrared sensors and recognize when it was in a new or familiar room.

Someday soon, your milk carton may be able to tell you that the milk has spoiled, or your bandage may indicate that it needs changing. These and other things could be made possible by a new technique developed at Singapore’s Nanyang Technological University, which allows disposable electronics to be printed on a variety of surfaces, using an existing T-shirt printer.

Intel announced its 4004 processor and its chipset through an ad in Electronic News on November 15, 1971, making them the first complete CPU on one chip and the first commercially available microprocessor.
The building-block 4004 CPU held 2300 transistors. The microprocessor, the size of a little fingernail, delivered the same computing power as the first electronic computer built in 1946, which, in contrast, filled a room. Full technical details for the 4004 can be found in this January 1972 EDN story on the technology: One-Chip CPU available for low-cost dedicated computers.

In a serious case of out-of-the-box thinking, a design team at Roost in Sunnyvale California have come up with a method to add Wi-Fi connectivity to your old smoke or carbon monoxide alarm by just swapping batteries. Your smoke detector uses a 9 V PP3-type battery right? The new Roost battery contains 9 V lithium cells together with a processor and Wi-Fi chip in the standard PP3-sized battery outline. It monitors the battery voltage and power drain to alert you via Wi-Fi and a smartphone app when the alarm has been triggered, even if you are not at home.

As automotive electronics takes center stage at Electronica this week in Munich, a “microcamera” module recently designed by researchers at the Fraunhofer Institute for driver-assistance applications is expected to enjoy the spotlight.
The new camera module — an image sensor with optics mounted on a printed circuit board — measures 16x16x12 cubic millimeters. It is visibly smaller than current-generation driver-assist cameras, whose edge lengths are “20x20x20 cubic millimeters (without optics),” according to a Fraunhofer press release.

The Raspberry Pi Foundation has unveiled the Raspberry Pi A+ – a smaller version of its original Model A – that costs only $20. The Model A+ is significantly smaller than the Model A (65 mm in length versus 86 mm), consumes less power, uses the BCM2835 application processor, and has 256 MB RAM.

Representatives from the Fraunhofer Institute for Photonic Microsystems IPMS in Dresden will be showing off their Li-Fi wireless communication system at the upcoming electronica exhibition held in Munich from November 11 to 14. The system uses infra-red light as the transmission medium and can transfer data at a speed of up to 1 Gigabit per second over a distance of up to 10 meters.

It can be a herculean task to get kids to eat their vegetables, but they’ll happily chow down on things they aren’t supposed to. If one of those things is a button battery, serious injuries can result in the form of burns to the esophagus or tears in the digestive tract. Researchers may not have found a way to stop kids swallowing button batteries, but they have found a way to make such culinary no-nos safer.
