Stumped for a way to evaluate programmes that purport to find bugs in other software, US researchers have created a programme that adds thousands of bugs to other software. LAVA (Large-scale Automated Vulnerability Addition) is the result, a technique of intentionally adding vulnerabilities to a program’s source code, which has revealed that “many popular bug …
Toshiba opto-couplers have integrated ADC
Toshiba has announced two new digital output isolation amplifiers for current and voltage sensing in power converters. The TLP7830 and TLP7930 achieve high accuracy through the inclusion of a delta sigma analogue-to-digital converter (ADC). Accurately monitoring the phase current of motors and BUS voltage fluctuations is essential when providing feedback to the microcontrollers used in …
Miniature oxygen sensors have four-second response time
The Zirconia Miniature series of oxygen sensors from SST Sensing are five-pin devices with a response time of four seconds covering an oxygen range from 0.1% to 100%. According to the company they can operate in oxygen pressures from 2mbar to 3bar with good accuracy and linearity. Target application areas for the devices are combustion control in …

Fable: The Showman
There was once a founding CEO who had such determination that he is said to have closed two important business deals by staring so hard at the people on the other side of the negotiating table that they broke down and cried. He believed in high living and built a headquarters which resembled a luxury …
2D perovskite offered for solar cell research
US researchers are working on 2D perovskite crystals as a potential material for solar cells. Perovskite-structured materials are causing a stir in the world of solar power conversion, going from just-working to exceeding the efficiency of some conventional materials in only a few years. However, they have some serious drawbacks which are keeping them from …
Educational embedded computer works with Arduino software
Circuit Playground is an Arduino-like education development board from Adafruit, designed around an Atmel ATmega32u4 MPU – as used in the firm’s earlier Flora board. The round 51mm diameter board has 14 croc-clip pads for easy access to power and I/O, with the eight non-power pads doubling-up as capacitive touch sensors. Programming based on the …
Glasgow adds geo-location to LoRa IoT network trial
A consortium has installed a 12km2 LoRa IoT network in Glasgow, covering its commercial centre, Merchant City and West End. “The network will enable the development and use of devices such as building and indoor environmental monitors, pollution sensors, tags for tracking valuable assets and social care devices designed to support independent living,” said the …
