Hackster.io is running a challenge to add voice control to an internet of things (IoT) project, with support from Raspberry Pi and Amazon Alexa.
Bluetooth beacon turns IoT node into a weather station
For IoT sensor nodes read open-source beacons; to finance a product launch go to a crowd-funding website. Finnish firm Ruuvi Innovations is the latest in a rush of developers to use crowd-finding to get their IoT beacon to market in time for mass take-up. Called, RuuviTag it is a stand-alone Bluetooth 5 ready sensor beacon …
Magnetic speed sensor rejects offsets
Allegro MicroSystems’ surface-mount magnetic speed sensor contains a compensating circuit that reduces the detrimental effects of magnet and system offsets. “Digital processing of the analogue signal provides zero-speed performance independent of air gap as well as dynamic adaptation of device performance to the typical operating conditions found in automotive applications, including reduced vibration sensitivity,” said the …

Google Project Bloks for Kids picks Raspberry Pi Zero
Welcome Project Bloks, from Google. Helping kids to get to grips with technology, via modular building blocks, is a crowded space, but that hasn’t stopped Google entering the educational arena.
Gaggione invents a light input structure
Another one that has been around for a while, but I missed it – get in touch folks. Gaggione has reversed the shape of its collimator input cone to reduce stray light. It is implemented in its LLC66x7 silicone collimator range – presumably the optics would not come out of the mould if they were …
NTT uses reflected lasers for encryption
According to the Nikkei, NTT is using reflected laser light for encryption. Random number sequences used in cryptographic systems are usually generated from mathematical formulae but by understanding the algorithms behind the formulae hackers can crack the encryption. Using irregular physical phenomena to generate random numbers can achieve a higher level of unpredictability. NTT has …
Ed Warns Vlad
Ed Snowden really is a bit of a boy – after pissing off the US government by revealing the extent of its surveillance he now risks pissing off the Russkies by criticising a new Bill. The Bill, passed by the Duma but not yet signed by Vlad, provides that: Telecoms companies must keep copies of …
Europe goes for IoT network technology without UK
LoRa, which is bidding to be an IoT wide-area wireless network technology, is being adopted across Europe, but not yet in the UK. Gothenburg in Sweden is the latest city to see a deployment of LoRa wireless network technology as part of a smart city project. This follows announcements of LoRA deployments in France and …
