Wow! I want. I want!

This is odd.

This tiny Bluetooth chip doesn’t need a battery because it harvests energy from the air

The Verge – By: Jon Porter – “The Internet of Things promises to connect billions of otherwise ordinary devices to the internet, but when each one needs to have its own battery, there’s a limit to how small or cheap they can become. A new paper-thin Bluetooth chip that’s able to operate entirely without a battery could be about to solve this problem. The postage stamp-sized chip from Wiliot is able to harvest energy from the ambient radio frequencies around us, such as Wi-Fi, Bluetooth, and cellular signals, and use them to power a Bluetooth-equipped ARM processor that can be connected to a variety of sensors.

Wiliot says that the size of the Bluetooth chip, combined with the lack of any battery, means it can be produced cheaply and mounted on almost anything. The company gives several potential use cases for the technology. For example, it could be embedded in consumer products to provide easy access to a digital manual when the original paper version is long lost, or it could be put on a clothing label and used to communicate the optimal settings to a washing machine.

However, the fact that it can also be combined with sensors raises more interesting possibilities. In addition to tracking items through a supply chain, a temperature sensor could also report when items get either too hot or too cold. Elsewhere, a pressure sensor could detect when a food container is empty and automatically order a replacement, thereby making so-called smart fridges truly smart.

Although a recent $30 million financing round means that Wiliot now counts on both Amazon and Samsung as investors, it will still be another year before its sensor tags are widely available. Wiliot says that it hopes to offer them as part of a limited release in 2019 before making then widely available in 2020.”

… was lame. Sorry, but it was. I didn’t see anything there, in all the reports I saw, that looked interesting. In fact, even Stephen Colbert wasn’t impressed, here’s his review:

As you know, I am always looking for technical improvements for the netcast. This year, I am concentrating on the audio! So, after MUCH research, I have chosen the Rode NT-1 Microphone with the AI-1 pre-amp!

The NT1 is a revolutionary new 1″ diaphragm condenser microphone from RØDE.

Although the body of the new NT1 closely resembles the NT1-A, the microphone has been completely redesigned from the ground up, with the only shared component being the mesh grille.

RØDE’s design engineers approached the NT1 as a marriage of innovation and tradition, starting with the capsule which is a completely new design. Codenamed the HF6, it is the perfect example of RØDE’s fusion of artistic design approaches and cutting-edge manufacturing techniques, and features a sound signature reminiscent of the famous microphones of old while at the same time exhibiting extremely low noise.

It has been developed with a focus on detailed midrange response, coupled with silky smooth high frequencies, and warm, round, bass reproduction to make the NT1 an absolute standout in its class.

In another world-first for RØDE, the transducer itself is suspended inside the microphone using Rycote’s industry-leading Lyre system, minimizing external vibrations at the capsule level. The capsule is then married to high-grade electronics that have been designed to provide the lowest noise level of any studio microphone available. The NT1 is an incredibly quiet microphone, measuring only 4.5dBA of self-noise.

Its body is machined from 6061 aluminium and then nickel plated for resistance against corrosion. Finally it is coated in a durable, military-grade ceramic layer, using advanced electrostatic application techniques developed by RØDE to ensure an extremely hard wearing finish that is resistant to scratches or marks.

The NT1 is supplied with the revolutionary new RØDE SMR shock mount. Featuring a unique double-Lyre suspension system, the SMR enhances the existing superior vibration cancellation of Rycote’s Lyre system by using a smaller inner Lyre to act as a tensioning element. This maintains each Lyre in the neutral position where it is most efficient at cancelling vibration. The SMR’s removable all-metal pop filter is as effective as it is visually striking, providing an integrated solution for plosive protection that is easily washable and designed to last as long as the shock mount and microphone.

The NT1 is designed and made in Australia, and is covered by RØDE’s industry-leading 10 year warranty.

Here is a review by audio geek, Bandrew, on his “Podcastage” show:

I will have it in soon! I am jazzed! (Oh, and of course, I didn’t pay anywhere near full price!)

Check out this foldable phone! I don’t see any hinges. I am not sure exactly how they are doing this… but, I like it!
