Circuit Boards Are Now Motors! Company Acquires Another Company! Oil is the New Data! Ferrofluid Clocks! Magic Leap Sells 6,000 Headsets!
Printed Circuit Board Stator
- Infinitum Electric has created a new type of electric motor: one where the stator is a simple circuit board.
- Electric motors are just coils of wire and magnets, with the most difficult (and heaviest) part of the motor being the coils of wire. If you can put a trace of copper on a circuit board, you can also put a coil of wire on a circuit board. So now we’re here.
- The goal of this project is to build a smaller, lighter electric motor. That means less mass, and less power required to move a car.
- As with all inventions, this is not the first time this has been done. Carl Bujega designed and built a few PCB motors over the last few years, all of them decidedly smaller than the Infinitum motor.
- There are drawbacks to Carl’s motor: it doesn’t really have a lot of power compared to a small brushless motor, because PCB traces can’t handle the current of a comparatively sized piece of wire. Still, progress is progress!
You Down With NXP?
- NXP has finalized their acquisition of Marvell’s WiFi Products Group. The move is expected to add WiFi, Bluetooth, BTLE, Zigbee, Thread, and NFC to the NXP portfolio.
- The deal was announced last May, worth $1.76 Billion.
- Magic Leap has only sold 6000 headsets in six months according to The Information. Magic Leap has received $2.3 Billion in funding from Google and Alibaba.
- The VR/AR startup sells a $2,300 headset that superimposes the virtual world on the physical. The CEO projected they would sell 100,000 headsets in the first year.
- Cool, only 94,000 headsets to go.
A Ferrofluid Clock
- Ferrofluid is small magnetic granules suspended (emulisified?) in a liquid substrate. It makes a great clock, too.
- Fetch is a ferrofluid display from Applied Procrastination that uses 252 electromagnets to build a 12x21 resolution display using ferrofluid as the pixels.
- The biggest challenge is creating a container that allows the ferrofluid to be suspended and not stick to the glass or itself. The best solution so far is suspending ferrofluid in a saturated salt water solution.
Oil is the New Data
- A recent article on Logic Mag about the collaboration between Big Tech and Big Oil might seem counterintuitive. Culturally, who could be further apart?
- For big corp cloud providers, winning the IT spend of the Fortune 500 is where most of the money in the public cloud market will be made.
- Among those Fortune 500, Big Oil sits at the top.
- In other words, the success of Big Oil, and the production of fossil fuels, are key to winning the cloud race.
