Infinitum Electric’s circuit board stator

Printed Circuit Board Stator

Carl Bujega’s PCB motor
  • 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?

  • The deal was announced last May, worth $1.76 Billion.

Magic Whaaa

A Ferrofluid Clock

  • 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

  • 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.
