‘Pacific Rim’ Is An Engineer’s Worst Nightmare

The scale of Pacific Rim is overwhelming. Giant monsters fight giant robots while being slammed with waves that appear to be hundreds of feet high. The combatants trample their way through major cities, while doing things like using an oil tanker as a baseball bat! When you see something like that, your brain tells you two things. First, this is awesome. Second, there’s no way that’s possible.

What follows are the thoughts of a real-life engineer when faced with this information.

Happy Bornday, Nelson Mandela!

95 years strong. A true fighter.

Be sure to check out the upcoming biopic, Mandela: Long Walk to Freedom, starring Idris Elba later on this year (Nov. 29).

A scanning electron microscope image of tiny silicon pillars, used to absorb light. When dotted with a new catalyst and exposed to sunlight, these pillars efficiently generate hydrogen gas from the hydrogen ions liberated by splitting water. Each pillar is approximately two micrometers in diameter.

For around $30 in parts and a good amount of patience, you can have a completely open source and hackable mp3 player ready to go. It can be modified to accept serial commands, be embedded in an art project, used as the voice of your next smart talking robo-sidekick, or filled with music and used as is. Put in whatever size card you want, up to the theoretical limit of the MMC format! All the source and schematics are here for free as part of the Creative Commons. I have kits available if you don’t feel like scavenging for the parts yourself.

The ENC28J60 is a stand-alone Ethernet controller with an industry standard Serial Peripheral Interface (SPI). It is designed to serve as an Ethernet network interface for any controller equipped with SPI. 

The ENC28J60 meets all of the IEEE 802.3 specifications. It incorporates a number of packet filtering schemes to limit incoming packets. It also provides an internal DMA module for fast data throughput and hardware assisted checksum calculation, which is used in various network protocols. Communication with the host controller is implemented via an interrupt pin and the SPI, with clock rates of up to 20 MHz. Two dedicated pins are used for LED link and network activity indication.

Mike Negrete, Design Engineer - Power Products  Isolated power supplies are needed in a wide variety of applications. Galvanic isolation is achieved by isolating two or more circuits using a transformer or optocoupler, and is desirable for many reasons: safety, noise immunity, circuit protection, etc.
