The Philbrick Archive - Bob Pease and The OpAmp

The first commercial Operational amplifier was the K2-W op-amp. It was based on the amplifier used in the Philbrick modular Analog-Computor "black boxes ".

First Opamp K2-W op-amp

That amplifier's basic circuit architecture, in turn, was probably inspired by an earlier amplifier designed by Loebe Julie (Dan Sheingold and Bob Pease, thanks for helping me with this information). The K2-W Operational Amplifier entered the commercial market in 1952.

Designing a Tricorder BoosterPack

"The combination of affordable electronics design tools (e.g. Mouser's MultiSIM Blue), open source software licensing, desktop manufacturing equipment (e.g. 3D printers and CNC machines, and PCB manufacturing services (e.g. PCB Assembly Express) that cater to small volume productions are making the niche product design affordable and easier than ever before."

Analyzing the Possibilities: Designing a Tricorder BoosterPack

In the world of Star Trek, Captain Kirk and crew have access to an incredible assortment of 23rd century technology to help them on their missions. The Communicator, the Phaser, and of course, the Tricorder. For the uninitiated, the Tricorder is jack-of-all-trades device that allows a crew member to scan their surroundings to acquire information on just about every environmental variable possible.
