Sensors and Transmitters Real World Interface

I just got a letter from a US firm enquiringly about my transmitters. It read something like …

“…..Mini RTD Pt100 Three Wire Transmitter is commercially available? We may be interested in both the 100 ohm RTD input as well as the 1K ohm RTD input types”

I do not respond to product enquiries as i do not “Make” anymore. But, this letter is about a design of mine that is published in my pages. It is a low cost transmitter anybody can build. Study my Elex Quna where some such letters are published. I may now reply only mail that stimulates me, and appears genuine enough. If you are an engineer in the US, try making these, a better way possibly, and serve people using online stores. Online shops should offer Cards, Cheque and Cash-On-Delivery to enable all types of customers. Items in a store must reach clients, inside 7 days. Other products should be cataloged with prices, outside store application.

Small manufacturers have to get their profile and products across. Just building a site is not enough, you need to advertise. People search for solutions, by proper advertising you can get tuned/filtered visitors to your website. These people were looking for solutions and you are looking for customers.

Other “promotional techniques” get you a lot of visitors. Even “ranking high in search results” gets you “Visitors”. This traffic is like Kids looking for Chip-n-Dale landing in a Vertical Niche Product Catalog for Steam Turbines. This will just build bandwidth cost for you, but you will have a nice feeling you are getting Visitors. This may even make your site slow for the rare real visitors, who want to buy your products/services. So think smart, nothing comes easy, lot of hard (straight) work.

I suggest start with Google’s Small Business Network and a nice Blog. Try WordPress or Blogger.

Mechatronics a Montage of All Engineering

I once knew a dogbert, i will not name him. Yet his words resonated as true again and again. Once when someone asked him .. “Where the highest value can be created, in an engineered product?”. He reveled a profound secret, that is only discussed in whispers in the backrooms of high-tech upstarts. I will attempt to phrase it in a more concise manner.

“When the raw materials transform into an Engineered product, the highest engineering value is both in the manufacturing process machinery and the manufactured product; If and only if, that product has mechanical, electrical, electronic and computing elements in its composition.” – This was Mechatronics?

In essence it appeared to be a CNC machine, but not exactly, CNC too and much more. Robotics is a pinnacle of this collage. Then an Intelligent Embedded Control System with sensors, switches, tachos, drives and motor a part of Mechatronics. Looks like control engineering, a sub-section of mechatronics too. Control engineering is also an independent science. Can’t leave out Intelligent machinery and Complex Gadgets.

Without chemical, component and materials engineering all the above cannot materialize. They create the inputs and technologies to the systems above.

Finally two examples for Mechatronic Marvels – One the Lone Martian called Rover (like Wall-E) and the Ultra Busy HardDisk HDD in your own Computer.

Karnaugh Map Minimizer – Refactoring Code

A tool for developers of small digital devices and radio amateurs, for those who is familiar with Boolean algebra and Karnaugh Map optimization method, best suits for electrical engineering students.

Karnaugh Minimizer - Refactoring Code

Karnaugh Minimizer – Refactoring Code

  • Draws 2 – 8 variable Karnaugh Maps
  • Quine Mc Cluskey minimization
  • Convert boolean to VHDL / Verilog
  • Simplifies boolean expressions

“The Karnaugh map was invented by Maurice Karnaugh, a telecommunications engineer at Bell Labs, in 1950., same year that Charles M. Schulz published his first Peanuts comic.”Karnaugh Map Minimizer

This program sports some of the most amazing features in Karnaugh map minimizing sofware known to modern man, like solving up to 8 variable maps, solution highlighting, input form a truth table or directly on the map, displaying cell adresses.

Karnaugh Map Minimizer is free (GPL) software for minimizing boolean functions using the graphic method of Karnaugh maps.
