Moved to New Zealand

  We are still in the process of getting our production fully established in New Zealand. We are now using boxes made in the UK and PCB's made locally. New products are planned to be released in the first few months of 2010 and the first of these is a FLEXI-BOX with a PCB prepared with photo resist. Two smaller FLEXI-BOX versions are in the process of being manufactured in New Zealand and will be released as soon as they are available.  

Website

   The website style has  been brought up to date with smaller navigation bars at the top of the page and a greater use of headers. 

     The whole website is currently optimised for Internet Explorer 6.0, Mozilla Firefox 2.0.0.20 and Opera 10.10 browsers.

Sales

   We have re-started e-commerce sales now that we have re-located to New Zealand and will soon be fully operational. Delivery periods are well reduced and will soon be reduced again. Our sales follow the increase in popularity of the website and we are expecting the new products planed for the next few months to improve them even further.

New Calculators

  The latest addition to this section is added for those who find interest in the mathematics used in our calculators, the Elliptical Integrals of the First Kind Calculator follows our usual model and gives equations as well as answers.

There is also the new Calculator for the Inductance of a Flat Wire and this can evidently also be used for PCB tracks.

  A calculator has also been added for a  rectangular parallel plate capacitor. It includes edge effect using one of my own formulas. If you use it please give some feedback as to it's accuracy. It works fine for me but is unproven by anybody else. Also, if there is another calculator that you would like to see added please Contact Us and we will do our best to include it.

 On the subject of capacitors; it is obvious from the formula derived that there is an electric field from all of the outside of the parallel plates of the capacitor. This can be seen in the edge effect value being proportional to the total plate area, not the perimeter. This proves to me the existence of the electric field over all of the outside of the plates but I am unable to locate a reliable proof of this on the Internet or in books. If you happen to know of one, please let me know.
