Interpolation Tool

So, if you work with any simple data at all, chances are that every now and again you will need to use that data to make predictions. One of the most common ways to do this it to take that data in its graphical form and to draw lines on it that can then be measured and scaled readings taken.

If you want to feel more precise, you may perform some form of interpolation between points of data. This is a simple technique in terms of calculation however, if like me you occasionally find yourself having moments of moronic interludes, what is important to remember is that errors made in this case are not obvious, and the data should be closely checked.

What I have found useful is to produce a tool that sits between the graphical and interpolation techniques. This gives a more natural way of working with data, solves the error issue and actually produces some nice graphics that can be used in reports, emails and other communications.

I have made the video below, and if you think this might be of use to you, the excel sheet is free to download on the following link -Interpolation Tool-

Easy Wireless Electricity Circut

Think your wireless phone charger is hi-tech?

Well it may be, but it was invented nearly 100 years ago! This video is an air-core transformer that is set to resonate and so induce an alternating current wirelessly

This is ont of my favourite projects to demonstrate this prinicple. Its simple and cheap too!!!!

Nikola Tesla's Valvular Conduit

This is a solid state valve, no moving parts invented by Nikola Tesla around 100 years ago! The device isnt a check valve but exhibits far increased turbulence and losses in the reverse direction and so flow in that direction is Harder!

What do you need?

As discussed we have a wide range of expertise and experience, We would love to help you. Realising a prototype, evolving through manufacture to setting up lean and responsive supply chain elements. Product realisation is all part of the service.

We are engineers, and we can help you!

We particularly enjoy the design and production of bespoke and one off pieces. Demonstration pieces for sales or training are a speciality, as are test rigs.
