Little bits and pieces I've done over the years


Many years ago I spent a lot of time creating my Andy Whittaker website because I am a firm believer in sharing what l know and discovered. I am a big fan of open-source software, especially github and even publish some of my own stuff too. Want to have a look at some of the components and software I sell?

Recently, I have also been interested in looking after our planet by focusing my thoughts on renewables and reducing the amount of energy I use. I have built my own house that is fully insulated (cavity filled with 100mm of PU Foam), 4kW of solar PV, ~2200W of Solar Hot Water and (currently) ~23kWh of battery storage. I’m planning to write a few articles in the coming months to share what I’ve done. I will probably author a few YouTube videos while I’m at it.

PylonTech have slightly changed the pinouts of their Inverter CAN connection. Although the CAN connections are still in the same place, there are some extra DO NOT TOUCH connections. Since the LUX Inverter is supplied with a already made-up communications cable with all the pins connected, there are additional RS485 connections that interfere with the communication link.



I’ve always been interested in electronics and then with computer bits added on. From the age 17 I got interested in the oily bits on cars too. Now I have got all environmental and drive an electric car but what a beast it is! My day-job is for a large chemical company designing Instrument Control Systems.

The purpose of most of my projects nowadays is to become more efficient and spend less money in the long-term (and hopefully be less of a burden on the plant). One such example is that I have installed a large, on-grid battery system. This is to time-shift the cheap rate night-time tariff to be used during the expensive daytime period. Whenever I have spare cash, I buy extra batteries and increase the capacity of the system, thereby drastically reducing my daytime electricity kWh unit rate. Although the total cost can be seen as high, I think the return on investment is much higher than that can be achieved in a bank; additionally the savings become even greater when energy prices start to inevitably rise.

I hope you like this. If you have ever wanted to connect to PCs or any two pieces of communications equipment together, it's easy to get confused about what connection goes where. By the previous sentence, I'm assuming you're like me, i.e. why buy a cable when you can...

A Police Lotus EspritOne of my friends sent me this photograph.   I believe this picture is courtesy of Chris Ward. It was found at http://web.ukonline.co.uk/steve.warren/frames.htm - whether it's still there, I don't know. I wonder if it's true? Probably not.......

This was done for a client cira 1998. My customer had a long pipe where at one end four transducers were pulsed with a user definable waveform and, at the other end, there were another four transducers that listened to the resulting sound pulse. The project required a...
