Hi Toolmaker51

I am open to discussion and of course a nice good debate that we can compare and broaden our skills. Knowledge can never be taken away and I love passing on what I know learning what I don't and of course help me when I am wrong.

We use 220V and 380V in country "ZA" but I am also a electronic design engineer which I designed Air Traffic control systems, toll gates, nurse call, radio comms and a few others. I have recently restarted that skill and found some nice already designed PLC units being Arduino and Rasberry Pie. My current project is access control for an Airport and a Hotel, and have recently been requested to do this for schools. It has been quite a challenge since I have not work to component level in more that 15 years.

Well let me sign off before I write a novel lol

Cheers
Kevin
