Hello Martin,
Is there an introduce yourself topic on here? I haven't seen one, and if there is, is it a sticky so its easy to find? If there isn't, should we start one?
I'm Brent Stevens, AKA Ecobion, and I must say that watching your progress to date has been very interesting indeed. I'm based in Farnborough, Hampshire, in the UK, home to the Farnborough Air Show, and home to a lot of secret technology research & development, defense and aerospace by the likes of companies such as BAE systems and Qinetiq, there's also companies like Motorola, IBM and Nokia based here. Farnborough is also home to the UK Air Accidents Investigation unit of the Ministry of Transport, and is the place where the first airoplane flew in the UK, just 2 years after the wright brothers (and unlike the wright brothers, it flew entirely under its own engine power, rather than slung from a ramp).
I'm into electronics engineering and regular engineering as well. I'm following a few different electronics engineering channels on You Tube, and yours is the latest I've come across (thank Dave Jones for the traffic to your site). Its informative, and you have a positive way of presenting. Nothing worse than presenters mumbling and you can't understand what they are saying.
Lived in South Africa between 1981 and 1985, in Gordon's bay, next to Somerset West, I can't imagine how the country must have changed since I was there.

UFFFF, Is the verification necessary for making posts? Does it eventually go?
