Chris, I am only up the road from you, so unless I sell my car soon you can count me in.

Chris, they are the Trojan T125 6 Volt.

timpootle, any updates on this mammoth project?

the battery warmers in the car only work when the car is plugged in so I can only assume they use the 240 volt supply. Have you considered using an electric blanket at all? This could be wired so that it is on all the time that the car is plugged in, and it could also double up as insulation for the...

the cold weather will hit lead acid batteries the hardest and reduce their capacity by quite alot. I am not sure of off the shelf heater mats, but I know that in my Gwiz the lead acid batteries have got a heaters wrapped around them and this is designed to keep the batteries arounf the 25C mark. I h...

I think that I would love to have something like this for use in my Gwiz. I might have to read the whole forum again and see what it is that I need to get and to do. I do like the idea of a nice gadget like this sat on the dash giving me all sorts of information. Apparently there is one available fo...

What sort of range are you getting with the new batteries in it? Does your conversion still have the gear box in it? as 35mph is pretty slow for a top end speed.

I cant do any better than jeremy i'm afraid. The 16 bit is the limiting factor and the amount of resolution your going to get will be limited by this. You could do a straight bit shift of my original calculations until you have the resolution you want which I think you said was down to 10th's of a m...

Right with these figures lets try some maths. We will have 2 contstants to use. We know that at 1.875 mph the VSS length is 42176 So we know that I can do ( 1.875 / mph ) * 42176 to give me a new VSS lengh So i need to reverse this to use a pulsin reading to give a mph reading. mph = ( 42176 / pulsi...

Just to let you know that I am rambling away to myself to try and work this one out and I am coming up wth some interesting figures - so watch this space.
