Well went for a drive to Tailem Bend this morning to renew my membership with the car club and get my merc onto historic rego
Well got told the vehicle MUST be registered to transfer over so put the remaining 2 months on with my mobile and joined the end of the line. So now got the papers to take to Service SA and next meeting get the logbook.
Anyway on the way there got thinking why my seed trials failed and one can put that down it's just too bloody cold for them to grow.
Thinking I did have some old 0.25mm ni-chrome wire when I got home untangled 2 metres and found my DMM's would just show Mega ohm readings. So the real test was just hook it up to my power supply
Well it looks like I made a 60 ohm resistor and with a 12 volt input 200mA current draw and by going lower voltages the relationship did correspond with 60 0hms.
Now with a 200mA current draw the temp is around 34C so this will fit with one of my old N70 batteries for another conversion. Just drain the fluid of the battery use some baking soda to neutralize then put a pool chemical in from the big green shed. Then leave it on my 5 watt array of panels so charge and within a week the battery will hold enough charge for a 200mA draw.
