Hi,
greetings from Italy !
last night I built a simple stand off charger with 4 AA batteries and the clip from a spare controller.
I'm not a big fun of the battery2battery charging but I had no time to build a proper charger (it will be my next project !).
By the way, I charged a car for 5 minutes and the battery inside (standard 60mah) was not even warm.
The car sprinted on my circuit for a very looong time, I had 28 minutes of driving time !!
28 minutes of driving time, ie no slow car ranting on the straight but good old driving time !! After 25 minutes of speeding I was tired and a sort of nausea was coming up !! Too much time !
Tonight I'll charge it for 3 minutes and I expect 15 minutes of driving time.
A note... with the antenna mod
http://www.geocities.com/bitcharital...modificati.jpg and the more serious charging I can control better, a lot better, my little car. It is more responsive in steering and the reaction time was minimized.
I'm now going to build a simple no timer NiCd charger with a LM317 as regulator. Stay tuned !
Efarel
