The Vicarage Orchard ~ new Lithium 10.5 volt Thomas' first run
The Vicarage Orchard ~ L10.5 volt Thomas CrAzY cOrNeR!!!
Muddy is that just modded with the 10.5 Lithium battery and not a motor upgrade with it? Is this the Lithium that is the same size as a "C" Battery? Very cool. He looks to hold the tracks very well for such speed. I am surprised that he didn't derail a lot.
Interesting battery arrangement there, looks like you are running them in serial which should deliver what 10.5v nominally? That's quite a bit to put through a standard motor as they are rated at what 3v? Although I guess to a degree it depends upon how much current its pulling...
Thanks Nigels..I don't know much about circuits and wiring, and my first try I hacked out the wrong side of the battery compartment and he could still talk but couldn't run. Now he runs but can't talk anymore..
As far as it works, it seems like the AAA 1.5 volt is in front of the 9 volt and the energy is being pushed through it like a nitrice cannister...if it gets hung up it bursts free, and goes incredibly fast for the first 10 min... if I change to a fresh AAA before it begins to slow, the 9v seems to last forever!! Does this seem possible?
Well I'm not a qualified electrician or anything like that, but I have dabbled with electronics a bit in the past and HO/OO gauge railways as well so I'm used to playing with circuitry.
It doesn't surprise me that the AAA is dying before the 9v Lithium to be honest. For a start the 9v Lithium would be likely to outlast any AAA even if the AAA were a Lithium as the 9v's capacity is going to be much higher (the mah/hour rating). However I suspect your problem is more likely to be that there is a resistance differential between the two cells and the AAA is simply being drained before the 9v Lithium. As I'm sure you've seen with many instruction manuals it always advises against using different brands or different charge levels of batteries, it is specifically for this reason because battery characteristics change as they are drained I believe.
I'll do a bit of research and see what I can find, it may be possible that you can run the two together using a component or two.
As for the sound no longer working, that's probably because it has a sound/processor chip which is designed to work at a specific voltage, so you'd probably need to put a voltage regulator between the batteries and circuitry - assuming its not blown already lol!

Wow...way to scramble my brain!! That is WAY over my head...I think we'll just play with it until it breaks someday and then go from there..
