LOL i know how you feel 😂, you’ve helped me plenty to be honest; thank you for everything! I won’t be offended if you sleep for days to avoid this haha. It took a while but the 3D printed flywheels on the motor shaft fit/move perfectly with the wheels (& yes you were completely right about the...

Haha yeah I’ve found out first hand the difficulties, definitely going to use a belt to drive it thank you! if I was to fit a belt on the shaft of the stroller wheel (and if it rotates, I need to check) I think I could make a simple belt with items in the lab; if not I’ll ask about a 3D printed...

Oh really helpful thank you! I’ll ask the electric and physics department tomorrow since the mechanical department didn’t have one. And yeah since then I’ve been looking up motors used for electric bikes and the motors that were used only had 12 volts/19 watts so I’m sure after I calculate the...

You’re not wrong haha, so even for the slope, there should more research on what type of slope we’re dealing with, in this case would a singular slope be more beneficial; the slope the experiment would be taken on, instead of the multiple scenario slopes And yes friction is usually on the...

And honestly thank you, your absolutely right, I went straight to the circuit, without a formal idea of the parts I would actually require, not wise; when measuring the speed I how many rpm’s I have in a minute with a stroller going up a hill to get the speed or should it be more focused if...

Haha yes yes, I guess when I heard, the description of the measuring device, I isolated it to one type, I can just get the weight of the stroller for one calculation and add the weight of the electronic components for the other calculation, to determine how much energy would be required to go up...

Oh a spring balance, what would be the appropriate way to measure the Nm on a spring balance? And if the purpose is to be smooth, wouldn’t having two switches accomplish that? So when you turn off the top switch, the charging operation is fully complete, and nothing is driving the stroller...

Yeah I see what you mean, I’ll find out if the school has a force meter, I doubt it but that would help; the system is only to assist, & not to completely drive it on it’s own, so as long as the motors shafts are rotating on the wheels, from the design of the circuit, the experiment should be...

Haha I can show you my search results, the only affordable batteries are the car batteries & most didn’t have prime so it would’ve been a waste of time, I don’t live in the uk but that would definitely be an improvement from 175 mAh & I will be adding calculations to this, like power, how much...

Well, all I know is that the voltage on the multimeter will read negative, so the voltage will display the same value but current doesn’t flow through, atleast from my perspective with this project, so I’m sure someone else can explain it better

@mfb hello, just wondering, would there be an issue of the batteries powering the the motor immediately when the switch is closed on the both the charging and discharging sections? Thank you!

Well I couldn’t find anything on amazon that fit what I needed for the experiment, so when I said that it was mainly from the limited experience with rechargeable batteries that I have, so I just didn’t find any 12 volt rechargeable batteries that was anything but a car battery. The 9V Battery...

Yeah wow, sorry, I was so focused on that, I didn’t even realize the whole circuit would be useless, would the polarity on the motors would be the same or opposite in the picture? To perform the operation?

Hmm are you saying something like this would need to happen so the battery can give electrical energy to the motor? Thank you for your help!
