I bet. Also Ross barely knows how to embed video's on here let alone add a voice over.

LOL. I just wanna go fast.

L3MUR · 02-11-2009, 12:48 PM

"here it is" lmao. that was sweet. I might have to try this.

Vegard · 02-11-2009, 12:57 PM

Interesting video, but as long as you have to mod it to get it to feed fast I'll stick with my prophecy.

Nice DM tho

ShOrTBu2 · 02-11-2009, 01:32 PM

sick man, I think its way fun trying to see what we can get out of our markers... sure its not legal but its still fun.
reminds me of my ego vidhttp://vimeo.com/2734592
sick.

Cut the 2prong connector off of the battery tray, splice in 2 9v connections and shrink wrap. Unscrew the battery tray and remove it, replace it with 2 9volts and attatch with a strip of tape. Reassemble your rotor. I'll get pics of the mod this afternoon.

Now wire them in series and try it!

1st2the50 · 02-11-2009, 06:48 PM

whats the difference?

^^ In 2 words...MOAR POWER

nice video, I was wondering when somebody would try this.

Don't do it.

I'm very happy with the speed I am at now.

Looks like a clean mod to me. I'd like to know what the longevity is like with that sort of voltage. There is a bit of an offset though. While the voltage on a AA is a low 1.5, the amperage is 2850 mAh. A 9V has higher voltage but much less amps - 500mAh. It's typically the amp's that will kill electronics, just how it's the amps in AC electricity that will kill you while a 300,000 volt taser won't. Low amps. Voltage typically only comes into play when a device is demanding more electrical bandwidth but the battery can't provide it because of the low voltage.

Voltage is a measure of how much electricity can flow through at a given point in time, kinda like the difference between a small water pipe (low voltage) and a large pipe. The "water" would be the amps, or current. It would make sense that the two 9V's would speed up the Rotor since it's allowing for a bigger electrical "pipe" to get the maximum amount of amps to the motor at one time (cumulative 18V and 1000mAh), whereas the 3 AA's has a cumulative voltage of 4.5V (smaller pipe) yet higher amperage (2850mAh). You won't get as much battery life off of the 9V configuration, but you definitely will get better performance. I doubt that the higher voltage would really damage it much since the Rotor doesn't have the really sensitive circuitry like Gangster boards do.

I plan on getting a voltometer to test what the output is at the plug. Reading posts like the one above makes me wish that I knew more about electronics.

Don't forget to check the amps, too. A cheap multimeter from radioshack can do that. I'd be far more concerned about the amps than voltage, but the amps will be less from the two 9V's (total of 1000 mAh) than from the three AA's (8850 mAh), so it shouldn't be a problem. Now if the 9V batteries had an amp rating of 4500 mAh you would be in the danger zone. It's just the 9V's delivery the amps faster to the motor as it eats them up than the AA 1.5V's do, hence why you get the speed increase. More amps/millisecond = faster motors.

mAh =/= mA

Current draw will be based on supply voltage and resistance in the circuit.

junkyardlisp · 02-12-2009, 04:29 PM

well 1st2the50 was telling the truth, it works! I wired them parallel(which means both positive wires from the 9v batteries go together to form one and both negative wires go together to form one to the hopper) and it's like night and day. The motor never got hot through five pods of paint and no paint was chopped through those five. Only now its the hopper dye promised me! Thanks again 1st2the50!!!!!

Your right, they are not the same but they are relative. The measurable term "mAh" is milliamps per hour. It's used to give you the ideal maximum of a batteries capacity, too. So for example a 2000mAh battery can give 2.0 mA of current for one hour or 4 mA for 30 minutes before it's expected to die and 2.0 mA is the batteries top amperage. The amount of power draw from the device will determine the maximum lifespan of that battery. A 2850 mAh battery could theoretically deliver a maximum of 21.5 mAh for one minute.

While they are not the same they are relational to each in my description.

xluben · 02-12-2009, 04:59 PM

The mAh rating of a battery has nothing to do with it's ability to blow a motor.

mA is a measure of current, you can think of it like speed/velocity in miles per hour
mAh is a measure of current * time, similar to how miles per hour * time would be miles!

If your car can go 400 miles on one tank of gas, that is not the same as saying it can go 400 miles/hour.

YES, the 2 9V's in series will have a shorter battery life
YES, they will see more current draw due to higher voltage
YES, they will make the motor spin faster
YES, they will burn out the motor faster (but not because of mAh ratings)

V=I*R should give you a good estimation of how much shorter the battery life
will be. R will drop out, voltage is 9V vs. 4.5V, so current draw is 2x. Electric
charge is (for example) 1000mAh vs. 2850mAh, so about 35% of the original.

So you have 35% the available power, and it is drawn twice as fast. That
means you will get approx. 17.5% the battery life you would from 3 AA's!

Maybe I am misunderstanding what you're saying. I think we're both on the
same track, but some of your statements do not make sense in to me. I hope
my explanation is clear and (hopefully) error-free

themonkman · 02-12-2009, 06:23 PM

I think I was merely incorrectly taught about the relation. Forgive my ignorance, but I believe XLuben is correct. I thought there was another way of adjusting the rotor speed. Isn't the hex screw on the back of the motor a speed adjuster, or is it only for spring tension?

It is only for tension. I believe motor speed is based on how long the microswitch is open.

Correct, just for tension. Incorrect about the switch. Switch mod will only
affect how long the motor spins before it shuts off due to tension. Similar to
what the screw does, but a much less desirable implementation.

The only way to speed up the motor is to increase the voltage, which this
mod does. I don't doubt it makes the hopper feed faster, but it will be slightly
more stressful to the motor, and have much shorter battery life.

Hell yeah! Thats why I made this thread. Enjoy your haulin' *** loader.

I'm diggin all the technical stuff I am reading as well. Thanks to everybody who is contibuting info.
