| Other key design componentAight, as I said earlier, I'm guna now cover how we may be able to govern the actual turning on and off of the brushless motor.
The key to this section of the device is to insure that the 4-in-1 doesnt get fried, in other words, we can NOT pull all required power from the 4-in-1's brushless motor power output. I'm sure pushing 10+ Amps through that circut could do some very impresive smoke output and very little else. Soooo here goes the crazy stuff....
To provide power to the motor and this make shift controller, we will need to pull the power off of the direct inflow from the battery at the 4-in-1. We should be able to simply splice a ' y ' adapter to pull the power before it hits the 4-in-1
Alright, with the power source problem addressed, we can now cover the actual activation of the circuts (Controlling when the motor actualy gets power and when it doesnt...).
Now to accelerate the brushless we can simply incease the power being sent to it, not that complicated. Using this as a 'on/off' switch should be fairly simple. Heres the concept. Lets assume that the brushless motor takes 0 through 11.1 volts. Now, by simply requiring the input to this brushless ESC from the 4-in-1 to hit a specified level (say a minimum of 6 volts), the motor will start getting juice and will continue to get more as required based simply on how much additional voltage in coming into the ESC.
Heres how we will do this.
Transistors work by keeping a circut shut untill a specific level of voltage on one of the 2 inputs is reached. The + voltage that we have split off of the ' y ' adapter is to go into one of the 2 inputs on the transistor, and the brushed motor + voltage is to go to the other input on the transistor. By doing this the rest of the ESC is not given power untill the transistor is turned on by the brushed motor + voltage hits its specific level, at which point the transistor turns on and the straight battery power is allowed to flow through the now turned on transistor.
here is a VERY rough keyed picture of what this would kinda be like....
(=) is the battery
\
> is the transistor
/
(4) is the 4-in-one
(C) is the rest of the ESC concept design
(=)
\
> (C)
/
(4)
once the + voltage of the (4) increases to the pre-determined level, the transistor will complete the circut between the (=) and the (C) and the (C) is able to provided the required power to run the rest of the ESC and motor without frying out the (4)
WHEW! Alrighty.....if you have any questions about this or comments on any of this, PLEASE PLEASE PLEASE make comments in the comment section, even if its "cool idea, dunno if it will work, your a psycho, but cool idea!" post it! encouragement is what tells me that this is a mod that people would like to see done. Also, if you have any of the required electical skills required to actualy design and spec out any of the required components of this mod, PLEASE PLEASE PLEASE say so in the comment section so we can get in touch and see whats guna be required to pull this off... I'm conffident we can get this done, hell, with this simple circut we may be able to simply put a regular ESC on the (C) section of this and keep it even simpler... who knows!
Life isn't fair.. Luckly it's a game and cereal! |
