WARNING – The drill battery in the circuit diagram is drawn backwards by accident. The plus sign beside the drill battery should be a minus and the minus sign beside the drill battery should be a plus sign. That means some of the red and black lines should reverse colors too. The black lines going to and from the drill motor should especially be red for clarity, just as the red line going to the source should be black for clarity. Everything else in the video, including how the circuit is ACTUALLY wired up and the MOSFET explanation is correct. Unfortunately (or fortunately) there have been so many useful comments that I’m reluctant to remove this video.

AWESOME, BUT GET RID OF MUSIC!
Seems you are a pro . I’m trying to remote control a 350w brushless Motor Controller with remote controller . I got a 4 channel ppm Receiver . If I connect this receiver to a throttle signal will that work ? What do you think ??
Interesting video, however what power rating is your drill motor at 12V as the Mosfet IRF614 data sheet drain current is 2.7A max?
My aeg drill pst mosfet overheating momentaly .handle became hot fast.why
I followed the diagram but I assumed the wires coming from the transmitter were the legs of the preexisting drive motor.?!?
dud, the drug music could be used by the investigators. it would make anybody confess! it makes your video almost pointless, why are you doing this? are you doing drugs?
Best Video ich saw 4 long time! Thanks!
Will these work for other rc cars as well with a transmitter and receiver operating at a low voltage(say 4.8v)??
great video…I have an old drill and I want to use it for pulling HDMIcable if possible can you explain how to use it? with DPST switch without (remote control ) thanks in advance
I see what looks like 4 mosfets in a two speed RC car. I saw cmos on them. I am looking to use them to turn on a lighting system in an RC plane from servo. Any chance the signal wire straight from servo can activate the bias? Does the first part sound like the correct piece? Where do I look up parts online to match what I salvage? Please and thanks.
sir can you please tell me what are the various components present on an 30 A brushless ESC whether resistor's, capacitor etc.I cant find it anywhere.please
does the drill gave the same output???
biasing，i learn this before in uni
those wires coming out from rc car are battery wires or wires for drive motor.
always enjoying your videos man… keep it up
I like it many many
Crystal Clear Style of Explanation.
i took a two radio coils out of old am fm radios that plugs into the wall and also i was useing can. you use them what's what's you're input on that
ohh soory i ment to say i got the loop without the antenna wire that go's around the loop at the yard sale I got it from. that came with hiss am fm radio that he had
Andrew here i put magnet wire around the am loop antenna wood that work for the am loop antenna or no. I went to a yard sale he did not have the wire he only had the am loop what do you think
can I use a metal bed frame for a ground or no
I tried my metal bed frame and the outside watter pipe for all ground connections it still does not work so what do you think
hi andrew here I was making my am christel radio by watching you videos and I did everything right. and the coils also it still does not work do you have more information on thes problems
so how do you connect them in parallel do u know?.
can you add more then one am turner capisters to you're am radio
can you have more then one am tuner capacitors yes or no
why didn't you use a relay they are much smaller then a mosfet with a heatsink on it?
Could you not just reduce the gate resistor so that the 3v (from the toy) yields the desired 1.4uA gate current…or sufficient drain current from the drill battery to run the drill motor at 2A?

Excellent video. I noticed you have the load connected between the drain and the neg rail, usually you would have the load connected between the POS rail and the source of the MOSFET. The way you show clearly works, but usually results in lower voltage across the load and possibly switching problems. I normally use a 100 ohm to 470 ohm resistor on the gate, and from the gate to the source(NEG), I would use a pull down resistor of 270k to 1M for reliable/fast turning off. 🙂 Keep in mind you can also use a "Logic-Level" MOSFET. They require very low voltage to completely turn on. Some as low as 1.5V.
+Tejas Shenoy They do perform much the same function. Relays are a much older tech, going back to the 1830s, and it's cool to see their uses back then, and still today (I've used them for automatic generator starters in solar systems.) A MOSFET requires very little current to keep the drain to source conducting, whereas a relay requires you to keep a coil energized, which is basically an electromagnet, and so that would require more current. I'm still new to MOSFETs but I've read of frequencies in the hundreds of kilohertz and even megahertz which I'm pretty sure you can get with relays.
PS. If you want people to be able to reply to you then you may have to go to your Google+ account settings and set "Who can comment on your public posts?" to Anyone.
when to use a MOSFET and when to use a relay? arent they used to perform the same function? +rimstarorg
hey rimstar check out the "tested" channel bb8 droid teardown
It worked, that's my take away from the vid and, certainly congrats are in order when working with new devices. For sound, no problems here, was just general b/ground music. External JBL single speaker (lol different huh).
A tip for heat dissipation in the final design – I use a coin superglued to the back. USA 1c for small transistors, up to a quarter for MOSFETs that are not running constantly.
get 2 mosfets make zvs driver and have fun induction heating and arcing with flyback transformer. note everytime you experimentally start the circuit you have to do it trough 12 v headlight bulb in order to make sure the system works. i recommend 4 irf540n in twin groups. they handle hours of mistakes when good heatsinked
Just a little something I noticed, it looks like the drill battery is connected the wrong way round in the schematic, I don't know if anyone else has pointed that out.
