Yes, I am aware the LED and the battery symbols are backwards. I kind of said I really couldn't remember. If I knew the video would get this many views, I would have made sure I got the symbols correct. You could knock me over with a feather. You do know I built the world's greatest flea circus, and the videos are on my channel? I built an animatronic diorama. I built a robot. A robot! I refurbish all kinds of stuff. But obviously people like learning how to make things remote control. Shows how much I know about this KZbin stuff.

79 year old elec tech here. Ray MItchel is correct you should use a diode instead of a capacitor to clamp the back emf. In fact the diode will cause the motor to stop instantly since it acts like a direct short across the motor when it tries to "Generate" a voltage in the reverse direction..... Thanks for informing us about the RX480 ! 😁

@waltahlgrim5508 Ай бұрын
I agree without the diode on the coils and motors you will get a large voltage spike when it turns off that can damage your circuits. Note the Cap is a good Idea for electrical noise while the motor is running
@demef758
@demef758 Ай бұрын
It's not actually a "short circuit," but a clamp that limits the CURRENT in the coil in a controlled fashion. By doing that, the voltage across the coil inductance is limited to the diode's forward voltage, about 0.7V, providing a path for the current running through the coil when it is energized (let's call it Io) to give it a place to go. The current will then be RAMP down from Io down to zero for a time equal to (L * Io) ÷ 0.7. This is a little understood reason for the diode clamp! Without it, the inductance will cause a flyback voltage to spike to unknown heights. Using a capacitor instead of a diode will cause a "ringing voltage swing" that will slowly dissipate the inductance current through the coil's resistance. A diode is the better way to go.

In the case of the solenoid or a relay, they are really inductors which produce a high voltage when switched off. Basically they oppose a change in current flow so when you switch off, it tries to suck current through the switch, resulting in a high voltage. You really should place a diode across the terminals to prevent damage to the switching transistor. It needs to be oriented so it does not bypass the current through the coil in normal operation. Therefore the current is drawn throught diode and allows energy to be dissipated without damaging anything.

Nice demonstration - right to the point. The only thing I would add, which I don't think you covered is that for anything electormagnetic it is not just noise but also the turn-off spike that is a problem. A diode across the load is much better to suppress that. A capacitor can do it, but you need to calculate how much energy you need to absorb to know how big a capacitor you need. The diode kind of works like the free-wheel on a bike - it just absorbs as much spike as there is. Those TIPs are a lot chunkier than necessary for a relay so are quite forgiving, but typically, if you drive a relay or solenoid with a transistor and you don't have something to suppress the turn-off spike, the transistor will die the first time you turn it off, or potentially worse, it will fail after just a few minutes of use.
@RandiRain
@RandiRain Ай бұрын
I'm pretty sure I talked about how a motor still turns after the power is removed, which makes it act like a generator. That's usually how I explain it. I've never had an issue using the TIPs, and I've not had anything on them before. No cap, no diode, and it was just fine. It depends on how nice the motor is. I've built many things with them. A lot have videos right here on my channel.
@tumultuouscornucopia
@tumultuouscornucopia Ай бұрын
@@RandiRain Yeah, I eventually saw a comment lower down saying the TIPs have a built-in suppressor - so that makes it a really good choice of transistor. You would not get away with it using a transistor that didn't have this. You did mention the generator thing, and the cap is good for that. But the spike from a de-energising relay is much more problematic than the generator effect (theoretically the max voltage from a relay is infinite, the spike just keeps rising "until something starts conducting", which often means "until something breaks")
@suvetar
@suvetar Ай бұрын
In general terms, it's also where you have a DC circuit, but there *may* be some AC there, after rectification for example ... the Cap will allow the AC wave to pass through it. I think this is why they call them filter caps, so it's not just for buffering reverse EM, but eliminating noise ... Even need them on 555 timers, super close!
@etmax1
@etmax1 Ай бұрын
Battery symbol is inverted, ie. the short bar is the negative. Also Kirchoff's first law says that in a series circuit there is only 1 current and that the sum of the voltages is equal to the total voltage so regardless of where the switch is located, the circuit will be off and there will be no current. If the battery decides to leak because of deep discharge that will happen regardless of the switch being off, it's chemistry of the battery and has little to do with position of the switch.
@dalenassar9152
@dalenassar9152 Ай бұрын
For the inductive loads, you need to connect a DIODE in reverse across the coil. I'm not quite sure why you use a capacitor. Also these loads (relay, solenoid, motor...) really need to be run on something with much more capacity than a typical 9v battery...especially if they are 'latched' on! This will deplete such a battery in short order. OVERALL...NICE VIDEO!!

Haha! That's wierd I have that exact motor that I bought for a tobacco grinder, but before I built that I quite smoking! SO I still have the motor sitting here trying to find something to do. This gave me some ideas, thanks! These RF units are far superior to the ones I was using 10 years ago too. Need to invest in some cheers!

Wait magic, in this case you did not let the "magic smoke" out of those components. 👍 What is really great about Randi Rain is the videos are real, the magic is in the devices. Most you-toobers need to watch and learn from her.

Well A New "turn on" for me has just been unlocked: Women explaining electronics.. lol but kidding aside, I found the pace of your explaining things and your honesty humbleness and attitude to be therapeutic as much as informative. Thank you! 👍🏼

Kool vid. Thanks for your personal insight into this. Some transistors 'latch' rather easilly. Meaning just the capacitance of your finger in the circuit on the base can enable the transistor, meaning it stays 'on' so long as there is voltage / current present. So it would remain on, even with no signal on the IO pin after it was pulsed a single time. secondly, Keep in mind, IF the load was a coil in a relay, solenoid, motor etc, that is to be energized / de-energized, a capacitor is not the most effective way to snub that. When the field decays, it causes an EMF surge to be induced in the circuit in the reverse direction. Those voltage spikes can be devastating to devices upstream. While a small cap will absorb some of that, a reversed biases diode should be used across the coil to shunt that extra voltage to ground. A TVS diode would likely be a good choice. That is the theory anyway. Someone else with more experience can clarify that :)

1st time viewer This was quite enjoyable. It's GR8T to (finally) watch a video without the HYPE and being OVER PRODUCED. It was like stopping by to listen but not being allowed to speak (lucky you!). Thank you for the sub-worthy video Cheers from So.Ca.USA 3rd house on the left (please call before stopping by)

I make an effort to try to keep things as concise as I can. I love watching these kinds of videos too, and it drives me crazy when they don't keep it going. I'm always saying, "Just show me you put all the screws back, you don't have to show me putting ALL the screws back."
