Creating a moving machinegun

[Jofaur86]

Hello, so? I say well done, superb work, have you found the solution to power it? weird that doesn't work with the rear lights? in principle an LED (red or orange) operates between 1.6 V and 2.1 volts? or not enough intensity? for the motor? have you checked with multiput in parallel on the motor?

Im inquiring about a relais atm, hoping they have one that works on the very low led power.

If that isnt posible, i just disconnect the smoker entirely and use that connection.

Working on the Sherman turret atm, trying to fit the MATO mantlet and barrel on there, which is quite a challenge i hadnt expexted tbh.
Got my FPV camera today and excited to see how small it actually is, that one is going inside the Panthers mantlet viewing outside the unused hole next to the barrel (where the gunners sight actually was)

…have you checked with multiput in parallel on the motor?

No, i havent, how would that work? Are you saying i need to use the multimeter to check the Volt and Amps of a led(connection) then a problem would be that the panther is the only tank i have at this moment (the Sherman (who has two taillights) still hasnt arrived) and has no taillights.

I do understand Watt, Volt x Amps and that Volt is a set value and Amps is powerdraw, meaning adding multiple devices to one conmection wont change the Volt, but will increase the Amps and thus the Watt (and affect the mAh of a powersource)

Or are you saying that if i connect several devices (or connections) the engine might work.

I watched a video about Relais and it seems thats what i need, but in the video they used electromagnets to move a connection, i have my doubts that the power of a led would be enough to power a elecromagnet of a suitable size (as i think i learned that the more coils, the stronger the magnet)

Please enlighten me (again hahah)

Yes your reasoning is good,
Voltage.....expressed in Volts
Capacity...expressed in Milli ampere hours or amperes, depending on the connected device
Power...expressed in watts, all this is called Ohm's Law, there are formulas to calculate this, but in our case? let's keep it simple, read below....
Maybe you have it? noted ? but my old brain didn't integrate the information!!! what type of plate do you have in the Panther? Yes, what I meant was to take a measurement (position C Continuous 20 volts or less if there is, without worrying about the polarity, then do the same test, leaving Volt connected, connect the motor and check if there is voltage, or if there is a drop in the connected motor?

What video, or do you have magnets to activate the relay?

I have the TK7.0 board, the led’s connector messures 4,5V but when hooked to the motor it drops to 0.07V

The video was years old from a dutch sience teacher, explaining how relais work, in his examples with pretty large electro-magnets.

OK, so, on the transmitter? Is there a “smoke” button? If you don’t use it? This may be the solution...you have to look at what starts when you press the "smoke" button, personally I would say, the resistance? I think the fan is constantly running,? take a measurement to see the voltage ?

[Jofaur86]

Sory from memory it is the CN 11 connector for the resistance

[Mindstorm]

The smoke button controls both heater and smoke ventilator, connections.
So disconnecting them both is essential.

Im done hobbying for today, but will look into your advice tomorrow, thanks

The engine fan, doesnt exist on the TK7.0 board it seems, i mistook CN and CH connectors, the connection i wanted to use is for the FPV camera, which i will be using.
So it seems there is no other option than using the smoke connection, eaven if i get a relais that works off a led-connection as i dont have a free connection that supplies the power for the MG-motor.
