Is there an easy way to connect M5Stack or M5Stick-C to old Lego Mindstorms Motors and Sensors (Robotic Invention)

Skink

here are some more interesting pages about the RCX.
Maybe very interesting for you if you still have so many RCX parts.

greetings skink

P.S. I'm waiting for two of the X-Base units, they're already on their way to my place

Thank you. For long I have followed the first two links. The third is new to me. Please let me know your impression on the Base X. If I have an NXT Lego then I will certainly by the base.

@liemph

No need to thank me, of course I will get in touch with you as soon as I have received them !
And tell you what my impression of the X-Base is.

@liemph

I had ordered the BaseX on 13 December 2019.
Today finally on 21.01.2020 they arrived at my place.
They are working very well, I will test them during the next days and make a little video!

Happy Testing !!!

Skink

I will test it at the weekend but for you @liemph I will test it with the adapters and the old Lego motors !

i Get touch as soon as I have tested it, it will only take a little while until Saturday before I can start !!

@liemph ,

Hello,

As you can see, you can connect all RCX engines and also the power engines to the BaseX and of course the old engines of the NXT as well as the EV3. For the power motors there are also adapters to connect them to the X-Base.
The X-Base can control both the direction of rotation and the speed of the motors.
For sensors you would have to use the M5Stack connectors, which are available!

I hope the test helped you !

@liemph ,
With this adapter and the adapter from power motors to the old ones you can also make NXT or EV3 motors from the old motors which you can drive exactly on angle ! (http://www.mindsensors.com/ev3-and-nxt/19-glidewheel-pf-and-rcx-motor-controller-for-nxt-or-ev3-)

You will need the following cables :

this one from NXT/EV3 to PF Power motor connector

this one from PF Power Motor Connection to the old motors

Thanks, a very nice video that explains everything I wanted to know. The encoder signal is also used by the Base is impressive. This feedback is important for a serious project.

Ok, this is another interesting way not to throw away old Lego motors. I am challenged to make those connectors. Awesome. Thanks.

Skink

The encoder signal is displayed very accurately and also evaluated very precisely. Of course also with the NXT motors and EV3 motors. I will see that I make a video the days once again where you can see how precisely he drives the set values.
@liemph
I will then connect a NXT motor and run it on different values of the encoder! The GlideWheel PF and RCX motor controller for NXT or EV3 cannot be mounted directly on the old motors, because it is designed for the power motors (on these it is mounted with two pins), but you can mount it somewhere in the system on the shaft of the motor. So you can make an encoder motor out of any Lego motor.
