Teensy PCB Ardumower (T-Mow)

[Sascha]

Yes that should work.
The producer of Matix MOW800 had give a comment on Facebook to my first test of the TeensyMower.
They want to talk

 

[LaurentS]

Well, I have more to talk with Bernard and you... yours are working... .

 

[Sascha]

Well, I have more to talk with Bernard and you... yours are working... .

At the Moment only for testing.
It is storm week here, no tests possible in the garden.
I took a look at the website of the manufacturers, all well-known mowers

 

[Sascha]

@LaurentS have you given up?

@LaurentS have you given up?

Hi Sascha, absolutely not, but I "work" on PETG 3d prints since 2weeks... not really easier things. The blue print is the last version and I'm working on HR-SR04 holders.

 

[Sascha]

Looks nice.
When you have time, can you do some tests?
The motor ODO test with the PFODApp-> 1 motor revolution
whether both wheels turn at the same time or one after the other?
I have some problems with the test.

 

[LaurentS]

Do you mean with the main PCB ? I haven't tested thisone for now.... .

 

[Sascha]

Yes wih MainPCB and PowerPCB built-in.
If you have time, you should install it in the Mower and test if everything works.
It still seems to be a bit of work and there may still be bugs.

 

[LaurentS]

Ok, I have many things to do, like drivers holders and to connect all parts together.

 

[Sascha]

One thing after the other

 

[LaurentS]

One thing after the other

As you Sascha, I 'm working on many projects at the same time... it means... One thing parallele to the other one... .
I'm building an astronomical CCD camera. But I will soon start this part of installation. Oups... maybe I also have to order my battery... seams to be a good idea... or not ?...

 

[Sascha]

Yes, I know that, but it's easy to get confused and make mistakes.
If you are still missing parts, you should get them in the near future before there are no more.

 

[LaurentS]

Battery, the screen and the RPI zero 2+ camera are (I think) the last missing parts.

 

[LaurentS]

OMG, I'm not speaking about the loading station.. I have nothing for this part of the project; the same thing for the boundary cable... .

 

[Sascha]

Hurry up, summer is coming

 

[LaurentS]

Battery ordered, I will watch this week end the missing parts.

 

[LaurentS]

Hi Sascha and Bernard, Battery with it's BMS are on place; already in playing with wiring... .

 

[Bernard]

Unfortunately my test with this motor driver fail again (First time was with hoverboard motor)
I hope it can work for you but you need to be sure the motor always start when PWM is send and not 1 or 2 seconds later.
In my case the motor make too long time to accelerate and brake for a correct management of the IMU and small roll movement and something more strange : sometime after direction change it start only after 1 or 2 seconds ??

Using the other driver work well actually.

 

[Sascha]

New Test with the new Motor Driver much better driving. The Stops are Motor Power Max.

 

[Bernard]

i think it's too fast ,what are the pwm max and min ?

Today i have build a new sender and discover again china do stupid thing .
My new INA3221 is totaly diffrent than the other one !!!!
