RafBR 2DOF Wiper Motor Cockpit

Hi again,
Can I use one 102 and one 122 capacitor ?
I did not put my hands on two 122 capacitors. Can you belive this?

regards

:hi:
As my components took too long to arrive i started to build my simulator.
I payed $ 81,00 for the aluminum, $ 25,00 for the galvanized plates which i cut to fixate the aluminum, $ 33,00 for the seat articulation and finally, $ 230,00 for the seat.

So far the plates fixation are working fine. The most problem is to cut, to bend and to drill it. If I had iron solderer I think I would not make it this way.

Here is another video that shows my simulator on its final version.

Rafa, the nice evolution of his work.

Too bad the same parts take time to arrive.

I also could not find the capacitors and do not know where to look.

The rest all my parts have arrived and the boards are ready.

Let's keep in touch.

:hi:
After a lot of work i finished my simulator frame ;P
I have already tested it and after a few adjustments I found the perfect balance for the center of gravity.
Here some pics:



Unfortunately althought my boards are ready I can not test them now. I will spend at least one whole week to update my work. My clients may become without of patience. :

Rafael,

Very good work, I liked the frame.

Almost bought this seat also, but I just buy one from $ 190 to lining then I here.

How is the production of your board?

Already tested it?

I'm having doubts about the source of energy has to be a 9 volt?

Grateful

:hi: kiko, thank you!
I think you should use 6v up to 9v power source.
I am using a 9v cellfone charger.
And about my simulator, I spend the last night testing the connection of the AMC to my PC and at 1st I took hours to install and run PONYPROG on Windows Seven but I did it!
After that I have trouble to make the PONYPROG to have access to the serial COM port (Windows Seven again) but after Google searching I downloaded dlportio-64, now have to press F8 each time I start Windows and select the option disable digital signature enforcement for W7 to use this COM drivers.
Now I can calibrate on PONYPROG ok, Prog I/O ok, select device ATmega8535 ok, program options ok, BUT when it comes to configuration and security bits gess what? I get the device missing or unknown device. :thbd:

So after spending the whole night troubleshoting this and reading here in the forum I made a check list:

1- Maybe the ATmega is broken;
2- Maybe I have to use a 14Mhz crystal (tried 18 and 22);
3- Maybe different capacitors instead of 22pf (Thanos told about dieletric ones).
4- Maybe re-etch the board;
and so on,

regards!

It is done! The cable i made (DB9 > IDC10) was not correct.
Now I could succesfuly program the firmware to the board :yippiee:

About the lcd, can I just connect it to any 5v to get the backlight or the little board is really necessary?

Hello Rafael,

I enjoyed seeing your work, and thanks for the tips to windows 7.

I'm working a lot lately and still without time to pick up and finalize the project.

My boards are ready, but have not tested this yet and Cockpit in half, as all the material already acquired but not yet finalized.

To control the motors and the AMC, I'm considering getting a netbook with windows xp or even less, what do you think?

Tell me when you make your first tests with the games.

Ah, for the video, which you'll use?

I plan on going to the projection screen, what do you think?

Take care

:hi:
Now I am stuck a little step foward. ;D
I cant play with potentiometers and motors. Things does not work.
I fixed the two green leds of the AMC that were inverted and I did a cleanup in the soldering mess.
Here some videos that show of what I am facing:

Note that in this videos I switched potenciometers with motors (my mistake) but it does not work anyway.
I hope someone have any tip because I am running out of ideas. :
Kiko, for the monitor I will use any standard table with about 70cm height so I can place the monitor realy close to me. :thbup:

hi
Tomorow I will buy all the components again and make new boards.

But I am afraid that that it is not the problem. Maybe I put some wrong component.

Im sorry I cant help you, but take picture of the bottom where you have it all soldered, the folks on here usually like to see that stuff to help diagnose

Thanks for your reply Shannonb1!
I started to feel frustrated with the lack of ideas but after I run a minucious continuity test I found one short circuit on the HB and another on the AMC.
Now it works! :clap: :clap:
here the video:

But before I become too confident I must to say that I can not have the LCD working. I tried to attach potentiometer for the contrast and it almost worked but all I have is one white row which I can adjust with the potentiometer.

To have x-sim controlling my motors and stuff, can I go on without the LCD for a while?
Which is the way to go now?
Please someone give me some link to where to begin playing with the motors!

Thank you Thanos for the boards and SirNoName for x-sim!

Today I did my first test with x-sim and the boards/motors and it was very good!
I figure out the USO connection/output string thing and played a while with the motors with the force sender test plugin. :thbup:
I dont know exactly what I have to do next but well, now I can sleep...
:lol:

X-SIM & AVR & HBridge

I have this problem with the LCD:

I am using a 10k pot for contrast control.

I really can not understand the Thanos LCD PCB so I followed this wiring scheme:

If I exchange my LCD for a LCD without backlight this problem will remains?
regards!

Hi, I found the LCD problem!
I plugged the RW to the ground and now it is beautiful!
regards!

Hi,
Just to clear my mind I ask: To have x-sim/rFactor/my simulator running I dont need Yoda2 or Force Injector, correct?
Thanks!

That is correct

You'll need rFactor, the Sender, the Profiler and your simulator, that's all.

Have fun!
Regards

URGENT! NEED HELP! :
I was testing my H-Bridge with the wiper motors and something strange happened.
When I turn on the boards the motors do not move. After a while playing with pots the motors start to move but mosfets temperature are too high, about 80-90ºC maybe even more if I dont turn off the power.
Is that normal?
I am afraid to burn everything!
please :
regards!

Hi egoexpress,
Thanks for the reply. I tested rfactor with the boards (with toy motors) and seem working great!
Now I just have to solve this high temperatures of the mosfets.
Up to 100ºC is normal?
regards!

Many wiper motors have common ground to their housing. So if you mount them to a metal frame they may short to each other! Or you may want to override their internal thermal protection circuit as well as some may cause problems to the mosfets! What voltage you are trying to apply to the motors throu the h-bridge?
