I don't know. The motors have no data sheet. With no load they pull about 2amps @ 12v. They should NEVER stall.

Also, I have updated the board a little bit. I had a few traces going to the wrong place.


EDITD:

I forgot to mention I get lots of errors when I run the DEC. Most have to do with the via's not being the right size, however, I just used the default… I never changed the size. Any ideas?


Thanks!

So, what you are saying is that I am not microwave safe? There goes my microwave hair removal idea.


LOL

I will double check the wiring and run the DRC but I believe it should be ok. Thank you so much for your help with this project… I would have been lost on my own!

I saw in a previous thread about this problem, that the wire length should be less than 6". Why? And why would changing that specific wire length solve the problem, but changing any other wire length not help?

Probably electrical noise.


Try "braiding" the cables together. If they are all raped around each other I't might less the noise. I don't know why this happens, but it has worked for me in the past. Make sure you have a capacitor running from your power to ground.


Best of luck!

I added it in.
 

Thank you.

This is what I bought…

If they work I think I will leave the PCB as-is because I would be afraid I would mess something up in my effort to make it look neater.

Thank you so much for all the help you have given me! Hopefully everything I have learned in this forum will help me when I go to get a degree in Electrical Engineering next year.

I believe that it is finished!
264  Using Arduino / Motors, Mechanics, and Power / Re: BTN7970 Motor Driver [Update] on: August 06, 2013, 11:07:50 am
I was able to make all the changes except connecting the capacitors directly to ground. How do I do that?

Thank you so much for all of your wonderful help!

I get it now! How is this…

I'm working on building my own motor driver from the BTN7970. Maybe you could build something similar? Just another idea. Also, Trossen Robotics sells nice motor drivers.

I have to say that the best smart tv I have used would be a  Samsung! Why do you hate them? They have, few glitches, regular/quick up dates, and have good performance! The app store is also good. I would never by a smart tv that is not Samsung!

Give us some more info. I love coming up with names but I need more to go on…

Microwaves are very dangerous! I don't even own one! They alter the food that they are cooking and many leak radiation!

Never use one!

I was able to do everything except keep the power from having to go through a via. I was just not able to think of a design that would work. I did add a few more vias so hopefully that will help. Also, the motor is only 12v, and i'm guessing around 5 amps. (no data sheet)


Do you think this one will work?


Thanks!
