Ill be using mine on a full/half scale Go Kart

actually i found a 24v  motor of a electric wheel chair and two marine grade batteries...all i can say is that is this thing does not turn i will be angry ... also i hope your plan works...i will have my electrical engineer grandfather help me...

Hey guys, I have been working on a servo for months now, and I present to you my findings and design for a cheap wiper motor servo! I spent probably..... 30 or so dollars on components and motor. I made some vids explaining the build.

Hi,

I'am french and your explains in youtube are too bad for my poor english...
Can you make a pictureof you h-bridge with name of all ic

Thanks

maybe you can use this

I see the potentiometer, the wires to the receiver,and two for the motor.
It is therefore with a microcontroller in addition that gives a complete servo electronics for less than 18 amps, but how many volts ? .

returns of a user?
Excellent address anyway thank you.

The same with a brushless?

thorstenhh

12 volts

Bong-Master

Hmmm intresting

Thank you Thorstenhh!!!!!

Finally a cheap and effective solution for those whom are electronically declined as myself. I got mine from lipoly.de daniel was very helpful! And it even supplies power to the receiver.

kustomkb What one did you get ?

this one;

And a test with a weight attached to the end of the servo arm?
Because it is in small movements around neutral under stress that electronic smokes

My Feedback: (1)

Yes polulu 12v 12 works very well the new style are programmable from pc just download the software

i use two of them

Is this thor 15 good for a wiper servo ?

Not homemade, but in this year will be available by us: [link]http://mammuthworks.com/products/mammuth-servo/[/link]

We're planning smaller, lighter servos after the first successfull tests. This one is the biggest for R/C world, we will use it for steering and for braking in the Rewarron.

Looks interesting do you have a rough price yet ?

csicso

Maybe the biggest around 600-700 USD

I'm really in need on how to make my wiper to steering servo. I've seen that schematic diagram above but don't understand them. can anyone just tell my how to connect the wiper to h-bridge like the L298n circuit.I'm really desperate on some advice.Been searching the net about how to make a wiper servo.Have already the wiper motor but don't know what circuit should buy to assemble them.Hope to hear from anyone one.I bought a 40kg servo but i got fried and have heard about the wiper servo.but i'm no electronic minded but really easy to be thought hope to hear from anyone.

Looks like a project I am yet to start, it looks like you are replacing the quad frame with a better chassis, Correct?

Seriously don't bother with the H-bridge, use a commercial product like the Baby Bully servo amp I linked to earlier in the thread, saves a lot of heart ache for non electronically minded builders. I would have ended up spending more on components than what the Baby Bully is worth, the H-bridge needs a control circuit that takes the input from the RC receiver and converts it to signals to operate the H-bridge, the H-bridge is only the high current motor switcher.

Cheers

Thanks for the responsed but still don't have any idea on what to make. I live in new zealand and don't know if we have the baby bully servo.is it a circuit or is it a servo?have spent heaps already on servo and it just can't steer my project. I saw some good video of wiper motor being the steering servo. Do you know how they do it? Pls need your help. I can be easily instructed on what to do.I got a wiper motor at the moment and thats it.hope to hear from you again or anybody there with a good heart.thanks

We've three different servo solutions, maybe one of them could help and you don't need to solder your H-bridge
