Cunning Turtle's Wiki is no longer valid, but I saved everything from it years ago. I have built 2 of these from scratch but I cannot get them to work. I know they are built correctly, so I'm guessing it's something to do with the firmware. If any of you are willing to revive this project I will supply you with all the info that I have including the BOM and firmware from the creator. I have 8 PCB's left that have not been put together yet along with everything needed to assemble them and even order more if we can ever get one of these to work. I just need some that that is really good with electronics and fully understands how to make this work. Apparently it's over my head.
Interesting... Would be nice perhaps if the there was some remote way to make the "servo" to "continous rotation" change... maybe a second channel input? Eitherway, I think this is rather brilliant!
hello. how can i buy 8 pcs of this kind of rc stepper driver old or new version. I have a project in my university and I need them and I try to find but no luck. please let me know how /where cans I buy old ,New version. please help :)
Hi, I have made two of this but none works. I have programmed ATTINY without any problem. I even soldered 4 leds to see the behavior of the exits but they are always on. Once in a while when I press the button the LEDs are flashing indicating action. However, they do not even change the cadence with the change in the frequency of the pwm, and when I remove the power, it no longer works again.What will be happening?
Quick question, can you make this pcb kit run 1 amp per coil or 1.5 amp. Maybe swapping something to a beefier part? I was planning on using a 4988 texas instruments driver which i have a few but then i gotta have something drive the steps.
I desperately need a couple of these controllers. Your site is broken and your online store shows out of stock. Is there any way possible that I can buy these? If not, can you share the schematic and I can make them. I have no other way of contacting you, please help! :)
I'm in the same boat, would LOVE to pick up one of these boards for a project I'm currently working on. Randy H, where will I be able to find them? Thanks!
Alright, so I'm incredibly new to electronics and I really need help, is there anyway to connect more than one motor to your board thingy, and where do I get that board thingy. Please help, I really need some guuidance(I'm supposed to build a robot arm for science olympiad but I dont even know where to start
I'd like to have a couple of these to build a stepper driven RC tank but as been noted before, they are no longer in stock. The bare PCB is still in stock yet I cannot find the partslist or diagram. I presume these are on the linked wiki which is offline. I have not been able to find a easy to use replacement. Does anyone have any suggestions?
@AllenKll There is a way you can change modes without pushing the button. The button is tied to pwm input pin. When it is held down it pulls the pwm pin high. So... if instead of a real pwm signal you made the pin high for at least 3 seconds it would cause the RC stepper board to switch modes. Also, the chip saves the operating mode to EEPROM and restores it on power up. So if you left it in "continous rotation" and turned it off it will still be in "continous rotation" when you power it on.
Hey, Cunning Turtle! I would very much like to get one or four of your controllers for a wooden rc lorry-track for my son. It's so hard to get in touch with you, what would be the conditions??! Why does it seem that it's discontinued? pleezzz...
Out of business from the look of it! Damn it, this is exactly what I was looking for. If anyone finds another board doing the same thing please post a link up here, I've been searching all morning and drawing a blank (or too $$$!). CunningTurtle guys: if you ever get back in business please let us know, thx. Looked like a niche product...
I just placed 2 orders for enough parts to build 10 of these. I'm sure they will go fast! Once I get the first one built and working I will make another post on here asking if anybody else in interested. (This is something I have been waiting for for a long time now, but the original poster apparently is no longer interested, so rather than just giving up I decided to take matters into my own hands. It's a little more complicated than I had expected, but I've got it all figured out now)
Not sure yet. Still working on getting them up and running. Once I do I will place a much bigger order for the PCB's and components which will drastically reduce the cost of each one.
I have the PCB's and all the components. I built 2 so far. The problem is that no matter what I try I cannot get the motors to respond to the receivers output signal. There is clearly some missing information that the original poster is leaving out for whatever reason. When I get some time I will look more into the firmware and see if I can find somebody that knows a lot more than I do about the electronics.
Any chance of reprogramming the Attiny to be able to work with PPM input instead of PWM ? Not getting it to work with my taranis tx and frsky receivers as i think the output is PPM ;(
I'm in the same boat, did you ever get yours to work? I have tried different radios/receivers, stepper motors and even reprogrammed the firmware twice. Nothing happens no matter what I do.
You could change the max rpm by editing a config file in the firmware and burning the new firmware back on. We have a tutorial that shows how to do that. www.cunningturtle.com/wiki/index.php?title=Upload_firmware_to_the_Radio_Controlled_Stepper If you set the rpm too high the stepper will no longer spin. The default maximum is a 100rpm.
Cunning Turtle oh really? so i can change the max rpm but it wont work then? =/ i need max rpm around 2500/3000! and one question... how expensive are the shipping costs to germany? thx :)
Hey Mate, if you are still interested let me know I have got the plans from him so I will have these available for purchase. Chuck me an email @ lukewalker952@gmail.com and I will give a quote for shipping to your area. Cheers

I hope to have a few of these built soon, I will let you guys know how it goes. If there is enough interest I will make another larger batch.
any chance of fixing the website. i am extremely interested
Hi there, just click the link in the video's description. It takes you to the wiki which has the schematic diagram and the source code.
I could really use one of these ASAP

Will there be any chance of bringing back this kit or at least be able to get the board? I would like 3.
Where can you buy it? Maybe there are some replacements?
can this pcb handle bigger stepper motors?

Still need these?
@@mochanic5498 sir can i get a pair of those?
This can be done by flysky?
Hmm i'm stuck here its clearly not a ppm pwm mather as i used a servo tester and still no good results...?
Buenas. Algún link donde se pueda comprar ese sistema ?

Hi Randy, put me down for two! Any idea how much they will cost?

Did you end up getting this ready for sale Randy? I'm Interested in 2

Hi, does it work with 4 wire stepper motor as well?
how to connect it with 4 or 5 wire stepper motor
we only use it for small nema23 motors under 2A
So a stepper motor is basically an industrial servo motor?
Any chance of reprogramming the Attiny to be able to work with PPM input instead of PWM ? Not getting it to work with my taranis tx and frsky receivers as i think the output is PPM ;(

+Cunning Turtle Hey. Nice Job. The link you give is not working.
I believe it has to do with the pwm signal and max number of steps. you should try using an arduino board for higher rpms
Hi! Where can I get the board? Thx!!
Hi were can I buy one???
Help me please.
I need this controller
I need this to RC a power wheel..
Where can i buy?
any possibility of getting these in stock??
