Gr1 is the 13.73 gearbox and the "worm" Gr2 is 406/24 = 16.9166 although the 406 is dependent on the accuracy of the disc diameter so it could be a bit higher or lower. but it should get you to the ri

It has been some time since i used the onstep bluepill so my memory has faded but have you tried the bluepill memory size test? they were available in 64k and 128k ( officially bluepills are only 64k

Hi , i haven't used these drivers so i may be totally wrong but i had a quick look at the schematics etc. in your first post you said you measured from the Enable pin to ground. it may be different on

Hi, they look like a nice product but bear in mind the small print. Output Power: DC 5V (3A Max) / 12V (2A Max) via the terminal interface reserved; Total Power Budget: 25W; IEEE 802.3at Compliant so

Also USB3 is extremely fast, capabable of 5Gbits per second, i suppose you may want that if you are shifting real time high resolution images around but if the images are stored and processed on mount

The other thing that is often done in other electronic systems is to distribute the power at a higher voltage and have local switched mode regulators. this is often done at 48 volts as per the "power

just a few thoughts. slip rings are only needed if you have a continuously rotational part so unless you want to track over several days you can just wind up a cable and then unwind it again when you

Thanks, that's basically what i intend to do when i get back to it. at some stage i will check what the 5v psu circuit actually is on the board compared to that schematic. It is difficult finding genu

that the circuit i am working with. I haven't had time to investigate it but the circuitry around the selector and 5v psu is dubious. for a start RC1K chip marking indicates it is a LMV321 which has a

I agree , particularly as the USB interface chip has a 3.3V mode, it is just incorrect wired. The only schematic i found is incorrect around the 5v regulator and there is something odd going on with m

I am a newbie to telescopes but in my simplistic view, happy to be corrected, you will want to use motors to A, go to a star, B Track a star as accurately as possible an C, maybe use a camera on the t

I had a play with SWS a couple of months ago and i hadn't used the correct version of the library. there was an issue that i generated a wifi site but noy any DHCP. i could access it from my laptop bu

I haven't used app via wifi i use Bluetooth but you have to tell the app to connect by pressing the three dots in the top right corner. don't know if it is my phone screen but i have to touch it for a

I have never used this option but i did a bit of searching and found https://onstep.groups.io/g/main/wiki/19055 couple of thoughts. the DS18B20 is a onewire chip, the DS3231 is an I2C chip so should b

SWS is the smartWebServer, check the Wiki section for details. Depending on your hardware, for instance ESP32's have bluetooth already in them, you may also be able to use the Android Onstep app. I ha

i am currently adding onstep to a friends telescope but it is not yet operational. it is a 200mm reflector on an eq5 mount and it resonates for several seconds every time you touch it. you can use it

some Onstep PCBs have the option of using onboard RJ45 sockets and join 4 lots of 2 wires to make 4 higher current connections but because they have RJ45 connectors on both ends of the "Ethernet" cabl

Hi, I have never used a S6 board but it seems weird you have blown USB ports, that would imply something seriously wrong so it will need investigating before you plug in the USB again. are the blown U

Onstep assumes you are polar aligned at power on ( or previously parked i think) so check you are aligned and also have your location time etc set properly.

What is "wrong direction"? does tracking move the correct motor in the correct direction, which will depend in which hemisphere you are in? if it is just direction of rotation of the motors you could
