Since I aquired an Losmandy G11 mount without any goto provision I decided to create my own solution. I was a bit reluctant to use a Gemini, mainly because of the cost, but also due to the reliability since the servo motors are somewhat prone to failure. I also like to have complete control over the software/firmware so that no "show stopper" issues will ever be a problem for me. Looking around the 'net I saw other goto systems that seemed capable, but either they had needlessly complex hardware or were commercial systems that cost about twice what they should.
OnStep is a computerized goto system, usually for stepper motor equipped mounts though any step/dir interface motor driver (including servo) should work. It was designed, from the beginning, as a more or less general purpose system and provisions were made in the firmware to allow for use on a variety of mounts including Equatorial and Alt/Az (GEM, Fork, Dobsonian, etc.) It uses an LX200 like computer command set with a few extensions to suit hand controller-less operation.
There's a telescope hand controller App for Android (free in the Google Play Store,) an option to control through a website (Smart Web Server,) and a dedicated physical hand controller (Smart Hand Controller.) Or, on a PC there's ASCOM and INDI drivers for control. These options allow you to setup and control OnStep using a wide range of software including my Sky Planetarium, Cartes du Ciel, Stellarium, SkySafari, KStars, PHD2, etc. You can see most of the control possibilities in the diagram below:
Also, please visit my StellarJourney.comsite for updates, links toOnStep resources, my other astronomy software, or to see someImages taken with the assistance of my OnStep operated mounts.
If you find OnStep useful and would like to show your appreciation and support please consider making asmall monetary donation. This keeps me motivated and helps cover expenses associated with my projects.
STM32 is flashed!!!!
as already mentione in a previous post from me, I found some hints, that resistors on blue pill were replaced... especially resistor R3 from 100k to 10k...

OK I'm an early adopter.... Bleeding edge etc.
I ordered 5 with the SMT Fabrication, it was $20.00 for 5 and $17.00 shipping $37.00 total. Great price, and they had an 8.00 coupon available (no idea

Another down-side is that the through-hole stuff of the prior designs was mostly high quality, not sure what these $0.02 components are like.
For example, the power connector from LCSC doesn't have

One downside to this is if they run out of certain components one will have to wait, solder the SMT themselves!, or the design will need to be updated with a suitable substitute.

thanks Mike,
yes I always use the device-manager, to verify which com-port... to be honest - I'm still hoping, that I did a stupid mistake and the reason is not on STM32... but up to now, I double and

so disapointing... :-(
today I received my new STM32 blue pill... looking very promising - labeling on MCU was proper and looking like an original and not a clone. After soldering the pins, I put it

When ordering assembled you first export a BOM and "Pick and place" file from the "Fabrication" menu. Then generate the Gerbers and move to JLC PCB to order. Select the usual stuff qty, etc. then

There are at least 2 specs for the 38 pin modules. Generally this is the one you want.
Note the imperial dimensions 1" wide, 1.9" long and 0.9" O.C. for the pins. The wider module has the pins 1"

It's noted as such in the earlier design build instructions but having it on the schematic that way is a good idea so I took care of that.
Yes, EasyEDA has one-side assembly only.

Probably should specify the D! mini Pro if using the aluminum box.
Are all the SMDs on the upper surface of the board?
Do you have a part # for the RJ22s?
TIA

Hi Howard,
I have done runs of pcbs for a extremely low frequency magnetic wave group Im in. And distributed 400+ mudflaps for a cycling group too. So, I might help for UK/EEA people. I’ve also

I've never tested the Ethernet Addon with a Teensy 4.0 but that's right, you can't flash a Teensy3.2 or 4.0 in the same way as the WeMos D1 Mini.
Also, the W5500ToMax2 board needs to be a more recent

I don't want to get into selling h/w. Once I build and successfully test one I'll allow access to the design and others can do with it what they will.
Hopefully this won't require any iterations.

Howard,
I would be interested. I assume if the Ethernet addon (with Teensy 4.0) is used and not the WeMos D1 mini it will still require programming directly via
the USB Teensy 4.0 connector as usual

I had no problems with the FYSETC TMS2130 v1.1 on a MKS GenL v1 and Watterot TMC2130 and TMC5160 on a Fysetc S6.

I am not sure of the logistic difficulties or whether you would consider it but have you thought of mailing the problem STM32 to someone in the group who has lots of experience and success in getting
