Hardware Development / Re: AstroEQ Basic Hand Controllers
« on: April 20, 2017, 12:48:12 »
Hi Tom,
This looks to be a great addition.  I've started building my own DIY controller as per your design (nothing fancy)
As I have a v4.4 it would be good to know what else I need to modify to the hardware.
Cheers

Hi Tom,
Noticed this thread and wondered what this 'push button' hand controller might be? Is it something we could buy or would it be something we could need to construct?

I noticed that there is now a version of KStars Lite for Android which supports INDI:https://www.google.co.nz/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjh2uC79tvSAhVBKpQKHSftDp0QFggYMAA&url=https%3A%2F%2Fplay.google.com%2Fstore%2Fapps%2Fdetails%3Fid%3Dorg.kde.kstars%26hl%3Den&usg=AFQjCNFXOgUSqwavl2Z9BW7_JAXUfowpmQ&bvm=bv.149760088,d.dGc

If I had a Kstars/EQMod server on a raspberry Pi connected via wifi to the Kstars lite app on my phone, could I direct the mount without a PC?
Cheers

Capabilities Question / Re: New AstroEQ Bluetooth modules
« on: April 17, 2016, 01:08:13 »
Hi Tom,
Did you get around to building the new bluetooth at Easter? Would it be something I could plug into my existing AstroEq and if so what are their capabilities? i.e. Would it be possible to connect it to an android tablet/phone via something like Sky Safari App?
Cheers

Capabilities Question / Sharing a PSU
« on: July 28, 2015, 11:34:00 »
Sorry this question is a little left field
I have an AstroEq with 2 Nema 14 stepper motors (0.8A) and the main power supply from you (12V 5A).
I'm looking to add an ASCOM DIY focuser using an Ardunio nano, Easy driver and a stepper motor; likely a geared Nema 14 (0.8A) or Nema 17 (1.6A).
I would like to share the PSU (there are limited socket out in the field) with the focuser but I wanted to check that I could run both without issue?
Is the supplied 5A PSU sufficient for the Nema 17 or would I have to fiddle with the current setting?
Many Thanks

AstroEQ Support / Re: Motors won't track
« on: April 23, 2015, 11:48:43 »
Hi Thom,
So I've taken some time to check the wiring and think I tracked the source to the connectors in the RJ11.
I've soldered them properly this time and the motors seem to working, however I think I've screwed up the current settings as they get hot very quickly.
So my question is how do I know where the minimum current setting is so I can work out what I should work upto?
There seems to be a 'flat' spot on the dial but where should that face?  I have a basic digital multi meter if that helps?
Cheers
Andy

I've pulled the motors from the mounts and they are now behaving. I can see (and feel) them stepping at small intervals.
The is a hissing coming from them but adjusting the current seems to reduce but not eliminate this. Is that normal
One thing is that I can 'force' them to rotate when powered on but not on the mount, but when on the mount and powered on, I can't move them.
Oh well, I''ll try and configure them on the bench and then add them to the mount when ready.
I'm testing them using the firmware update tool and as that gives me the ascom tester. What else can I adjust from the config that might?
Cheers for the assistance.

I've spent a few hourson the problem and still a bit confused (admittedly that does take much  ???) and not got a solution yet.
I've tried to rewire the connections as suggested but think I did it correctly the first time as I saw the behaviour you mention when I tried to wired incorrectly.
The motors data sheet gives the connections as black-green for one coil and red-blue for the other.
The RJ11 give connections 2 to 5 so I've connected as 2-red, 3-black, 4-green , 5-blue. Does that seem right?
With this got the RA motor moving at the higher speeds seeming fine. The single step does seem to work, but the noise comming from the motors isn't great - a like durr with a brief pause every second. Changing the current make the noise louder but also heats up the motor much quicker so not really an option.
The DEC motor won't move at all on a single step, but will move at higher speeds.
I'm starting to wonder if it that the RJ11 connections as they are not the best.
I'm not sure what else to try as the connection was only the bit that I've done.  :-\
Any suggestions?

Hi Thom,
The motors are the same ones you suggest on the FAQ http://www.omc-stepperonline.com/nema-14-bipolar-stepper-54v-08a-18ncm255ozin-14hs130804s-p-93.html
I've played with the current limit still have the issue. Changing the current alters the tone of the noise and they get warmer.  I can get the motors to move but not take a single step at a time.  played with the ascom controller and can get it to move when the rate is set to 2 or more, but not at one. I'm using the custom pulley config as I've sourced the parts as the FAQ suggests
Any suggestions?
Cheers
Andy

AstroEQ Support / Motors won't track
« on: April 04, 2015, 15:07:44 »
I'm trying to set up my astroeq on an eq5 mount with the NEMA14 motors with a custom pulley set up.
I've got the scope to move when I use a high speed slew, but the sideral tracking won't move it at all.
The motors just 'hiss' or sound like a tapping noise. The pulleys are on firmly but easy to move manually and don't move even when I've had no load on them, they still don't budge. Any ideas what to do?
Cheers

Capabilities Question / Re: Using DIY motors without a PC
« on: January 19, 2015, 11:57:13 »
Hi Tom,
Understand time is always at a premium, but would be great if there is something I can 'throw together' to 'replicate' the basic tracker handset mode - but sure it'll be more complicated than that  ;).
Getting the bits for my DIY motors together this week so should be a fun build.
Cheers
Andrew

Okay, Sent payment with UK address. Let me know if there any problems getting it out.
Cheers

An AstroEQ available? I'll have one with a PSU and leads?
Also when would it be ready for? I live out in New Zealand but have family coming over from the UK in early feb who could bring it.

Thanks for the info. Would the hand held likely be a DIY project or something bespoke.

Had another (wacky) thought and is it possible to run an AstroEq via a RaspberryPi.
I have one and could add a basic touchscreen with one and also run it off a car battery as well.
Not sure what software I could run to track with or if it's be powerful enough?
I don't mind tinkering but my coding ain't up to much.

Capabilities Question / Using DIY motors without a PC
« on: January 17, 2015, 11:06:36 »
I have a Skywatcher 200p on a eq5 mount and I'm looking to add motors to it.
I hope to learn the dark art of astro photography and add on an autoguider (via a webcam) at some point.
I've been looking at the options and the "Enhanced Dual-Axis DC Motor Drives for EQ-5"
http://www.firstlightoptics.com/skywatcher-mounts/enhanced-dual-axis-dc-motor-drives-for-eq-5.html
seeming a basic but workable option until I can move up to a HEQ5. I would be willing to build my own motors and add an Astroeq for guiding.
Thing is that I live in a rental and the garden is very poor for observing so I need to have something that is portable and can work in the field - i.e. sans laptop and main power.
Is there a way to have basic tracking like the skywatcher kit would give me using diy motors? I'm assuming the DIY motors would be different than skywatcher ones (i.e. amount moved etc) and I could not configure/adapt the hand control to work with them? Also can I run the AstroEq of non mains power? i.e. a car battery?
Cheers
Andrew
