Hello,

Fantastic. The 5V 4amp switching power and Adrino MicroUSB dongle are powering up the PI successfully. Now, I must wait for clear skies. Thunderstorms are coming.

Best regards

Hello,

Thank you these options to power these RPI 3B+ models. Supposedly, RC models are claimed to not need heaters. None are in my plans.

The USB standard for pins supplying power is 2. Running is parallel increases the amps and keeps the voltage the same. The 3.0 standard uses two connections (micro USB and USB-C) in parallel to give increased current.

Most MicroUSB cables are just 1.2 amp. Finding 2.5 amp cables (parallel) is not on any manufacturers’ minds.

Looks like a 5V 4 amp switching power with a micro USB port is the answer. These don’t exist on Amazon.

Hello,

In a Raspberry PI forum galaxy far far away, a claim was made the this error was an OS problem and just update. Well, today is year 2019 and updates a well past this problem.

I am attempting to create a personal portable solution. I looked at the PSU and it says 5V @2.5amps. USB 3.0 is the same. The PI PSU is too short. So, a long USB was purchased and the appropriate USB 3.0 USB. Length of cable can degrade power. But 5’ shouldn’t degrade that much.

Current USB 3.0 is a two plug setup. So, the supplied PSU works. Any replacement (USB battery, plug battery, or USB 3.0 base with standard USB 2.0) generates this error.

Are there any other options for power of the Raspberry PI 3 B+ ?

Hello.

I figured it out. I must of inadvertently clicked off INDI Server. Live and learn. Enjoy.

Hello,

I am setting up for a new event. However, EKOS is not starting INDI server. The message is cryptic and logs do not appear in the LOGS directory. I have deleted Profiles.db. Where else should I be considering?

Thank you.

Hello,

Thank you for your reply. Yes. When tracking an object, RA must move in with the rotation of the earth. However, Parked is a stationary position. Nothing is tracked. So, this counter then is the delta from original position it must add to be inline with the rotation of the earth in the current before the next tracking event.

I thought I might have turned on something or had a corrupted file that was causing a fixed position to be counting.

Hello,

Consider copying Scopeconfig.xml to Scopconfig.old. Then restart EKOS and reconfig the mount driver. Could be a corrupted ScopeConfig.xml. The other option is ParkData.xml. This file can be corrupted also.

Hello,

I am working with EKOS and KStars with my custom scope. In EKOS the Telescope corrdinates show the DE to be fixed at 90.00 but the RA keeps increment beyond 0. At the present, it is 10:22:16. This almost looks like a timer. Parking the OTA resets the counter to its position. Is this a feature?

Hello,

The solution to getting SkySafari 6 Pro to talk with the INDI SkySafari driver is described in another thread. This topic is closed.

John Robison replied to the topic 'SkySafari 5 and 6 Pro' in the forum. 2 months ago

Hello,

Wow! I have SkySafari 6 Pro working. I will state what must be working prior to getting this working.

1. The mount must be working in INDI with 0 errors.
2. The SkySafari driver setup is crucial to getting this working
2a. The syntax of the mount driver in INDI must match in the Options tab in both boxes of Telescope.
2b. Save the config.
3. Disconnect from Device Manager. Disconnecting from the Driver does not relink the SkySafari driver to the Mount driver according to SkySafari 6 Pro.

When everything is setup in INDI (Mount and SkySafari are linked by syntax, the iOS version of SkySafari 6 Pro will connect and control the mount. My description here differs from the description of the SkySafari driver on this site. What I am describing works for my custom mount.

Mount: Vixen Great Polaris from 1984
Tripod: Vixen Hal130SXG
Pillar: Vixen SXG 8" pillar with GP adapter
OTA: Orion 6" RC
Guide Scope: QHY5L-II Mini Guide Scope.
Controller: AstroEQ 3.90
INDI: Raspberry PI 3B+ running Astroberry (Current version)
Motors: NEMA 0.59 Nm RA and DC paried 3:1 belted gears.

Hello,

Good News! Looks like more than one file can be corrupted when going thru testing. Deleting ParkData.xml was not the problem. Deleting ScopeConfig.xml fixed the error. Now, the problem is gone. When deleting ParkData.xml did nothing, I looked at the ls output for other none default XML files. ScopeConfig.xml caught my eye. That was the target and it was the broken file.

Hello,

I just seem to have started to receive the same problem here. Everything is updated.

Child process 4671 died is the error. This happens at step 18 after Client 6 New Arrival.

Hello,

I think I found the latest Issue between SkySafari and Indi. I am now on a RPI 3b+ and attempted to use SkySafari as described in the documentation.

After several attempts, I check the log and find that a miss-match check is being conducted. If telescope mount equals EQMOD in the driver and Meade LX 200 GPS is SkySafari, then a mismatch error is thrown.

ERROR 241.197116 sec : Internal client is not connected! Please make sure the mount name is set in the Options tab. Disconnect and reconnect to try again.

Oh well. Time to dump SkiSafari.

Hello,

Network communication always begins with negotiation. Clients request something to reply. Servers acknowledge Clients. Under KSTARS, remote access is simplified to the macro HTTP protocol when wireless and wired.

So, my request are these.

During a remote session, (a client initiates a HTTP-GET SETSERIAL BAUD 9600 BIT 8 PARITY 1 to KSTARS), which KSTARS applet should respond?

Doesn't KSTARS conduct several SETSERIAL (OLD LINUX applet) during the Drivers setup?

How does KSTARS confirm that communication over serial devices is appropriate and a what frequency to clients which are remote?

Thank you.
