Because 3 weeks of clouds it was time to do something else.
I worked on a "Cordwrap Free" EAA setup that can also be used "in the field" without an existing local WiFi network.
This setup was mainly inspired by the CN forum contributions. A big thank to everyone sharing their knowledge.
6 SE / Evolution 8 + StarSense (same unit switched between both scopes)
Mini PC KODLIX ('Beelink') AP42 with Intel Apollo Lake N 2.5 GHz
Windows 10 Home
WiFi with external antenna (2.4/5.8 G)
3 x USB 3.1 ports
DDR3 4 GB - eMMC 57.5 GB - SDXCI 128 GB
Supply: 12V/1A DC
MAXOAK K2 50.000 mAh PowerBank (57 Wh at 12 V)
1x 20V/3A + 1x 12V/2.5A + 2x USB 5V/1A + 2x USB 5V/2.1A
Access Point Mode at laptop with "Connectify" software.
TP-Link AC1200 Dualband WLAN Repeater RE305 with 2 external antennas.
Located in between laptop (inside) and scope.
12 V DC splitter cable
The PowerBank supplies the:
- KODLIX AP42
- scope 6 SE
(the Evo 8 uses his own Li-Ion battery, but can be supplied when necessary)
- Hi-Tec Astro Dew Heater Controller (Dew Strip)
Because this controller has a cigarette lighter supply, I had to use a 'DC-to-female' cigarette lighter adapter cable.
Could be simplified by DIY soldering...
- ATIK Infinity (other cameras supplied by USB)
The Powerbank is attached at the back of the mount arm with velcro.
The KODLIX is attached to the Powerbank with velcro.
I can easily switch this assembly between the 6 SE and the Evolution 8.
The KODLIX comes with a claen Windows Home installation, without any third party apps!
Some tuning can be done:
- Windows update cleanup (Settings>System>Storage>c:\Temp.Files>Previous versions of Windows)
- UNinstall needless Windows apps
- Windows Defender switched off.
Otherwise the "SearchUI.exe" process tries to establish virus definition updates via WiFi,
which doesn't succeed because their isn't a internet connection.
This process may consume up to 50 % CPU!
- Switched off 'Windows Indexing Service'
- WiFi set as 'metered' so no auto Windows updates
Following additional software installed:
I compared this remote tool with both 'TeamViewer' & 'AnyDesk', and found RDPWrap the most efficient one.
Leave other 2 remote installations in case RDPWrap fails to connect.
- ASCOM Platform 6.3 using POTH Hub
- Stellarium, TheSkyX Pro, Skytools Pro, AstroPlanner
- StarLight Live, SharpCap Pro, Infinity, FireCapture
- Camera drivers
- 'Astrometry.net Local Server' & 'All Sky Plate Solver' installed on SDXC card (runs via symbolic link)
With full dew heater supply their was still 1/4 of the PowerBank capacity left after a 5 hour session.
Normally 1/2 dew heater supply is sufficient, so at least a 8h session should be possible with the Evolution 8.
Still need to test with the 6 SE but don't expect problems.
I will post later some pictures of the setup.
