Solar powered all sky camera.
cjdawson posted a topic in DIY AstronomerI'm planning a my astronomy project for 2023. This is going to be a solar powered all sky camera based on a Raspberry PI 4 (8Gb model) with a ZWO ASI 462MC camera. I'm thinking about the rest of the bulid, and have decided that the Dewcontrol 12v heater ring should work well. Here's a list of the things that I've been thinking about for this project, so ensure it's success. 1. Controller - Raspberry Pi 4 (8Gb Model) (Already have) 2. Camera - ZWO ASI 462MC with standard lens (Already Have) 3. DewControl 12v dew heater (on order) 4. Relay that will be PI controlled, (Have some already, but likely to order a different one later, I have duel relays, but will only need a single) 5. Temperature and humidity sensors. (want to calculate the dew point and keep the camera dew free) 6. Battery 7. Solar controller (already have one) 8. Solar panels. (have 50w panel, will this be enough) 9. SSD or MicroSD? My plan is to have the camera, PI and heater all run from the battery, and have the battery charged by solar power. For the OS, I know that there's an all sky project on Github that I'll be using for the camera control part of things, that's going to do most of the work. The PI will connect to my home network via Wifi, the build in wifi on the PI should be good enough, especially as it'll be in a plastic enclosure. I'm not sure what size battery I'd need to be able to set this up and leave it running. Most likely a 10Ah 12V battery should do the job? I'm thinking of getter a 12v to USB C adapter to run the PI on. That should provide enough power without worrying about under volting the PI. The real question here is will a 10Ah battery be enough to keep the PI running 24/7, and will a 50W panel be enough to keep the battery alive through the winter? Would be interested in others experiences as it would be helpful in allowing me to come up with a solution that is going to be up to the job.
Single board computer lattepanda
shirva posted a topic in Discussions - EEVA EquipmentBeen getting help from old stash, setting up raspberry pi4 4gb for astronomy,, he had the patience of a Saint, We got there in the end, I used the astroberry operating system put together by radek,, Linux just isn't my thing lol, The astroberry system has software such as k stars/ekos, cdc/ccdciel, oacapture, hnsky an few more,, I tried combinations of the software and found it wasn't what I wanted,, the concept of remote desktop, from a small,, single board computer did interest me for a portable grab n go kit,, I could sit in my car and keep warm and control my kit via WiFi on a laptop Came across the lattepanda,, not much bigger than the raspberry pi 4 4gb, but it's operating system is windows 10. I could have went for the flagship Alpha model,, but the idea was to try the entry level panda and see what could be achieved with it, I bought mine with Windows 10 installed from the pi hut,, £118 and was delivered within two days to Scotland,, The WiFi ariel is not fitted to the board,, but just a push in fit,, not easy when you have hands like shovels. Power was supplied via a phone charger b type plug, it takes full size hdmi cable, and I fitted a Bluetooth dingle to use mini keyboard /touch pad to set it up. This was very easy to do, soon on to downloading Software I wanted to use, CdC, went in no problem, Ascom didn't,, I net frame work was missing,, on the panda windows,, type in,,, enable windows features,, then when next screen appears, tick,, framework box and continue,, windows will search and update the system,, Ascom installed fine after that. Eqmod installed no problem, installed hitecastro dc focuser, easy again,, backyard eos Pro and sharpcap Pro installed OK. This all went pretty easily,, testing,, Got it working my heq5, focuser,, initially tested backyard eos and my Canon 600d,, set up focus control ect. Installed tight vnc and yet Again easily done,, I now had it connected remotely to my laptop via my smartphone hot-spot. Absolutely loving it,, so much easier than setting up the raspberry pi. Next up was testing my zwo asi178 mc on sharpcap Pro,, camera not recognised,, soon pinpointed that the zwo driver was not installed,, downloaded this and the Ascom driver just to be shure I had it,, I also got the asi studio suggested the other day. Tried this out camera connected no problem and worked on remote desktop Sharpcap recognised the camera as well,, working great on remote desktop I installed tight vnc on to my linx 10" Windows tablet,, put in the panda IP address,, I now had a TV plugged into the panda at the mount, a Toshiba laptop and a tablet on remote desktop and both had control over the panda,, absolutely brilliant,, the vnc is also available on android and other os, This would be great for outreach. I've only installed software that I want to use,, internal memory I still have 12 gb free. My next plan is to incorporate this system to my azgti,, problem I found having set up the panda to my laptop via my phone hot-spot,, I could not connect to the azgti mount, it was either,, WiFi or hot spot on the phone,, I tried this using the raspberry pi.. Had a think about it and, I believe the easy solution to my problem is fitting the azgti cable,, I've ordered from FLO, attach this to the panda,, install azgti Ascom driver, then I should be able to control mount with ccdc,,.. Will find out if I'm right in a few days,, should then have a portable kit I can control via remote desktop in my warm car in the winter. Davy
