IT IS VERY EXPENSIVE ME AND MY FRIENDS ARE ALSO MAKING A CUBESAT

Dinga dinga

That should tell you something about the religion of the region.

Ah yes gotta bring religion ​@@steveadams7550

لا علاقة للدين كل مافي الامر ان اغلب الحكومات العربية تقمع شعوبها وتمنع المفكرين من التفكير ​@@steveadams7550

The religion is pro pursuit of science believe it or not... its often the practitioners of said religions/the conservative law makers who make these stupid laws​@steveadams7550

@steveadams7550 if u mean the government, they re against the religion. Otherwise, no one would face such an issue.

Hi Johnny, I believe you started with the blank PCBs and have ordered parts to build your CubeSatSim, right? If you could post your question on our GitHub Discussion page, we can help you out github.com/alanbjohnston/CubeSatSim/discussions Alan

We will have a limited number at Hamvention 2024 and will also have a few for sale on the AMSAT Store in June.

@@ku2y Can it be shipped to India?

Hi Raz, the longer stacking (1979) headers are attached to the boards. The shorter stacking headers (2223) are used between the boards.

@@ku2y Ok, That's interesting. I used a different stacking header (maybe from amazon), which is shorter than the 1979, but then when stacking the boards I had too large of a gap, even with the push-offs. So I would imagine that I need a shorter stacking header to get the spacing, and not a longer one.

Hi, I like my soldering iron on the hot side, so around 350C. I use blue putty (sometimes known as "blue tak" or "fun tak") such as this: www.amazon.com/Loctite-Fun-Tak-Mounting-2-Ounce-1087306/dp/B001F57ZPW/

I would assume

Yes, the code for the CubeSatSim (a CubeSat Simulator, not a real CubeSat for going to space) is here github.com/alanbjohnston/CubeSatSim

Thanks a lot!

That is true, although there have been successful GPS experiments in space. This is a CubeSat Simulator, a functional model of a CubeSat for the classroom, so it is not designed to go to space but for studying here on earth.

Generally custom

That’s correct. The CubeSatSim has a Pi Zero inside it. Step 2 installs the software for it. This step is setting up the Ground Station that receives the radio signals from CubeSatSim. You can use your own PC for the Ground Station, or you can use another Raspberry Pi such as the Pi 4.

Hi, it is all on GitHub github.com/alanbjohnston/CubeSatSim

This isn't designed for a space mission - it is an educational model for demonstrations and learning. Everything is on GitHub github.com/alanbjohnston/CubeSatSim

Hi Dean, go under the Edit menu then select Preferences then Modules then in the Layout tab, select the Select Layout dropdown then select Map Table Polar and Single Sat (Wide) option. I like this view best, but you can try the other options too. Good luck and 73, Alan

@@ku2y That worked! Thanks!! I did not know about those settings!!!

Thank you!

The Pi 3 works with everything except for the power supply. The 5V boost converter can’t supply enough current. You will either have to power the Pi 3 directly or find an alternative boost converter circuit that will supply enough current.

If your ground station and the CubeSatSim are in the same room, any antenna will likely work. The Pi software also has the gain turned up, too.

Hi! You can find the bill of materials here: cubesatsim.org/bom

No, it’s the sound of the radio telemetry.

​@@ku2y there after you 😂😂😂

it costs a few hundred dollars in parts. the bill of materials is here: cubesatsim.org/bom

it costs a few hundred dollars in parts. the bill of materials is here: cubesatsim.org/bom

The CubeSatSim is designed for the classroom, not space. The range is a few hundred meters.

@@ku2y what would you do to increase the range?

Hi Graham, good luck with your CubeSatSim project! We no longer recommend the purple INA219 boards as they are expensive, hard to find, and have a high failure rate. Instead, look for the blue INA219 boards - they are a little larger, so you have to mount them on sockets or otherwise get creative so they fit. Feel free to share your progress or ask questions on our GitHub Discussion Board github.com/alanbjohnston/CubeSatSim/discussions

Phr software bna leya?

we alsoo need help bro🥲🥺

Hi Konrad, yes this is correct. It is less than 10mW of power.

Hi Devlin, I’d need to see your logs to be sure. It should not reboot each time you change modes. If you share some logs (the output of CubeSatSim/log command on the Pi) on the GitHub Discussion page we can troubleshoot it: github.com/alanbjohnston/CubeSatSim/discussions

He's created an overview and a whole series of RU-vids that detail every part of this project. You just need to binge-watch them, buy the parts and build it!

Hi! The green LED on the Main board comes on when the CubeSatSim software runs on the Pi Zero. If you never see the green LED turn on, it is probably a software problem. When you did Step 2 github.com/alanbjohnston/CubeSatSim/wiki/2.-Software-Install did you write the image or did you do a manual software install? If you log into your Pi, you can check the log by typing: CubeSatSim/log That will tell you if the software is running and if there are any errors. Good luck!

​@@ku2y Thanks for your quick reply. I just checked the log and it turns out the battery voltage was too low, so the system shuted down automatically. Gonna try another set of batteries...

@@enscima2202 When you plug in your USB charging cable, the red Main board LED will light up and the battery voltage will jump up to a value around 4V. You can measure the voltage of the battery pack on the Battery board with the + and - pins. The batteries will fully charge in a few hours.

​@@ku2y I changed a set of batteries and measured a 3.9V on the battery board. When I keep the Pi plugged in the log says the battery voltage is around 3.8V which will not shut down itself. But the CubeSatSim software still does not start(no green light) after I unplugged the Pi. btw it works well with USB cable plugged into the Pi or the main board.

@@enscima2202 You are using a Pi Zero 2, right? On boot, it draws a huge current for a moment, up to 400 mA. This can cause the battery voltage to drop suddenly causing the shutdown. The latest software tries to avoid this. Are you running the latest software? Log into your Pi when it is on your internet and type CubeSatSim/update Or, just note the version number when you type CubeSatSim/config When you plug the USB charger in, do you see a small red LED on the Main board NiMH charger board? Does this LED go off after a few hours of charging?

Hi Graeme, we no longer use the purple INA219 modules. They are hard to find and most of them don’t work. Use the blue ones instead. Due to their larger size, you’ll need to put them on sockets or use headers to raise them up. See the latest BOM: CubeSatSim.org/bom Good luck!

@@ku2y I used the blue one as well. I cut out the PCB corners and sides a bit.

I recommend using the chips on the pcb.

Hi Terry, that's interesting - I've never tried it that way. I usually do it directly using the URL without ever downloading the image file, as they are so huge.
