How (not) to design a Sun Sensor - $1K CubeSat - Part 12

In today's video I discuss the Sun Sensor that I've prototyped for my $1K Cubesat. It is cheap and easy to build -- but watch the video to find out how well it works!

This what I have been waiting for all week

I liked the subtle “subscribe” as you were panning the boards. Nice.

[benkarstenjones]

Definitely my most anticipated series! Amazing work

[remaahmid]

Keep up the good work! Learning a lot from this

[jumpingPeter]

amazing i clicked the notification button so i get notified when u have the next part. Thanks

[przemas]

Great video! I'm looking forward to the next one

[StrawPietro]

Great video as always! Looking forward to the rest, keep it up!

[jamyjamy]

Ooh what a great video i was waiting for the whole time thank u professor

How are you gonna launch your cube sat

[zilvanilab]

are you actually going to launch this. btw i love this series

The algorithm for evaluating a quad detector with an illuminating spot size less than the detector size is well-known. You should be able to get OK results using a series of different size apertures which fit over the detectors.

Maybe its not possible, but have you thought of monitoring the solar panel outputs for each side and using that data to provide Sun orientation?

[weirdeye]

Take the cube element of the satellite itself as the base. Mount photodiodes across all axes. (Fiber cable connection maybe 🤔)

[tonybelu]

Would a camera work as a sensor, or would that require too much computing power? It's essentially a 2D sensor array.

Hey man nice job but how do you plan on communicating with earth ??

[respawnpoint]

If solar panels are present on all six faces of the cubesat, couldn't you use their inputs to determine the basic orientation, then have a smaller sensor that can cover only a smallish arc? If sunlight strikes only one face of the cubesat, that face is already pretty close to aimed at the sun, which would make the sun sensor batter able to focus on the smaller arc, thus presenting higher possible resolution without having to use more expensive photo sensors?

Assuming the solar panels have a wide enough arc to do this, it might also make sense to have a small number of solar cells on five faces, with the final face having the sunlight sensor and being otherwise covered in panels.

Hey I am new to this channel and I’m a bit confused about the project. By the end of it, would you have built a fully operational cubesat that can be sent into orbit or is it just planning that is being done?

[scienceseconds]

Hi Sir how communicate with satellite and ground station which method was using in this satellite please tell me sir how communicate with a 500 km please help me

[markyichen]

Hey dude.. can you make a video upon the radio, receiver, transmitter...etc.. a video upon the communication system.. I also want to launch my own satellite into medium earth orbit (MEO) and moreover I will also want the communication system in the cubesat to send high resolution images from the telescope+dslr that I will add in cubesat..😁. Please make a explained video upon that 🙏 pls pls🙏🙏

can i use mobile phone flashlight as a source
