Looks like a fun tinker project. Could be easily extended with a GPS receiver to show your location on the map.

A SDR could be cool too, and basically let it connect live to ISS when the GPS confirms its above. CPU and memory might be an issue, but getting some 145Mhz / 437Mhz SDR and an external antenna jack on the board could be a cool way of letting the device listen in when the ISS is above.

Definitely alot of directions you could go with it, looking forward to seeing what people do with the code!

Really neat! If you're interested in adding clouds to your basemap I built a service [0] which generates free, almost-live cloudmaps (with alpha channel or precomposited onto a Blue Marble image) as part of my own ISS tracker project

That's really cool! Starred so I can find it later, might be challenging putting it on the esp32 but if there's an easy way to downsize the images then it should be do-able. Thanks!

Wow, this is pretty legendary work: https://iss.matteason.co.uk/

Oh man your work is amazing. Just saw this https://tf230.matteason.co.uk amazing usage of gov.uk design system. They should make this official :D

This is a complete tangent, but a photographer recently captured what is likely the all-time best shot of the ISS.

WOW that is a cool shot, thanks for sharing!

Another variant of the generic:

"Read a REST endpoint via HTTP and draw it on a display with LVGL"

But also funny because OP used two MCUs, when a single ESP32 could do all of this.

keyth72•7mo ago

Yup, that's all it is! Really simple beginner project, with room to grow on the hardware.

you seem to be (someone who wants to appear) more experienced. maybe you could give constructive feedback rather than ridiculing. what a negative comment just to feel better about yourself. sad.

keyth72•7mo ago

No need to perpetuate any negativity, I can take it ;) constructive feedback is appreciated though!

Aaaw, this only displays the position on a screen :( I was hoping for the cool version where a small arm is physically pointing at the ISS.

keyth72•7mo ago

I saw that one! Very impressive project with 3D printed parts. Here is that project for anyone interested: https://projecthub.arduino.cc/alex_chang/satellite-tracker-2...

Or maybe this is the one you meant: https://www.reddit.com/r/arduino/comments/11pxh3h/iss_tracke...

This looks like a fun project. Any reason for using resistive touch model?

keyth72•7mo ago

It's what I learned on, and there seems to be more info available out there about it (for now), but capacitive touch CYD would probably be better/more responsive. The resistive touch option seems to be a few dollars cheaper in general on Amazon.
