I gotta know if any of you have seen this crazy thing before. I was in my garden the other day watering my Chile peppers that i grow and sell, when I spot a spider web right next to my bell pepper patch.

It didn't look like the average kind of web. This thing was covered in this, like, super sticky goo. Not the usual fly-catching kind, this stuff was seriously sticky.

Like, if you brushed against it, it would stick to your clothes. I Googled it and didn't find much information that matched it.

The web looked like pure silk and had colorful spots on it.

I've been diving into the world of amateur satellites, and the idea of building one is absolutely thrilling! However, like any ambitious project, getting started can feel overwhelming. So, I wanted to gather some collective wisdom from this awesome community.

1. Choosing Components: What are the must-have components for a basic satellite? Any recommendations on where to source them without breaking the bank?

2. Learning Resources: What books, online courses, or tutorials have you found invaluable in understanding satellite design and operation?

3. Software and Simulations: Are there any specific software tools or simulation programs you'd suggest for planning and testing satellite systems?

4. Launching: What are the best options for getting a small satellite into orbit for amateurs? Has anyone here collaborated with organizations like SpaceX or Rocket Lab?

5. Success Stories: I'd love to hear about your personal projects! What challenges did you face, and how did you overcome them? Pics and progress updates are always welcome!

Thanks in advance!

What aspect are you most passionate about and why ?

Hey folks, I'm working on a project involving the design of a heat exchanger, and I've hit a bit of a wall. I'm trying to optimize the fin design for maximum thermal efficiency while keeping the pressure drop within acceptable limits. I know the general principles, but I'm struggling with the specifics of selecting the right fin geometry and material.

Any tips or resources you could recommend for tackling this?

Appreciate any advice from those who've been down this road before!
