Dear Oscar., I hope you're doing great! I just wanted to share with you some of the things I've been doing and my plans for the near future. Recently, I started building a remote-controlled car using radio frequency modules and recycled materials. It's been a challenging and exciting experience, and I'm learning a lot through trial and error. I've also been thinking about setting up a small workshop to continue working on electronics and possibly teach others who are interested. Technology is amazing, but I've realized how important it is to use it wisely and responsibly, something I've been thinking about a lot lately. It would be great to hear what you've been working on too. Maybe soon we can get together and build something cool, just like old times. Take care, and we'll talk to you soon, Luis.
