I want to learn designing IOT PCBs (with 2.4Ghz wireless) in c/askelectronics@discuss.tchncs.de
[–] ntn888@lemmy.ml 1 points 6 days ago (1 children)

I’m getting 1W 433 modules for like $15 now

haha I guess cheap is relative :) I was considering parts at 4 to 5$ range. But i'm talking about low power ble/zigbee etc..

wow didnt' know that Ebyte modules were that popular! I've come across them in site like lcsc and Ali.. Making use of them is what my current skill level allows. some of the varieties are relatively expensive though..

Okay great! Thanks for all the great insight!

Wow, thank you for the very detailed post! I see that impedance matching is an important base subject. Is it covered in standard circuit theory textbooks. I'm looking to use this book. I tried to skim the contents but couldn't find it... Maybe I need to separately learn it? Thanks.

I see, that reference design suggestion sounds good. And it sounds like there's more practical consideration in tracing/routing on top of the theory.. Thanks for the input!

I want to learn designing IOT PCBs (with 2.4Ghz wireless) (lemmy.ml)
 

Hi all! I'm a firmware developer with little knowledge in analog electronics.. I deal with firmware for IOT projects all the time.

I had to make a breakout board with an off the shelf RF module with self contained PCB antenna. Now I'm intrigued in the hardware side. I'm inclined to design them from scratch myself. (Obviously ignoring the EMI and FCC certifications for the time being).

What concepts should I be familiar with to achieve this? Starting on I figured to brush up on circuit theory and signals. Where do I go from here? What materials would you recommend? Hopefully I don't need to get into hardcore RF theory to design these PCBs (I know kicad already has these premade antenna blocks).

Thank you.

Is Reddit going to remain the primary space for this community? in c/selfhosted@lemmy.world

As much as I like the interface and idea of lemmy, I think the content traffic is not enough for me.. and keep going back to reddit :/

thanks for the info... I'm thinking of sticking with just Debian (as my simple usecase) and use virsh commands..

Okay 👍 Thanks for your suggestions. Think I'll just stick with Debian 🙂

haven't thought about it. I guess I'll learn some bash :)

BTW what is a good OS for the VM host? many here are running proxmox... would you recommend it for this purpose of bash automation to bring up VMs?

Thanks.. Just for clarification, you can use Ansible to control Proxmox as well.. and automate the entire VM bring up?

Hi, I have a home server (basically a NAS) currently running Debian. Basically it's configuration is as follows

  • debian host running 3 VMs

  • debian running inside each VM as docker host

I just manually install KVM on the host then docker on each VM after creating each of them. I documented the process so I know how to replicate it in case I need to rebuild.

I now dream of being able to automate the rebuild process using config files. I know this is done using Ansible.

But I've now heard of Talos.. (A thin layer for kubernetes) and intrigued. But I suppose I need a setup for the VM host to achieve automation through config files..

What setup are you guys using?

Thank you.

Thanks for all your suggestions! I've chosen to go with just bash scripting (given my simple setup) and keep the setup as it is.. Just gotta learn bash and virsh :)

Thanks for the addition. It's also mentioned in that original blog post I linked in the article.

I understand what you mean. It's become a habit of mine lately, and I learn lots in the discussion to.

In my defence I did run some tests and confirm it's functioning.

The minimalism of Jerboa app is unparalleled (lemmy.ml)
 

So I've just found out about Lemmy. (Although I'm a big FOSS enthusiast)

Choose this app for my Android device, and boy nothing beats it's minimalism!

For folks that are unable to port forward on the local router (eg CGNAT) I made this post on doing it via a VPS. I've scoured the internet and didn't find a complete guide.
