oh yes it would it can work in the order of meters.

Ttechielew @Event Pings, This week's Office Hours meetup topic is: https://discord.gg/cHNGv...

ZacckOsiemoOP•11/12/24, 3:21 AM

anyone tried using write protection features on STM32?

ZZacckOsiemo oh yes it would it can work in the order of meters.

fei•11/12/24, 3:39 AM

Oh great, thanks Zacc. Will try this first

fei•11/12/24, 3:42 AM

Hopefully will see if it can focus on the red area from underneath the table

Ffei Hopefully will see if it can focus on the red area from underneath the table

ZacckOsiemoOP•11/12/24, 3:47 AM

the red area is small UHF can cover a small room so it will cover that

Ffei Oh great, thanks Zacc. Will try this first

ZacckOsiemoOP•11/12/24, 3:48 AM

start with a white paper like this https://rainrfid.org/what-is-rain-rfid/ then start breaking out system components and such.

let us know if you get stuck, and once antennas give you issues, we have some people obsessed with beams

ZacckOsiemoOP•11/12/24, 5:08 AM

good idea what are you ordering readers and antennas?

ZacckOsiemoOP•11/12/24, 5:09 AM

that's a good strategy, my first foray into this, being a software developer was to make it myself, boy did I mess up

ZZacckOsiemo good idea what are you ordering readers and antennas?

fei•11/12/24, 6:09 AM

For now only the reader but from what u are implying seems like because i need to use the antennas to direct and shape the signal to the designated area from under the table

fei•11/12/24, 6:09 AM

ill need to check with the supplier

fei•11/12/24, 6:10 AM

yea, i also started from E&E but I started work as a fullstack engineer

, and now after having more experience in software development, trying to go back to my roots since with the advent of AI it seems like its kinda the way

Ffei For now only the reader but from what u are implying seems like because i need t...

ZacckOsiemoOP•11/12/24, 6:11 AM

yes and take care to ensure your reader and antenna have compatible connection points. You may also be operating at such a small range that an internal antenna may work ask about that as well.

ZacckOsiemoOP•11/12/24, 6:12 AM

ahh thats insightful, will keep that in mind while reading more

ZacckOsiemoOP•11/12/24, 6:13 AM

yeah all these are the things that messed me up

fei•11/12/24, 6:14 AM

was afraid of these mishaps, these tips could hopefully save me the trip down that rabbit hole

Hey Vini, not the exact combination but feel free to post questions. You can expect some help with Node-RED and Modbus

could you please share the node flow you designed to extract the variable value. Provide more info. about the things you have done or tried so far.

Umesh Lokhande•11/12/24, 4:04 PM

I'm not sure what exact data and in what format you're getting from Modebus. I hope you've created custom the function to properly store data in the correct format before you print on the node-red debug console.

Hello good people

,

My name is Abdul, I was invited to this server by @32bitSaviour. I'm into everything web and work as a full-stack engineer. I'm super passionate about tech mentorship and volunteer at a non-profit called KamiLimu that aims to upskill university students. I am also very curious about open source. I haven't had the chance to contribute to it in a meaningful way but it is one of my short term goals at the moment.

ZacckOsiemoOP•11/13/24, 7:01 PM

Mambo! do you dabble in any embedded, IOT or electronics work? We would like to hear more about any of that

bijuice•11/13/24, 7:05 PM

No I do not but I would wanna try getting into low level programming. I feel like it's a part of my skillset that I could improve

@Ming @Phoenix, anyone else interested in helping us build out infrastructure to remote into platforms for dev purposes? The idea would be to create something that allows attendees of events apply the learnings on a remote node.

Me, @ke7c2mi and @ZacckOsiemo met yesterday to outline the general concept and are looknig for volunteers to help. If you are interested either like this, reply, or DM me.

Thx
