Hey! Welcome, if you look at our RTOS sessions you should be able to do this check out Engineering hour sessions on FreeRTOS they should translate to ESP32 since it is based on that, shout if you need a hand.

Hi @Rushi , welcome to the server! We'd love to hear a bit about you and what you're working on in embedded systems and RTOS. Feel free to ask any technical questions if you have them. Have a great day!

Hi @Event Pings,
If you attended today's session on FreeRTOS and TF Lite for gesture recognition, the Github repo of the example project had been set to private but is now public. You can find it here: https://github.com/DevHeadsCommunity/gestures-with-freeRTOS.

Salih Brother•11/10/24, 10:40 PM

Thank you @techielew let me explain that.. We engineers and developers often work on multiple hardware and software projects within a small space.. Especially while rents are going higher and higher.. Our workspace is filled with numerous interconnected electronic boards and cables, which can quickly turn into a chaotic environment. In this chaos, a short circuit or a loose connection can cost us days of valuable time.. So, around 2 years ago, as we were struggling with problems in our small and chaotic workspace, we started searching for a solution that could organize our electronic work environment. We created metal plates and magnetic holders, attaching all our project components—electronic circuits, sensors, and cables—to these plates. As a result, the errors we previously encountered were eliminated, and we began working in a highly organized manner.

We even found a way to hang our projects on the walls of our workspace. Later, we designed racks for these metal plates, allowing us to store 6-8 projects within them. This made it easy to take a project from the wall or rack, place it on our desk, and switch it out for a new one when needed. Thanks to this system, we went from being able to work on 1-2 chaotic projects in a small space to efficiently handling 8-10 organized projects in the same area. Carrying and demonstrating the projects became much more easier and professional-looking.

We further developed this product family, converted it into an ecosystem and named it ProBUDDY Kits. Now it has 50+ items covering many types of holders, baseplates, stands, racks, electronics to 3d printable files.. Now it became so helpful for almost any project, any scenario

ke7c2mi•11/10/24, 11:17 PM

This speaks direcly to me and I am eyeing the kickstarter ... I currently have several boards strewn in the space under my monitor. I was thinking to get some copper clad board and drill it with standoffs to tidy things up for just that project.

I've always wanted some sort of rack I could keep a set of shelves in and put one on my desk when I needed it (i.e. the shelves come out of the rack to sit on the desk)

But it looks like you have nailed the concept and made it slick

Umesh Lokhande•11/11/24, 6:15 AM

I feel the best way to start is by experimenting with the ESP32 Dev Kit with Arduino API and IDE to get comfortable with the features it offers. Then, later, you can migrate to the ESP-IDF Framework to get the most out of the ESP mcu for your project. You can use free YouTube video resources, and feel free to ask specific questions here. The community will be happy to help you. Best wishes for your learning journey!

Ttechielew Are the 3D files open and available somewhere to check out?

Salih Brother•11/11/24, 7:33 AM

The 3D designs are created to hold various elements that can be used in projects and are prepared to be compatible with ProBUDDY Kits. The website sundayrobotics.com will be online in few days, If anyone from this forum wants to purchase our products, I can offer additional consultancy and extra discounts to better identify their needs. Would this be appropriate?

Ssegfaultdev.elf or anyone can suggest me good Multimeter in $100 range

JeremyCook•11/11/24, 2:25 PM

Hello, yes I do have some thoughts, as @techielew notes. I did a review of the OWON HDS2102S meter/scope/signal generator some time ago: https://embeddedcomputing.com/technology/debug-and-test/oscilloscopes-analyzers-generators/owon-hds2102s-250-handheld-scope-review

which is in the $250 range. I still use it quite a bit, and like it, though on the negative side there is a delay with some measurements, and I really don't use the signal generator function. Also the battery life isn't great.

hat being said, you can find what looks like the same style of meter/scope on Amazon: https://amzn.to/3AoxfIM (affiliate) for just over $100, with what looks like (at a quick glance) reduced specs compared to what I have. I also have a Fluke 179 that has worked for roughly 2 decades, has excellent battery life, and takes measurements quickly. Looks like they are more expensive, but I guess you get what you pay for.

OWON HDS2102S: ~$250 Handheld Scope Review - Embedded Computing Design

Depending on your level of electronics knowledge, work, and/or experimentation, a voltmeter may be sufficient for your diagnostic needs. However, being able to see the way an electronic signal changes over time, or perhaps even multiple signals, takes your analysis capabilities to a whole new level.

Hi, I am a full stack developer, I work with frontend, backend, mobile, databases to cloud servers.
I'm currently working on a project where I require a big enough RFID reader to detect RFID cutlery embedded plates. Not sure what type of RFID reader I would need. Am here to learn about RFID in general and also find the information I need.

you likely need UHF RFID you can use that to do inventory as you describe

you would need an antennna a reader and some tags to be read and written to, the standard is defined so you can buy off the shelf hardware and software or do it yourself.

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

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

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

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.
