Is a momentary push button ever used as a toggle switch in an industrial system?
I'm designing my own home alarm system at the moment and just noticed that domestic alarm panels often use a single momentary push button (typically '#') for both arming and disarming the system. It generates a generic button press event and the resulting action (arm or disarm) depends on the curren…
Is this Master, slave - Voltage/ current modulation communication approach viable in phantom mode
I’m planning a simple phantom communication system where the same two wires provide voltage and current modulation for Master slave communication. My idea is: - Master → Slave: voltage modulation — 9 V and 12 V represent 1 and 0. - Slave → Master: current/load modulation — approximately 45 mA and 50…
Tinkersteam: A Local Edge Impulse Alternative for RISC-V MCUs
So, continuing along with my Rovari ecosystem for RISC-V one of the things I included was a local alternative to Edge Impulse that would work with RISC-V MCUs, especially since Qualcomm acquired Edge Impulse. I wanted something that would be free to use and that won't require any accounts or cloud o…

Do you have to do operating systems related coding in your job?
I always figured embedded systems was just about coding/controlling peripherals but I see a lot of job descriptions that require some knowledge on startup sequences and such. So, I was wondering how much of OS concepts you use in your day to day job.....and if I'm cooked if I don't have experience w…
STM32G474RE sometimes sends missing data over USB CDC
I am currently in the early stage of creating an oscilloscope, right now I have an ADC configured to sample on each timer interrupt and do DMA transfers. the DMA buffer is 200, 2 byte elements, and I am sending it over USB CDC in a single freeRTOS task that doesnt yield or anything and only gets int…
What is this connector? Is there an associated communication standard likely associated with it? Or is it likely proprietary?

OpenAI is showcasing KiCad integration with their latest model GPT‑6 Astra
I came across an interesting article about benchmarking AI models for circuit design (worth a read as well) where I learned OpenAI is showing Kicad integration with their latest model. I've been skeptical there was enough high quality data they could train them to do a good enough job, but the video…
Are you satisfied with LLMs code quality in embedded software domain?
Hey people, I want to get some opinions on this topic cause I am tired of YouTubers one-shoting slop games and calling new model “crazy good” and what not. I’ve been improving my agentic workflow for the past 2 month, even creating skills tailored to MCU firmware dev, but I am still not satisfied wi…
Environmental Sensor with 7 years battery life
I want to share my latest project, it is an environmental sensor which broadcast environmental measurements over BLE every 5 minutes using a single coin cell battery, while consuming only 1.8 µA in sleep mode and an average current consumption of 15.5 µA. The device measures the room temperature, ai…
AI burn out - how are you dealing with this?
Hi folks! I am absolutely burned out due to AI right now. Everyone on the MT is 'pushing' to use AI for everything and more and more it feels like my profession and know-how is getting devalued, it took me a long time to learn and become proficient on Embedded, I love it, it was my hobby and then my…
