🧠 Qapla': Training AI on ESP32 microcontroller Qapla' is an open-source project that demonstrates training a transformer model entirely from scratch on an inexpensive ESP32-S3 microcontroller. Instead of running a pre-trained model, it performs the complete training process—including backpropagation and weight updates—directly on the device. Features of the project: ➡️Full on-device transformer training ➡️Handwritten C backpropagation ➡️No pre-trained model required ➡️Open and reproducible setup Qapla' proves that even low-cost microcontrollers can train small transformer models without GPUs or cloud infrastructure. It is an interesting project for embedded AI developers, TinyML enthusiasts, and researchers exploring on-device learning under extreme hardware constraints. ⛓ More information... #projects #esp32 #artificial_intelligence

In order to read more buttons with only one input, you can use an analog #arduino input connecting buttons in a resistive divider. ↪️ Day 31 of sharing my content from my old IG page Update: a tribute to Kavinsky who recently passed away (background music).

If you want to connect a button without using the internal pull-up resistor you can connect a 10kohm resistor between the button and ground (so it's pull-down). Then you can set the code in order to control the LED. ⚡ ↪️ Day 30 of sharing my content from my old IG page Update: don't stop when you make it work.

New diy projects are coming back! 😍 ↪️ Day 28 of sharing my content from my old IG page Update: Arduino Uno must remain as an evergreen for makers. Students, hobbyists and makers who want to learn programming and electronics shouldn't start with the Arduino Uno Q, it is too far from learning a microcontroller! 🙌 I see the Arduino Uno Q as a great way to go deeper once you already have a solid foundation. New tools aren’t something to demonize; they’re opportunities to grow and explore further!! 🔥 °°° °°° °°° Like ❤️, share 📨, save 🔖, follow 👥 DM me for permission to repost ✔️ #arduino #arduinouno #arduinoprojects #arduinoproject #arduinomega

Today I'm back to the normal routine. 📓 The next exam is about digital systems. ⚡ ↪️ Day 26 of sharing my content from my old IG page Update: do you remember quantisation? The Lloyd-Max quantizer (LMQ) is a quantization function that performs minimum mean squared error quantization. Suppose we want to find the best way to quantize a set of (continuous-valued) data to n discrete levels. If the n levels are known (let’s say they are values t1 through tn), then the decision boundaries are at the midpoint between the values. °°° °°° °°° Like ❤️, share 📨, save 🔖, follow 👥 DM me for permission to repost ✔️ #unibo #studentlife #engineering #ingegneria #engineeringlife

Do you really know what EMC is? 📶 There are several phrases commonly repeated in EMC publications and presentations that bother me much more than they probably should. This article explores the following phrases and tries to explain what's wrong with them: 🔹The microprocessor is radiating! 🔹My product is 6 dB(μV/m) over the limit. 🔹Ground is an equipotential surface. 🔹Ground is a path for returning currents to their source. 🔹Ground is a place where carrots and potatoes thrive. 🔹Radiation is proportional to loop area. 🔹Inductance is proportional to loop area. 🔹They don't teach this in the schools ... 🔗 Misleading (but Often-Repeated) EMC Phrases
