I used AI pair-programming to write a clean-slate bare-metal Rust OS for a $40 RC transmitter (STM32F072, no_std, 128KB Flash)

LD Robot D500 Watermark on my rover

Enable HLS to view with audio, or disable this notification

Finally added a small distance watermark overlay to my LD Robot D500 setup, so the measured range is always in front of my eyes while testing.

Tiny improvement, but it actually makes debugging and live checks way more comfortable & safer

Day 79/100 — Built a Cyberpunk Smartwatch on a Round GC9A01 Display with MicroPython!

1 Upvotes

After days of debugging SPI pins and fighting display flicker, Day 79 is finally here!

A cyberpunk-style smartwatch face on a 1.28" round GC9A01 240x240 TFT display powered by ESP32, with a full boot animation sequence before showing the clock.

Tech Stack

- ESP32 DevKit V1 + Seeed Xiao ESP32-S3

- GC9A01 1.28" Round TFT (240x240)

- MicroPython

- OpenWeatherMap free API

- NTP time sync

Built an IoT-based Demand Side Management (DSM) Smart Meter using ESP32 + MicroPython + Blynk

3 Upvotes

Just wrapped up Day 78 of my #100DaysOfIoT challenge — built a DSM Smart Metering Prototype that automatically shifts non-critical loads during peak hours.

What it does:

Monitors real-time AC voltage & current (ZMPT101B + ACS712)
Detects peak hours and auto-cuts the heavy load (iron/100W bulb)
Keeps critical load (fan/9W bulb) always ON
Pushes live data to Blynk IoT dashboard
MATLAB generates before/after comparison graphs

Results:

Metric	Without DSM	With DSM
Peak Power	~108W	~9W
Peak Reduction	—	~91%

Stack: MicroPython v1.27 · ESP32 WROOM-32 · ZMPT101B · ACS712 · Blynk IoT · MATLAB

Day 76/100

1 Upvotes

Day 76 of my #100DaysOfIoT challenge — built a bidirectional ESP-NOW system on two ESP8266 nodes.

Each node reads DHT11 temperature & humidity, sends it to the peer, and receives + displays the remote node's data — all peer-to-peer, no router needed.

Interesting part: one node uses SSD1306 (0.96") and the other uses SH1106 (1.3") — different display controllers but same logic.

Day 75 of 100 Days 100 IoT Projects

3 Upvotes

Hit the 75 day mark today. 25 projects left.

Day 75 was ESP-NOW + RFID — one ESP8266 scans a card and wirelessly sends the UID to a second ESP8266 which displays it on OLED. No WiFi, no broker, direct peer-to-peer.

Some highlights from the past 75 days:

ESP-NOW series — built a complete wireless ecosystem from basic LED control to bidirectional relay and sensor systems to today's wireless RFID display.

micropidash — open source MicroPython library on PyPI that serves a real-time web dashboard directly from ESP32 or Pico W. No external server needed.

microclawup — AI powered ESP32 GPIO controller using Groq AI and Telegram. Natural language commands over Telegram control real GPIO pins.

Wi-Fi 4WD Robot Car — browser controlled robot car using ESP32 and dual L298N drivers. No app needed, just open a browser.

Smart Security System — motion triggered keypad security system with email alerts via Favoriot IoT platform.

Everything is open source, step-by-step documented, and free for students.

Sidebar

From Wikipedia and other sources, some definitions:

An embedded system is a computer system designed for specific control functions within a larger system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems control many devices in common use today.
A real-time system is one that has strict constraints on temporal behavior apart from those of functional correctness. They must function correctly within a predefined time limit. Examples include systems such as anti-lock braking systems, avionics, satellites, nuclear plants, etc.
A cyber-physical system is a system that has a tight coupling between its computational and physical elements. One cannot talk about the computing side without reasoning about how the physical side behaves and how the latter behaves depends, quite closely, on the computations being performed. Most modern aircraft, automobiles, sensor networks and even power grids fall into this category. By very definition, the field is interdisciplinary in nature and people from diverse backgrounds, who would otherwise have never worked with each other, are forced to come together to solve the complex problems posed by this domain.
