My First Dance with ESP32, IDF, and FreeRTOS: From Blinking Lights to Talking Tasks

For a while now, I've been happily living in the Arduino world. setup() , loop() , a few libraries, and you've got a working project. It's fantastic for getting ideas off the ground quickly. But I kept hearing whispers of something more powerful, more professional: the ESP-IDF (Espressif IoT Development Framework) and its built-in operating system, FreeRTOS . The promise was tantalizing: true multitasking, better control over the hardware, and the ability to build really complex, robust applications. So, I decided to take the plunge. Here's a raw look at my first few steps into this new and slightly intimidating world. With FreeRTOS, the fundamental concept changes. You don't just have one big loop() . Instead, you have Tasks —independent, concurrent functions that the OS schedules to run. It's like having multiple loop() functions running at the same time. My goal was simple: create one task dedicated solely to blinking an LED. Here’s what my first piece of r...

Bring It Home: Why We Chose to Manufacture Our Circuits In-House

Image
In the world of electronics, outsourcing manufacturing has become the default for many. The logic seems simple: find a partner, send them your designs, and let them handle the complex process of fabrication and assembly. We've all heard the stories of cost savings and scalability. But what if I told you that for us, the most strategic move was to bring it all back home? Deciding to manufacture our own electronic circuits in-house wasn't a decision we took lightly. It was a calculated choice based on a simple principle: control. Here’s a look at why taking the road less traveled has made all the difference for our products and our business. Unparalleled Quality Control ✅ When you outsource, you're placing your product's quality in someone else's hands. While many overseas partners do fantastic work, there's always a degree of separation. Inspections happen miles away, and communication can be delayed by time zones. By manufacturing in-house, we have our eyes on t...

PWM based Solar Battery Charger Development

Image
Hello, I was procrastinating this project for very long time but now got some time to work on it. It is solar charge controller rated for 12V battery and Max charging current is 10Amp. Controller using in it is Megawin MG82F6D17 8051 based MCU. I am using it because of 12Bit ADC for more accurate voltage reading and it's built-in PCA for PWM generation. Charging methodology is CCCV. For Bulk mode battery will be charged in Constant Current Mode and when it reaches the certain level controller switches to Float mode where tickle charge current is to keep it charged.

Developing Panipuri Water Vending Machine Controller

Image
 Panipuri water vending machine controller is new product I am working actively, The water will dispense when proximity sensor is triggered and chutney mixed water must keep mixing so that solid particles in water does not settled down to bottom which dilutes the tase of panipuri water. So I designed a circuit with 2 MOSET outputs one is for Vending The Water and another for Mixing The Water, system operates on 12V DC and has +5V Regulator onboard for Microcontroller and Proximity Sensor.  Real challenge was to develop it on cheapest microcontroller to put cap on final pricing, also the controller must have EEPROM to store some parameters. Controller has 2 Buttons to adjust Dispensing Quantity which is proportional to Time, and Pressure of Dispensing Motor which I achieve using PWM Duty Control based MOSFET Driving. These settings are kept in EEPROM and Recall after every power-up. PCB is double Side PTH as it is very smaller and have some SMD Components. It Cost around 35 IN...

New Product Development Automatic Incubator Controller

 Hello Folks, I am currently working on a Automatic Incubator Controller for egg hatching, it involves the precise control of temperature and humidity over the hatching period of 21 days. The temperature and humidity setpoints are also related to the day of hatching like 1-6 days is different then gradually decrease as days pass. In a project I have implemented PID control loop and it is auto tuning function so that temperature control curve does not overshoot. Also there is function of egg rotation on regular basis to avoid embryo sticking to the egg shell. Here is time laps of temperature control over the time with adaptive setpoints changing automatically.
