Bought new DSO for specifically PWM and Power Supply Design Works

Hello techie's, I just bought Fnirsi oscilloscope (DSO), 
It has Function Generator in it too..
FNIRSI 1014D is a 100 MHz bandwidth dual-channel oscilloscope with a built-in waveform generator. The oscilloscope features a high real-time sampling rate of 1 GS/s, 240 kB memory, a large 7-inch display with 800 × 480 resolution, and advanced features for capturing, analyzing, and recording measurement results. Besides, the device features high voltage protection, which ensures safe operation with signals up to 400 V. Built-in function generator generates 14 types of signals, voltage resolution is 8 bit, voltage 5 Vpeak-peak. FNIRSI 1014D is equipped with a USB interface to connect to the computer. This oscilloscope is designed for diagnostics and tuning of radio and electronic equipment.

Compact and functional oscilloscope.
Large 7-inch TFT display (800 × 480 pixels).
High voltage protection: built-in module provides protection up to 400 V.
Built-in 1 GB storage space, can store up to 1000 screenshots + 1000 sets of waveform data.
Automatic measurement function.
Roll function.
Lissajous figures graphic display function.
Screen brightness adjustment function.
Includes: 2 X 100 Mhz Probes, Power Adaptor, USB Cable, Manual

It is powered by 5V 1Amp usb adapter same as mobile charger, also it is comparatively lightweight.. I will post about test results and my experience with it in upcoming posts

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.
