    Siren Sound | Bird Sound | Tone generator using 555 timer

    Thanks for sharing. For such projects, I always used ready-made sound modules. I didn't really think it was possible to make one by myself.

    voltage control

    It is always good to make a design and use simulation software. Like proteus. This will give you an idea of how your circuit will behave in real life. Then you can proceed to the hardware implementation.

    Adjustable Low EMI Switching Power Supply

    Thanks a lot. Power supply design always looks challenging to me. Even the ready-made Power supplies like Baku, Koccu etc. fail after a few days. Hopefully, I will follow this design someday.

    Pika Power Board - Powerful, breadboard compatible, easy to use power supply board

    I can see that you directly connected a lightbulb to the board. Is that an AC bulb or DC?

    Home Assistance on Raspberry Pi

    For IoT projects I use the free version of BLYNK 2. Is home assistance free or paid? Does it support only Raspberry Pi or ESP8266/32 also?

    I want to merge Darkness and PIR Motion Sensor into one circuit

    I think it will be much easier if you switch to Arduino. You will need to connect the PIR output to a digital pin. You will also need to conenct the LDR to an analog pin of the Arduino. By using the digitalRead and analogRead functions you can read the PIR and LDR sensor outputs. Then you can...

    DIY Laser Range Finder (1mm Accuracy)

    Great product. Personally, I never used the VL53L0X sensor. But I find it very interesting and useful. The PCB looks neat too. Did you get the PCB from https://www.pcbway.com ?  Or somewhere else?

    A guide to LED Emergency Light Circuit with LDR

    Very simple but useful project. I was just wondering, have you made any PCB of this project? You can make a prototype by yourself or get it printed from:  https://www.pcbway.com

    Lattepanda alternative

    Hello, I am interested in Machine learning projects nowadays. This shopping cart looks very cool to me. https://www.pcbway.com/project/shareproject/IoT_AI_driven_Smart_Grocery_Cart_w_Edge_Impulse_5652a9b2.html I can see a Lattepanda has been used here. I wanna know if it is possible to use...

    voltage control

    Hi, have you tested it by yourself?

    unknown PWM controller

    I think you are right. Because I never came across such a strange marking on ICs before.

    👉 35V-5A Adjustable Switching Power Supply (DC to DC Buck Converter)

    Thanks for sharing the design and the video. I came across this design and found it good too:  https://www.pcbway.com/project/shareproject/power_supply_0_30V_2mA_3A_version2_28ca8ff0.html But your power supply has a bigger voltage and current rating I can see.

    Help needed

    The LEDs are 12V LEDs, right? If you use a 9V battery, I think the LEDs will not turn on properly. You may just see a faint glow.

    I just do a design of lm386-based audio amplifier circuit

    Good to know that you got it working.
