How to make simplest possible autorange Capacitance meter
Pavleski May 25,2024
 The capacity measurement option is usually only available in more expensive multimeters, so it is desirable to make such an instrument ourselves, especially if it is very simple to make and inexpensive. Exactly these conditions are fulfilled in the instrument described below. The measured value is displayed on a large readable display, and its measuring range is from 1 pF to 99 µF which are actually the most frequently used values.  The fact that only two components are...

Smart Modular RGBW Aquarium Lamp With Cloud Remote Monitoring
. May 23,2024
The idea of a RGBW lamp for aquariums stems from the idea of having an open-source lamp, which has the characteristics of being highly feature-rich due to its open-source hardware and software but at the same time easily repairable or interchangeable due to its modularity at very low cost. The lamp can be controlled via Bluetooth via your smartphone and allows you to manage the light intensity separately, so that you can have the lighting effect you like best a...

Arduino-based development board with extra features
silicioslab May 18,2024
IntroductionArduino is an excellent tool for anyone who wants to develop prototypes. The board has all the necessary resources for you to connect numerous electronic elements, modules and sensors.However, there is a big problem that makes connecting these devices difficult: the small number of pins for power supply for +5V and GND. This makes connections difficult, as it requires users to connect several wires together and often creates problems with poor contact between connections.Based on thi...

All About IC UNL2003
Adhikari May 17,2024
The UNL2003 IC contains 7 High Voltage, High Current NPN Darlington Transistor Arrays each rated at 50V, 500mA in a 16-pin DIP package. You can connect the IC directly to a digital logic (like Arduino or Raspberry Pi, TTL or 5V CMOS device) without an external dropping resistor. This IC features "common-cathode flyback diodes" for switching inductive loads. The ULN2003 is known for its high current and high voltage capacity.The Darlington pairs can be "paralleled" for higher current Output.The i...

How to turn mini Tesla Coil from Aliexpress into a Real Powerful SSTC with big spark
Pavleski May 16,2024
 Some time ago I bought a mini tesla coil kit from an online store that cost less than $4. It's a very simple project that I made in a very short time and immediately after switching it on it worked correctly. If I bring a compact fluorescent lamp (CFL) closer to a certain distance, it lights up under the influence of the electric field generated by the device. However, even at the maximum recommended voltage of 24 volts, the length of the spark is not greater than 1-2 millimeters. in ...
