The RGB Led version of the Led Heart Circuit Music Box I shared earlier, the RGB LED version of the RGB Led Effect circuit, the PIC12F629 RGB mood light section in the previous circuit was used. There are many working modes in the parallel circuit with 20 5mm RGB LEDs, you can memorize the mode…
The microphone vu meter circuit was normally a classic design with 10, I just rearranged it as a single channel strip led vu meter by using the microphone preamp stage and increasing the output power with 50N06 mosfet IRFZ44, IRF3205 and similar N-channel mosfets can be used instead of 50N06 mosfets used in the LM358…
One of the reasons why the speakers fail is that the amplifier fails and gives DC voltage to the output. The speaker protection circuit detects the DC voltage at the amplifier output and disconnects the speaker. The DC voltage detection level of the protection circuit is very low (0.7…1V) so that the speaker is protected…
I shared many SMPS circuits made with IR2153. IR2153 is especially suitable for use in amplifier power supplies, even in power amplifiers in large companies, in mixers Power supply uses IR2153 on the SMPS floor. (Yamaha EMX5000 mixer service manual ir2153) I have been working on the SMPS circuit I have applied for a long…
The DIY version of the Crown XLS series professional amplifier is tried and tested and is even sold as a kit. There are 300W, 600W, 800W, 1200w versions that have been applied by removing some parts without changing the design of the original circuit much, I prepared a PCB for the 400W version. Crown XLS…
Installing programs on Atmel AVR microcontrollers is officially cruel 🙂 fuse settings are a separate issue, especially when wrong fuse settings lock the processor is a bad situation. There is Atmel AVR Fuse Bit Repair circuit, but we are already unfamiliar with AVR, this job is even worse, if more processors accumulate in the future,…
In Vu meter circuits, the LEDs give light according to the level of the sound signal. In this circuit, the LEDs give light according to certain frequencies (various calculations and PWM control). Led colorful music circuit, dance lights or disco lights project made with ATtiny13 microcontroller. It allows the LEDs to light up according to…
Galvanic isolation for a logic analyzer with 8 channels. Galvanic isolation for Logic Analyzer with 8 channels. Suitable for use up to 2MBit with 2V level and a little faster at higher levels. As always, everything is freely available, including a circuit diagram, board, etching mask and even a Reichelt shopping basket. I have purchased…
I’ve been thinking about making a complete Arcade machine for years. I previously renewed my handmade arcade joystick and Arcade joystick table for the Emulator. I shared the joystick systems I made for the mame emulator in their articles. They worked very well, but they didn’t taste like the original machine, although it is important…
Matlab models of DC DC converters A study on standard DC DC converters with transformers, their applications and simulation results in Matlab Simulink software environment using Simscape library. A large part of the work is devoted to the theory and design of the transformer model, which is an important part of the transformer DC DC…
