LM338 Circuit 1,5v…32v – 3A s you know, every electronic circuit needs power. That is why power supplies and voltage stabilizers are one of the most popular topics, enjoying uninterrupted interest. The presented power supply is an application of the popular LM338 regulator IC, which housed practically all elements of the high voltage regulator LM338.…
Mono power module, based on LM3886 application. He enjoys very high popularity and good reputation even among audiophiles who are “overly sensitive to everything that is integrated”. The LM3886 integrated circuit is based on bipolar transistors. It is equipped with protection circuitry for overheating, overload, and a very useful muting circuit for switching on and…
LM2576T-ADJ Power supply DC DC through long cables is associated with the voltage that is the greater, the longer the cable length and the current drawn by the receiver. Sometimes this fall is so big that the receiver is not working properly. The presented regulator compensates for this by measuring the voltage at the receiver…
Nixie lamp Thermometer DS18B20 Circuit with ATtiny2313 The first Nixie lamps appeared in the mid-twentieth century. For many years they have been used in a variety of apparatuses but have been supplanted by newer VFD displays and LEDs. For decades, forgotten again, they returned to grace in retro electronics projects of hobbyists as well as…
TPA3116 Class D Amplifier Circuit A small class-D mid-range stereo headset that will be used in car headphones, active speakers, or PC-audio. The amplifier module is based on the TPA3116 circuit comprising two bridged power amplifier channels with common switching, muting and protection circuits. TPA3116 Circuit schematic The TPA3116 power amplifier schematic diagram. The U1…
The lamp used in the project is PCL805 tube. Older Readers may remember it because it was used in the vertical deflection pattern of most tube TVs. Today it can be obtained for free or almost free because it has not found use in today’s acoustic amplifiers built by many enthusiasts. What parameters does this…
LM4952 It is not always necessary to have a high power audio amplifier. It is enough to power the small speakers with much less power. The presented amplifier meets this condition. It has a power of 2 × 3 W / 4 V, and additionally allows electronic volume control. LM4952 The module is based on…
The L298 is an engine driver with two H-bridges. It can control two DC motors or one bipolar 4-wire stepper motor. Its main advantage is a large power supply voltage range (up to 46V) and high L298 maximum load currents: 2A continuous, 3A instantaneous. In addition, the voltage has been applied to the CON1 connector,…
ATMEGA48 Many devices may be in standby mode during downtime. They do not perform any work, they are apparently disabled, but the control circuits are powered. To extract useful information from the point of view of working time, you should download it from the inside of the device, which may end up with a loss…
Guitar Amplifier circuit the signal is directed to the tip of the TDA2050. The output power is 25 W with a load of 4 ? (17 W at 8 ?). This block is equipped with an additional “CD / MP3 Player” input and three “Slave Out” outputs (for other terminals or recording equipment), “Headphones” (for…
