TDA2005 is a classic integrated circuit that achieves great things with low voltage. You can use it as a stereo or bridge depending on its location. It does not hesitate to protect itself in high temperatures and short circuit situations. In this study, we did a sweaty bridge connection study with him. Although it is…
The SMPS Transformer tester is an inexpensive and effective way to test any high Q inductive component. The flyback is particularly useful for performing a quick check on line output transformers and other high frequency wound components such as bias yoke windings and SMPS transformers. Various measurements have shown that SMPS transformers can detect at…
It is stated that the circuit of the device developed for the treatment of stuttering was developed by chance and emerged with the suggestion of a person who had a stuttering problem and managed to eliminate it. The amplifier works problematically due to the wrong value of a capacitor in the circuit. It makes a…
The latest, packaged version of the calculation programs shared in the articles Advanced SMPS Transformer Design Program ExcellentIT and SMPS Converter Coil Transformer Calculation Programs has been updated for about 13 years, and the author has made a great effort. Unfortunately @Starichok master stopped developing. I had to use the Excellent IT 9.1 version, but…
3D drawings of the old generation Ni-MH Battery Drills and the new generation Lion battery used drills with battery pack and box and holder apparatus Battery holders have .stl files for 3D printer. Battery converter 3D drawing printed on the stand from ABS, 1.2 mm thick and 30% filled. After printing, it was dipped in…
Model files for the power supply set in the Proteus electronic simulation program (PROTEUS variable dc source). There are two models of Proteus Variable Power Supply. Variable voltage source controlled by a dial. Proteus Adjustable Current limiting Linear Power Supply Proteus Adjustable Power Supply Library Requirements for the model to work: The model’s .dll file…
Battery balancer circuit is designed to control the charge thresholds of LifePO4 and Li-ion batteries. You can use it on Li-ion and LifePO4 batteries by changing 2 resistor values on the balancer. By adding transistor T1 and resistor R5 to the circuit, it was possible to convert TL431 into a Schmitt trigger. The divider R3,…
Classic analog ESR meter is a circuit based on SN74HC14N integrated circuit, it mainly consists of 150Khz oscillator, buffer, comparator and rectifier amplifier. The maximum range is approximately 75 Ohms and values below 1 ohm will cause some difficulty in reading the position of the galvanometer pointer due to the area used on the scale…
The circuit is a two-stage amplifier with the output transistor operating in linear A mode with a quiescent current of approximately 180 mA. The entire amplifier consists of OOS circuit (elements C5, R5, R6). The resistances of resistors R5 and R6 determine the gain of the node. The output transistor must be mounted on a…
