With mechanical modification and LM324 mosfet motor driver circuit, the battery has expired and the switch has been broken and the rechargeable drill has been converted into an engraving machine…

The motor driver circuit controlled by TL494 PWM IC is 36V 864W and its maximum over-power is 1800W. Lithium-ion (Li-ion) batteries are used for the power supply. Ten cells are..

The password electronic lock circuit PIC16F628A can store up to 128 users’ passwords. Users can change their passwords whenever they want. PIC16F628 and external Eeprom 24c08 are used to store..

A project made for the use of Scrap Laminator as a PCB laminator. The heating resistance control in the cylinder of the laminator is provided by BTA12 triac, LM339 op..

I prepared a PCB for the Simple Switch Mode Power Supply Self Osc ATX Transformer that I shared before. It is compatible with the battery boxes of many drills. Apart..

A simple battery charger using the LM317T three-terminal voltage regulator. The maximum output current of the LM317T integrated circuit, which is 1.2 A, is increased by the power transistor (BD912)…

The aim is to make a simple and at the same time effective device that will count the number of people entering and exiting rooms with a single entrance door…

There are interesting projects but I don’t think most of them will be implemented. For this reason, I touched on PCB, Schematic designs. Especially power electronics studies can be useful..

For the circuit; It is called “Universal power control”. A circuit that reduces the brightness and therefore the power consumption of the energy saving lamp as a night lamp. It..

I did the time test of the Advanced Battery Desulfurizer Circuit circuit that I shared before with a 12V 60A Car battery. I will keep the desulfurizer connected to the..
