Adjustable Soldering Iron Circuit 24V 48W
In the analog soldering station project, a “K” type thermocouple was used for temperature measurement. With the adjustable soldering iron circuit, Quick, Solomon and Gordak brand soldering irons were tested for 48 hours and excellent results were obtained in terms of operating safety and maintaining the set temperature. A 24VAC 60W transformer is used for…
Solar Powered 12V Backup System Solar Charge Controller
The 40 watt panel with solar energy system has been used for years and has never caused any problems. A simple circuit made with LM393 integrated circuit is used for battery charging and solar charge regulator. The battery used in solar energy system is called deep cycle or leisure battery. It can handle over-discharging compared…
TL494 DC CDI Ignition Circuit AT-ATX Transformer
For most people interested in capacitor discharge ignition, the repeatability of DC-CDI is difficult and they have little experience with winding transformers. This design uses an AT-ATX PC power supply transformer for voltage conversion. There is no need to wind the transformer. The necessary transformer can be obtained from old-style PC power supplies. TL494 or…
IR2110 IR2153 Ultrasonic Welding Machine Circuit
I don’t know about ultrasonic welding for plastic, but there are projects that can be useful for those who are interested. The appropriate ultrasonic with sufficient power in the application is 60W at 68kHz, disassembled from an ultrasonic cleaner. A lower frequency is more suitable. PVC welding The ultrasonic transducer behaves approximately like a series…
ATX Transformer Simple Switch Mode Power Supply Self Osc SMPS V2
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 from the PCB design, the tests were very challenging, I encountered interesting problems and saw strange events especially in electronics repair work. The problem of…
50AH Battery Charger LM317
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 maximum output current of the charger is limited to approximately 5.3 A by the R4 resistor. Since there was no 0.55-OHM ready-made stone resistor,…
Dimmer Circuit with Mosfet for Energy-Saving Lamps
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 is not recommended to use simple dimmer circuits to change the brightness of these lamps. In the electronic ballast circuits used in energy saving lamps,…
12V 60AH Car Battery Repair Desulfator Test
Advanced Battery Repair Circuit Desulphator
A more powerful and advanced automatic Battery desulfurizer circuit as an alternative to the “Battery Repair Desulfurator Circuit” project. The circuit is used to dissolve the sulfate on the battery plates. If you ask what the desulphator feature is, it is stronger than other circuits, has high, low voltage and overheating protection and can be…
