The following diagram is an inverter circuit which will give you 220V AC 50Hz with maximum power output of 100W. This inverter built using transistors for both the square wave generator module and the amplifier module. Inverter Diagram: The Q1 and Q2 used generate square wave. Q5-Q8 amplify the signal and the transformer to increase… Read More »
This is the circuit diagram of solid state relay. In reality, it is not a relay after all. There’s no ‘relay’ found, just the electronics circuit which does the switching. It operates a similar way as a relay; it is possible to use a low voltage to switch a higher voltage or better than ordinary… Read More »
A well-known IC LM35 is chosen to be the temperature sensor in this circuit. Output voltage of LM35 will increase by 10mV per degree rise in temperature. Output of LM35 is joined to the non inverting input of the operational amplifier (op-amp) of CA3130. The inverting input of the same op-amp could be provided using the required reference voltage using variable resistor R2.
This easy circuit makes it possible to monitor the charging process to a higher level. Final adjustsments are simple and easy and the only device required is a digital voltmeter for the important accuracy and reliability. Connect an input voltage of 12.65 volt between the positive and negative poles and adjust the 10K trimmer potentiometer until Led 10 lights up.

This motion filter effect circuit will controls the initial frequency and controls how much the envelope follower responds to the input signal. An envelope follower/filter combination translates the typical dynamic properties of your axe into modulated timbral changes too, you could feel of it as an automatic wah-wah pedal. Independent Initial Frequency and Sensitivity knobs… Read More »
Simple and easy build of sensitive FM transmitter circuit. The circuit only requires 2 transistors to work. *L1 = 0.1 Uh, 6 to 8 turns of 22 ga. hookup wire close wound around a 1/4 inch diameter non-conductive core such as a pencil Circuit Notes: Typically the default for the capacitors model is ceramic, preferably… Read More »
