JFET-input opamp circuit tl084 with commutator segment based on frequency selection you want you want done with potency
Signal and tone generators circuit for Testing and adjustments of audio and Measuring instruments particularly important aids and belong to the basic equipment of a Hobby laboratories. With respect to the waveform are often high demands on provided a sine generator, with the simple function generators not must be met. The here presented, with little effort your circuit works as “True” sine wave generator and provides very low distortion. The THD of at 400 Hz and kHz.
In addition to sinusoidal voltages can square signals with adjustable Pulse / pause ratio between Return 0 Hz and 00 kHz. The frequency of the generator is in switchable four decades and within the Decades infinitely adjustable with a potentiometer. Furthermore, the output level of the SG 000 is variable up to max. 6 Vpp adjustable. For power supply can be optionally an unstabilized 2V power supply or a 9V battery used. To use a 9V battery is at the generator off a Loading facility from the power supply available. In addition to the home lab is in a small plastic case housed Generator also

Designed for use in hobby projects delivers the signal generator SG 1000 very clean sine waves with a THD of <0.02% and square waveforms with adjustable Pulse / pause ratio. The frequency of the SG 1000 is between 10 Hz and 100 kHz. Signal and tone generators for Testing and adjustments of audio and Measuring instruments especially important tools and belong to the basic equipment of a Hobby laboratories. With respect to the waveform are often high demands on put a sine wave generator, with the not easy to function generators be fulfilled.

Solar Tracking Project TLC27L2 MC34164 Motor Control Circuit
Solar automatically detect circuit and turns towards him. Solar energy to the best use to solar tracking system circuit TLC27L2 opamp, MC34164 integrates based on the engine as a bridge 2N3906 and 2N3904 transistors and plowed the sun to the point where the correct motor movements that made a circuit for simple applications can be used. Also 2 pieces of solar cells as a power source circuit that is used but no need for an additional power source to the overall structure of the system according to engine size and not too strong a circuit ideal for simple applications.
