This circuit is describes about sensing air flow using microcontroller PIC16C781. In this circuit is using Programmable Switch Mode Controllers (PSMC) that combination between the Integrated Operational Amplifier, Digital-to-Analog Converter (DAC), and gated timer to construct a thermally operated air flow sensor with minimum external components. This is the figure of the circuit. Air flow [...]
The work of the power supply is the gain of 2N3053 2N3906 and 2N3904 is fixed internally at 2Watts. 2W switch power supply circuit It is to compensate the reduction of output power due to low voltage supply the transistor uses the Bridge-Tied-Load principle (BTL) which can provide an output of around 1.5 to 2 [...]
The amplifier circuit output is 3 watts in tube Class A with the 6BX7 tubes used to draw. The project has a normal gain entry to the regular “Fender-like set of” full-range control, treble, bass, midrange and volume. It is also possible for extra high gain jack, the second phase of the tunnel and its own gain control. [...]
The EL84 is one of the best pipes ever made, IMO, 3-triode EL84 wired in parallel and replace a sonically outperform WE300B in the same circuit (circuit originally 300B). 5W Tube Power Amplifier with EL84 And each of you probably know, I’m not a fan of tubes parallel to all.I would be very interested to [...]
It is a classic design of the last 35 Watt amplifier, and 2 push-pull EL34, Siemens and Halske. The amplifier has been from 1954 to 1989, when it came out, except that the operation, the average activity for 15 hours a day. It is not present in damages in excess, in particular the replacement of [...]
50 Watt apmplifier with TDA1514A Here is circuit audio amplifiers for car, which use it only number Transistor Circuit of IC, simple Circuit (and Top Popula) Use TDA1514A transistor at low cost. It best Idea Circuit. It’s receive a handful of additional external device in comparison to the generic diagram. Remember that there’s a simple HF filter on input signal. [...]
LM317 Variable Power Supply Regulator A circuit is timeless. LM317 regulator is a versatile and highly efficient 1.2-37V voltage can provide up to 1.5 Amps. of current with a large heat sink. It is ideal for almost any application. This was my first power source workbench and I still use it. Since LM317 is protected [...]
