apple macintosh midi interface schematic basic version

The digital voltmeter (DVM) provides a direct reading of the sensor's temperature in degrees Celsius. The temperature sensor IC1 generates a nominal 1 µV per degree Kelvin, which is converted to 10 mV per degree Kelvin by resistors R1...

The amplifier circuit utilizing the STK4050 integrated circuit (IC) is known for its robustness and high quality. This article presents a 200-watt power amplifier circuit based on the STK4050. The circuit features an advanced auto wiring diagram with color-coded...

In the circuit below, 60 individual LEDs are used to indicate the minutes of a clock and 12 LEDs indicate hours. The power supply and time base circuitry is the same as described in the 28 LED clock circuit...

This circuit is designed for pulse width (time) to voltage conversion. According to the component parameters in the diagram, it can convert a pulse width of 0.1 seconds into an output voltage of 10V. When a conversion pulse is...

The circuit depicted is designed to protect a system from power supplies that may exceed safe limits. An example of this is small consumer products that utilize external AC adapters, where there is a risk of accidentally connecting the...

Here is a simple project that sends continuous or switch controller MIDI messages that correspond to the position of a potentiometer. Given a few parts and a cannibalized volume or wah-wah pedal, you can build this MIDI controller pedal...
