DC To DC Converter circuit used to be an convert voltage DC to DC with different concepts. DC to DC converter circuit +12 V to + /-20V is working to change the battery voltage from 12V DC to 20V DC voltage symmetrical. DC to DC converter circuit is often.... -
Here is a simple circuit that can be used as a tachometer. The circuit is basically a frequency to current converter which converts the incoming signal into a proportional current to drive the meter. The deflection on the ammeter will be proportional to the.... -
A multivibrator is an electronic circuit used to implement a variety of simple two-state systems such as light emitting diodes, timers and flip-flops. The monostable multivibrator will create a condition: in which one of the states is stabl.... -
A simple low cost Infrared LED speedometer is described that can be fitted to a skateboard, longboard or even a bicycle to measure speed. Notes on building, setting-up and calibration are given. When used with a low cost data logger continuous measurements.... -
On the amplifier circuit using ic STK, the same as my previous posting. However, in the above circuit has 2 inputs and 2 outputs, or commonly called a stereo amplifier. This issue of power amplifier 2 x 18Watt and has impedance 8. To stress that it takes.... -
Why are four legs connected to the green LED and two to the amber LED in the 4017 traffic light circuit Shouldn`t it be able to do with only one leg per LED Each output is consecutively active for the same time. By wired-OR-ing outputs you can create longer.... -
Attention! This strobe light circuit is connected to 220V, so measurements and experiments are very dangerous even after unplugging it from the mains. P1 p.... -
The white LEDs have different voltage and current requirements so they will need different resistors. So I`ll begin with a parts list: It`s the same idea as before, only the white LEDs are shaped differently because they have their own heatsink that they are.... -
The circuit described here is of an economical smooth variable power supply which offers 0V to 24V. It provides all controls and short circuit.... -
This is a chapter that was cut from Applied Robotics 2 because of space issues. It discusses motor control issues in general and then moves on to build a 5-amp motor driver. The principles involved can be applied to much larger motor controllers. Though it.... -
The device we then build will function as a metal detector that can scout out metal objects, such as coins, nails, keys such as car keys you may not be able to find, and even gold if you`re looking for in a beach (though this one may not have industrial.... -
This is the simple basic design of servo motor controller with pulse generator. It uses the CMOS IC 7555 in the Astable mode to generate pulses to drive th.... -
This digital-to-analog converter (DAC) integrated circuit is designed for lowest noise performance, both radiated and conducted noise. A recommendedconnection diagram for the ADV7123 is shown in the following schematic diagram. According tothe ADV7123.... -

If the green LED is on, the slave MCU is enabled. The MAX690 keeps the memory contents during power off. No resouces of the slave MCU are used. Wenn a SAB-C515 is used, it is possible to develop programs for the AT89-family easily by changing simply the port.... -
Switching power supply whose output voltage is appreciably lower than its input voltage has an interesting property: the current drawn by it is smaller than its output current. However, the input power (UI) is, of course, greater than the output power. There.... -

This is the circuit diagram of the simplest single chip AM radio. The circuit is designed around the IC ZN414Z which is a ten transistor tuned radio frequency receiver. The IC has only three leads and is available in the TO92 package. All necessary circuits.... -
These two resistors have two functions. One, if I touch the circuit by accident, they limit the current to a lower value. Two, when the flash fires, the main capacitor looks like a short circuit to the power supply. These two resistors limit the short.... -
Here is a circuit diagram of car stereo. Below is a circuit diagram of class B 15 Watts audio amplifier is designed using a dual op-amp and transistor. The 15 W class B audio amplifier circuit shown here is a simple class B audio amplifier based onLM833 op. .. -
The allowable reduction in system performance. For a fire control radar, the acceptable degradation is usually expressed as a reduction in range; for example, the maximum lock-on range might be degraded by 25 percent without loss of essential defense.... -
With the recent events at the Fukushima Dai-ichi nuclear power plant, I thought it would be pretty cool to build a Geiger Counter and hook it up to my NerdKit for interfacing with my computer. I`ve found this article which explains the building process.... -
The idea for this circuit came when the author had problems with the wireless speedometer on his bicycle. Such a device consists of two parts: the cycle computer itself and a transmitter that is mounted on the front fork. A small magnet is attached to the.... -
This circuit demands a control current that is 100 times smaller than that needed by a typical optically isolated solid state relays. It is ideal for battery-powered systems. Using a combination of a high current TRIAC and a very sensitive low current SCR,.... -
The motor controller is a custom built box that is a combination of custom printed circuit boards, the Pico Systems Universal Stepper Controller card, gecko G320 motor drives and internal power supply. The motor controller also links to the servos which.... -
Implementation of CAN for use in aircraft. The protocol is called CAN-FIX and is a part of the MakerPlane Open Source Airplane project. You can get more information on CAN-FIX here. The idea for this project is to build an Arduino shield that will let it.... -
JFET-bipolar cascode circuit will provide full video output to drive the CRT cathode. The advantage is about 90. Cascode configuration eliminates problems with JFET 2N4091 Miller capacitance, thus allowing the drive directly from the video detector. JFET,.... -
An external EEPROM can be useful for several different reasons. External EEPROMs allow much more data to be stored than is available on the 18F4520. In addition, EEPROM memory saves state when power is removed. In this project, we interfaced to a Microchip....
