UGN3503 Hall Effect Sensor High Current Measurement

| 2008/11/30

Now let’s briefly circuit and try to explain the working principle. When we examine the data page UGN3503 Hall effect element elements are the analog watch that works. So the magnetic flux is genliğin to transfer to a suitable voltage. Do not try to apply these principles in clampmeter? There used UGN3503 assumes the role…

Parallel Port DC Motor Speed ​​Control with Turbo C

| 2008/11/23

Turbo C Of dc motors speed control done in two ways first excitation current by modifying it happens for the moment does not concern us Another method applied voltage by changing the motor speed can change thus this method is the usage of applied voltage DC (Direct Current) chopper (Converter) circuit is replaced by. Parallel…

Photo Flash 220V Flasher Circuit

| 2008/10/31

Old scrap the camera of your Flash components to help you evaluate a simple circuit actually machine other parts of the acts now flasher circuit and the administration let the circuit I used triac T1213MH flash to burn high strength low güçd the triac used my hand also is not used flasher circuit used in…

Lighting Circuit with White LEDs for Camera

| 2008/10/27

Prepared for a professional camera, I guess it fits many models. Also, there are examples of pictures taken with led lighting. The circuit works with 12 volts, the control IC HEF4538BP. Taking very close shots requires the right additional lighting to eliminate the shadow of the lens and gain depth of field by allowing the…

10KHz – 1.2GHz Frequency Meter with LCD Display

| 2008/10/23

The design of the meter is the result of many experiences in the use and construction of various frequency meters, both factory and amateur. From these experiences, there are several characteristics that a good meter should fulfill. These: – fastest possible refresh rate (limited only by timebase and prescaler part), – prescaler input cyclically reset…

80M Transceiver SSB-CW LA1185

| 2008/09/25

I’ve made a few changes to the design of the transceiver. Changed the layout of the printed on the plate. Dodalem emisje CW. I added the emissions CW. Pressing PTT microphone transmitter runs in the SSB mode, pressing the key forces CW emissions at the same time blocking the track microphone. If you plan to…

220V Led Flasher Circuit Simple , Transformerless

| 2008/09/09

There is a very simple flasher circuit transistor integrated 470k, 680ohm, 1n4007, 22UF, cardiac and led 470k resistor is not in my hand I used 560K Diac Wiki The DIAC, or “diode for alternating current”, is a diode that conducts current only after its breakover voltage, VBO, has been reached momentarily. When this occurs, the…

12V 50W Peltier Refrigerator

| 2008/09/05

The mini fridge project is made in the simplest way using very few materials. In addition to 1 12v 50 watt peltier thermal switch, CPU cooler, 12v fan and 2-position switch, 10 amp fuses are used for safety. In fact, since the refrigerator will be used for cooling, there is no need for a two-position…
