Dark active Switch Circuit 741 Opamp

| 2012/06/09

with the LDR circuit diagram keep on working as a dimmer switch. Circuit, four resistors, a opamp, two potentiometers, an LDR, a switching transistor and consists of a lamp. Circuit, the value of resistor R1 ARD is directly proportional to the internal resistance of the 6-12V works as a voltage divider. Ldr1 depending on the…

Super Flyback Driver Circuit UC3844

| 2012/05/26

Author “Super final version flyback driver,” he said, but not so super stable than other simple flyback driver to control at least 555 UC3844 SMPS control IC is used instead. Flyback MOSFET driver circuit used irfp260, 12:18 ohm resistor connected to the source through the legs made ​​of current limiting. Attention flyback driver circuit produces…

Battery Charge Circuit 10Ah 200Ah Power Mosfet

| 2012/05/26

battery charging circuit faster than makes charging and BUZ11 mosfet power through a high circuit .. Charging circuit CD4013 based on the PR1 10K Potent with the output voltage can be adjusted if the battery kept charged continuously if the 13.8V charge and directly used and still be charged if the 14.4v charge voltage recommend…

400W Amplifier Circuits 2SC5200

| 2012/05/26

I think it’s one of the cleanest I’ve ever shared 400w amplifier circuits. potentiometers for setting the current calm, etc., with no need to make critical areas should be on the same printed circuit board feeding times specified values in voltj power transistors, except with less material. Amplifier output power transistors used 8 2SC5200 working…

8 Channel 24 Amp Triac Animation Circuit PIC16F628

| 2012/05/22

Hello Friends For a long time I did not do my share. I looked at my little library amusement park six months ago I prepared for bi TRIAC 8 Channel 24 saw the animated card. Obviously things I’d forgotten due. After getting a bit of project files I thought I’d share with you. Card design…

Phone Rings Lamp Circuit MOC3020

| 2012/05/22

The circuit in the picture when connected to a telephone line with any incoming calls will allow the lamplight. Circuit is in two parts and the two circuits are separated from one another by MOC3020 optocoupler. MOC3020 Optocoupler, without an electrical connection between the low voltage with high voltages and currents can control is called…
