    Driving 740 LEDs with variable intensity

    Hello, You need to control all leds together or you must be able o change each led? The first is easy. Actually you have several possibilities, from custom DC/DC controller to using of standard LED controller you can see this type of controllers from TI Company. You must know that the White...

    pls help me regrading microcontroller

    Hi, what exactly you need? About the project, this is a simple and easy to realize. Because you have RS232 I hope you need only two point connection, because multi point with RS232 is a bit difficult. First think is to get a decision what type be a protocol of communication, master/slave or not...

    Please help in the MOSFET driver

    Hi, This chip is MOSFET driver, not a motor driver. The mosfet haven’t the gate current, this 3A impulse is only from the capacitance between gate and Source. What type of motor you will drive?

    help me create a racing timer

    Hi, This is to same like a laser device. Laser device is better, because the light ray is more coherent, and will be an easier to obtained big distance. The problem their can be the noise, from son, from lamp, from headlight. To reduce this signal you must use a more intelligent sensor. If you...

    need Sim Software ?

    I not sure that you need a model for the processor, and I am not sure that Intel can provide some model. They has internal model, but they is not suitable for the PCB design. Actually you no need from this model. Only one that you need is a good PCB soft, in your case the best decision is a...

    help me create a racing timer

    HI, IR optical barier is very suitable. Way you think that F1 timer is expense, in this timer have not nothing special. You can do this very easy. What you ant to create, or how. You want to use standard device, like a sensor, timer etc and just connect them, or you want to make the timer and...

    Conveyor Belt

    Hi, you can made different construction. The traditional conveir belt is a one or two draving wheels, depend from this one or two direction is movement, and several secondary wheels between them. The belt can be set in motion with friction or with cogwheel. In your case i think you can use...

    PCB Etching Tank - Do it yourself

    Hi, presured air, from compresor, via reducer, in compresor tank the presure is around 6 bar, after reducer valve the presure is below 1 bar. But now i think taht temperature of air can be higir that room temperture becouse the compresion, and this may be is a reson for the voaporation.

    op amp response time

    Hi, nobody .....  to get the answer must have a question. Type of the OPAMP, and signal, for example LF411 : Inverting Small signal ~ 200 nS Non Inverting Small signal ~100 ns Inverting Larg signal ~ 1.8 uS Non Inverting Large Signal ~ 1.8 uS Curent Limit Mode ~ 10 uS

    Data Transferrinf Over a 25 Meter Wire.

    Hi, the RS485 is very good decision. Afcourse you can use CAN but if you have not a controller with a can module will be a needless work.

    Data Transferrinf Over a 25 Meter Wire.

    Hi, if this is only one way connection, you can use the RS232 with a current loop, or RS422. If you whant a real multi node network, then RS485. If you want something a bit hi-tech you can use a low speed optics, HP has a this type of trancivers, actually this is the agilent, a HP company.
