How to make Step By Step Making Crossover Cable,
What you need to make Crossover Cable
Cable - Be sure the cable(s) you are using is properly rated for CAT 5. It should state clearly on the jacket of the cable, what it is rated at. One option that you have when selecting your cable is to use a pre-made normal 'straight through' cable, and simply whack off one of the ends, and replace with a new "Crossed Over" end. For the purpose of this article, though, we aren't going to go that route. We are going to make the whole thing from scratch - using bulk CAT 5 cable.

Running Message Display circuit diagram

Running Message Display circuit diagram

Light emitting diodes are advan- tageous due to their smaller size, low present consumption and catchy colours they emit. Here is really a running message display circuit wherein the letters formed by LED arrangement light up progressively. As soon as all the letters of the message have been lit up, the circuit gets reset. The circuit is built around Johnson decade counter CD4017BC (IC2). Among the IC CD4017BE’s features is its provision of ten fully decoded outputs, creating the IC ideal for use in a whole range of sequencing operations. In the circuit only one of the outputs remains high as well as the other outputs switch to high state successively on the arrival of each and every clock pulse. The timer NE555 (IC1) is wired as a 1Hz astable multivibrator which clocks the IC2 for sequencing operations. On reset, output pin three goes high and drives transistor T7 to ‘on’ state. The output of transistor T7 is connected to letter ‘W’ of the LED word array (all LEDs of letter array are connected in parallel) and therefore letter ‘W’ is illuminated. On arrival of initial clock pulse, pin three goes low and pin 2 goes high. Transistor T6 conducts and letter ‘E’ lights up. The preceding letter ‘W’ also remains lighted because of forward biasing of transistor T7 via diode D21. In a similar fashion, on the arrival of every successive pulse, the other letters of the display are also illuminated and lastly the total word becomes visible. On the following clock pulse, pin 6 goes to logic 1 and resets the circuit, along with the sequence repeats itself. The frequency of sequencing operations is controlled with the assist of potmeter VR1.

Automated Dual output Display

Automated Dual output Display .This circuit lights up ten bulbs sequentially, 1st in one direc- tion and then within the opposite direction, thus presenting a nice visual impact. In this circuit, gates N1 and N2 form an oscillator. The output of this oscillator is employed as a clock for BCD up/down counter CD4510 (IC2). Depending on the logic state at its pin 10, the counter counts up or down. In the course of count up operation, pin 7 of IC2 outputs an active low pulse on reaching the ninth count. Similarly, during count-down operation, you again get a low-going pulse at pin 7. This terminal count output from pin 7, soon after inversion by gate N3, is connected to clock pin 14 of decade counter IC3 (CD4017) Automated Dual output Display . which is configured here as a toggle flip-flop by returning its Q2 output at pin 4 to reset pin 15. Thus output at pin 3 of IC3 goes to logic 1 and logic 0 state alternately at each and every terminal count of IC2. Initially, pin three (Q0) of IC3 is high as well as the counter is in count-up state. On reaching ninth count, pin three of IC3 goes low and as a result IC2 starts counting down. When the counter reaches 0 count, Q2 output of IC3 momentarily goes high to reset it, thus taking pin three to logic 1 state, as well as the cycle repeats. The BCD output of IC2 is connected to 1-of-10 decoder CD4028 (IC4). In the course of count-up operation of IC2, the outputs of IC4 go logic high sequentially from Q0 to Q9 and therefore trigger the triacs and lighting bulbs 1 through 10, 1 soon after the other. Thereafter, during count-down operation of IC2, the bulbs light within the reverse order, presenting a wonderful visual effect

Pengertian Pulse Width Modulation (PWM)

Tuesday, March 1, 2011

Pulse Width Modulation (PWM) is a method of controlling the power used in most electronic devices, for example on the PC Power Supply, UPS or power supply2 on other electronic devices. not only used to control power, the PWM can also be used to regulate electronic devices such as servo motors.
As the name Pulse Width Modulation or Indonesian language Pulse width modulation is a form of voltage signal is changed change the pulse width to be drawn more details can be seen below.

Pulse Width Modulation (PWM)

In the picture above shows there are five kinds of fruit with 5 PWM Duty Cycle value 0%, 25%, 50%, 75% and 100%. Duty Cycle is a parameter that indicates the ratio of the PWM signal is logic 1 (5 volts) and the signal logic 0 (0 volts), for example:

PWM Duty Cycle 25% with a period of say 100ms will mean a logic 1 on the PWM signal is 25% of the total signal period or 25% of 100ms = 25ms, while for the signal to the PWM logic 0 is the remainder or 75 ms.

The use of PWM in power control is more efficient when compared with the conventional method of controlling power (resistive circuit), since no power is wasted into heat.

PWM can be generated in several ways one of them is with a Microcontroller and use Timer IC 555.

Skema Adaptor Dengan Trafo Ct

Skema Adaptor Dengan Trafo Ct,To test the Stax "earspeakers" I want to set up a transformer based adapter.

(A basic "work notworks" test, while waiting to build or buy a dedicated amp.)




Did I understand correctly, that this adapter is made of center-tapped step-up tranformers, where the center tap is biased, as the diaphragm, to an appropriate voltage (580V for Pro, 230V for the Normal)?Skema Adaptor Dengan Trafo Ct,


If this is the case, here is my second question(s):

Can this be done with "normal" center-tapped output transformers?
I have two smallish transformers from an old ECL82 amplifier, that have say "3.5" on one side and 5000 Ohm" on the other sidez (this oen being center-tapped).
Can I expect these to withstand the bias voltage?


Could this be done with "100V line transformers" from a 100W PA amplifier?
I have two of these, and it seems like the taps are symmetric (I'll test more accurately) and function as step-ups.
These look "bulky" to me (2Kg weight and thick conductors) but again, would they stand 580V?



Thanks for any help.
I would normally "just try it and see what happens".
But in this case, even if I can keep the bias voltage low, it needs to be high enough to discourage such an approach; not ready to sacrifice those trafos, let alone the Stax-es...
