1000W MOSFET stage Master MK2
1000W MOSFET Description:
Fifth Generation HEXFETs from International Rectifier utilize advanced processing techniques to achieve extremely low on-resistance per silicon area. This benefit, combined with the fast switching speed and ruggedized device design that HEXFET Power MOSFETs are well known for, provides the designer with anextremely efficient and reliable device for use in a wide variety of applications.
The TO-247 package is preferred for comme rcial-industrial applications where higher power levels preclude the use of TO-220 devices. The TO-247 is similar but superior to the earlier TO-218 package because of its isolated mounting hole. The 1000Watt MOSFET LEGEND stage Master MK2 is a very good and powerful amplifier. It is not into the classroom HiEnd sure, but very respectable sounding unit with lots of of power. It was not designed with home interior as the primary goal before, such a power used only rarely in the house and indoor except perhaps in some larger nightclubs. Frankly, due to a high performance, could PA light rather go class, but other specifications and great quality over the PA standards and needs! My only additional suggestion for you to think about it at length, Master internship as a Master MK2.Internship Master 500 ... 1000W, but is aa little easier (and cheaper) to build. "PCB show thus as below 1000W mosfet PCB 1000W mosfet PCB.

Simple Sixteen Stage Bi Directional LED Sequencer
The bi-directional sequencer uses a 4 bit binary up/down counter (CD4516) and two "1 of 8 line decoders"74HC138 or 74HCT138) to generate the popular "Night Rider" display. A Schmitt Trigger oscillator provides the clock signal for the counter and the rate can be adjusted with the 500K pot. Two additional Schmitt Trigger inverters are used as a SET/RESET latch to control the counting direction (up or down).
Be sure to use the 74HC14 and not the 74HCT14, the 74HCT14 may not work due to the low TTL input trigger level. When the highest count is reached (1111) the low output at pin 7 sets the latch so that the UP/DOWN input to the counter goes low and causes the counter to begin decrementing. When the lowest count is reached (0000) the latch is reset (high) so that the counter will begin incrementing on the next rising clock edge.

The three lowest counter bits (Q0, Q1, Q2) are connected to both decoders in parallel and the highest bit Q3 is used to select the appropriate decoder. The schema can be used to drive 12 volt/25 watt lamps with the addition of two transistors per lamp as shown below in the section below titled "Interfacing 5 volt CMOS to 12 volt loads".
