    PLease Vote: Electronics Engineer Vs Computer Engineer

    An electronics engineer could program (not ofcourse so advanced as a computer engineer) but a computer engineer couldnot design circuits..... So i vote electronics enginner.... Of course you must do what you love.....

    Ring Oscillator with Delay

    you could use a powe supply voltage supervisor ic like the tl7705 that will produce a programmable pulse when you connect the power. (it was design to give the reset signal) you will AND gate this signal with your clock Alternatively you can use o CD4541 ic that will drive the AND gate that...

    [SOLVED] CPLD clock source question

    connecting to clock source fpga Any experiment board should use a clock source. If your cpld has enaugh flip flops use an integrated crystal oscilator with a frequency between 4MHz and 50MHz, and you will use flip flops to divide it. In any way you will never use a 555 ic to give clock to...

    LM317 output Currrent

    lm317 20a Its better to use L200 with external transistors because in most circuits that use lm317 with external transistors there is no current protection for the external transistors. In L200 with external transistors there is current protection. You will find circuits with L200 in www.st.com...

    Which Microcontroller Do You Use?

    c8051f340 free c compiler Atmel AVR microcontrollers are very easy to use (simple programming model) have low cost and you can find them everywhere. Also all AVRs too fast. So I use the 8515 (at90s8515 -atmega8515), Atmega162, and the 2313. Also very nice microcontrollers with very flexible...
