    Frequency Generator

    At first I want to know it is possible to build. (cheap, I havent got a lot of money) I want to make frequency between 10 HZ and 30 Hz. (With Ne555 IC and a potmeter, because it is cheap) It necessary for the VCR head I want to change the frequentely with the potmeter? CAn somebody give me a...

    I have an experiment with coils (I manage to this) You have to give a frequency to the coils (but not 50 Hz, it depends on the revolution) RPM/60 = frequency But I dont know the RPM (How can I determine the revolution) and I dont know how can I produce the frequency (with a signalgenerator, I...

    EPROM

    I have an experiment with EProm (D27128) I wired eight LED to the Data Pins and I give +5V to the ROM. (nothink happenned), but when I give +5V to P (program) PIn , some led lighted. If I put +5V to the A pins (a0,a1,a2,a3,etc) the led lighted a lot of varieties. Can you speak any other...
