you're a star, cheers mate

Ahh not to worry people. i've sorted it now. Just one quick question though, Anyone know where simple push to make switches are? (spring back ones) Cheers

A darlington pair perhaps ?

Hello everyone, I'm having difficulty trying to design a sequenced penalty counter which uses LED's per penalty and keeps the proceeding LED on. I'm not sure whether its me, or MultiSim which i'm using to create it that is the problem. Please remember i'm a student

http://www.figarosensor.com/products/822pdf.pdf Has your name written on it.

A very simple question to many of you out there i imagine. Could someone give me the resistor and capacitor values for an astable 555 with a frequency of 1 hertz? Thanks a lot Steve

Hello everyone, I'm in great need of a counter that will count up and down, and will count up to 30.. Does anyone know how to put two +- counters together to make a counter that will count up to 30, and down ? Thank you for any help Steve

How can i make a simple circuit, to create a clock, which counts down from 3 minutes, 2 minutes or 1 minutes. ( requiring adjustable settings ) The clock is to be fed into three seven segment displays. Can anyone help ? I'm thinking of something along the lines of a simple D type formation. Thanks in advance

What confuses me about this system, is that ii cant see that it would stay on once it has been tripped... Surely it would be best fed into a locking transistor ? with a reset... just a thought.

I'm designing a scoreboard for a mates karate competitions, and i need some really quite big seven segment displays. Can anyone tell me where i can get these and how much they'll cost.. I looked on RS components, but there doesn't seem anything really big enough on there.. i need them to be.. about 100mm diagonal.. How much are these going to cost me? thanks a lot Steve

How much voltage could you get from this system ? and how long did it take to charge the battery? Cheers Steve

Hello everyone, I'm interested in doing a project which uses renewable energy. Basically i want to use Wind power to Charge up a battery, which then, i can use for my computer during the evenings for instance. Has anybody here tried generating energy from wind? is it possible? Where could i get a decent generator and blade from ? Any general information will be greatly appreciated. Cheers Steve

ahh i see, ;D simpler than i imagined ;D

jesus, stun guns !? Is this stuff legal ? lol :-\

Just out of interest, do you have a circuit diagram, so i can see the full picture. of the bass extension circuit that is. Send to my email [email protected] if you want. Cheers
