it's my luck or what 
i'm unable to make anyof the noise gen. circuit work...though the idea seems simple but just couldn't get them to work....VCO is just waiting for the tune voltage...
any idea what to trouble shoot?
thanks
what vco in use...?
Chris
my circuit work from first day on... ?
It's just a tiny circuit with comperator and integratior set together in a loop
Max2623 and POS1060 both of them. Well I have access to scope in uni only in home i work on computerized scope through sound card, but the problem i don't know what would be. when things go wrong, start wiring it again. I'll see. I was able to produce sawtooth through MC1458 but then the DC offset wasn't mixing well. The amplitude of sawtooth suddenly became small, very small when mixed with offset. I'll work on it too, see if i find anything troubling.
Now differnt people have different kinds of hobbies, for example some people like swimming, some people like running and some people like hiking. However now a lot of people have developed a new kind of hobby, it is metal detecting and there are also device that have been invented to help people with their hobby such as the gold metal detectors and the metal detector and so on and you also can make a good choice as there are many types that are provided for you to choose.
There are many types of detectors in the market, so it is really hard to make a decision which one to buy and whee to buy. I searched the internet for a long time and then I bought a gold metal detector, which is really helpful. And when I do metal detecting outside it can really distinguish what kind of the metal that it has detected and give an indication for me. And by using such kind of device I have saved a lot of time and energy. In a word, I love the gold metal detector and have confidence in it.
