    [HELP] Astable Circuit as Relay Driver

    Hi, if you look on the bottom of the relay, the pins should be numbered. 30 = 12v constant 85 = Gnd (negative) 86 = 12v load switch (your Transistor) 87 = 12v output to another circuit of your choice. EDIT: What transistor are you using? looks like emitter to Gnd (neg). If it's EBC, then the...

    Generator protection

    To be fair, here in the UK, people are quite happy on the grid. Solar wouldn't warm your socks. OK, just to reiterate my point. If the house is isolated from the grid it is safe to connect external power. The individual circuit breakers in the consumer unit will only isolate the individual...

    Generator protection

    You are right Gryd3. I was just following the terminology. I assumed people are talking about main switches and isolating the house from the outside. Martin

    Generator protection

    The answer is no then if you are living with other people in the house. If you 'know' the system and wiring ,and nobody in the house then yes. The whole point here is IF something happens! Your sister has no lights, so she goes down stairs to check the breaker. She see's it's off and turns it...

    Generator protection

    Just to answer the above response. It is very dangerous and possibly criminal. However, the question was is it safe. if your circuit breakers are OFF, it will work and is safe to do so. Electricians do it all the time with test equipment. The danger comes in when that CB is accidently switched...

    hooking up a counter and encoder

    Hi raesunrise95, Your picture isn't very clear. But the wiring colour code you supplied clearly shows the BLUE is ground. ie- negative or ground. This would be to a battery negative or to a chassis ground. I can't see it working from your picture. But the blue is ground.. Martin

    Compatible solder tips?

    Hi 8bit. There is the same as yours on Ebay right now. Only £4 and no bids. A little TLC and you could use the 'Ebay' iron as your main one and yours as a backup element. If you choose to buy a new one, I would recommend Antex irons. I have had 2 of mine for 25 years and still going strong...

    Compatible solder tips?

    Hi 8bit, The tip you need and the tip that fits are very different things. You are probably better to look on Ebay or take the iron into your local Maplin's and try what tips fit. Then choose the tip end you prefer/need. Martin

    lm386 and electret microphone problem

    Hi Stratos, I think your amp is really a pre-amp. Which is why it works fine with your computer soundcard. If you want to hear your voice through a speaker, you need a power amp too. Those terms are used loosely as in a pre-amp to another amp to amplify the output signal, which is your mic. Martin

    Hi Mike, Are you sure this is a 240v unit? I t should have the input voltages on a small plate or sticker. EDIT: How did you fit an earth to it from a 2 pin Euro plug? It would have only had 2 wires. Martin

    Learning C language

    To be honest no.. The reason I say that is because everybody has a different learning curve and can understand things differently. What works for me may not work for you. I would suggest you spend two hours looking at different videos and see which ones you like the format of. Some are very very...

    Bass Amplifier troubleshooting

    Hi Joe, sorry, I thought you sorted it!! I misread the post. Well, I don't really know what to suggest. When off, does it 'pop' when YOU touch it or poke it with a non-conducting stick? If it's when you touch, it sounds more like static. But when it's OFF I don't understand either. I don't think...

    Learning C language

    Hi Baxter, I have 'The Complete Idiots Guide To C++'. It is very good, but books don't speak to me or answer questions if I get stuck. I prefer watching hands on Youtube videos and guides. I find it's easier (for me) to see something rather than read. As already stated, the online guides and...
