    in search of a FM STEREO transmitter

    Hi rasOfir, and welcome. You really need to know what you're doing to take on such a project. I have made an FM stereo transmitter using the (BA1404) FM stereo transmitter IC, for the same reasons you want to, it does every think that you want, well almost. the transmitted sound quality is not...

    How to use a PID circuit to regulate temp.?

    Sorry zgnoh, it's unlikely I will be able to help you any further. Of course you can ask for help :), someone else knowledgeable in this area will surely help you 8).

    Making an electric furnace.

    Ante, I misunderstood what you meant, my DMM had a flat battery so I had to use my backup, FTM finger touch Meter ;D, unfortunately it doesn't work any more its not broken, It just refuses to do any more testing ;D ;D. Thanks again for the advice Ante, I'll get started on this project today and...

    Making an electric furnace.

    Ante, so it's a bad idea, I think this is what you are trying to say ;D ;D ;D ;D ;D. Well would you believe I forgot that I had salvage two of these(BTA40-400A) 40A 400V ::), it's casing is isolated and I can easily mount it off board, more than adequate to handle the current and I only need to...

    Making an electric furnace.

    Hi Alun, Funny you should mention that ;D, the TRIAC wasn't insulated from the heat sink with my first test run. I thought it over before I touched it to see how hot it was getting, and came to the conclusion that it should be LIVE :o. Being an adventurous kind of guy, I touched it quickly...

    Making an electric furnace.

    Thanks Ante :), I probably wouldn't of taken on a mains power project like this, if I didn't have somewhere someone to ask advice :). About the cooling fan(DC 12V 0.13A), is there a way I can use it without a transformer, reduce the voltage down enough to use a bridge Rectifier and voltage...

    Making an electric furnace.

    No worries Ante, I have pretty much got those capacitors sorted out now ;). I decided it would be a good idea to place this project inside a insulated box for testing and safety, considering my lack of experience and I was playing with 240V ;D, but it turned out so well I was hoping I could fit...

    Making an electric furnace.

    Ok I'm nearly done with the electronic side of things. I have almost got it right, the only real problem I have had so far is choosing the right size heat sink. I gave it a test run connected to an electric heater, with the heater set at 750W and the light dimmer set to maximum, I could hold...

    Subject Line Descriptions

    MP, I can see how it must annoy you and others, it doesn't bother me but you are right. I think (read this before you post) is a good idea.

    pressure sensor help...

    I just thought of something else to add, if you use two probes at the bottom of whatever it is you drop in the water. The water will act as a switch, a conductor linking the two probes electrically triggering the start of the event, and the Hall affects sensor indicating the end.

    pressure sensor help...

    Here is an idea, that may help. At the other end you could use a solenoid latch, that when triggered will drop something into the water, then you'll need to link both devices to some think that can record the event.

    Making an electric furnace.

    Yes, good thinking Ante I'll do that. I have a couple of questions, as usual ;D. In the components list for the capacitors, it says to use dipped polyester, are these Green caps ??? metallised polyester. In the pic they are blue, I have a heap of recycled Green caps some of which are brown, I...

    TDA7000 - FM Radio

    I also got one of those little radios for free, after purchasing a certain amount at a newsagents, my daughters schoolbooks. I didn't realise it at the time, but they were actually giving me a little plastic case, with a few useful components inside ;D, that little plastic case is going to...

    Making an electric furnace.

    Hi Ante, Ldanielrose, Thanks for your reply :), Ldanielrose, I have experience casting with oil based sand and die casting, large floodgates and irrigation valves, I'm going to give Green sand ago to start with. I'm going to use a steel crucible. I won't be using any flux unfortunately. I...
