You see, that just didn't work for me as it is - 15/03/2008 in those countries that use 'U's all over the place.

So I have to wait for 13/1/4100 only a mere 2000 years to go!

The first part of your statement is correct, though R2 should be 200 ohms. The second part depends how the other modules are connected. Your sum is correct if you are connecting the modules in parallel with each other. In other words just extend your schematic to the right by adding on copies of wha...

Just in case you're wondering Jeep, the 3600 that Bigglez mentions is 3600 seconds which of course equals 1 hour. A 100 ohm resistor will give you your 20mA, but I'd suggest staying with the 120 ohm and see if the LED's are bright enough for your purpose. If your resistor has been manufactured with ...

Found it, jollyrgr. The schematics on the guts of a tuner VEQS0390 plus IF and video peripherials. I believe I also have that tuner, but will take longer to find. Can put it on the mail, it's a dozen pages. Contact me at externet at inorbit dot com, or -----------evenings. Miguel Miguel, you might ...

I suppose a downloadable pdf format e-zine would be relatively cheap to produce, the main expenditure would be contributors time - and the cost of the website.

Unfortunately I think there are only one or two others and they are produced in foreign countries. They can be purchased in an English format but are very expensive, somewhere around $150+ per year. One such publication is Everyday practical electronics but I have to say I ordered it for myself and...

I doubt tap water would be heated by an RF field.

Isn't a microwave oven a form of RF field ? - 2G4Hz does eventually boil water - though I agree not quite the same as an induction heater.

Pino, I think you meant to say 'use your imagination'. However, there is obviously interest in your compiler, so it would be better to make clear on your website, that the samples that come with the install are not able to be compiled with the trial/free version. I suggest including at least 1 16F84...

Well, what waffle I type. All my digital multimeters indeed do have a fuse for the 10A range, but my elderly analogue meter doesn't!

Most multimeters even the cheapo ones, normally have a glass replaceable fuse for the 10A range.

Just out of interest, I beleive what I call an RCD (Residual Current Detector) is what you call a GFCI. That being so, the normal retail and wholseale ones for that matter trip at 15 - 20mA unbalance. The rarer and more useful and expensive type trip at 10mA unbalance. I find it strange that in the ...

I'm sorry Dyarker, I have to disagree slightly. Brown is Live/Phase/Active call it what you will. Blue is Neutral/Return. If the device doesn't use a transformer, then connecting these the wrong way around may negate the safety earth - om other words if it uses a live chassis (quite possible) if the...
