Re: First Oscilloscope
You didn't mention bandwidth figures, but assuming you are looking for a digital scope, in that price range, look at the Rigol DS1052E: http://tequipment.net/RigolDS1052E.html $399, 50Mhz or the

First Oscilloscope
I am planning on purchasing my first new oscilloscope since the Heathkit one I built back in the 70's. I'm looking for recommendations and suggestions. My price range is somewhere around $500. I was

Re: Laser Pointer Life
We use these in a spectrometer at the radio telescope I work at. They last about 30,000 hours, then the emission loses its spectral purity as the mirror erodes. -- David Forbes, Tucson AZ

On the subject of blue LEDs, what do people suggest? The range is enormous, e.g. http://www.ledsales.com.au/catalog/index.php?main_page=index&cPath=148_152_154_155 What sort of brightness / viewing

Hi Dieter, nice pictures, I admire your photographer skills ;-) I would love to see the IN-2 clock. If it is nice and tiny enough I would nearly be tempted ;-) Best regards, Jens

Use the circuit that David has shown. The resistor values can be varied a bit, but use them in all the places shown. They are all important. The 'one transistor' circuit, you described is an 'emitter

Re: Transistor as On/Off Switch for Muxing - Why use two?
Mike, The reason to use two transistors is that you need a level translator to isolate the PIC output at 0-5V from the anode of the nixie tube which sees up to 180V.
