I'll also nominate the Rigol DS1052E FTW. Love mine. Around 400 bucks American. You can find it on Amazon.com. -- carl -------------------------------------------------------- Henry Carl Ott N2RVQ

Re: Laser Pointer Life
I built one using inexpensive lasers http://users.rcn.com/ted.johnson/scanning_laser.htm To make the laser react fast enough to display something interesting, I had to remove a lot of the over-voltage

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

Laser Pointer Life
I am looking to construct a clock involving the use of a laser. I am thinking of an over the counter laser pointer. Can anyone tell me the average life and duty cycle of your run of the mill laser

Run of the mill = Laser LED (not HeNe) cheap keychain one. Ok, I setup one to point at my viewhole on my front door. Runs 24 hours a day. That was about 5 years ago. No, I have no good reason for

blue LEDs
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

Re: Some updates
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

Re: Transistor as On/Off Switch for Muxing - Why use two?
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

You know. I have to agree. Mine is just terrible too. I think it keeps better time than my Citizen ATom watch. My Citizen gets more attention, because I have had to mail it in twice for repair. My DF

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.
