I need the source for this, I remember hearing it somewhere.--Arjs 12:11, 20 July 2007 (EDT)

line voltage

Never minding the fact that all round (non-USB) ports should tolerate line voltage, how might one make a safe connection? This is useful for showing line frequency and for showing the waveform. Waveforms from UPSes might be particularly interesting. Not being an EE, I can think of a few ideas: transformer, capacitor, resistor. Each of those can be done nicely, with proper electronic parts, or crudely with makeshift parts. 24.110.144.116 00:42, 1 August 2007 (EDT)

Measuring voltages outside 0.3V - 1.9V would require an external probe, the development of which is also in the pipeline.--Arjs 02:37, 15 August 2007 (EDT)

What about the reverse?

Measure turns the audio input into a generic input over a certain voltage range with essentially 0 current. Would it be possible to do the same for the audio output? This could run simple robotics, or allow switching between sensors. Obviously it would NOT be usable as a DC power source, just for switching transistors. Homunq 20:38, 7 August 2007 (EDT)

I have been thinking about that too. It would be interesting if I am able to achieve that. One of the other things that I have been thinking about is a simple generic USB based I/O interface. USB to Parallel chips aren't that expensive too...--Arjs 02:35, 15 August 2007 (EDT)

See Electrical output for further discussion of this and related possibilities...

Maximun frecuencies

hi Arjs where can i find the specs of measure..i.e maximum frequencies and stuff..?

The maximum sampling rate of the Ad188 sound chip is 48khz , which is the sampling rate I am using. I would say that maximum frequency would be about - 15Khz (slightly less than Fs/2). --Arjs 02:19, 15 August 2007 (EDT)
