    Post some pics thread...

    Visitor this morning on the front fence, Common Bronzewing pigeon. This shot was taken through the lounge window, some distortion evident on the original, a little bit here on the feathers near the right side wing, at the level of the lattice work.

    Quitting Coffee.... please don't hurt me...

    Coffee, last cup August 1990, in Perth WA. Alcohol, a bit, but would like to see it off the list. No Smoking. I drink loose leaf tea using stainless steel infusers, no tea bags for me, can't stand them, to me the tea made with tea in bags taste mostly of cardboard.
  5. I agree this is a way to check, but I would suggest that the use of a reference diode similar to the LM336, this will give you accuracy, with a simple setup the same as a zener, ie one resistor in series. I could supply one LM336 5.0V if you would like?
  6. Perhaps you might see if there is an adjustment inside? Once you know what is the correct voltage you could adjust to suit? This meter is a Jaycar QM-1552, might pay to ask at Jaycar about the odd readings? Check in store with another, if the same then pass and buy a Fluke or similar.
  7. As a check you could use a resistor (nominally 1Kohm, read value with MM) as a load then measure the current through the resistor. Then calculate the voltage from the current and resistor value. Get another multimeter to double check the voltage? It may also be that the current limiter is set low, you may be reducing the voltage of the supply if the current limit is set low, usually both current limit pots fully clockwise, does not look like it though, the C.C light is not lit.
  8. There is usually a Vin(MIN) quoted or something similar (Vin-Vout=3V) for all regulators fixed or variable and will be different for each regulator. This voltage is the minimum voltage needed maintain line regulation anything below Vin(MIN) etc and the rated output voltage will mean the regulator is not performing at its maximum. The maximum input voltage is also to be taken into account as there is usually a maximum value quoted or / and an input - output voltage maximum.
  9. I have checked out a couple of datasheets on Mouser and they specify, working voltage of 5.5V, surge voltage of 6V - 6.3V. No mention of sustained voltage on these datasheets, I would use the working voltage as the sustained voltage. At 5V then you would have 1 - 1.5V overhead so that in my opinion would be OK. These also list the ESR on the 1 - 1.5F as 30ohms @1kHz. https://www.mouser.com/datasheet/2/87/Bus_Elx_DS_4327_KR_Series-479311.pdf https://www.mouser.com/datasheet/2/87/bus-elx-ds-4422-kw-series-479630.pdf
  10. Use a filter with higher maximum voltage capability prior to the regulator (whatever the type) and use the super caps after that on the regulated output. If you do that then 5.5V for a 5V rail would probably be enough overhead.
  11. Not using super caps here, more normally use something like this for my power supply filtering, this supply used 220uF 70V X 66 for 14,520uF. No reason why you could not do something similar to this and with 25 X 1F @ 5.5V (Jaycar RU-6705 @$4.15 ea $103.75). A reasonably cheap, easy thing to try? Would not be too big as the capacitors are listed as being 20 X 7.5mm. Would need more for 9V and 12V in series / parallel to get the voltage rating needed. Did see in the past some large 1F for car audio, I thought that they were 12V , not listed in the Jaycar catalogue that I could find. It may be possible to use this as a "battery" dependent on current needs, charge it, then disconnect from charger, no possible power supply noise then.
  12. Determining a resistor with a multimeter does not afford the number of decimal points that may be needed, especially in very low resistance requirements. I have previously written in another thread that one can easily measure critical resistance values using the two multimeter method. Pass a constant current through the resistor in question, no1 multimeter measures the current through the resistor , no 2 multmeter measures the voltage across the resistor. An example, if there is 15.64mA passing through and there is 1.56V across the resistor then by ohms law I=E/R, the resistance R=E/I, would be 99.7442ohms if my maths is correct (HP32SII), a double check - http://www.ohmslawcalculator.com/ohms-law-calculator This web site calculates to five decimal points, the value it returned is 99.74425. No BS meter needed here? Finding a resistor with that sort of accuracy would be the most difficult task.
  13. Spent the last 20 minutes or so listening to all the files in one listening session, in order of frequency 44.1 - 705. I feel that as I progressed through the tracks from 44.1 through to 705 the sound got more distinct overall, there was certainly more definition in the opening 1.5 minutes, more weight in the bass throughout the tracks, along with better top end. Nothing with the sound seems to be "off" with any of the modified files, in as much things don't deviate from the listening experience (no oddball sounds) rather the opposite. I did not notice as much change in the last two 352 and 705 as there was between the 44.1 and the 88.2, nor too much between the 88.2 and the 352 versions. There was a warmth to the sound that got better as the sample rate increased from 44.1 through to 705. @Ittaku Well done and thanks for letting me listen to the tracks, very interesting and a very pleasant experience.

    Tinnitus and the Audio Addiction

    I also have tinnitus in my ears, left all the time, right intermittently. I have also noticed that I have gradually been losing hearing in my left ear, always thought I had "something" in my ear, doctor visits up until a month or so ago were not helpful. Last month after a course of antibiotics for the "something" in my ear with little effect, I had an MRI and I have what is a called a Schwannoma growing inside my ear behind the ear drum, see https://en.wikipedia.org/wiki/Schwannoma I have an appointment with a neurosurgeon soon, that will tell me more hopefully. If you have a feeling that there is something in your ear suggest that you get it checked by a doctor, it did needed an MRI in my case to find it though .
