    Takes a real man to admit mistakes, cowards edit them out.
    Show me a man who never made a mistake and i'll show you a man who never did anything.
    Everyone has an opinion but it doesn't make it right.
    It's the mistakes that we learn the most from e.g. beware of these pit falls.
    Great vid and thanks for sharing, mistakes and all.

      ISO Guy I came here specifically to express these same sentiments. I respect and trust people who admit their mistakes WAY more than people who hide them. THAT shows that you have confidence in your abilities and yourself. On top of that, it shows that you aren’t afraid to fail, and being afraid to fail is often what keeps people from living up to their full potential. Bravo for having the guts to thumb your nose at failure! Thanks to your character, now we have ALL learned one more way not to do a thing. Keep up the good work.

    Glad to see I’m not the only one who can build it perfectly on a breadboard, but get distracted or something when I’m making the schematics, and I don’t catch it till after I’ve ordered the PCBs. Normally I have fried a chip or two in the process. I have honestly got in the habit of finishing up the board design, then I’ll wait a few days, go in and double check everything, do this again a few days later, and maybe I’ll do it a third time. I just need time to sleep on it I guess and to get away from it so I’m not going to convince myself I did it right because I’ve been looking at it a lot lately so I know it’s right... usually takes me a week once I’ve completed it, and I always find a few things. Great video as always, and I actually like this channel because it’s not scripted! Is nice to see people who can talk about this stuff off the cuff, has a more relaxed feel. so what if you said transformer instead of transistor, we know what you meant from context.

  • @nigeljohnson9820
    @nigeljohnson9820 4 года назад +2

    The circuit diagram shows the capacitor on the trigger connected between rail and ground, I cannot see how this can work.
    From a more general point of view, there is a joke about a car driver who stops and asks a local for directions. The reply he gets: " if you are going there, I wouldn't start from here". I question if the 555 is the best choice for this project, when there are many better solutions.The 555 needs two resistor adjustments to control the frequency and the mark space ration of its square wave output, as the timing capacitor charge and discharge times are set separately. A further problem of providing a frequency adjustable output is that a tunable low pass harmonic filter is required to turn the square wave output into a sign wave.
    There are single IC function generators on the market, admittedly the digital ones require a controller of some sort to program them such as the AD9833, but there still a few analogue ICs on the market. I refer you to the XR 2202 or ICL 8038 (which is a near perfect fit).
    The traditional approach is to make a tunable Wayne Bridge oscillator, as this provides a sine wave output, and it is always easier in the analogue domain to turn a sine wave into some other wave forms than do the reverse, without using a significant number of components. Triangle wave forms can be generated using a constant current output oscillator to charge a capacitor. The square wave can be generated either by limiting the sine wave signal or feeding it through a digital divider t type flip flop. For a simple circuit, i might choice my old favourite the quad Schmitt trigger as the square wave oscillator, or maybe a quad op-amp. The latter offers a number of way to generate the wave forms required.
    In the past, I have used 4017 Johnson counters to synthesise a pseudo sine wave output, using resistors into a summing op-amp.
    An R2R resistor ladder network makes a low cost D to A, that can be used with a memory to generate programmed arbitrary waveforms. A 7046 PLL can be used to generate square waves up to 18MHz.
    For a fixed frequency generator, my inclination would be to use a crystal oscillator and divide down to the required working frequency. The 555 was never my favourite circuit, because it always seem to be so limited and there always seems to be a better option.

    I don't think you can beat the $3 price point for a 555 function generator module from the Chinese ebay/aliexpress/whatever sellers but maybe you can make something which is more interesting for modders and tinkerers for a bit more. I think you do a little miniseries how all the circuits work and what is what people will benefit more for having this particular one so they can follow up on the thinking and improve the unit or whatever.

  • @nigeljohnson9820
    @nigeljohnson9820 4 года назад

    May I politely suggest that you down load the linear tech application notes on low distortion audio signal generator. This uses a Wayne Bridge circuit with AGC implemented with linear tech high speed op-amps. The component cost should be low as there are not many components used in the circuit. It will also be relatively easy to add an additional comparator or op-amp to generate the required square and triangular waves. Failing this can I suggest that you look at the ICL 8038 precision waveform generator IC. This cost approximately £2.39 and has very few external components to make it work. Both the above offer better solutions than the 555 circuit and would be worthy of development on a PCB.
    I commend the use of the myriad of application notes that the IC manufactures produce, particularly those of linear technology and Texas instruments. These are always a good place to start when considering a new project. It is up to the individual or they chose to simply copy the application note circuit or to refine and improve it to meet their needs. It is not an admission of some designer short coming to use such application notes and the technical notes that go with them. It is not our job to reinvent the wheel, but we can make improvements to it and taylor it to our needs.
