    Good. Still a bit surprising as I have used the TIC206 with no problem

    well it is not much different from using an Arduino. there are several ways to communicate with the ESP8266, but you could have it serve a webpage with a box on it in which you can enter a dimming level. Probably could make that a slider too. That dimming level you then use to determine the phase cut of the TRIAC

    A PWM Dimmer Revisited

    "3 smaller caps in parallel will reduce the ESR (whatever value that ESR would be)."Presuming that the ESR does not vary much with the actual capacity of a single capacitor (meaning that say a 100uF has a comparable ESR to a 10uF), this would ideally divide your ESR by 3 (I know, simplification)

    I admit, at my age I may stick in a wire at one end, and already forget where it is supposed to go when I get to the other end

    Just a remark about the breadboard issue. I fully agree. I had used the breadboard only as a quick test, but even with low voltage i never use breadboard for a final setup. Mainly because wires can become loose and then after a few months one may think Hmmmm, where did that yellow wire plug in again :-)

    A PWM Dimmer Revisited

    If my eyes dont cheat me you have a 66kOhm (5x330) in the voltage divider, so with 30uF, and say 300 Volt you'd be around a 15 Volt charge in 100mS. But as you do not short out the full charge, I think you will not really have a problem there

    thats true, i kinda used it loosely in analogy to the original design

    A PWM Dimmer Revisited

    Looks great. Very tidy.Regarding the high voltage capacitor in my earlier design, that was to avoid any heating issues caused by RC delay on the gate voltage.However, by now I can confirm that a 50uF low voltage cap on the low side of the voltage divider works just as well, without noticeabe heating of the FET. The 22uF in your design probably does too, but I just did not try that yet :-)

    Thejo, in the comments this issue is addressed several times, Triacs are just not the most suitable to regulate motors. They can but humming, usually caused by harmonic distortion of the wave pattern is often a byproduct. Reduction measures are particular the type of motor used in the fan, but I would start with a snubber network

I appreciate that you use every part of the animal I would hunt for food too if I lived in a different area. Nevertheless, I get enough game, albeit not deer, I often pass a road where animals (mostly ducks) are killed by cars and as I pass by daily, I know if one is fresh.And ah yes, the usual reactions of people loathing what you do.

So what would I now chose?Well I am very happy with the two capacitive probes I have, but I am also very happy with the resistive probe opamp version, as well as with the resistive one that is being read by an Attiny85.But all in all i have chosen for resistive probes with addition of some hard/software that will cut off the power to the resistive probe for most of the time and only switch it on for the few ms that I read every 4 hrs. Does wonders for the metal of the probe.Given the fact that resistive probes actually measure molecule concentration rather than true humidity, if I were a commercial farmer I probably would opt for both, just to be able to get some feedback on the fertilizer I might be adding.As it is, both types of probes have given me satisfactory results.Currently I have changed my irrigation set up. Irrigation is now triggered by a combination of soil measurement, temperature and weatherforecast. I measure all my growbeds with 2 pcf8591 ADC's, use the mean to establish if dry or not and use the individual results to reduce or increase irrigation to that specific bed.

Space enough to screw a piece of aluminum to the back of the regulators.You could indeed do with 1 diode if you put it before the switches. No need for a Schottky diode: the LM linear regulators are not the most efficient anyway so I wldnt bother with a Schottky, unless your input voltage was just above the LM's treshold

    Your English is quite OK. If your heather does not have any transformers or electronic circuits in it but is s pure impedance load, then I do not foresee any problems Another possibility is to feed your heater with AC and use a TRIAC with zerodetection optocoupler and send it a full sinus. Ergo, switch the heating on and off, but in the on phase send it a full sinus wave

    Great. Thanks for info. Can you perhaps say exactly which LEDs you used? (brand, type)

    No surprise the fuse gets destroyed as there is a surge on the Electrolytic capacitor. Although I am not sure why you want a fuse there.. you may try a somewhat heavier fuse and/or a 'slow fuse'.What exactly made you think of 3MOhm resistor? Your circuit will not work anymore then. It will take about 15 min for the capacitor is charged then.When I designed this circuit I was going for a very fast switching circuit. That is why I put the 100uF capacitor in the main line, so there wouldnt be a delay in charging it.Now suppose you would put that 100uF between gate and source. If for arguments sake we want to load it to 15 Volt and your rectified grid voltage is 220 Volts (it isnt but just for arguments sake). Then your charge time would be 700mS or 0.7 secs.

With a 47uF capacitor it would be 0.332 seconds.The main problem that you have then is that the MOSFET will remain longer in its resistive phase, rather than be either on or off.That has 2 consequences: there might be some flickering and your MOSFET might get warm.So, could you replace the 100uF capacitor with a 47 uF capacitor over the Gate line......... Yes, i think it might be worth trying.... but keep an eye on your MOSFET and check if it doesnt get too hot (pls remove the connection to the grid before you check the temperature).I would be interested to hear your results

    Arduino Controlled Light Dimmer

    Sorry about your trouble. Let me begin with stating the obvious: in a correct circuit, your gate resistor shouldnt burn. I think I had a quarter or half watt resistor and it really shouldnt burn.So... there is an error in your circuit.I can see of only one reason why that resistor would burn out and that is if the full grid voltage would be over it.and there are basically two reasons for that:1-you somehow made a wrong connection with your triac2- your triac is faulty.Ofcourse nr 1 can lead to number 2.So I suggest that you check and double check your wiring. Have you identified the legs of the TRIAC correctly?

    AC PWM Dimmer for Arduino

    Hi, PWM indeed seems the most suitable for PID. You are aware of the Arduino PIDlibrary I presume? (if an arduino is what you plan to use)http://brettbeauregard.com/blog/2011/04/improving-...Whether my circuit is suitable ofcourse I cannot garantee but if you want to keep things simple, yes I think it is useable. Ofcourse you do still need a temperature sensor.Thereare various pid controllers on the market, such as e.g. a sous vide, but I am not aware of any commercial product for the arduino or other microcontroller.Technically I could build it for you but I am afraid that would become too expensive for what is in fact a fairly simple system that you could easily put together yourself.Yes, you were very clear. Thank you for your interest and goodluck :-)

    Thank you

    first my congratulations that your comment is nr 3333 :-)With regard to High current, you also need to consider the thickness of the coppertraces on the board. It is best to solder a piece of thick wire following the traces towards the TRIAC.The zerocrossing as wel as the arduino are susceptible to spikes. Make sure your 5 Volot is a clean one.Your wish is my command, good luck and success with yr eoy project ;-)

    Depending on how often the heater is expected to need to be turned on, I'd say that switchingit fully on and off would be a better way and certainly easier in software. In that case take an optocoupler with zerocross detection so you will switch on the load at the best moment of the phase

    my pleasure, good luck
