Saw this video a few months ago, ordered the LM567 from China, which took a couple months to arrive, got the order and put aside for awhile. Finally today, I tried your circuit out. Did not work the first time, but I eventually figured out the microphone was picking up way too much noise off the 5 volt supply. So I changed the microphone to the 3.3 volt supply, left the rest of circuit running on 5 volt and it worked great. So now realize I should have hooked the microphone up to my portable speaker first to make sure it was working good, before trying it in a circuit. Thanks for the video. I will hopefully get around to building a more permanent version of this circuit, after I experiment a little more with it. Am going to see if there is a way to control the detection frequency using a variable voltage from a microcontroller, rather than the potentiometer.

Thanks for this video, I'm returning to amateur radio after a 31 year break and this well produced video has been both educational and inspired me to have a crack at morse. 73 G6XIB.

Hi Coldestmoon. I was wondering if you could use a similar circuit to trigger an audio alert. I have a long driveway and my elderly father is hard of hearing. I was hoping to make something that alerted him specifically of my return home. He's into amateur radio and loves morse, and i thought it could play my initials (I E) when I triggered the sensor. It takes me a full 21 seconds to get up the driveway, and he's usually got his music on loud so I was hoping to interrupt that too. He'll have the bass kicking and the drums drumming, and when he hears "ditdit dit" i'm coming. Would that work? Thanks.

Great vid's Coldestmoon! Just saw your "CW-Trainer kit"and "CW Decoder" video's, well done! 2 questions: 1) Have you been able to upgrade the CW-decoder PCB in the meantime and if so, can I order one from you? As a recent Ham, I would like to start learning CW but don't find it so obvious, so your solutions would be a great help. And2) As a Arduino "Newbie", is it possible to combine both programs (trainer and decoder) on one Arduino ? (I don't think so, but ask it anyway). Thanks Dan. 73.

+Sven Vyncke Hi Sven. Many thanks for your comment. Yes i did fix the issue on the PCB - it was 100% my own mistake. To learn CW - you really need to learn the code. Start simple by going to lCWO.net and start with just a few letters and build up over time. Currently the 2 sketches for the Arduino are a bit big to squeeze on 1 chip. I am working on a total solution version - but nothing at present. I hope that helps, any questions feel free to ask. 73. Dan

I have a question about this circuit.. I'm fairly new to tinkering with circuits.. am I ok using non polarized caps (wima) in this or do the electrolytic make a difference? thanks for your help! can't wait to get mine up!

+MrLovelog Hi, thanks for your comment. You could easily use ceramics for this circuit - In fact the 3rd iteration of this photo type was all ceramics, with just 1 electrolytic. I hop that helps. 73 Dan

What is the purpose of the LM567 chip?
@ColdestMoon_Channel
8 жыл бұрын
+Tommy N Hi Tommy, The LM567 is the tone decoder. It converts an audible tone into a digital signal (on or off etc) that the Arduino can understand. The Arduino then uses this on-off signal to figure out what the character is, then display it on the LCD. I hope that helps, if you have any other questions feel free to ask. Dan

+ColdestMoon Thanks for the quick response. I am building this device. Great video btw, very clear and steady camera work. However, I must ask now, I have seen this device built without the LM567 in other plans. In fact, I built the simplified version you can see on the internet without the LM567, with just the resistors and capacitors and the led lights up when I put audio CW morse to it. Does the LM567 make the signal better than without it or something? Thank you.

+Tommy N Hi Tommy, to be honest I'm not sure how it would work without the LM567. i haven't seen any plans or versions of this without it. The chip in essence creates an open or closed circuit based upon an audio tone fed into it. So a mic would suffice as the input. If you do have plans for it without the chip, i would be very interested to see how it is accomplished - and if you're running a version without the chip please do let me know the circuit. Many thanks Dan

+Tommy N Brilliant - thank you. So to answer very quickly why use the LM567 - you can choose your centre frequency without adjusting code, it also removes any noise and equalises the input. So the signal will always be the same HIGH / LOW. The detecting and decoding of the audio is in the chip. This sketch looks great - as you will see in the comments of it, you can adjust the code for equalising weaker or stronger signals & swinging the centre frequency. Thanks Dan
