Bad circuit design was holding the music chip in a reset state. With the addition of a 10k resistor, the Happy Birthday tune is able to play freely.

Perhaps the original circuit was designed for a greetings card and it's meant to be activated by a photo-resistor? I dunno. I'm new to this…
replace the transistor with a FET .
Well done!
Thanks for the video. I have two nearly identical eBay "birthday" DIY kits but instead of the transistor yours has, mine uses a 9013. Mine suffers the same issue and the 10k resistor fixed my kits as it did for you. My kit can be distinguished by having a 5.5×2.1 power plug and I mention this because my kits do NOT play happy birthday even though the item listing is for "DIY Kit CD4060 Dream Light Birthday Gift Suite." Instead, they play several short snippets of Christmas music.
I think the issue is that you did not have all the other circuitry hooked up, so all the current is beating the shit out of the transistor. I bet if you had the whole board wired up, it wouldn't overcurrent like that.
Did you ever make the heart shape version of this kit,I looking for a video to watch to help my assembly ,anyone
Well, I am glad you found the fix. Last week when I saw the video where you got that kit, I thought that it would be a great kit for my niece to build. So I ordered one thinking that maybe you just had a dud. Now I know that when the kit arrives, it too will be a dud but, you have found the fix. So thank you from myself, and my 14 year old niece who has recently become interested in Arduino and small electronic kits.
You need to do the rest of it!
If it was being reset then why did the other speaker work?
Great tutorial, I new you would sort it out, How did you know to use a 10k? Thanks John 🙂
Hello, i have been watching you for a while, But this is my first comment. Was wondering if it is possible to change the music to something else or would a different board be better? I want something cheap, more or less prebuilt that can be put into a toy to add lights and sounds to it.
Brilliant debugging! Thank you for explaining the solution Julian!
Now how do you get inside a card?
Nice work!
I think this thing was designed that way. They were hoping that the draw from the leds would lower the voltage enough for the chip to function.
Could there nor be a resistor in the chip? And maybe it's just faulty? Too much tolerance?
Oh my god its my birthday today!
All I can say is "Wow"….
