I just bought a similar kit. I have never done this before, so this is my very first one. Your video was exactly what I was looking for. Thank you so much!
I find that if you use a flux pen on the pads it makes a huge difference. I think these kit pcb's must lie in warehouses for a length of time and the traces oxidise over!
I'm also cleaning off the board's pads with isopropyl alcohol prior to soldering. It's true that electronics can get stored for long periods of time and in non controlled humidity. I've had rusted parts...
Not any direction, no. These PCB switches often have pairs of legs joined together, so if in doubt use a multimeter in continuity mode to check which connections are made when you press the button. You can normally tell from looking at the PCB which contacts need to be bridged to switch it on.

Hi there! The shorter leg always the negative side of the LED.
These are just bits of wire from my own box of wires. The markings on the board look like some kind of power connector can go on there (e.g. a molex 2-pin socket), but no connectors were supplied with this kit.
@@MartynDavies ahh ok any idea on a connector that may work? I may buy that 500 port connector from Northridge fix and see what I can do with that. But thank you for this guide I actually soldered a peice backwards lol 🤦♂️but fixed with some flux and nice wick.
@@MartynDavies thank you I'll see what I can find with this I also got some cell battery connectors coming in with leads so can tin wires and solder em on also I will change the tip I used a very fine tip better to use the other bigger tips. Thank you for clarifying the resisters as well I didn't know the values of them.
I have a wee Maplins led tester but, to be honest, I find the quickest way is using a suitable button cell between the legs! The led legs, not mines! ;-)
hi M D... ' can this electronic capacitor change any number uF and less 50 volts in the color breath heart electronic kit... i have good LED electronic kits / projects in my channel

I'm 7 y.o. and uploaded video about same kit soldering today. And I like your nice, tidy soldering :)
Thank you. I've been practicing for many years :)

It occurred to me afterwards that a wipe with isopropol might help also

Thanks!
You could put it under a white shirt as a Valentine's surprise for the wife!
Iron Man!
I built 2, without success. Is the 6 pin power button, reversible? Meaning, can you put it on the board in any direction?
Not any direction, no. These PCB switches often have pairs of legs joined together, so if in doubt use a multimeter in continuity mode to check which connections are made when you press the button. You can normally tell from looking at the PCB which contacts need to be bridged to switch it on.

Hi, what's the red and white wire at 21:31 called? I don't see it in my kit, am I supposed to buy them in order for the kit to work?

hi M D...
i have 2 LED heart kits HBL-22 with color LED heart project...
both kits are not need two R5 resistors
Any ideas on how to power this other then a voltage injector tool? Got a few of these for stocking stuffers.
It needs something close to 4V to work properly, so perhaps a well charged Li-Ion battery? Or failing that, a couple of disc cells (e.g. CR 2016)?

@@shadowarez1337 the board I've got seems to have space for a 2-pin JST connector. These are not a bad way to get power in.

How big would the device be using full size components instead of the chip ?
The chip here (dual op-amp) is generating a triangle wave. You could do that with a discrete circuit e.g. transistors, but it would take quite a few.

I'm sure you can put a range of different capacitors there instead of the one supplied.

hi M D...
i still have very good DIY breath LM358 heart kits...
