Push Button Speaker Build!
Been busy the last few weeks waiting for all the parts to arrive to put together a push button speaker button. I got a lot of the help from this YouTube video
View: https://www.youtube.com/watch?v=l-fVvqQ4RgQ
it's well worth the watch and answers a lot of questions I had about the build. Lots of other questions (mainly about programming the relay (Mode P1.2 is the one you want) were answered by doc google.

I couldn't find the exact parts in the above video but managed to get close. If anyone is interested, the push button is a retro arcade button! I don't know how waterproof it is, so I bought a bunch of them and will swap them out as needed. I figure I can always put a little hood or something on the sign when I get around to it, that's future me's problem.

Parts list
DC 12V 24V 120W*2 TPA3116 D2 Dual Channel digital Power audio amplifier board
12Vto 5V DC-DC Step Down Charger Power Module Dual USB Output Buck Voltage Board 3A
DC 6-30V Support Micro USB 5V LED Display Automation Cycle Delay Timer Control Off Switch Delay Time Relay 6V 9V 12V 24V
FM Radio Receiver Module Frequency Modulation Stereo Receiving PCB Circuit Board With Silencing LCD Display 3-5V LCD Module
33mm Arcade Push Button Led Momentary illiminated Transparent Buttons with Micro Switch

Firstly I put together a test set up in the most dodgy way possible with all the electrical tape and miss-matched wiring colours. It only took me two blown fusses to figure it all out! A win in my book.

12V power is delivered by a 2pin power injection wire that will come directly off my little power distribution boxes, meaning no need for dedicated power supply in the box.

Once i figured out the amp and timer, it was trying to intergrade a FM receiver so i could have an all-in-one solution. Just give the box power and connect up some speakers. Instant party! I tried to use side cutters to remove one of the USB headers.......it did not go as planned, luckily there are two ports and I could use the other one. I ended up just soldering to the back of it, it worked much better that way. The two outside pins are + & - for those that are interested.

I have discovered that I am not the best as soldering.... I can't tin very well, and I seem to just add more solder until it sticks together.......Hopefully as I progress through this hobby my skills will improve. A better soldering iron would probably help.

Last thing that didn't really work in my favour is putting it all in this very small box. Bud Box NBF32004 - 150 x 100 x 70. It's all I had laying around and didn't want to buy another one. It fits but I had to get creative with mounting and there might be a few stray holes in the acrylic from failed mounting attempts.

But it's done! Another item ticked off the to do list! Checked it all worked with the FM Transmitter from Light-It-Up and worked a treat! Got a set of large floor stand speakers from the local Buy Nothing Page for free and ready to rock.

Very impressed with the sound level this little amplifier puts out as well!

If anyone is interested in a wiring diagram let me know!

Next job is to finish drilling the last of the holes in the electrical conduit and start pixel pushing. Hopefully can get back to that in the next few weeks!

Smaller ones were Bud boxes NBF23004 – 150x100x70 that were purchased from Digi Key.

Though I have since upgraded to a bigger box (290x190x140) as i found the smaller one too hard to fit everything in neatly.
I got these from https://www.hansonelectronics.com.au/product/box-290x190x140/

Have a read through https://auschristmaslighting.com/th...er-as-presented-at-the-perth-2023-mini.15467/ as it provides more info and details what changes i made for better audio quality.
