NEW Player/Amp Board For One-Button Music!

[@Bobby12many]

Great project video. Seems like a fun project for the basement bar!

[@zarboaudioprojects1430]

It would be perfect for that! Something for fun and for the look of it, however you wanted to build it. Thanks for the comment.

Sweet! A new Zarbo Video!

[@zarboaudioprojects1430]

'Bout time, right?

[@danrussell9357]

Liked the video. Please make one for the spectrum analyzer.

[@zarboaudioprojects1430]

Done. check it out!

[@hughjanis4555]

Would be interested in the potentiometer details for sure! I love these little projects.

Here is a link to a high powered one PE sells: www.parts-express.com/L-Pad-100W-Mono-3-8-Shaft-16-Ohm-260-261?quantity=1 and here is the lower powered one I used: www.parts-express.com/L-Pad-15W-Mono-1-Shaft-8-Ohm-260-250?quantity=1 If you plan to really use it as a way to go from nearly quiet to loud, the higher powered one should be used, if you just want a little bit of attenuation available, then the lower powered one should work fine.

Here is a 50 watt unit also from PE: www.parts-express.com/L-Pad-50W-Mono-3-8-Shaft-8-Ohm-260-252?quantity=1

[@jeffbaker8808]

Yes, a video on spectrum analyzer would be good!

[@zarboaudioprojects1430]

You got it!

[@GregoryDorsey-x6o]

Mr. Zarbo you put alot of work i to your videos. We all would hate to see you go. Hopefully you are one video away from blowing up.

[@zarboaudioprojects1430]

Thanks for the encouragement.

Great video Tom

[@zarboaudioprojects1430]

Thank you! I'm glad you liked it. Thanks for commenting.

[@brianraulerson5037]

I want you to camp out in my garage for 2 weeks and leave me a list of projects I need to do with all of my stuff. I will leave an inflatable mattress and a can of spider spray. Oh, there is soda in the fridge and I can leave a pack of hot dogs as well.

[@zarboaudioprojects1430]

Thanks for leaving the spider spray, I hate spiders!

[@goodgoat3096]

This is a great project! Don't even think about not making videos, PLEASE?

[@zarboaudioprojects1430]

Thanks!

[@GregoryDorsey-x6o]

Maybe speaker plan sales or member subs could be a way forward.

[@zarboaudioprojects1430]

Good ideas... I'd be happy with just having more of a reach even. I'm glad if even a few hundred people find these videos informative or helpful, but a few hundred thousand would make the work feel more rewarding.

Is the lamp out connection active all the time when it has power? Or does it just turn on when triggered? thx

[@zarboaudioprojects1430]

I have not tried that connection, but if you check the link and read the description, it may describe how it works. I don't have one handy to test at the moment.

Hi! I'm wirelessly extending my old school pull doorbell to upstairs using Zigbee (door switch attached to the pull rod, that will activate a relay connecting the switch pins to ground on this amp board). I haven't been able to decide on a driver yet though. The driver you used is a 8 ohm 20w woofer right? Can it get loud enough for a doorbell? Or would you recommend something else? Thanks in advance!

[@zarboaudioprojects1430]

I used that driver because I had a lot of them, but you could use a 4 four ohm driver for more oomph. A pro sound driver 5 to 8" would be about perfect, they like playing loud. Thanks for watching!

[@Danieldt1391]

@@zarboaudioprojects1430 I bought some cheapskate drivers off of Ali (only €1 for a pair using a welcome deal). I don't need the best of the best sound quality, they just need to get loud enough to be clearly heard throughout the top two levels of the house. There were two versions: 10W 4R, and 10W 8R. I'm guessing a 10W 8R (the ones I bought) should give more oomph without distorting than a 10W 4R, right? With a pro driver, do you mean something like the Dayton Audio PRO-8? And 5 to 8" would be too big for just a doorbell, no? I found some doorbell teardowns, and they all have tiny drivers in them, probably between 0.5w and 2w, but I want a smidge more than an ugly, crispy, ding-dong sound. The ones I ordered are 2" drivers.

[@zarboaudioprojects1430]

@@Danieldt1391 Generally speaking, a 4 ohm driver will play louder per a given watt than a similar 8 ohm driver, but it does depend on the driver. I suspect the drivers you picked will work fine for what you're wanting to use them for. As long as they are in an enclosure, so the front and back waves don't cancel each other out, I bet it works fine. I only suggested a pro-sound driver because they are sometimes more efficient than home stereo drivers. But since you already have the drivers, I would just go with them. An average doorbell chime will be between 75 and 85 decibels, and your driver should easily be able to do that, so I think you're good.

[@Danieldt1391]

@@zarboaudioprojects1430 Hmm you're completely right, I didn't think about it like that. I thought that as the resistance would be doubled, I could crank the amp twice as high; but yeah they're both rated at 10W... There's some reviews saying that they can't even drive them that high though, so it could still be that in reality the 8 ohm takes more watts than the 4 ohm version. It should arrive in a few days; I think it should still be good enough, if not I'll continue the search. Thanks for the help!

[@Danieldt1391]

​​@@zarboaudioprojects1430 I finished the build last week. Everything's working fine and dandy, and I found a perfectly fitting wooden box for it (This board, a Zigbee smart-home relay switch, two 2 inch drivers, dc plug, all within 18x8x5cm / 720ml) I guess I might've made the right choice on resistance after all. I ended up using both 8ohm 10W drivers, and wired them in parallel, resulting in 20W at 4 ohms. If I had two 4 ohms they'd have to be wired in series because in parallel the resistance would become too low, but then it would be 20W 8 ohms. This would then give the dual 8ohm 10w setup the edge in terms of oomph over a dual 4ohm 10w setup, no?
