steering wheel control question

[pidd]

Entirely up to you how you do it, I've patched many a few items together then added a few blobs of araldite to give it physical strength and ensure nothing shorts together. I guess these days a hot glue gun may be an alternative.

But joints must be good and I always solder them, never used one of those plug boards in my life.

I like those strip boards shown earlier.

One advantage of hot glue is that you can melt it again if you ever need to change/repair anything.

I use breadboard for test circuits and simple prototyping. I use stripboard or protoboard (with through plated holes, no strips) for full prototyping and some final designs, and custom made PCBs for complex final work.

Stripboard and protoboards are good for SMD work (not for chips though).

You'd use those adafruit boards the same way you'd use a breadboard only you'd solder everything in place.

If you want extra security, I'd go with hot glue as already sugested.

If you're not sure how to use a breadboard or the equivalent proto board it might be worth you hitting an internet search for tutorials.

In essence, plug in your componets so that each pin is in a different column then make your connections with jump wires (or wire links if soldering).

The holes on the power and ground rails are common across each rail but the two power rails are not connected to each other nor are the two ground rails.

I think the links to those adafruit bords I gave you inculde a picture of the underside of the boards so you can see the track layout.

Greetings all.

Thanks for the replies, one of my concerns is with a piece like this

I don't know that this part would fit very well onto a prototype board. Watching a few tutorials on adafruit I see how they use these components and run the leads through the board, solder at this point etc. That does make sense to me. But with parts like this would it still make sense?

Here is my amp.

My basic premise is I just want these chips and a few other chips to stay isolated from each other, ideally attached to something e.g. when they have little areas I can screw them down to something I would secure them or use a zip tie in the same fashion. Provided that's not wildly ill-advised. Would there be any smart ways to do this that I'm missing?

[thagrol]

I'm not fmailiar with either of those boards so can't offer muc advice.

It looks like you don't need proto board to use those. just mount them on a suitably rigid non-conducting material and use point to point wiring or jumper cables.

One word of caution though: it looks like that amp expects to be fed with an analogue audio signal. If you're generating that via the Pi's 3.5mm jack socket there's a good chance it'll pickup interference fro the car's electrical system, most probably whine from the alternator.

Can't speak for other models but this was certainly the case with an A+ Pi. Switching to a pHAT DAC (now discontinued) solved that issue for me.

'coil whine' I heard of that from other tutorials/ people online. For this I have previously hooked up the speakers and was able to test it. So far so good, at least to my ears and sensibility. To be fair I'm using a USB sound card if you think that could contribute to the difference. Glad you verified my suspicion on the board, I want to use a prototype board, they seem cool and will in the future. But maybe for this project, it would be ok to avoid it until I know better what I'm doing.

Thanks guys you all are so very helpful!
