Post pics of your builds.... - Page 360

My word, what pretty boxes!

I bet they get even prettier when you turn them on

Those betas are freakin' amazing!
I love your front panel design, simple but elegant.

Looks nice, congrats. Now what about shots of the B24

Here is my latest "re-house a Class D" cheap amp project.







I've posted an in-depth article with loads of pictures and ideas so if you are looking to put something fun into an enclosure, give it a look:

Let's Build a Class D Amplifier!

Happy Wednesday!

that is insane, 2 b24s?

nice write-up, dano.

I also have one of those class-D amps. I should case mine up, too. mine was $15

qkizz's β24s are monoblocks -- a separate chassis for each channel.

qkizz, I like what you have done with the front panel. By using a smaller bit of metal for the odd shaped bits and logo it keeps the costs down and saves doing the whole front part.

is that power connector a 1/8" audio jack??

tell me it isn't.

Yep, but it is there because I didn't have enough room to do my standard kobiconn insulated part.

you do realize that if it comes out while the power is on, its *shorting* right?

audio alchemy designed gear like that. not a good idea, especially on production gear.

I would really suggest getting a non-shorting barrel style connector.

Yep, as mentioned I nomrally use plastic kobiconns. On this particular build, I underestimated the part size when I drilled the back panel. Rather than scrap the enclosure, I decided to forge ahead with the parts available. I actually pull the wallwart out of the socket before switching of before unplugging. As for production gear, I've built 20-40 unit runs of guitar effects before, so I wouldn't take that shortcut on a production unit.

BTW, I've dug out my arduino and some relays, going to work pushbutton source switcher. Your pics have had me itching to go back to MCU stuff for a while...

Hello everyone,

I just wanted to say that seeing all these pictures and reading about everyone's projects is incredibly motivating. I'm pretty much just starting to get into these kind of things and it is awesome that so many people are this talented at it. Hopefully before too long I'll have something of my own to share.

i'd suggest u start with a cMoy amplifier. you can get all infos u need here: Tangentsoft Lookin' forward to see ur first project.

2 'mad scientist' (bwahahaha!) pics showing a test bed, quite unfinished, but slowly getting there:





trying out a slightly different take on the old relay attenuator thing. and trying to keep the software so that it works for both the PGA style volume control chips as well as relay methods. I'm trying out 7bit relays here, so that goes from -127db to 0. the PGA chip 'only' goes from -95db but also gives gain and goes to +31db, if called upon.

this was a lot of soldering, these 2 boards. I would not recommend this (lol). but it also gave me some insights on trace layout, so it was not a total waste. sometimes you can really appreciate some geometry or layout when you've had to manually solder things over and over again

like this:



lol!

again, not recommended. it was very frustrating trying to solder this.
