The first thing you're going to need is a really good soldering station... like a Weller.

Thanks for the suggestion. I bought a cheap one years ago but I suppose if I am going to jump in with both feet, I'd better use good tools.

I would mind "getting my feet wet" with some type of DIY project involving a soldering iron but I don’t want something that I’ll regret having later (as DJL pointed out).

...Building a device from a kit that walks you through everything is also appealing. Especially if it’s written for a beginner and that I have a very small chance to screwing it up.

You're sort of between a rock and a hard place. There aren't many kits for high end equipment, and they have more expensive parts and more difficult construction and more reliance on your prior experience - not for a beginner. The beginner quality kits are not for a top of the line device. That's why I suggested you look for something on the PAIA site that you can use - not necessarily a preamp, though their tube preamp looks interesting- and build that to get a good foundation of skills and familiarity with parts, etc. Then with that confidence you can move on to something more complicated.

Maybe you right. Get my chops on something easy and then move on. (In all likelihood I’ll get the DMP-3 anyway and have the DIY preamp for a different color).

Thanks for the suggestion.

Oh good grief lol. I specifically asked if this was hard to do earlier on in this thread and I was told it wasn't lmao.

It *is* really easy. Sounds like you got the SMD version of the chip, though; hopefully the other one you're getting is the 8 pin DIP version. I've built this from the app notes, and it works just fine. I didn't use the servo option in mine though, you just take pin 5 to ground instead of to the output of the servo opamp (just like it says in the app notes.)
 
As long as it doesn't require a lot of parts, I can't see it being that difficult. I know the cheaper stuff isn't really electrically complicated, and that is the kind of thing you do with the INA217 chip, right?

All I really care to do is make something, say, better than an Audio Buddy, but for a comparable amount of money, just so I can get into this type of thing, and save a little while I am at it.

Flying an airplane, driving a car, preparing a meal, writing a sentence, not wetting your bed - they don't seem that difficult to do either - until you try it for the first time. There are some things in life you have to learn if you want to do them, and building electronic equipment is one of them.

Your posts reveal that you don't have the first clue about building an electronic device. This is nothing to be ashamed of, but you need to realize that if you want to do this you will have to take it a step at a time to learn how to do it, and you're not going to build something better than an audio buddy (which has fairly involved circuitry BTW) from scratch without learning how to do it with simpler projects first, or a kit that has everything laid out for you a step at a time, with copious illustrations and explanations along the way.
 
You're probably, right. It's hard to remember what it's like starting out. But if you've got any experience throwing stuff together from a schematic, this sucker is a piece of cake.

Yes, you're going to need good tools... and after learning how to solder, your going to need to learn how to do identify parts and their values.

DJL,

When you refer to "parts and their values", are you saying I need to be able to recognize a resistor from a capacitor and a being able to recognize a high quality capacitor from a low quality capacitor? Or do you mean recognizing a 1-ohm resistor from a 5-ohm resistor? If memory serves me correctly, I believe they are color-coded and their stripes indicate which is which. Probably a good book would also help as a reference.

JohnnyMan, if you don't know what Phyl is talking about in his above statement... he's showing you a good way to remember the color code.

Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Gray, White. ;)

Thanks. The funny thing was I did know what he was referring to but I couldn't remember what the acronym was.

My 100th post!!
