Any suggestion for a (reasonably) good and cheap one for new designs?

The book "Small Signal Audio Design" by Douglas Self has an entire 50 pages chapter on selecting opamps for audio. The chapter roughly ends with this quote:

> One thing is obvious — the 5532 is still one of the great opamp bargains of all time.

i like the opa2134 pa , or in general the bur brown opa, on the expensive site and on the cheap one the ne5534.

To me it sounds extremely unlikely a car with such heavy modifications would be allowed on swedish (or finnish) public roads.

Very cool project though!

I must be checking the wrong forums. Never seen it.

Ok, that's interesting to hear. More reason to spend (even) less time on Reddit and Youtube, I suppose, which is probably where I've been over-exposed to these sorts of points.

Ben Heck has done quite a few that might fit

Indeed. The local bus transit has a digital ticket system with QR codes for tickets. I haven't actually tried decoding the codes but just seeing them and interacting with them I can tell they have gone WAY overboard with either the amount of data they try to fit or the amount of error correction. Probably both. They are nearly unscannable due to their size and all the bus drivers just wave you along if you don't manage to scan it.

The second one is being completed (as far as I understand) by a team in germany at a music machine museum (Musikkabinett). Their channel: https://www.youtube.com/@Musikkabinett

True that. We are just incredibly spoiled on that part of freedom.

As I wasn't in the know (though I can guess), I did some googling as to why and found this old thread:

And also incredibly small.

Turbo Pascal 2.0 had an IDE with compiler and debugger in a binary less than 60kb (if the info I found googling is true). Of course nowhere near the capabilities of modern environments but state of the art at the time.

The debugging experience I had in Delphi 6-7 was still streets ahead of what I use today in Ruby.

Turbo Pascal 3.0 had an IDE with compiler and debugger in a binary less than 40kb (if the info I found googling is true).

And it (initially at least) cost $50 vs. a few hundred dollars for other compilers of that period, like MS Pascal.

Been working with it for the last year or so and the looks are alright but I just completely loathe the way tkinter is designed... it just feels so old.
