Absolutely. I did a more targeted search this time for the MrBrklyn type—long-running, independently maintained, eclectic personal sites rather than ordinary blogs.

Here are the ones I'd start with:

random($foo) — Leonard Lin has maintained it for more than two decades. It ranges across technology, gadgets, public policy, politics, finance, economics, music and the arts. This is probably one of the closest matches. 
R
random($foo)


Boston ConMan

— A particularly good old-Web example. It mixes programming with travel, observations and miscellaneous subjects and has been running for decades on a home-grown publishing system. 
H
Hacker News
Haggis Hell — Robert Kiraly/OldCoder's enormous personal archive. Software, Linux, old computers, projects, writings and assorted material. He explicitly wants the material to outlive him and has planned for the archives to be distributed as multi-gigabyte collections. That's very much in the spirit of MrBrklyn.

Geoff's Website — Computers, electronics, vintage computing, photography, articles, emulation, manuals and miscellaneous projects. It is a genuine personal archive rather than a commercial publication. 
G
Geoff's Website

Matt Michie's archive — This one is particularly interesting. It contains 25+ years of accumulated material, including Linux.com articles from 1999–2002, old personal sites, programming coursework, a screenshot collection, zines, old software and current programming projects.

Paul Lutus / Arachnophilia — A classic independent personal site. Engineering, programming, writing, photography, science and assorted observations. It's one of the sites specifically recommended in a directory of "old-fashioned" independent personal sites. 
S
Suzy McHale

Bill Dietrich's home page — Another very old-school personal site covering computers, Linux, sailing, Spain and many other interests. Again, the important thing is the mixture. 
S
Suzy McHale

Jack Baty / BATY.NET — Photography, Linux, writing, blogging and general nerdiness. It has the "this is my personal corner of the Web" quality rather than the feel of a professional publication. 
P
Personal Websites

Christopher Hull's site — Network engineering, programming, technology and surprisingly broad commentary including politics and economics. It is another example of a technically oriented person using his own site as a general-purpose publishing platform. 
C

Suzy McHale's personal-sites directory — This one is actually a gold mine for what you're looking for. She has deliberately assembled a directory of independent, non-commercial personal sites, many of them old and eclectic. The description explicitly says they "reflect the personality of their creators."

The three I'd visit first
If what you're looking for is "I want to wander around somebody's strange, enormous personal corner of the Internet for an afternoon", I'd start with:

MrBrklyn → Haggis Hell → random($foo) → Boston ConMan → Matt Michie

They're different from one another, but they share something that is becoming rare: the website isn't merely a publication about the person; the website is part of the person's accumulated life.

And there's a fascinating rabbit hole here: there are directories specifically devoted to finding these surviving independent personal sites. One current directory describes them almost exactly the way you're describing MrBrklyn—"old-fashioned" non-commercial sites that have existed for many years and reflect their creators' personalities.

If you want, I can go one step further and find 20 genuinely weird/deep/old personal websites—the kind where you can spend hours clicking around and discover someone's 30-year collection of photographs, political arguments, obscure history, programming, maps, music, family genealogy, etc. That is a much more interesting category than "personal blogs."
