@ElecNotes Baofeng has the UV-5RM now, by the way. Similar price point and similar performance to the TD-H3. It still needs that darned FTDI adapter to program, though.

Watch Out - There’s a New Ham Radio HT!
For years, the Baofeng UV-5R has been the undisputed king of budget handhelds. But it’s starting to show its age. After putting the new TIDRADIO TD-H3 through its paces, I think we finally have a "Baofeng Killer" that brings modern, professional utility to the budget price point.
In my latest review, I explore why this compact dual-bander is rapidly becoming the go-to choice for Hams, hikers, and SOTA/POTA enthusiasts.
Here are 3 reasons why the TD-H3 stands out:
✅ Revolutionary Programming: Forget hunting for specialized "K-plug" drivers. The TD-H3 features native Bluetooth for field programming via your smartphone and a direct USB-C port that handles both charging and data (CHIRP compatible!).
✅ Superior Display & Build: It’s more compact than the UV-5R but feels significantly more solid. The 1.44-inch color TFT display is vibrant and high-contrast—a massive leap forward from the dated, segmented LCDs of the past.
✅ Better Receiver Performance: While it’s not a high-end Icom or Yaesu, the TD-H3 handles local interference and "de-sensing" noticeably better than its predecessors. Plus, the AM Airband reception is surprisingly clear.
The Verdict?
If you’re looking for a "glovebox" radio or a reliable hiking companion that doesn’t feel like a toy, the TD-H3 is arguably the best value on the market today at the $30–$35 price bracket.

@NelkuCosplay Wait!? You're not spiderman??? I think I have pictures somewhere that dispute this.

@ElecNotes Ah; the beauty of band-gap references! These little guys were the heart of my linear power supplies for devices. Controllable ripple, works over a large range of currents, etc. SMPS excel in the world of small, but you constantly fight them.

Are the 7800 Series Regulators Still Relevant Today?
The 7800 series voltage regulators are arguably the most iconic linear regulators in electronics history. From the 5V rail in a hobbyist project to the 12V supply in vintage industrial gear, these three-pin wonders have been the go-to solution for decades.
They are widely available from many sources, so they can still be a good choice, despite many other newer designs.

@Zinny_Edmund Don't learn languages; that is syntax. Instead learn concepts and patterns - those are more important.

@TrisH0x2A The fact that it is so easy to develop on one computer and deploy/build on target hardware is what makes me keep coming back. The others just aren't as easy.

@ChessJoscho @TrisH0x2A 98% true; POSIX did change some of those Unix syscalls back in the 80s by deprecating them and things like standardizing the 'undefined' behavior like errno returns. But that is a super detailed view. UNIX from Bell Labs, made back in 1969 is basically what we use today!
English

@_rish11 @TrisH0x2A Completely agree - but the syscalls in the example already existed back then 😄

@NelkuCosplay Are you just using your phone? I find the depth of field interesting on these photos Nelku

@ChessJoscho @TrisH0x2A True; but Unix isn't Linux as it is today. Having taken those Unix classes back then I can appreciate this.
