Is the reason a buck converter is required so that it can increase I? I = V/R, by increasing V we can increase I?

I suspect the usb-PD standard doesn't allow for raising the voltage any more than they already do

PD with EPR can go up to 48V, 28V support is common-ish.

It's cheaper and easier to get a USB microscope and look at a laptop screen than to peer through a binocular microscope. I've used only lead-free solder for a decade. Get the good stuff with some silver in it and it's not difficult.

I usually use my phone zoomed in + flashlight in video recording, and an external macro lens. It probably isn't as good as a usb microscope, but it works really, really well. Looking at videos of people using microscopes, the quality seems to be on-par or worse than my phone.

Can you recommend a macro lens to use?

Do you have plans to have an actual local application to do this? Chrome-only web tools are not sustainable and a deal breaker.

As noted in the article, there's also a traditional serial interface.

In that case, an Arduino + touch screen would be a nice little addon for this.

That looks like something I'll get. I have a very primitive old iron (and a gun, which I seldom have a use for).

I've been thinking about it as well, as I wanted to upgrade mine, but I think I'll go with a Pinecil that costs 25$...

I am completely confused by your example. Buying a better knife doesn't make you a better chef. Buying a faster car doesn't make you a better driver. Buying a more powerful laptop doesn't make you a better developer.

Do you cook? There are dozens of obvious examples. A crappy knife will tear instead of cut. You'll ruin tomatoes, have uneven dices, crush and smear delicate herbs, have ripped apart meat and fish that you'll destroy more trying to get rid of the trim. That's not counting the downtime you'll have when the knife slips instead of cuts and you can't cook at all due to injury. Giving an expensive knife to a new cook that…

I cook, and I disagree with the assertion that a better knife makes you a better cook. Good knives are useful, but ultimately you're still going to produce crappy results if you're a bad cook with a good knife.

I think for simple through-hole stuff, this should be fine. However, so much stuff now requires SMT reflow and a hot air wand (and likely a binocular microscope) that except for home builds and power electronics, I rarely use an actual iron. As you say, it's so much easier to get good solder joints (especially for the fine stuff like QFN/BGA) with lead blends and flux, that having a vent hood is likely required as we…

I find the lag to be murder when trying to solder very small things. I can use a USB microscope in a pinch, but it makes me miserable.

As a gamecube controller modder who uses a TS101 on the go, the handle isn't such a bad deal. I paid the same price for the TS101 bundled with a barrel jack power supply that I never use. The short tip-to-grip distance seems nice, and the higher power is good. But the full station price is kind of outrageous. I got my Thermaltronics TMT-2000S for less, and that's a monster . But then again, I don't have to use their…

Reading the description of the Thermaltronics TMT-2000S on their web page. Do you not have to set a temperature, and it just senses and figures out the right temperature?

The tip alloy is set to have one of three curie points: 600, 700, or 800(ish) °F, and the curie point automatically regulates how much the RF energy actually heats the tip.

The instant it cools down, power is delivered.

Jewler's Loupes work as well.

In a pinch, but you have to get your nose way too close to the soldering iron.

I stumped up for a set of dental loupes many moons ago and they were nice, but expensive. They're safety glasses to boot.

They're come down dramatically in price since then. https://www.practicon.com/Loupes-Magnifying-Eyewear

The cap has a magnet on it that auto-homes so that really isn't a risk.

The Power Station has a 55 Watt Hour battery, which is where most of the cost comes from. It doubles as a battery bank for your phone or laptop, or any other USB-C devices in your life.

A bad dull knife bruises and smashes more than it cuts. If a first time cook was making a salsa, the one made with the good knife would be better as the tomatoes would be juicer and not all smushed.
