Review: IFixit’s FixHub May Be The Last Soldering Iron You Ever Buy

Like many people who solder regularly, I decided years ago to upgrade from a basic iron and invest in a soldering station. My RadioShack digital station has served me well for the better part of 20 years. It heats up fast, tips are readily available, and it’s a breeze to dial in whatever temperature I need. It’s older than both of my children, has moved with me to three different homes, and has outlived two cars and one marriage (so far, anyway).

When I got this, Hackaday still used B&W pictures.

As such, when the new breed of “smart” USB-C soldering irons started hitting the scene, I didn’t find them terribly compelling. Oh sure, I bought a Pinecil. But that’s because I’m an unrepentant open source zealot and love the idea that there’s a soldering iron running a community developed firmware. In practice though, I only used the thing a few times, and even then it was because I needed something portable. Using it at home on the workbench? It just never felt up to the task of daily use.

So when iFixit got in contact a couple weeks back and said they had a prototype USB-C soldering iron they wanted me to take a look at, I was skeptical to say the least. But then I started reading over the documentation they sent over, and couldn’t deny that they had some interesting ideas. For one, it was something of a hybrid iron. It was portable when you needed it to be, yet offered the flexibility and power of a station when you were at the bench.

Even better, they were planning on putting their money where their mouth is. The hardware was designed with repairability in mind at every step. Not only was it modular and easy to open up, but the company would be providing full schematics, teardown guides, and spare parts.

Alright, fine. Now you’ve got my attention.

Update Your Chinese Radio Without The Pain

August 13, 2023 by Jenny List 44 Comments

The new hotness in cheap radios this year has been the Quansheng UV-K5, a Chinese handheld transceiver with significant RF abilities and easy modding. The amateur radio community have seized upon it with glee and already reverse-engineered much of the firmware, but flashing the thing has always required a minor effort. Now thanks to the work of [whosmatt], it can be flashed with little more than a web browser and a serial cable.

This feat was made possible through the magic of WebSerial, a handy feature that allows web applications to talk to connected hardware. We’ve seen it in action a few times in the world of badges, and as browser support for it has improved it’s now available through browsers on all the major platforms.

The web app allows tweaking of the Quansheng settings and will, no doubt, be capable of uploading that when fully open-source firmware is available. It should be of great interest well beyond the world of Chinese radios, though, because we’re guessing there are a lot of projects that could benefit from such a ubiquitous interface tool.

If you’d like to know more, WebSerial is something we’ve looked at in the past.

WebSerial: Browser Based Development For Your Boards And Electronic Badges

March 21, 2021 by Jenny List 9 Comments

For years, one of the most accessible and simplest-to-implement methods of talking to a dev board has been to give it a serial port. Almost everything has serial in some form, so all that’s needed is to fire up a terminal. But even with that simplicity, there are still moments when the end user might find a terminal interface a little daunting. Think of a board aimed at kids for example, or an event badge which must be accessible to as many people as possible.

We’ve seen a very convenient solution to this problem in the form of WebUSB, but for devices without the appropriate USB hardware there’s WebSerial, an in-browser API for communicating with serial ports including USB-to-serial chips. [Tom Clement] argues that this could serve as the way forward for event badges. Best of all it can be a retro-fit to enable in-browser development for older badges or dev boards with a serial port.

The boards on which he demonstrates the technique are the series of event badges running the badge.team firmware platform including his own i-Pane from CampZone 2019 and going right back to the SHA 2017 badge, but there’s no reason why the same technique can’t be extended to other boards.

There’s a snag with all this though, sadly only browsers in the Chrome family support it at the time of writing, with no plans from Mozilla and apple, and silence from Microsoft. So things look likely to stay that way. It is however inevitable that in time there will be commercial products taking advantage of it via the use of cheap USB to serial chips, so perhaps the case to incorporate it will make itself.
