Small portable soldering irons are all the rage so [electronoobs] decided to build one on his own. While the design isn’t quite as sleek as a commercial unit, considering it holds its own batteries, it looks pretty good.
Of course, the question is: does it work? You can see in the video below that it does, melting solder in about ten seconds. The weight is about 100 g, so it should be very comfortable to use.

Soldering requires steady hands, so when [Jonathan Gleich] sadly developed a condition called an essential tremor affecting his hands, soldering became much more difficult. But one day, while [Jonathan] was chatting with a friend, they were visited by the Good Ideas Fairy and in true hacker fashion, he ended up repurposing a handheld camera stabilizing gimbal to hold a soldering iron instead of a camera or smartphone. Now instead of the gimbal cancelling out hand movements to keep a camera steady, it instead helps keep a soldering iron steady.
While the inner workings of the cheap gimbal unit didn’t need modification, there were a couple of things that needed work before the project came together. The first was to set up a way to quickly and easily connect and disconnect the soldering iron from the gimbal. Thanks to a dovetail-like connector, the iron can be safely stored in its regular holster and only attached when needed.
The other modification is more subtle. The stabilizer motors expect to be managing something like a smartphone, but a soldering iron is both lighter and differently balanced. That meant that the system worked, but not as well as it needed to. After using some small lead weights to tweak the mass and center of gravity of the soldering iron — making it feel and move a bit more like an iPhone, as far as the gimbal was concerned — results were improved.
The soldering iron stabilizer works well enough for now, but we don’t doubt that [Jonathan] already has further tweaks in mind. This is a wonderful repurposing of a consumer device into an assistive aid, so watch it in action in the short video embedded below.

Over the past few years a new class of soldering iron has arisen: a temperature controlled iron no longer tied to a bulky mains-powered base station, but using low-voltage DC power and with all electronics concealed in a svelte handle. First came the Miniware TS100, and then many more, with slightly different feature sets and at varying price points. We’ve reviewed a few of them over the years, and today we have the most recent contender in the Sequre SQ-D60. It follows the formula closely, but costs only £20 (about $26). This price puts it in an attractive budget category, and its USB-C power option makes it forward-looking over models with barrel jacks. Description over, it’s time to plug it in and put it through its paces.
In the box, aside from the handle containing the electronics, were a surprisingly comprehensive array of parts and accessories. The handle itself is similarly-sized to its competitors, being only slightly longer than that of Pine64’s Pinecil. The tip supplied was unexpectedly a slanted chisel, so I may have managed to order incorrectly, though since it shares the same tip design as both the TS100 and the Pinecil I have plenty of alternative tips should I need one. Otherwise there was a little bag of hex screws along with a key and a driver for them, a little stand with a sponge, a set of Sequre stickers, a USB-C to barrel jack cable, and a barrel jack-to-XT60 connector for use with LiPo battery packs. These last two cables are a particularly useful addition.
At first sight the tip doesn’t seem to have any means of being fixed into its socket, but a closer inspection reveals that there is a hex screw hiding underneath a silicone finger sleeve that holds it securely when tightened. The handle has a simple enough interface, with just two buttons and a 3-digit, 7-segment display. Powering it up from a 45 W USB-PD power supply, and it heats up to 300 °C in around ten seconds after pressing one of the buttons. My usual soldering temperature is 360 °C, and it has an interface involving long presses of one of the buttons before they become up and down buttons to select the temperature. In prolonged use the handle doesn’t become noticeably warm, and aside from a slight new-electronics-getting-hot smell there was no immediate concern that it might release magic smoke.

There was a time when decent quality soldering irons were substantial affairs, soldering stations with a chunky base unit containing the electronics and a lightweight handheld iron for the work. That has changed with the arrival of a new breed of microprocessor controlled lightweight handheld irons. There’s a new kid on the block from a company we associate more with open-source phones, laptops, and single board computers, Pine64 have produced the Pinecil. It’s a lightweight handheld iron with some innovative features at an attractive price, but does it raise the bar sufficiently to take on the competition?
I put the Pinecil through its paces, and and although the device is fully open source, give it a teardown for good measure. Spoiler: it’s my new favorite.

If you’re building mechanical assemblies with 3D printed parts, you’ll quickly realize that driving machine screws into thermoplastic isn’t exactly an ideal solution. It can work in a pinch, but you can easily strip the threads if you crank down too hard. The plastic holes can also get worn down from repeated use, which is a problem if you’re working on something that needs to be taken apart and reassembled frequently. In those situations, using brass heat set inserts gives the fasteners something stronger to bite into.
You can install these inserts by hand, but if you plan on doing a lot of them, a dedicated press station like the one [Chris Chimienti] recently put together will save you a lot of aggravation in the long run. In the video after the break he walks viewers through the design and use of the device, which itself relies on a number of 3D printed parts using the very same inserts it’s designed to install.
To build this tool you’ll need a piece of aluminum extrusion, some smooth rod, a couple springs, and an assortment of fasteners. Nothing that wouldn’t likely be in the parts bin of anyone who’s been tinkering with 3D printers for awhile, though even if you had to buy everything, the Bill of Materials will hardly break the bank. For the base you can use a piece of scrap wood, though [Chris] has opted to make it a storage compartment where he can store the inserts themselves. We really like this approach, but obviously you’ll need to have access to woodworking tools in that case.
Clearly shopping on the top shelf, [Chris] purchased a kit that actually came with a Weller soldering iron and the appropriate tips for the various sized inserts. If you’re like us and just buy the inserts that come in a plastic baggie, you may need to adapt the arm to fit your iron of choice. That said, the idea of having a dedicated iron that you can leave mounted in the press makes a lot of sense to us if you can swing it.
[Joshua Vasquez] wrote up a phenomenal guide to getting started with heat set inserts last year that’s an absolute must-read for anyone interested in the concept. Whether you build a dedicated press or just push them in freehand, his tips and tricks will help insure you get the best result possible.

Soldering irons are a personal tool. Some folks need them on the cool side, and some like it hot. Getting it right takes some practice and experience, but when you find a tip and temp that works, you stick with it. [Riccardo Pittini] landed somewhere in the middle with his open-source soldering station, Soldering RT1. When you start it up, it asks what temperature you want, and it heats up. Easy-peasy. When you are ready to get fancy, you can plug in a second iron, run off a car battery, record preset temperatures, limit your duty-cycle, and open a serial connection.
The controller has an Arduino bootloader on a 32u4 processor, so it looks like a ProMicro to your computer. The system works with the RT series of Weller tips, which have a comprehensive lineup. [Riccardo] also recreated SMD tweezers, and you can find everything at his Tindie store.
Soldering has a way of bringing out opinions from novices to masters. If we could interview our younger selves, we’d have a few nuggets of wisdom for those know-it-alls. If ergonomics are your priority, check out TS100 3D-printed cases, which is an excellent iron, in our opinion.
The TS100 smart soldering iron may have some new competition. Pine — the people best known for Linux-based phones and laptops — though the world needed another smart soldering iron so they announced the Pinecil — Sort of a knock off of the TS100. It looks like a TS100 and uses the same tips. But it does have some important differences.
It used to be a soldering iron was a pretty simple affair. Plug in one end; don’t touch the other end. But, eventually, things got more complicated and you wanted some way to make it hotter or cooler. Then you wanted the exact temperature with a PID controller. However, until recently, you didn’t care how much processing power your soldering iron had. The TS100 changed that. The smart and portable iron was a game-changer and people not only used it for soldering, but also wrote software to make it do other things. One difference is that the device has a RISC-V CPU. Reportedly, it also has better ergonomics and a USB C connector that allows for UART, I2C, SPI, and USB connections. It also has a very friendly price tag of $24.99.
