The TS100 is a popular entry into the new breed of small temperature-controlled soldering irons that, at least for some of us, have started to replace the bulky soldering stations of old. Unfortunately, one downside of this particular model is the need to plug it into a fairly ungainly laptop-style power supply, which certainly hinders its otherwise portable nature. But [Dennis Schneider] has come up with a very slick solution to that problem by adding a USB-PD module to his TS100.
The idea here is very simple: just remove the original DC barrel connector, and in its place install a USB-PD trigger module. In practice it took more than a little fiddling, cutting, persuasion, and creative soldering (ironically, with a soldering station), but the end result does look quite professional.
It helps that the USB-PD module [Dennis] used was almost the exact same width as the TS100 PCB, meaning that the modified iron could go back into its original case. Though as we saw not so long ago, there’s a growing community of 3D printed replacement cases should you select a trigger module that doesn’t so neatly fit the footprint of the original board. Or if you didn’t want to modify the iron at all, you could always just make an external adapter.
Those that have some experience with these irons might be wondering what the point of modifying the TS100 to take USB-C is when we already have the TS80. As it turns out, while the TS80 is using a USB-C connector it doesn’t actually use USB-PD, so its not taking advantage of the enhanced power delivery capabilities. We know, it’s all kind of confusing.
About a year back, [BogdanTheGeek] found himself in need of a new case for this TS100 soldering iron. Unfortunately, while the product is often billed as being open source friendly (at least in the firmware sense), he was surprised to discover that he couldn’t find the detailed dimensions required to 3D print his own replacement case. So he took it upon himself to document the case design and try to kick off a community around custom enclosures for the popular portable iron.
The main goals while designing the replacement case was to make it printable without support, and usable without additional hardware. He also wanted it to be stronger than the original version, and feature a somewhat blockier design that he personally finds more comfortable. The case was designed with PLA in mind, and he says he’s had no problems with the lower-temperature plastic. But if you’re still concerned about the heat, PETG would be an ideal material to print yours in.
It took him many attempts to get the design to where it is today, and still, there are improvements he’d like to make. For one, there’s no protective cover over the iron’s OLED screen. He’d also like to make the switch from SolidWorks over to FreeCAD so the project is a bit more accessible, and says he’d appreciate anyone who wants to chip in. We’re excited to see what develops once the hacking world realizes that there are accurate open source CAD files for the TS100 floating around out there.
Our very own [Jenny List] put the TS100 through its paces not so long ago, and found a decidedly solid little tool. While it won’t replace your high-end soldering station, it’s very convenient for quick repairs and simple tasks, especially if you find yourself away from the workbench proper.
A device that even DIY enthusiasts don’t usually think to DIY is the humble soldering iron. Yet, that’s exactly what one Hackaday.io user did by building a USB-powered soldering pen with better performance than a $5 Chinese soldering pen.
The project draws inspiration from another Weller RT tip-based soldering pen by [vlk], although this project has a simpler display than an OLED. Slovakia-based maker [bobricius] was inspired by the DiXi ATSAMD11C14-based development board. The project uses the same 32-bit ATMEL ARM microcontroller with a USB bootloader, which makes updating the firmware a lot easier.
Two buttons control the heat (+/-) and the jack for the Weller RT soldering tip controls the power out with PWM. For the display, 20 Charlieplexed 3014 LEDs are used to show the temperature from 0-399. The last missing LED is left out since 5 GPIO pins can only drive 20 LEDs.
Assuming that the main heating controls stay the same as [vlk]’s project, the pen uses a current sensor and heating controller for PID control of a heating module, which connects to the SMT connector for the Weller RT soldering iron tip. The temperature sensor uses a an op-amp for amplification of the signal from a type K thermocouple.
While there aren’t currently GERBER files for the PCB yet, the project is based on the open-source OLED display soldering pen project by [vlk], whose schematic for the device is published.

If you have a portable gadget, the chances are you’ve probably used power banks before. What few could have predicted when these portable battery packs first started cropping up is that they would one day be used to power soldering irons. Dissatisfied with the options currently available on the market, [Franci] writes in with his own power bank specifically designed for use with his TS80 portable soldering iron.
The electronics side of this build is simple and easy to replicate, with 4 18650 Li-ion cells standard to most high-capacity power banks and an off-the-shelf Fast Charge module serving as the brains of the operation. The beauty of this project however lies in the design of the actual case, completely custom-made from scratch to be 3d printed.
Unlike most power banks, where the outputs stick out to the side and leave the connectors prone to being bumped and damaged, [Franci] engineered his case so the ports are stacked on top and facing inwards. That way, USB plugs are contained within the footprint of the power bank’s body, and therefore protected from bending or snapping off in the socket. He also gracefully provides all instructions needed to make your own, including a wiring guide and a reminder about safety when dealing with battery packs.
If you’re unfamiliar with the TS80 soldering iron, we’ve featured the younger sibling of the TS100 in a previous post. And if you think this power bank is too simple for you, don’t worry, we’ve got you covered.
You’ve surely seen the TS-100 soldering iron. It has an OLED display, an ARM processor, and will run with an external battery pack. They are not too pricey, but at $80 or so they aren’t exactly an impulse buy, either. [Drone Camps RC] used one in the field and decided to try a Hakko FX-901 instead. He did a video review that you can see below.
The FX-901 is about half the price of a TS-100. Granted, it doesn’t have a fancy display and you can’t hack it to play Tetris. However, it does take batteries (including rechargeable) without an external pack. The manufacturer claims up to two hours of use and that it will melt solder in 40 seconds. From the video, the iron actually melted solder in under 30 seconds. The two hours, by the way, is with rechargeables. Alkaline AA batteries should give about 70 minutes of operation.

When it’s time to get started on a project and put our irons in the fire, we usually reach for a nice Weller or Hakko soldering iron. Unfortunately, that isn’t possible when we’re soldering something away from a wall outlet. Portable soldering irons usually range from slightly to completely terrible, and [Adam] thought he could do better. He put together an Instructable for a portable battery-powered soldering iron that’s extremely easy to build.
[Adam]’s project mounts a standard Radio Shack soldering iron tip in an E-10 flashlight bulb socket. Power is provided by 6 Volts of AA batteries, with a small switch added for the obvious safety concerns. Although [Adam] could have added a small project box, he chose to build his entire project around a piece of wood. This is an excellent choice in our humble opinion; wood doesn’t melt, has very low thermal conductivity, and anyone using this iron should be smart enough to turn it off if the handle starts smoking.
While this isn’t the best possible portable soldering iron (we’re partial to the disposable-lighter-fueled torches with a soldering iron attachment), it’s much better than the ColdHeat soldering iron that received consistently bad reviews.
Edit: [Adam] updated his build to be a little safer after this story was posted. We changed the original title pic to reflect this; here’s the old one.
