Here at the Hackaday we’ve been enjoying a peculiar side effect of the single-port USB-C world; the increasing availability of programmable DC power supplies in the form of ubiquitous laptop charging bricks. Once the sole domain of barrel jacks or strange rectangular plugs (we’re looking at you Lenovo) it’s become quite common to provide charging via the lingua franca of USB-C Power Delivery. But harnessing those delectable 100W power supplies is all to often the domain of the custom PCBA and firmware hack. What of the power-hungry hacker who wants to integrate Power Delivery in her project? For that we turn to an excellent video by [Brian Lough] describing four common controller ICs and why you might choose one for your next project.
[Brian] starts off with a sorely-needed explainer of what the heck Power Delivery is; a topic with an unfortunate amount of depth. But the main goal of the video is to dive into the inscrutable hoard of “USB C trigger boards.” Typically these take USB on one side and provide a terminal block on the other, possibly with a button or LED as user interface to select voltage and current. We’ve seen these before as laptop barrel jack replacements and TS100 power supplies but it’s hard to tell which of the seemingly-identical selection is most suitable for a project.
The main body of the video is [Brian’s] detailed walkthrough of four types of trigger boards, based on the IP2721, FUSB302, STUSB4500, and Cypress EZ-PD BCR. For each he describes the behaviors of it’s particular IC and how to configure it. His focus is on building a board to power a TS100 (which parallels his TS100 Flex-C-Friend) but the content is generally applicable. Of course we also appreciate his overview of the products on Tindie for each described module.
As we’ve said many times in the past, the creation of custom cases and enclosures is one of the best and most obvious applications for desktop 3D printing. When armed with even an entry-level printer, your projects will never again have to suffer through the indignity of getting hot glued into a nondescript plastic box. But if you’re printing with basic PLA, you need to be careful that nothing gets too hot inside.
As [Oleg] explains on the Thingiverse page for the case, he actually blended a few existing projects together to arrive at the final design. Specifically, the idea of using the 608 bearing came from a printable TS100 stand originally designed in 2017 by [MightyNozzle]. Released under Creative Commons, [Oleg] was able to mash the bearing stand together with elements from several other printable TS100 cases to come up with his unique combined solution.
By now, I must have had my Miniware TS100 soldering iron for nearly three years. It redefined what could be expected from the decent end of the budget soldering iron spectrum when it came on the market, and it’s still the one to beat even after those years. Small, lightweight, powerful, and hackable, it has even spawned direct imitations.
If the TS100 has a fault, it comes not from the iron itself but from its cable. A high-grade iron will have an extra-flexible PVC or silicone cable, but the TS100 does not have a cable of its own. Instead it relies on whatever cable comes on its power supply, which is frequently a laptop unit built with portable computing rather than soldering in mind. So to use it is to be constantly battling against its noticable lack of flexibility, a minor worry but one that I find irksome. I determined to find a solution, making a DC extension cable more flexible than that on my power supply. Continue reading “The Simplest TS100 Upgrade Leads Down A Cable Testing Rabbit Hole”→
Frequent converter-of-tools-to-USB-C [Jan Henrik] is at it again, this time with a board to facilitate using USB Power Delivery to fuel JBC soldering iron handles. Last time we saw [Jan] work his USB-C magic was with the Otter-Iron, which brought Power Delivery to the trusty TS100 with a purpose built replacement PCBA. This time he’s taking a different approach by replacing the “station” of a conventional soldering station completely with one tiny board and one giant capacitor.
If you’ve been exposed to the “AC fire starter” grade of soldering iron the name JBC might be unfamiliar. They make tools most commonly found with Metcal’s and high end HAKKOs and Wellers on the benches of rework technicians and factory floors. Like any tool in this class each soldering station comes apart and each constituent piece (tips, handles, base stations, stands, etc) are available separately from the manufacturer and on the used market at often reasonable prices, which is where [Jan Henrik] comes in.
The Otter-Iron PRO is a diminutive PCBA which accepts a USB-C cable on one side and the connector from a standard JBC T245-A handle on the other. JBC uses a fairly typical thermistor embedded in the very end of the iron tip, which the Otter-Iron PRO senses to provide closed loop temperature control. [Jan Henrik] says it can reach its temperature setpoint from a cold start in 5 seconds, which roughly matches the performance of an original JBC base station! We’re especially excited because this doesn’t require any modification to the handle or station itself, making it a great option for JBC users with a need for mobility.
Want to make an Otter-Iron PRO of your own? Sources are at the link at the top. It sounds like v3 of the design is coming soon, which will include its own elegant PCB case. Check out the CAD render after the break. Still wondering how all this USB-PD stuff works? Check out [Jason Cerudolo’s] excellent walkthrough we wrote up last year.
When the Miniware TS100 first emerged from China nearly three years ago, it redefined what we could expect from a soldering iron at an affordable price. The lightweight DC-powered temperature controlled iron brought usable power and advanced features in a diminutive package that was easy in the hand, a combination only previously found in much more expensive soldering stations. All this plus its hackability and accessible hardware made it an immediate hit within our community, and many of us have adopted it as our iron of choice.
A surprise has been that it has attracted no serious competitors of a similar type, with the only iron mentioned in the same breath as the TS100 being Miniware’s own USB-C powered TS80. Perhaps that is about to change though, as before Christmas I noticed a new Chinese iron with a very similar outline to the TS100. Has the favourite finally generated a knock-off product? I bought one to find out. Continue reading “Review: SanErYiGo SH72 Soldering Iron”→
By now most readers will be familiar with the Miniware TS100 and TS80 soldering irons, compact and lightweight temperature controlled soldering tools that have set a new standard at the lower-priced end of the decent soldering iron market. We know they have an STM32 processor, a USB interface, and an OLED display, and that there have been a variety of alternative firmwares produced for them.
Take a close look at the TS80, and you’ll find the element connector is rather familiar. It’s a 3.5 mm jack plug, something we’re more used to as an audio connector. Surely audio from a soldering iron would be crazy? Not if you are [Joric], who has created a music player firmware for the little USB-C iron. It’s hardly a tour de force of musical entertainment and it won’t pull away the audiophiles from their reference DACs, but it does at least produce a recognisable We Wish You A Merry Christmas as you’ll see from the video below the break.
Since the TS100 arrived a couple of years ago we’ve seen a variety of inventive firmware for it. You may remember [Joric]’s previous triumph of a Tetris game for the iron, but our favourite is probably the TS100 oscilloscope.
[Jan] didn’t want to modify the original hardware or hack in an adapter. Instead, he struck out on his own, developing an entire replacement PCB for the TS-100 iron. The firmware is rough and ready, and minimal work has been done on the GUI and temperature regulation. However, reports are that functionality is good, and [Jan]’s demonstration shows it handling a proper desoldering task with ease.
Files are on Github for those that wish to spin their own. The PCB is designed to snap neatly inside the original case for a nice fit and finish. Power is plentiful too, as the hardware supports USB Power Delivery 2.0, which is capable of running at up to 100W. On the other hand, the stock TS-80 iron, which natively supports USB-C, only works with Quick Charge 3.0, and thus is limited to a comparatively meager 36W.
