Did you ever stop to think how unlikely the discovery of soldering is? It’s hard to imagine what sequence of events led to it; after all, metals heated to just the right temperature while applying an alloy of lead and tin in the right proportions in the presence of a proper fluxing agent doesn’t seem like something that would happen by accident.
Luckily, [Chris] at Clickspring is currently in the business of recreating the tools and technologies that would have been used in ancient times, and he’s made a wonderful video on precision soft soldering the old-fashioned way. The video …read more
We’ll admit it. Most of us have been soldering since we were kids and we don’t think of it as a particularly dangerous activity. Just keep the hot and cold end of the iron straight and remember not to flick solder off the tip on your leg and you are fine. We sometimes roll our eyes a bit at the people with the soldering fume extractors unless you are soldering 8 hours a day, although we’ve occasionally used a small fan nearby just to get some circulation. [Tanner Tech’s] video on soldering fumes might make us rethink that, though (see …read more
While complex devices assembled from 3D printed components are certainly impressive, it’s the simple prints that have always held the most appeal to me personally. Being able to pick an object up off the bed of your printer and immediately put it to use with little to no additional work is about as close as we can get to Star Trek style replicators. It’s a great demonstration to show off the utility of your 3D printer, but more importantly, having immediate access to some of these tools and gadgets might get you out of a jam one day.
With that …read more
While Apple products have their upsides, the major downside with them is their closed environment. Most of the products are difficult to upgrade, to say the least, and this is especially true with the iPhone. While some Android devices still have removable storage and replaceable batteries, this has never been an option for any of Apple’s phones. But that doesn’t mean that upgrading the memory inside the phone is completely impossible.
[Scotty] from [Strange Parts] is no stranger to the iPhone, and had heard that there are some shops that can remove the storage chip in the iPhone and replace …read more
As an electrical engineering student, [Brandon Rice] had the full suite of electronics tools you’d expect. Cramming them all into a dorm room was doable — but cramped — a labour to square everything away from his desk’s top when he had to work on something else. To make it easier on himself, he built himself a portable electronics workstation inside the dimensions of a briefcase.
Built from scratch, the workstation includes a list of features that should have you salivating by the end. Instead of messing with a bunch of cables, on-board power is supplied by a dismantled 24V, …read more
Everyone needs a helping hand in the shop once in a while, and most of us have gone the traditional route and bought one of those little doohickies with the cast iron base and adjustable arms terminated in alligator clips. They’re cheap, they’re readily available, and they’re “Meh,” at best.
In the quest for better hands, [Jeremy S. Cook] came up with this custom design for a benchtop aid, and we’re pretty impressed. There are commercial designs out there that use the same flexible coolant hoses, called Loc-Line, which are often seen spewing coolant on metalworking machines like mills and …read more
As with the age-old panic after realizing you have left an oven on, a candle lit, and so on, a soldering tool left on is a potentially serious hazard. Hackaday.io user [Nick Sayer] had gotten used to his Hakko soldering iron’s auto shut-off and missed that feature on his de-soldering gun of the same make. So, what was he to do but nip that problem in the bud?
Instead of modding the tool itself, he built an AC plug that will shut itself off after a half hour. Inside a metal project box — grounded, of course — an ATtiny85 …read more
Usually, repairing a device entails replacing a defective IC with a new one. But if you’ve got young eyes and haven’t had caffeine in a week, you can also repair a defective chip package rather than replace it.
There’s no description of the incident that resulted in the pins of the QFP chip being ablated, but it looks like a physical insult like a tool dropped on the pins. [rasminoj]’s repair consisted of carefully grinding away the epoxy cap to expose the internal traces leading away from the die and soldering a flexible cable with the same pitch between the …read more
You could say that it is the essence of a site like this one, that the kind of people who form our readership are also the kind of people who examine the specs of the devices in front of them to reveal hidden features. Such was the case with [Ryan], who noticed that the eMMC controller on his 96Boards HiKey development board supports both HS200 data transfer speeds and 1.8v signaling, both of which it wasn’t using.
In unlocking the extra performance, he takes readers through a primer on the device tree, and is happy to report that his transfer …read more
[Joshua] has frequent discussions about his soldering techniques with viewers of his YouTube channel. He finally decided to interview [Randy Rubinstein] who is the president of SRA Soldering. In nearly an hour, they talk about everything from solder alloys to proper temperature. They also talk about lead exposure, flux cleaning, and lead-free solder.
They also talk about strategies for rework with lead-free and using special solder for removing SMD components. Honestly, although the first frame of the video says “your solder sucks,” we didn’t really find any earth-shattering revelations about something everyone’s doing wrong. We did, however, find a lot …read more
