First soldering irons are often of the Radioshack or Maplin firestarter variety. They’re basically wall power shorted across a nichrome heater or similar with some inline resistance to make it harder to burn down the house. You plug them in, the current flows, and they get hot. Done. If you stick with the hobby for […]
For those that grew up working with through-hole components, surface mount parts can be challenging to deal with. However, there are plenty of techniques out there that are more than accessible to the DIY set. With the right gear, soldering SMD boards is a snap – just get yourself a hot pan of sand (Youtube […]
Solder is the conductive metal glue that one uses to stick components together. If you get the component and the PCB hot enough, and melt a little solder in the joint, it will stay put and conduct reliably. But it’s far from simple. There are many different solder alloys, and even the tip of the […]
Hackaday editors Elliot Williams and Mike Szczys gather round the microphone to spin tales from a week of hacks. All the rage are fax-machine-based malware, a hydrogen fuel cell drone, and bringing color to the monochrome world of the original Super Mario Land. There are at least three really cool LED hacks this week, plus […]
Often it feels as if soldering is deemed to be more of an art form than something that’s underpinned by the cold, hard reality of physics and chemistry. From organic chemistry with rosin, to the material properties of fragile gold bond wires and silicon dies inside IC packages and the effects of thermal stress on […]
What do you do if you have to solder thousands of through-hole parts? The expensive, professional way of doing this is running the boards through a wave soldering machine, or a machine with a fancy CNC solder fountain. The amateur way of soldering thousands of through-hole joints is putting some boards on the workbench and […]
There was a time when a decent temperature controlled soldering iron took the form of the iron itself and a box of electronics, but now it’s just as likely to be a miniaturised affair with the temperature controller built into a slim and lightweight handle. Irons such as the Miniware TS series have become firm […]
[DJ Legion] decided he wanted a reflow oven so he bought a toaster oven and an assortment of parts including a solid state relay, a Teensy, a display, and a thermocouple. What makes this a different project is the amount of video documentation. The four videos below encompass about 50 minutes of information and he’s […]
You can define the word crazy in myriad ways. Some would say using SMD resistors and QFN microcontrollers as structural elements is crazy. Some would say hand soldering QFN is crazy, much less trying to do it on edge rather than in the orientation the footprint is designed for. And of course doing it live […]
