Not Your Typical ATX Bench PSU

We know what you’re thinking — yet another scrap PC power supply turned into a bench PSU. But look a little closer and you’ll see a nicely designed linear bench supply that just fits inside a gutted ATX case.

A lot of the items on [Medzik]’s BOM for this build are straight from the scrap bin. The aforementioned ATX supply case is one, as is the power transformer donated by a friend. Modules such as the 30V/2A regulator, the digital volt/ammeter, and a thermostat module to control the fan at higher power settings were all sourced via the usual suspects. …read more

Global Thermonuclear War: Tweeted

[Andreas Spiess] did a video earlier this year about fallout shelters. So it makes sense now he’s interested in having a Geiger counter connected to the network. He married a prefabricated counter with an ESP32. If it were just that simple, it wouldn’t be very remarkable, but [Andreas] also reverse-engineered the schematic for the counter and discusses the theory of operation, too. You can see the full video, below.

We often think we don’t need a network-connected soldering iron or toaster. However, if you have a radiological event, getting a cell phone alert might actually be useful. Of course, if …read more

Fighting Machine Tool Chatter with a 555 Timer

Vibration is a fact of life in almost every machining operation. Whether you’re milling, drilling, turning, or grinding, vibration can result in chatter that can ruin a part. Fighting chatter has generally been a matter of adding more mass to the machine, but if you’re clever about things, chatter reduction can be accomplished electronically, too. (YouTube, embedded below.)

When you know a little something about resonance, machine vibration and chatter start to make sense. [AvE] spends quite a bit of time explaining and demonstrating resonance in the video — fair warning about his usual salty shop language. His goal with …read more

A Screwdriver for the Lazy

The TS100 soldering iron is a sleek handheld device with a tiny display. Now the same people behind it have introduced a motion-controlled screwdriver, the ES120. While we are fans of large electric screwdrivers for working on large projects, we aren’t sure we need a $90 screwdriver for little fasteners. However, if you watch the video review from [Marco], you’ll see it has an interesting user interface that might be useful in other projects. [Marco] is also a bit of a cut up, so you’ll get to see how well the little tool can froth milk, provide transportation, or change …read more

Laser-Cut Modular Toolbox

[ystoelen] created this modular wooden toolbox out of laser-cut 5mm plywood secured with leather hinges bolted into place. The leather strips secure the various tool boards with grommets connecting to plastic plugs. The toolboards use cross-shaped holes with laser-cut plugs and strips of elastic securing the tools, allowing each board to be uniquely configured depending on what tool is being stored there. There is a larger, “main” board, onto which smaller boards can be placed depending on what tools you’ll need.

While this is a clever approach to tool transport, we have some concerns about this project. Usually the problem …read more

Smooth and Steady Cuts with an Improvised Power Feeder

Some woodworking operations require stock to be fed at a smooth, steady rate, for which purpose a power feeder is usually employed. They’re expensive bits of gear, though, and their cost can usually be borne only by high-output production shops. But when you need one, you need one, and hacking a power feeder from a drill and a skate wheel is a viable option.

It should come as no surprise that this woodshop hack comes to us from [Matthias Wandel], who never seems to let a woodworking challenge pass him by. His first two versions of expedient power feeders were …read more

Field Expedient Quenches Your Thirst for a Soldering Station

In the category of first world problems, it seems that these days no one is happy with just a plain old soldering iron. Today, everyone wants a station with bells, whistles, and features. If all you have is the iron, take heart. Grab a soda, drink it, and then duplicate [Kalvin178’s] makeshift solder station.

The idea is simple: cut or tear a soda can and press in the sides to make a V-shaped holder for the iron. A smaller part of the can might hold a wet paper towel, a sponge, or some copper scrubbing pads to clean your tip. …read more

A Battery-Tab Welder with Real Control Issues

Spot welding should easier than it looks. After all, it’s just a lot of current in a short time through a small space. But it’s the control that can make the difference between consistently high-quality welds and poor performance, or maybe even a fire.

Control is where [WeAreTheWatt]’s next-level battery tab spot welder shines. The fact that there’s not a microwave oven transformer to be seen is a benefit to anyone sheepish about the usual mains-powered spot welders we usually see, even those designed with safety in mind. [WeAreTheWatt] chose to power his spot welder from a high-capacity RC battery …read more

Cutting Stone with a Diamond Bit Built from Plumbing parts

Everyone’s favorite Canadian is at it again. This time, [AVE] needed to cut a large hole in a stone countertop. They making coring bits for this, but a bit this size would cost upwards of $400. Not a problem. [AvE] broke out the tools and built his own stone cutting bit.

Everything starts with a 6″ plastic pipe cap. [AvE] center drilled the cap, then threaded it. A turned down bolt makes a great arbor for this new tool. The edge of the cap was then slotted. [AvE] used a clapped out Bridgeport milling machine, but you could do the …read more

Think You Know Everything About Soldering?

[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
