What to do with Your Brand New Ultrasonic Transducer

Posted on by

We wager you haven’t you heard the latest from ultrasonics. Sorry. [Lindsay Wilson] is a Hackaday reader who wants to share his knowledge of transducer tuning to make tools. The bare unit he uses to demonstrate might attach to the bottom of an ultrasonic cleaner tank, which have a different construction than the ones used for distance sensing. The first demonstration shows the technique for finding a transducer’s resonant frequency and this technique is used throughout the video. On the YouTube page, his demonstrations are indexed by title and time for convenience.

For us, the most exciting part is when …read more

A Pin Pusher To Make Life Easier

Posted on by

Picture the scene: you’ve whipped up an amazing new gadget, your crowdfunding campaign has gone well, and you’ve got a couple hundred orders to fill. Having not quite hit the big time, you’re preparing to tackle the production largely yourself. Parts begin to flood in, and you’ve got tube after tube of ICs ready to populate your shiny new PCBs? After the third time, you’re sick and tired of fighting with those irksome little pins. Enter [Stuart] with the answer.

It’s a simple tool, attractively presented. Two pieces of laser cut acrylic are assembled in a perpendicular fashion, creating a …read more

Tachometer Uses Light, Arduinos

Posted on by

To measure how fast something spins, most of us will reach for a tachometer without thinking much about how it works. Tachometers are often found in cars to measure engine RPM, but handheld units can be used for measuring the speed of rotation for other things as well. While some have mechanical shafts that must make physical contact with whatever you’re trying to measure, [electronoobs] has created a contactless tachometer that uses infrared light to take RPM measurements instead.

The tool uses an infrared emitter/detector pair along with an op amp to sense revolution speed. The signal from the IR …read more

[SANS ISC] Investigating Microsoft BITS Activity

Posted on by

I published the following diary on isc.sans.org: “Investigating Microsoft BITS Activity“: Microsoft BITS (“Background Intelligent Transfer Service”) is a tool present[1] in all modern Microsoft Windows operating systems. As the name says, you can see it as a “curl” or “wget” tool for Windows. It helps to transfer files between

Digital Kiln

Posted on by

A kiln or foundry is too often seen as a piece of equipment which is only available if a hackspace is lucky enough to have one or individuals are dedicated enough to drop the cash for one of their own. [The Thought Emporium] thought that way until he sourced materials to make his own kiln which can also be seen after the break. It costs half the price of a commercial model not including a failed—and exploded—paint can version.

As described in the video, these furnaces are tools capable of more than just pottery and soft metal baubles. Sure, a …read more

Automatic Extraction of Data from Excel Sheet

Posted on by

Excel sheets are very common files in corporate environments. It’s definitively not a security tool but it’s not rare to find useful information stored in such files. When these data must be processed for threat hunting or to collect IOC’s, it is mandatory to automate, as much as possible, the processing

Rescuing An Antique Saw Set

Posted on by

Who doesn’t like old tools? Even if they aren’t practical to use for production, plenty of old tools still have a life to offer the hobbyist or home worker.  Some tools might seem a bit too far gone – due to age, rust, or practicality, to use. That’s where [Hand Tool Rescue] comes in. [HTR] finds rusty, dirty old tools, and brings them back to life. Sometimes they’re practical tools, other times, they’re a bit out there. In a recent video, he restored a BeMaCo automatic saw set from the 1940’s. Saw sets are tools which bend each tooth of …read more

Cutting Stone with a Diamond Bit Built from Plumbing parts

Posted on by

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

Modding A Powdercoating Gun For Performance

Posted on by

In life, tools come in two varieties – good tools, and cheap tools. This is where the hacker steps in, to transform a cheap tool into more than the sum of its parts. [Josh] had problems with his Eastwood powdercoating gun. [Josh] decided to fix things with a couple of tasteful mods.

The problem with the gun was related to the delivery of powder to the workpiece. The stream was either too weak to coat properly, or too heavy, delivering a thick stream of powder. [Josh] surmised that with better airflow into the powder reservoir, the gun would deliver a …read more
