Arduino enthusiasts looking for a project to keep them busy this weekend maybe interested in a new project featured on the official Arduino blog for a handy cable tester. Equipped with a touchscreen the Cable Tracer builds on a previous project that is now 70% smaller than its predecessor and features a custom shield and snap together parts to […]

A lot of phrases surrounding phones don’t make sense anymore. With a modern cellphone, you don’t really “hang up” and there’s certainly no “dial” to be had. However, with [jakeofalltrades’] project, you can read an old-fashioned phone dial using an Arduino. The idea behind a phone dial is actually pretty simple. When you pull the dial back

Don’t blame us for the title. [CCrome] admits it may well be the cheapest and worst IR camera available. The concept is surprisingly simple. Mount a cheap Harbor Freight non-contact thermometer on a 3D printer carriage and use it to scan the target. The design files are available on GitHub. There is, of course, an Arduino to grab
WORLD’S CHEAPEST AND POSSIBLY WORST IR CAMERA Continue Reading
The official Arduino team have introduced a new development board to their range this week in the form of the Portenta H7 Lite Connected which is now available to purchase priced at €82. The Portenta H7 Lite Connected is designed to provide the computational power of the Portenta H7 for AI applications and low-latency control solutions. The small yet

For those of us old enough to remember the VCR (and the difficulty of programming one), the ubiquitous vacuum fluorescent display, or VFD, is burned into our memories, mostly because of their brightness and contrast when compared to the superficially-similar LCD. These displays are incredibly common even apart from VCRs, though, and it’s easy to

When you are responsible for maintaining devices at a client’s location, software tools like remote desktop and SSH are great, but sometimes they are not enough. For some problems, you need to get eyes and hands on the device to figure out what’s going on and fix the problem. This is a challenge [Will Donaldson]

Got a couple of old DVD-RW drives lying around, just collecting dust? Of course you do. If not, you likely know where to find a pair so you can build this totally adorable and fully dangerous laser engraver for your desk. Check out the complete build video after the break. [Smart Tronix] doesn’t just tell you to

Well, here it is: a shoe-in for the new world’s largest NERF gun. (Video, embedded below.) The Guinness people haven’t shown up yet to award [Michael Pick], but at 12.5 feet, this baby is over twice as long as the current record holder, which belongs to former NASA mechanical engineer Mark Rober and his now-puny six-foot

In Banksy’s book, Wall and Piece, there is a very interesting quote; “Imagine a city where graffiti wasn’t illegal, a city where everybody could draw whatever they liked…”. This sounds like it would be a very exciting city to live in, except for those of us who do not have an artistic bone in their body.

Everyone loves watching movies, that is, so long as you can hear what the characters on screen are saying. [GreatScott] found this second part difficult while watching through BladeRunner 2049, so he designed an automatic volume adjuster to assist. At a high level, the solution is fairly straightforward; when there is loud music playing in a
IS YOUR MOVIE TOO LOUD? CAN’T HEAR THE DIALOGUE? THIS CIRCUIT CAN HELP. Continue Reading
