It’s not everyday that we review software around here, but the folks at Adafruit recently put together an iOS app that I figured might be of interest. Their iPad/iPhone compatible application is called “Circuit Playground”, and it includes all sorts of handy electronics reference tools. For the context of this review, it should be noted [...]

Agonize no more over stripping the insulation off of tiny wires like those used in ribbon cables. For years we’ve used razor blades to do this, as the tiniest wires don’t have a slot on our trusty wire strippers. But often we cut all the way though the conductor (or many of the strands) when [...]

[Brad] had an extremely productive January 18th. Considering how many websites went dark to protest SOPA, we can’t blame him. While considering what he could get done if popular Internet time sinks went dark on command, [Brad] thought of the Stop Online Productivity Avoidance box. This build will redirect all traffic to sites like reddit, hacker [...]

[Lindsay] has a wonderful writeup about a new toy in the shop, an ultrasonic transducer. The 28kHz, 70W bolt-clamped Langevin transducer by itself is not much use, you need a power supply, a horn to focus the energy, and a way to tune it. [Lindsay] starts off by showing how to find out the resonant [...]

For most of the past year, [Joel] has been working on converting a manual mill to a CNC mill with the addition of a computer, brackets and stepper motors. He’s put an amazing amount of effort into his project, and the result is awesome and much less expensive than buying and shipping an old Bridgeport mill. [...]

[RandomTask] has posted a nice tutorial on how to use a FTDI serial to usb converter, and a couple analog to digital converters to make a simple software oscilloscope. Using a “Universal Serial to USB converter” and one of many FTDI break out boards, he first reprograms the chip using FTDI’s programming software to put [...]

Here’s something that may be of interest to all the reprappers, vacuum formers, and other plastic fabbers out there: ultrasonic welding of plastics. If you’ve ever wanted to join two pieces of plastic without melting them together with acetone or screwing them together, [circuitguru] is your guy. Ultrasonic welder setups are usually reserved for companies that [...]

We see people driving around the night before trash collection and reclaiming items doomed to the land fill (or on their way to recycling… who knows). We’re beginning to think we need to join those ranks. Case in point is this vintage oscilloscope which [Bob Alexander] plucked from the curb in the nick of time. [...]

If you do a lot of SMD soldering, a reflow oven is the fastest and most efficient way to get all those tiny components attached to your PCB. [Frank Zhao] saw the reflow ovens we featured here over the last few weeks and figured he might as well show off his rig as well. We’re [...]

We love our little Rigol 1052E oscilloscope. It’s seen us through some perplexing problems and loved being upgraded from 50 MHz to 100 MHz. We’ve always been pleased with its role dictating waveforms for us, but we never thought we’d see homebrew apps for our little ‘scope. We’re not exactly sure who [Krater] is, but [...]

Those of us with 3D printers have had two major choices when selecting a material to print with – ABS, a very hard plastic, and PLA, a more brittle plastic with a lower melting point. [Alex] and [Luke] have been experimenting with printing polycarbonate and creating clear crystalline objects on a standard 3D printer. The first foray [...]

Admittedly this post is flirting with flamebait, but we think the concept of using a spring clamp as an iPhone tripod mount has a lot of hacking potential. Hear us out, and if we havn’t made our case you can rant about it in the comments. [Joe] wanted an easy way to mount his iPhone [...]

It looks like Null Space Labs has a new pick and place machine. This immense repair job began when [Charliex] and [Gleep] found a JukiPlacemat 360 pick and place machine. The idea of having their very own pick and place machine proved intoxicating, possibly too much so because the didn’t return the machine when they found out [...]

We’re kind of surprised we haven’t covered this concept before since it only uses techniques that are commonly avaialable for home PCB fabrication. [Ray] made this solder paste stencil out of a sheet of copper using the same etching techniques you would for a circuit board. He designed and printed a resist pattern, with toner [...]

Here’s a neat 4x4x4 LED cube made with an ElecFreaks Flower Protoboard. A few days ago, we posted a neat new prototyping board made specifically for SMD work. Instead of the usual ‘holes-with-circles’ protoboard layout, the ElecFreaks team decided to go with a flower-shaped pad. This makes it especially easy to deal with SMD components when building [...]

Anybody who has a 3D printer always has a ton of useless plastic lying around. Some of that plastic may be from useless baubles, but most of it is in bad prints, short bits of filament, and general scraps. [Luke] found an interesting way to put those ABS scraps to use, and ended up turning [...]

Despite what this module says on the case, it’s certainly not official Saleae Logic Analyzer hardware. [Jack Andrews] picked up this Chinese knockoff on eBay for about $18. When plugged into the computer the Saleae software picks it up as the official hardware. But [Jack] has seen other knockoffs which have a jumper to select [...]

When [Todd Harrison’s] Christmas lights stayed on well past the pre-defined shut off time, he knew there was something wrong with the timer. He took the device into his workshop and spent some time diagnosing and repairing the device, a process he recorded for all to see. After busting the screw-less timer open with a [...]

This one almost got relegated to a links post, but [Ken's] simple PCB vise (PDF) is just so useful we had to give it a standalone feature. It works so well because he made every design feature count. For instance, the groove the holds the PCB (almost impossible to see here but look at the [...]

What makes a project really exceptional? Part of it is a, ‘gee, that’s clever’ angle with a little bit of, ‘that’s actually possible.’ One thing the Hack a Day crew really appreciates is awesome enclosures. Altoids tins will get you far, but to step up to the big leagues you’ve got to bend some aluminum. [...]

What do you do when you’ve got three broken function generators? Build your own, obviously. Since your workshop has already gone through three of these bad boys, you might find yourself repairing your build. Better not use any fancy ICs and go with a transistor only build. When [Miroslav] sent in his ‘guerilla homebrew’ square [...]

With the introduction of the Kinect, obtaining a 3D representation of a room or object became a much easier task than it had been in the past. If you lack the necessary cash for one however, you have to get creative. Both the techniques and technologies behind 3D scanning are somewhat complicated, though certainly still [...]

[HammyDude] was tired of buying replacement batteries for his power tools. He had some Lithium Polymer batteries on hand and decided to take one of his dead drills and swap out the dead power pack. The orange battery pack you see above has a deans connector on it for use with RC vehicles. By opening [...]

When [Adr1an] wrote in to share a link to his PCB etching tutorial he mentioned that he knew we had already covered a ton of these guides. He’s absolutely right, not only have we featured a great number of them, but we also wrote our own quite a while ago. But that doesn’t mean we [...]

[Eberhard] wanted his own reflow oven but didn’t really want to mess around with the internals that control the heating element. He put his microcontroller programming experience to work and came up with an add-on module that controls the oven by switching the mains power. The image above shows a board in the midst of the [...]

[Koogar] came up with a useful tool for checking the measurements of your layouts in Eagle CAD. He calls it the Gridrunner; a custom part that adds a 200mm ruler to your design. Tick marks are in 1/10th of a millimeter increments for great accuracy when used with the zoom feature of Eagle. Once you’ve [...]

[Raphaël Assénat] needed anti-static bags for some boards he is selling. He had a lot of leftovers on hand (presumably from the components he ordered to assemble these boards) and wanted to reuse them. Instead of buying a heat sealer he built his own to cut them down to size. His build starts with a [...]

[Karl] wrote in to tell us about a software package called EagleUp that will import your Eagle CAD PCB designs into Google SketchUp. It bridges the gap between the two using the open source image processing software ImageMagick. As you can see above, you’ll end up with a beautifully rendered 3D model of your hardware. [...]

[Sebastian] needed a small solder oven so he bought himself a small toaster oven (Spanish, Google Translate). It’s not the kind of thing we’d make our breakfast in now, but for soldering it’s a very nice oven. After a little bit of research on Google, [Sebastian] discovered that the best technique when dealing with reflow [...]
