Advances In Flat-Pack PCBs

Posted on by

Right now, we’ve got artistic PCBs, we’ve got #badgelife, and we have reverse-mounted LEDs that shine through the fiberglass substrate. All of this is great for PCBs that are functional works of art. Artists, though, need to keep pushing boundaries and the next step is obviously a PCB that doesn’t look like it has any components at all. We’re not quite there yet, but [Stephan] sent in a project that’s the closest we’ve seen yet. It’s a PCB where all the components are contained within the board itself. A 2D PCB, if you will.

[Stephen]’s project is somewhat simple as …read more

Amazon Creates Distributed Satellite Ground Stations

Posted on by

Here’s an interesting thought: it’s possible to build a cubesat for perhaps ten thousand dollars, and hitch a ride on a launch for free thanks to a NASA outreach program. Tracking that satellite along its entire orbit would require dozens or hundreds of ground stations, all equipped with antennas and a connection to the Internet. Getting your data down from a cubesat actually costs more than building a satellite.

This is the observation someone at Amazon must have made. They’ve developed the AWS Ground Station, a system designed to downlink data from cubesats and other satellites across an entire orbit. …read more

Bill Gross On Why Your Startup Will Succeed

Posted on by

Bill Gross is one of the great heros when it comes to technology incubators. Twenty years ago, he founded Idealab, a business whose business plan is to create more businesses. This started out with just a handful of companies in 1996, and has since gone on to found 150 companies, that have collectively raised three and a half billion dollars. Out of these companies, more than half have either gone through successful IPOs and acquisitions, or are currently operating. That investment has generated a 13.5x return, and created more than 10,000 jobs.

Obviously, when you want to talk about what …read more

A Sub-$1000, Non-X86 Motherboard

Posted on by

If you’re building a computer, your options are nearly limitless. You can get a motherboard with red LEDs, with blue LEDs, green LEDs, or if you’re feeling spendy, RGB LEDs. You can get custom-milled heat spreaders in any shape you want, as long as it’s angular and screams ‘gamer’. If you want a motherboard that doesn’t use x86 — either AMD or Intel — you’re kind of out of luck. Either it doesn’t exist, or it’s going to cost a small fortune.

Raptor Engineering have just released a motherboard that isn’t x86 and doesn’t cost as much as a …read more

Applied Science Rolls An Electroluminescent Controller

Posted on by

After LEDs and TFTs and OLEDs and liquid crystals, there’s another display technology that doesn’t get a lot of attention. Electroluminescent displays have been around for ages, and there still aren’t a whole lot of applications for them. That might change soon, because Applied Science a.k.a. [Ben Krasnow] figured out an easy way to build EL displays on anything, and created a simple circuit that’s capable of driving video on a remarkable blue phosphor EL display.

For this build, [Ben] is using a specialty product from Lumilor consisting of a copper-ish conductive base layer, a clear dielectric, the ‘lumicolor’ phosphor, …read more

Hackaday Links: November 25, 2018

Posted on by

Bad Obsession Motorsport have been stuffing the engine and suspension from a 4WD Celica into an old Mini since forever. It is a wonderful homage to Police Squad and some of the best machining and fabrication you’ll see on YouTube. The latest episode tackled the electrical system and how to drive an alternator in an extremely cramped engine bay. The solution was a strange flex-shaft confabulation, and now the Bad Obsession Motorsport guys have a video on how they attached an alternator to a car where no alternator should go. It’s forty minutes of machining, go watch it.

Last Friday …read more

Adding Vector Art To Your Eagle Boards

Posted on by

Badgelife and the rise of artistic PCBs are pushing the envelope of what can be done with printed circuit boards. And if you’re doing PCB art, you really want to do it with vectors. This is a surprisingly hard problem, because very few software tools can actually do DXFs and SVGs properly. Never fear, because [TallDarknWeirdo] has the solution for you. It’s in Eagle, and it uses Illustrator and Inkscape, but then again this is a hard problem.

The demonstration article for this example is just a Christmas tree. It’s somewhat topical green soldermask is standard, FR4 looks like wood, …read more

The Best Laptop Gets Even Better

Posted on by

The ThinkPad is the greatest laptop ever created. It doesn’t come in rose gold, it comes in black. It doesn’t have a weird screen instead of an escape key. For less than half the price of a MacBook, you can have a capable laptop that will somehow fit three drives inside. It’s madness, but it’s still not the perfect tool for hacking. To get there, you’re going to need to load that thing up with an independent Linux system, and maybe a solderless breadboard. That’s what [ollie] is doing with his ThinkPad, and the results are the perfect addition to …read more

LED-ifying A Guitar, Part Two

Posted on by

An electric guitar is all about stage presence. Need to be cooler than a single guitar? No problem — there are double neck guitars. Need to be cooler than that? No problem, the guy from Cheap Trick has a five-neck guitar. Need to be cooler than that? Robbie Robertson played a guitar with an extra mandolin neck on The Last Waltz. Where do you go from there? Obviously, the solution is putting a TV in your guitar with a boatload of individually addressable LEDs in a guitar. That’s what [Englandsaurus] is doing, and the build thread is now getting into …read more

This Bitcoin Price Tracking Traffic Light Isn’t Just A Red LED

Posted on by

Quick, what’s the price of Bitcoin? Is it lower today than yesterday? Are you overdrafting your Lamborghini account? What if you had an easy way to tell at a glance how much you could have made if you sold in December of last year? That’s what this Bitcoin price tracking traffic light is all about, and it’s a great use of existing electronics.

The hardware for this build is a traffic light table lamp available on Amazon for twenty bucks. Inside this traffic light, you get a PCB with three LEDs and a small microcontroller to control the LEDs. The …read more
