Building A Lightweight Softbox For Better Photography

Posted on by

If you want to take good photographs, you need good light. Luckily for us, you can get reels and reels of LEDs from China for pennies, power supplies are ubiquitous, and anyone can solder up a few LED strips. The missing piece of the puzzle is a good enclosure for all these LEDs, and a light diffuser.

[Eric Strebel] recently needed a softbox for some product shots, and came up with this very cheap, very good lighting solution. It’s made from aluminum so it should handle the rigors of photography, and it’s absolutely loaded with LEDs to get all that …read more

Guess what’ll be wrapping up in just two weeks? The Midwest RepRap Festival, the largest con for open source 3D printing in the world. MRRF is going down in Goshen, Indiana on March 23rd through March 25th. Tickets are free! If you’re looking for a hotel, I can speak from experience that the Best Western is good and close to the con, and I haven’t heard anything bad about the Holiday Inn Express.

Want to go to a convention with even weirder people? Somehow or another, a press release for Contact In The Desert, the largest UFO conference in the …read more

Racing The Beam On An ATtiny

Posted on by

For the last thirty or so years, the demoscene community has been stretching what is possible on computer systems with carefully crafted assembly and weird graphical tricks. What’s more impressive is hand-crafted assembly code pushing the boundaries of what is possible using a microcontroller. Especially small microcontrollers. In what is probably the most impressive demo we’ve seen use this particular chip, [AtomicZombie] is bouncing boing balls on an ATtiny85. It’s an impressive bit of assembly work, and the video is some of the most impressive stuff we’ve ever seen on a microcontroller this small.

First, the hardware. This is just …read more

Autodesk Introduces Parametric Part Generation

Posted on by

The hardest part of any PCB design is adding parts and components. You shouldn’t use random part libraries, and creating your own part libraries is just a pain. Why have we endured this pain for so long, especially considering that most components follow a standard? Add in the fact that 3D modeling and rendering a board in a mechanical CAD tool is now a thing, making creating your own part libraries even more involved.

To solve this problem, Autodesk has introduced library.io, a tool to parametrically generate component footprints for Eagle and 3D models for Fusion360. Given that most parts …read more

Friday Hack Chat: Everything About The ESP

Posted on by

When the ESP-8266 first arrived, it was a marvel. For two dollars, you could buy a simple module that could serve as a bridge between WiFi networks and microcontroller projects. It understood the Hayes command set, it didn’t use much power, and, as noted before, it only cost two dollars. The idea of cheap and accessible Internet of Things things was right there for the taking.

Then hackers figured out what was actually going on inside the ESP-8266. It was a full-blown microcontroller. There was Lua stuff you could put on it. You could program it with the Arduino IDE …read more

Detoured: Inside MachineHistories

Posted on by

When designers and architects need a fancy centerpiece, a design element, or even some wall sconces, they don’t head over to the machine shop by themselves. They get someone else, who owns some fancy machines, knows how to use those fancy machines, and can create anything out of wood, foam, or metal to do the fabrication for them. Think of these companies as artisan contractors, capable of turning whatever an architect thinks of into a real, tangible object.

One of these such companies is MachineHistories, a joint venture between [Steven Joyner] and [Jason Pilarsky], who work in the medium of …read more

Badgelife: From 1 To 100

Posted on by

Blame it on the falling costs of printed circuit boards, the increased accessibility of hardware design tools, the fact that GCC works on microcontrollers now, whatever the ‘maker movement’ is, or any one of a number of other factors. There’s a hardware demoscene now. Instead of poking bits, writing code, and dividing by zero to create impressive multimedia demonstrations on a computer, there is a small contingent of very creative people who are building their own physical hardware, just for the hell of it. They’re pushing boundaries of what can be done with hardware design, demonstrating manufacturing know-how, and turning …read more

Guess what’s happening next weekend? The SoCal Linux Expo. SCALE is in its 16th year, and is the second greatest convention happening this year at the Pasadena Convention Center. The first, of course, is AlienCon this summer, with a special guest appearance by the guy with the hair on Ancient Aliens. What’s cool at SCALE? Tons of stuff! Tindie and Hackaday will have a booth, you’ll be able to check out the new stuff from System 76, and this is where I first picked up my most cherished possession, a Microsoft (heart) Linux sticker. NEED A TICKET? Cool, use the …read more

Microchip Acquires Microsemi For $8.35B

Posted on by

Microchip has acquired Microsemi for $8.35 Billion dollars. Rumors of this acquisition were floating around earlier this week, but now the deal is done.

This acquisition is the latest in a years-long process of consolidation in the silicon industry. Previously, Broadcom attempted a hostile takeover of Qualcomm for One… Hundred… Billion dollars. Lattice would have been bought if the deal wasn’t shut down for national security concerns. Of course, Microchip bought Atmel in a deal likened to the fall of Constantinople, NXP and Freescale merged, Intel bought Altera, Linear and Analog are one, and On Semiconductor acquired Fairchild.

With the …read more

New Part Day: ATMegas With Programmable Logic

Posted on by

Since Microchip acquired Atmel, the fields of battle have fallen silent. The Crusaders have returned home, or have been driven into the sea. The great microcontroller holy war is over.

As with any acquisition, there is bound to be some crossover between two product lines. Both Atmel’s AVR platform and Microchip’s PICs have their adherents, and now we’re beginning to see some crossover in the weird and wonderful circuitry and design that goes into your favorite microcontroller, whatever that might be. The newest part from Microchip is an ATMega with a feature usually found in PICs. This is a Core …read more
