Help Keep The Bombe At Bletchley

Fans of vintage codebreaking machinery might be interested to hear that the only working reconstruction of a Turing-Welchman Bombe is likely to soon be on the move. The electromechanical device, a replica of those used on the Second World War Enigma codes, is housed at Bletchley Park, the former codebreaking center established before the outbreak of war to house British and Polish codebreakers.

Bletchley Park itself is now a tourist attraction. The news is that a display reorganization has caused the Turing Welchman Bombe Rebuild Trust that owns the Bombe to approach the neighboring National Museum Of Computing with a …read more http://pje.fyi/QGpKLk

Will John Deere Finally Get Their DMCA Comeuppance?

When it comes to activism, there are many different grades of activist aside from the few who you may encounter quietly and effectively working for change in their field. There are the self-proclaimed activists who sit in their armchairs and froth online about whatever their Cause is, but ultimately aside from making a lot of noise are pretty ineffectual. Then there are the Rebels With A Cause, involved in every radical movement of the moment and always out on the streets about something or other, but often doing those causes more harm than good. Activists can be hard work, at …read more http://pje.fyi/QFyGND

What’s Coming In KiCad Version 5

Way back in the day, at least five years ago, if you wanted to design a printed circuit board your best option was Eagle. Now, Eagle is an Autodesk property, the licensing model has changed (although there’s still a free version, people) and the Open Source EDA suite KiCad is getting better and better. New developers are contributing to the project, and by some measures, KiCad is now the most popular tool to develop Open Source hardware.

At FOSDEM last week, [Wayne Stambaugh], project lead of KiCad laid out what features are due in the upcoming release of version 5. …read more http://pje.fyi/QFsdCP

SiFive Introduces RISC-V Linux-Capable Multicore Processor

Slowly but surely, RISC-V, the Open Source architecture for everything from microcontrollers to server CPUs is making inroads in the community. Now SiFive, the major company behind putting RISC-V chips into actual silicon, is releasing a chip that’s even more powerful. At FOSDEM this weekend, SiFive announced the release of a Linux-capable Single Board Computer built around the RISC-V ISA. It’s called the HiFive Unleashed, and it’s the first piece of silicon capable or running Linux on a RISC-V core.

The HiFive Unleashed is built around the Freedom U540 SOC, a quad-core processor built on a 28nm process. The chip …read more http://pje.fyi/QDvvjP

Search for Military Satellite Finds One NASA Lost Instead

[Scott Tilley] was searching for radio signals from the Air Force’s top-secret ZUMA satellite. He found something that is — we think — much more interesting. He found NASA’s lost satellite called IMAGE. You are probably wondering why it is interesting that someone listening for one satellite found another one. You see, NASA declared IMAGE dead in 2005. It went silent unexpectedly and did not complete its mission to image the magnetosphere.

NASA did a failure review and concluded that in all likelihood a single event upset caused a power controller to trip. A single event upset, or SEU, is …read more http://pje.fyi/QCpmC8

Hackaday Belgrade Call For Proposals Now Open!

Prepare yourself for the return of Hackaday Belgrade! Our premier European conference — Hackaday Belgrade — is on 26 May and we want to hear what you’ve been working on. The Call for Proposals is now open. We seek talks and workshops exploring the most interesting uses of technology and the culture that goes along with it. This includes design, prototyping, research, manufacturing, and the stories of people and progress that move hardware hacking forward.

We’ve booked Dom Omladine for the event because it was perfect for our previous Belgrade conference in 2016. The sold-out conference became a living organism …read more http://pje.fyi/QCKGt9

LED Stand For Lego Saturn V Boldly Goes Where No Lego Has Gone Before

Hackers everywhere have spent the last couple of weeks building the remarkable Saturn V Lego models that they got for the holidays, but [Kat & Asa Miller] decided to go an extra step for realism: they built a stand with LED lights to simulate launch. To get the real feel of blast off, they used pillow stuffing, a clear acrylic tube and a string of NeoPixel LEDs. These are driven by an Adafruit Trinket running code that [Asa] wrote to create the look of a majestic Saturn V just lifting off the launchpad with the appropriate fire and fury.  They …read more http://pje.fyi/QB4Z4R
