Accident Forgiveness Comes to GPLv2

Years ago, while the GPLv3 was still being drafted, I got a chance to attend a presentation by Richard Stallman. He did his whole routine as St IGNUcius, and then at the end said he would be answering questions in a separate room off to the side. While the more causal nerds shuffled out of the presentation room, I went along with a small group of free software aficionados that followed our patron saint into the inner sanctum.

When my turn came to address the free software maestro, I asked what advantages the GPLv3 would have to a lowly hacker …read more

Friday Hack Chat: Contributing To Open Source Development

Open Source is how the world runs. Somewhere, deep inside the box of thinking sand you’re sitting at right now, there’s code you can look at, modify, compile, and run for yourself. At every point along the path between your router and the horrific WordPress server that’s sending you this webpage, there are open source bits transmitting bytes. The world as we know it wouldn’t exist without Open Source software.

That said, how does someone contribute to Open Source? Maintainers do like to build their own little kingdoms, so how does anyone break into developing Open Source hardware and software? …read more

Mathieu Stephan : The Making of a Secure Open Source Hardware Password Keeper

Mathieu Stephan is an open source hardware developer, a Tindie seller who always has inventory, a former Hackaday writer, and an awesome all-around guy. One of his biggest projects for the last few years has been the Mooltipass, an offline password keeper built around smart cards and a USB interface. It’s the solution to Post-It notes stuck to your monitor and using the same password for all your accounts around the Internet.

The Mooltipass is an extremely successful product, and last year Mathieu launched the Mooltipass Mini. No, it doesn’t have the sweet illuminated touch-sensitive buttons, but it is a …read more

MakerBot Really Wants You To Like Them Again

For the last couple years, a MakerBot press release has generally signaled that more pink slips were going to be heading out to the already shell-shocked employees at their NYC factory. But just last week something that could almost pass as good news came out of the once mighty 3D printer manufacturer, the unveiling of “MakerBot Labs”. A number of mainstream tech sites heralded this as MakerBot’s first steps back into the open source community that launched it nearly a decade ago; signs of a newer and more thoughtful MakerBot.

Reading the announcement for “MakerBot Labs”, you can almost believe …read more

Drop-in Controller for eBay K40 Laser Engraver Gets Results

[Paul de Groot] wrote in to let us know about a drop-in controller replacement he designed for those economical K40 laser engravers that are everywhere on eBay. With the replacement controller, greatly improved engraving results are possible along with a simplified toolchain. Trade in the proprietary software and that clunky security dongle for Inkscape and a couple of plugins! [Paul] felt that the work he accomplished was too good to keep to himself, and is considering a small production run.

Laser engravers are in many ways not particularly complex devices; a motion controller moves the head in x and y, …read more

JeVois Machine Vision Camera Nails Demo Mode

JeVois is a small, open-source, smart machine vision camera that was funded on Kickstarter in early 2017. I backed it because cameras that embed machine vision elements are steadily growing more capable, and JeVois boasts an impressive range of features. It runs embedded Linux and can process video at high frame rates using OpenCV algorithms. It can run standalone, or as a USB camera streaming raw or pre-processed video to a host computer for further action. In either case it can communicate to (and be controlled by) other devices via serial port.

But none of that is what really struck …read more

Help Wanted: Open Source Oscilloscope on Rigol Hardware

We’ve often heard (and said) if you can’t hack it, you don’t own it. We noticed that [tmbinc] has issued a call for help on his latest project: developing new firmware and an FPGA configuration for the Rigol DS1054Z and similar scopes. It isn’t close to completion, but it isn’t a pipe dream either. [tmbinc] has successfully booted Linux.

There’s plenty left to do, though. He’s loading a boot loader via JTAG and booting Linux from the USB port. Clearly, you’d want to flash all that. Linux gives him use of the USB port, the LCD, the network jack, and …read more

ZeroPhone gives Smartphones the Raspberry (Pi)

There are several open source phones out there these days, but all of them have a downside. Hard to obtain parts, hard to solder, or difficult programming systems abound. [Arsenijs] is looking to change all that with ZeroPhone. ZeroPhone is based upon the popular Raspberry Pi Zero. The $5 price tag of the CPU module means that you can build this entire phone for around $50 USD.

The radio module in the ZeroPhone is the well known SIM800L 2G module. 2G is going away or gone in many places, so [Arsenijs] is already researching more modern devices. An ESP8266 serves …read more

DIY Optical Sensor Breakout Board makes DIY Optical Mouse

Wanting to experiment with using optical mouse sensors but a bit frustrated with the lack of options, [Tom Wiggins] rolled his own breakout board for the ADNS 3050 optical mouse sensor and in the process of developing it used it to make his own 3D-printed optical mouse. Optical mouse sensors are essentially self-contained cameras that track movement and make it available to a host. To work properly, the sensor needs a lens assembly and appropriate illumination, both of which mate to a specialized bracket along with the sensor. [Tom] found a replacement for the original ADNS LED but still couldn’t …read more
