Hacker Abroad: Massive Conference Brings Big News of Hackaday Prize China

My first full day in China was spent at Electronica, an absolutely massive conference showcasing companies involved in electronics manufacturing and distribution. It’s difficult to comprehend how large this event is, filling multiple halls at the New International Expo Center in Shanghai.

I’ve seen the equipment used for PCB assembly many times before. But at this show you get to see another level below that, machines that build components and other items needed to build products quickly and with great automation. There was also big news today as the 2019 Hackaday Prize China was launched. Join me after the break for a look at this equipment, and more about this new development for the Hackaday Prize.

New Contest: Flexible PCBs

The now-humble PCB was revolutionary when it came along, and the whole ecosystem that evolved around it has been a game changer in electronic design. But the PCB is just so… flat. Planar. Two-dimensional. As useful as it is, it gets a little dull sometimes.

Here’s your chance to break out of Flatland and explore the third dimension of circuit design with our brand new Flexible PCB Contest.

We’ve teamed up with Digi-Key for this contest. Digi-Key’s generous sponsorship means 60 contest winners will receive free fabrication of three copies of their flexible PCB design, manufactured through the expertise of OSH Park. So now you can get your flex on with wearables, sensors, or whatever else you can think of that needs a flexible PCB.

Making Digi-Key much, much prettier

digi

We all love Digikey, but of all the major component retailers out there, their web interface really isn’t that great. A lot of online sources for parts are much, much prettier, but nothing a good Greasemonkey script can’t fix. This is all the work of [Ben], and adds a ton of really, really useful features to the Digikey web interface.

First up is a whole bunch of pictures right at the top of the search results. If you’re looking for pin headers or weird connectors, this is an astonishing useful feature that will help you select the right part faster. After that is a ‘helper’ button for voltages. As you know, selecting a part with a 5V input requires clicking multiple options including 3.3-5V, 2.3-6V, and 5-40V. Clicking on the helper button and entering 5 V will select all the entries in the filter that contain a 5V part.

[Ben]’s project has been tested with Firefox and Chrome with Greasemonkey extensions. Head on over to his project page for a much better demo of all the features for this really great tool.
