Collaborate Disseminate
Recycling beverage cartons isn’t 100% efficient. The process yields some unusable garbage as a byproduct. Why? Because containers like juice boxes are mostly paper, but also contain plastic and aluminum. The recycling process recovers the paper fibers for re-use, but what’s left after that is a mixture of plastic rejects …read more

[Dave Akerman]’s interest in high-altitude projects means he is no stranger to long-range wireless communications, for which LoRa is amazingly useful. LoRa is a method of transmitting at relatively low data rates with low power over long distances.
Despite LoRa’s long range, sometimes the transmissions of a device (like a …read more

Putting a 3D printer on a mobile robotic platform is one thing, but two robots co-cooperatively printing a large object together is even more impressive. AMBOTS posted the video on Twitter and we’ve embedded it below.
The robots sport omnidirectional wheels and SCARA format arms, and appear to interact with …read more

3D printing is well-suited to cranking out tank tread designs, because the numerous and identical segments required are a great fit for 3D printing’s strengths. The only hitch is the need for fasteners between each of those segments, but [AlwynxJones] has a clever solution that uses plentiful hard plastic spheres …read more

[ROBAGON] makes miniature, 3D-printable gaming terrain and features like these stone pillars with flickering torch. His model isn’t free to download (though it’s under $2 at the time of writing), but the part that impressed us was his clever way of using electric tea lights to create a flickering torch …read more

[Nick Chen] shared some fascinating and useful details about building a AN/PVS-14 monocular night vision device from parts. It’s not cheap, but the build would be a simple one for most Hackaday readers, at least the ones who are residents of the USA. Since the PVS-14 is export controlled under …read more

[Glen]’s project sounds perfectly straightforward: have a big industrial-style push button act as a one-key USB keyboard. He could have hacked something together in any number of ways, but instead he decided to create a truly elegant solution. His custom PCB mates to the factory parts perfectly, and the USB …read more

For those hosting their own git repositories there are a number of solutions for creating convenient web-accessible front ends, but [mitxela] wasn’t quite satisfied with any of them. After trying a number of alternatives and reflecting on his requirements, he realized that all he really needed was a summary page …read more

Did you ever see a thin metal tab bonded to a battery terminal with little pock marks? That’s the work of a spot welder. Spot welding is one of those processes that doesn’t offer much in the way of alternatives; either one uses a spot welder to do the job …read more
[Adam Haile] has been spending some time improving his CNC router and his latest change is a custom wasteboard with improved bed support. Not only does the MDF wasteboard have plenty of threaded inserts to make for easy clamping solutions, but [Adam] replaced the frame underneath the board with a …read more
