Your 3D Printer Could Print Stone

Posted on by

Most of our  3D printers print in plastic. While metal printing exists, the setup for it is expensive and the less expensive it is, the less impressive the results are. But there are other materials available, including ceramic. You don’t see many hobby-level ceramic printers, but a company, StoneFlower, aims to change all that with a print head that fits a normal 3D printer and extrudes clay. You can see a video of the device, below. They say with some modifications, it can print other things, including solder paste.

The concept isn’t new. There are printers that can do this …read more

Real-Life Electronic Neurons

Posted on by

All the kids down at Stanford are talking about neural nets. Whether this is due to the actual utility of neural nets or because all those kids were born after AI’s last death in the mid-80s is anyone’s guess, but there is one significant drawback to this tiny subset of machine intelligence: it’s a complete abstraction. Nothing called a ‘neural net’ is actually like a nervous system, there are no dendrites or axions and you can’t learn how to do logic by connecting neurons together.

NeruroBytes is not a strange platform for neural nets. It’s physical neurons, rendered in PCBs …read more

The Sounds of Silence? Muzo Fails to Deliver

Posted on by

If you fly much or work in a loud office, you know that noise-canceling headphones can be a sanity saver. Wouldn’t it be nice if you could just have noise-canceling without the headphones? Apparently, a lot of people think that’s a good idea and funded a project called Muzo. [Electroboom] borrowed one and — mystified how such a device could work — set out to test it. Along the way, in the video below, you can see him do a neat demonstration with two speakers canceling each other in his closet.

Based on [Electroboom’s] tests and the tests from other …read more

A Modern, Upgraded BASIC Stamp

Posted on by

Back in the Before Times, when microcontroller development required ultraviolet light, building anything was a pain. You probably had to burn a ROM onto a chip with a parallel programmer, there was no in-circuit programming, and who knows what would happen if you needed a serial port.

This changed in the early 90s with the introduction of the BASIC Stamp from Parallax. This was a simple microcontroller development board using Microchip PIC. With a little bit of clever firmware developed by Parallax, you could write code in BASIC, upload your code over a serial or parallel port (which every computer …read more

CNC Robot Makes a Move

Posted on by

Another day, another Kickstarter. While we aren’t often keen on touting products, we are keen on seeing robotics and unusual mechanisms put to use. The Goliath CNC has long since surpassed its $90,000 goal in an effort to put routing robots in workshops everywhere.

Due to their cost and complexity, you often only find omni-wheels on robots scurrying around universities or the benches of robotics hobbyists, but the Goliath makes use of nine wheels configured as three sets in a triangular pattern. This is important as any CNC needs to make compound paths, and for wheeled robots an omni-wheel base …read more

Cheap, Full-Duplex Software Defined Radio With The LimeSDR

Posted on by

A few years ago, we saw the rise of software-defined radios with the HackRF One and the extraordinarily popular RTL-SDR USB TV tuner dongle. It’s been a few years, and technology is on a never-ending upwards crawl to smaller, cheaper, and more powerful widgets. Now, some of that innovation is making it to the world of software-defined radio. The LimeSDR Mini is out, and it’s the cheapest and most capable software defined radio yet. It’s available through a Crowd Supply campaign, with units shipping around the beginning of next year.

The specs for the LimeSDR mini are quite good, even …read more

A Smaller, Cheaper RISC V Board

Posted on by

Early this year, the world of electronics saw something amazing. The RISC-V, the first Open Source microcontroller was implemented in silicon, and we got an Arduino-derived dev board in the form of the HiFive 1. The HiFive 1 is just a bit shy of mindblowing; it’s a very fast microcontroller that’s right up there with the Teensy when it comes to processing power. There’s support for the Arduino IDE, so all those fancy libraries are ready to go. That’s not to say there aren’t a few problems; it’s a relatively expensive board, and it does use the ubiquitous but somewhat …read more

False Claims On Kickstarter: What’s New?

Posted on by

Kickstarter and its ilk seem like the Wild West when it comes to claims of being “The world’s most (Insert feature here) device!” It does add something special when you can truly say you have the world record for a device though, and [MellBell Electronics] are currently running a Kickstarter claiming the worlds smallest Arduino compatible board called Pico.

We don’t want to knock them too much, they seem like a legit Kickstarter campaign who have at time of writing doubled their goal, but after watching their promo video, checking out their Kickstarter, and around a couple of minutes research, …read more

Friday Hack Chat: Crowd Supply

Posted on by

Crowdfunding is a mixed bag, at best. On one hand, you have fantastically successful products like Pebble, Oculus, and the Kano personal computer that managed to take in money, turn out a product, and become a successful company. (If even just for a while, the Pebble was great.) On the other hand, you have obvious scams like a color-picking pen that are run by a literal Nigerian scammer.

Crowd Supply is different. Unlike other crowdfunding platforms, to get on Crowd Supply you’ll need a working prototype. Where other platforms can measure their success by how many campaigns were successfully funded, …read more

JeVois Machine Vision Camera Nails Demo Mode

Posted on by

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
