The Ifs Make Learning to Code Child’s Play

Anyone who has done the slightest bit of programming knows about the “Hello, World!” program. It’s the archetypal program that one enters to get a feel for a new language or a new architecture; if you can get a machine to print “Hello, World!” back to you, the rest is …read more

Understanding Elliptic Curve Cryptography And Embedded Security

We all know the usual jokes about the ‘S’ in ‘IoT’ standing for ‘Security’. It’s hardly a secret that security in embedded, networked devices (‘IoT devices’) is all too often a last-minute task that gets left to whichever intern was unfortunate enough to walk first into the office that day. …read more

Automate Your Comfort Food Prep with an IoT Grilled Cheese Robot

What exactly qualifies as comfort food is very much in the palate of the comfortee. Grilled cheese may not work for everyone under every circumstance, but we’ll risk a bet that the gooey delicacy is pretty close to universal, especially when you’re under the weather.

But if you’re too sick to grill up your own and don’t have anyone to do it for you, this grilled cheese sandwich-making robot might be the perfect kitchen accessory. Dubbed “The Cheeseborg” and built as a semester project by [Taylor Tabb], [Mitchell Riek], and [Evan Hill] at Carnegie-Mellon University, the bot takes a few …read more

Howto: Docker, Databases, and Dashboards to Deal with Your Data

So you just got something like an Arduino or Raspberry Pi kit with a few sensors. Setting up temperature or motion sensors is easy enough. But what are you going to do with all that data? It’s going to need storage, analysis, and summarization before it’s actually useful to anyone. You need a dashboard!

But even before displaying the data, you’re going to need to store it somewhere, and that means a database. You could just send all of your data off into the cloud and hope that the company that provides you the service has a good business model …read more

State Machine Controls Garage Door Over The Internet

Home automation has been a hot-button topic time and again since the dawn of the personal computer age. These days, thanks to modern communications technology, it’s possible to do some pretty cool stuff. [Brad Harbert] decided to automate his garage door, controlling it over the Internet.

The build relies on a Particle Photon to do the heavy lifting of connecting the door to the Internet. Particle offer a cloud service that makes setting up such a project easy for the first timer, and [Brad] was able to get things working quickly. A relay is used to activate the garage door …read more

DIY Mini Helical Antennas From Salvaged Co-ax Cable

[Mare] has a visual guide and simple instructions for making DIY mini helical 868 MHz antennas for LoRa applications. 868 MHz is a license-free band in Europe, and this method yields a perfectly serviceable antenna that’s useful where space is constrained.

The process is simple and well-documented, but as usual with antenna design it requires attention to detail. Wire for the antenna is silver-plated copper, salvaged from the core of RG214U coaxial cable. After straightening, the wire is wound tightly around a 5 mm core. 7 turns are each carefully spaced 2 mm apart. After that, it’s just a matter …read more
