Dip Your Toes in the Open Water of Raspipool

If you’re lucky enough to have a swimming pool, well, you may not feel all that lucky. Pools are great to have on a hot summer day, but keeping them crystal clear and pH-balanced is a deep dive into tedium. Sure, there are existing systems out there. They cost a …read more

Automatic Cut-Off Saw Takes The Tedium Out Of A Twenty-Minute Job

For [Turbo Conquering Mega Eagle], the question was simple: Do I spend 20 minutes slaving away in front of a bandsaw to cut a bunch of short brass rods into even shorter pieces of brass rod? Or do I spend days designing and building an automatic cutoff saw to do …read more

Autodrop3D Continues Working At 3D Printer Automation

It is an unfortunate fact that 3D printers spend most of their time sitting idle, waiting for a human to remove finished prints or waiting for the next print to start. Hackers see such inefficiency as an open invitation to devise a better way, and we’ve seen several innovative ideas …read more

GoPro Factory Goes Nomad to Dodge Tarrif Threat

Despite the fact that the United States and China are currently in the middle of a 90-day “cease fire” in their ongoing trade war, with new tariffs on hold until March 2019 while the two countries try to reach agreement, not everyone is waiting around to see who comes out on top. In a recent press release, action camera manufacturer GoPro has announced their intention to move some production out of China in the face of potential tariff expansions; which many analysts fear will be the result of the current stalemate. That’s right, only some of their production is moving. …read more

Watch The Low-Cost Mechatronics Lab Dispense Candy, Sort Cups

A lot can be done with simple motors and linear motion when they are mated to the right mechanical design and control systems. Teaching these principles is the goal behind the LCMT (Low Cost Mechatronics Trainer) which is intended primarily as an educational tool. The LCMT takes a “learn by doing” approach to teach a variety of principles by creating a system that takes a cup from a hopper, fills it with candy from a dispenser, then sorts the cups based on color, all done by using the proper combinations of relatively simple systems.

The Low Cost Mechatronics Trainer can …read more

Set Up A Headless Raspberry Pi, All From Another Computer’s Command Line

There are differences between setting up a Raspberry Pi and installing an OS on any other computer, but one thing in common is that if you do enough of them, you seek to automate the process any way you can. That is the situation [Peter Lorenzen] found himself in, and his solution is a shell script to install and configure the Raspberry Pi for headless operation, with no need to connect either a keyboard or monitor in the process.

[Peter]’s tool is a script called rpido, and with it the process for setting up a new Raspberry Pi for …read more

Add Nest Functionality to your Thermostat for $5

The Nest Thermostat revolutionized the way that people control the climate in their homes. It has features more features than even the best programmable thermostats. But, all of the premium features also come at a premium price. On the other hand, for only $5, a little coding, and the realization that thermostats are glorified switches, you can easily have your own thermostat that can do everything a Nest can do.

[Mat’s] solution uses a Sonoff WiFi switch that he ties directly into the thermostat’s control wiring. That’s really the easy part, since most thermostats have a ground or common wire, …read more

New Part Day: Put An Alexa In Everything

The last great hope for electronics manufactures is smart home assistants. The Alexas and Siris and OK Googles are taking over homes across the country. At its best, it’s HAL 9000, only slightly less homicidal. It will entertain your children, and you can order cat litter just by saying you want cat litter. This is the future, whether we like it or not.

In an attempt to capture the market, Amazon has released the Alexa Connect Kit. This is an Amazon-Echo-On-a-Chip — a piece of hardware that adds Alexa to microwaves, blenders, and whatever other bit of home electronics you …read more
