It is said that you’re not a sysadmin if you haven’t warmed up a sandwich on server. OK, it’s not widely said; we made it up, and only said it once, coincidentally enough after heating up a sandwich on a server. But we stand by the central thesis: never let a good source of excess […]

Hi everyone, I work as a builder even though I’ve been always really interested in new technologies. I’ve learned a little about 3d printing, Arduino and electronic issues reading a lot. I visit this web regularly so I would like to make my little contribution. In my job sometimes it is not so easy to

In this Instructable we will have a look at modifying a hot-air popcorn machine to turn it into a fully automatic and temperature-controlled home coffee roaster. Roasting coffee at home is surprisingly simple, and even something as basic as a frying pan can do the trick with enough patience and practice. In most basic terms,

Keeping cool saves lives In the developing world, vaccines are the front line of defense against dangerous illnesses such as Ebola, Influenza, Cholera, Tuberculosis and Dengue to name a few. Transporting vaccines and other life-saving materials such as insulin and blood require careful temperature control. First-world logistics tend to break down when supplies are transported

We’ve seen plenty of simple reflow ovens, and there’s an excellent chance that some of the people reading these words have even thrown their own together. A minimal example isn’t much more than a old toaster oven, a Solid State Relay (SSR), a thermocouple, and a microcontroller to get them all talking. But if you’re

Still on the journey to complete an “upcoming project”, “ESP32 NTP Temperature Probe Cooking Thermometer With Steinhart-Hart Correction and Temperature Alarm” is an Instructable showing how I add an NTP temperature probe, piezo buzzer and software to my capacitive touch Instructable “ESP32 Capacitive Touch Input Using “Metallic Hole Plugs” for Buttons” to create a simple
A pyranometer measures the sun’s irradiance (power/area, basically “brightness”) on a surface. Despite the similar names, it is completely different from a pyrometer, so stop right here if that is what you are looking for. This Instructable describes how to build and test a modified version of the pyranometer kit offered by Dr. David Brooks of the

Two other tutorials I have written step you through the basics (Arduino 101) and how to create a really basic data logger (Arduino Datalogger – simple). This tutorial will step through how to attach servo motors, and use temperature sensor to move it! The premise is that often, you want to respond to some input

While there is nothing better than curling up by the fire during winter, the bitterly cold season can wreak havoc on your property. It is, therefore, crucial to prep your home in advance to ensure it can withstand the wear and tear of the arduous weather conditions. If you want to maintain a stunning, warm

Now I think just about everybody has a binary clock and here’s my version. What I enjoyed was that this project combined some woodwork, programming, learning, electronics and perhaps just a little artistic creativity. It shows time, month, date, day of week, temperature and humidity on the marble display in a binary form – an
