Hello everyone! In this instructable I will show you how to make a low cost 3d printer that I designed! It should cost around $150 US dollars or $175 Canadian dollars, if you buy from the links provided in this project (parts are from Aliexpress). You can also buy locally but it will cost more […]
A Nixie Tube is a Neon gas-filled tube, that has a wiremesh anode with various cathodes shaped like numbers or symbols. Back in the 1950s they were used in computers, calculators, and laboratory equipment. Nixie tubes were replaced by LEDs and VFDs(vacuum fluorescent displays)in the 1970s. They were too costly to to mass produce so […]
Are you familiar with Arduino, but are looking for a little more connectivity in your projects? This Instructable goes over a new (and cheap) wireless module that has hit the embedded world hard – the ESP8266. This little module is a perfect way to hook your Arduino project into your WiFi. What you do with […]
My university had a bunch of old server motherboards that were headed to the dumpster. I decided to see the feasibility of turning them into something useful! Go ahead and grab the attached pdf plans, print them out full size, and build your own! Step 1: Prepare the Motherboard Pop in your earbuds, turn up […]
the photo you see was taken from my first ever copter which i built in 2 hours, what i had not mentioned was my first copter used a laser cut frame i designed and produced whilst in school. This difference between this post and my other about building multirotors is this is mainly to do […]
I designed this project for a 10-hour workshop for ChickTech.org whose goal is to introduce teenage women to STEM topics. The goals for this project were: Easy to build. Easy to program. Did something interesting. Low-cost so participants could take it home and continue to learn. With those goals in mind, here were a couple […]
I apologize if you find spelling errors or nonsensical text, my language is Spanish and has not been easy to translate, I will improve my English to continue composing instructables. In today’s technology, especially electronics have come a long way, to the point that today can make projects a few years ago were very complicated […]
Some days ago I bought a laser rangefinder (Uni-T UT390b, f.e. http://www.dx.com/de/p/uni-t-ut390b-45m-laser-dist…) to realise a simple LiDAR. The rangefinder has an accuracy of +/- 2mm and is able to measure distances up to 45m. This will be enough for my living room 😉 You’ll also need: * Arduino Mega (because of more than one Serial […]
This tutorial will explain how to build a machine for biofeedback. But first a bit of theory. What is biofeedback? [Font: Wikipedia | https://en.wikipedia.org/wiki/Biofeedback] Biofeedback is the process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to […]
This is an inexpensive, DIY, Arduino-powered oneironautics device that allows users to alert themselves when they are in a deep dreamstate, without waking up. In other words, this machine will tell you when you are dreaming, while you are dreaming. Why is this such a big deal? Because, this is the first step to achieving a […]
