Starting with robotics can be hard, if you don’t know where and how to start. Best way to start is to make mobile robot. In this step-by-step we will show you, how to make cheap robot with parts available in your local store and household. Before you start you should make some plans how platform […]
Glad to see you have arrived on this page to learn how to build a programmable constant direct current dummy load. This load will allow you to draw a set current from any source. This load can also be set to a constant resistance or a constant power. I have been working in the Electrical […]
A fun, simple LED clock, that will give you the time to the nearest half hour using single-color LEDs. Parts needed are as follows: Arduino Nano 400 tie-point Breadboard Ribbon Cable DS1307 RTC IC 32.768 kHz Crystal (12) 10mm LEDs (12) 180 Ohm resistors (2) 10k Ohm resistors 0.1″ spaced, 12 wire ribbon cable, 7″ […]
Features Arduino 328 Microprocessor is used to decode and display Time & date from the DCF77 “Atomic” Clock in Mainflingen near Frankfurt Germany The DCF77 signal is decoded using the fantastic new DCF77 library written by Udo Klein meaning the clock stays in sync and keeps perfect even with a massive amount of noise on […]
Heating things up is one of the most performed tasks in a lab. Quite a lot of times it is not enough to simply hold something at a certain temperature, but the rate at which something is heated and for how long is just as important. Especially when you try to develop catalysts for chemical […]
Introduction This is the first of two instructables that make up a complete customizable Home Automation for Beginners example. See DIY Home Automation for Beginners for the second part. It is aimed at the absolute beginner. If you can handle a sharp knife without cutting your fingers off you can make and customize this home […]
The following design is for a Solar battery charger ran by an Arduino Nano. It can handle a standard lead acid 12V battery, like for a scooter or a car. Furthermore the design has been tested and runs with 90% efficiency under 70ᵒC (158ᵒF). It can take up to 20V on the input site of […]
What a girl wants. What a girl needs. What’s more exclusive and has more cachet than scoring a Birkin bag? Pow!!! A Batgirl Birkin bag! Holey Haute Couture, Batman! Yes, you too can knock off a version of this famous bag. Okay, even mine started out as a knockoff so you ain’t doing anything iffy […]
Last year the comedy sketch show ‘Portlandia’ made fun of an arts and craft trend, where craft artists would take ordinary items and ‘put a bird on it’. I fell victim to a similar trend in the geek crowd: Take an ordinary silver item and add LEDs to ‘put a cylon in it’. 🙂 When […]
This is a tutorial on how to program your DSLR camera to take photos photobooth-style. It’s a simple Arduino setup that allows you to take continuous photos with 3-second delay intervals. This was built for a college electronics project. A motion sensor detects motion in front of the camera, lights up and shows an LCD […]
