“A timepiece that allows to stop and think about the essence of time, and also a fun project to build! Binary Clock Prototype Building a binary clockBackgroundA couple of years ago I wanted to try out some iot-related stuff. I bought a couple of Arduino-boards and some random components and started fiddling around. At first I started out by trying …

“Tides. In Anchorage Alaska we live on a point located between two enormous tidal bays—so big in fact that Captain Cook on his initial survey of the area thought (hopeful thinking) that this entrance would prove to be a “northwest passage”. It is shallow and all boats traversing to the port are aware of the difficulties involved with a …

“One of the problems for an office worker is a very busy schedule, leaving early and coming home late, so they can not turn on lights or other equipment when night falls. Or it could be, they rush to go to the office, so forget to turn off other electronic equipment. Another problem, a company requires timeliness to automatically turn …

“This alarm clock is an attempt to get our toddler to stay quiet in the morning while we try to continue sleeping. My wife asked me, “do you mind if I spend $27 on a toddler alarm clock?” When I figured out what such an alarm clock does, I decided I could make that from parts I had in my …

“Control an HVAC register with a servo to improve room comfort throughout the day Like most US homes, our 1000sqft house is heated and cooled by forced air in a single zone. There is one thermostat which turns the system on or off, and all areas are fed hot or cold air at the same time. Ideally, with the airflow …

“In this instructable, I would like to explain how to build a powerful smart Bluetooth speaker in a very simple way. The radios made a revolution in the 20th century every NEWS including war alerts were sent through the radio communication only. But the due to the use vacuum tubes during those days, size of radios were very big and …

“Everyone with pet fish, either in a pond or an aquarium, has had the issue of not being able to feed them when on holiday. To solve this, I decided to make an automatic fish feeder. Since my fish are in a pond outside, I wanted to make this project solar powered. The feeder also allows you to feed them …

“8 Digit 7 Segment MAX7219 Module is an amalgamation of two pieces of 0.56” 4 Display 7 Segment Common Cathode Module which is mounted or arranged horizontally and controlled by MAX7219 driver. The advantages of this module is that it only takes 3 pins of I/O as a communication on arduino, so as to minimize the use of …

“The goal of this tutorial is for you to build a fully functioning meteor detection video camera which you will be able to use later on for meteor detection and observations. The materials used will be relatively cheap, and can be easily bought in your local tech store.”

“Dallas Semiconductor, now owned by Maxim Integrated, is well known for making some excellent real-time clocks (RTCs). Take, for example, the DS1307: it’s simple, works with essentially any cheap 32,768 Hz watch crystal, is easily accessible over I2C, and is extremely power efficient (500nA current when running the oscillator on battery power). As great as it is, the …
