This article will discuss the process of utilizing an Arduino Uno to effectively manage a boost converter with a power output of at least 10 watts. By utilizing only a few components such as an inductor, capacitor, diode, and a FET, it is possible to create a discrete boost converter. Please refer to the Wikipedia

Designing a custom plate for the Arduino Robot, adding jumbo LEDs and displaying readings from an ultrasonic distance sensor to the LCD. My previous post on the Arduino Robot described how I took the Runaway Robot sketch and modified it work with the PING ultrasonic distance sensor. This post is still based around the same

This project details a Flowcode and E-blocks based weather station capable of reading local temperature and humidity with 2 remote thermo-hygrometer sensors. The local board also incorporates a real time clock. This article has been contributed by Flowcode user John Crow. Flowcode can be downloaded and trialled for free at the Matrix Technology Solutions website.
Developing your own Flowcode 7 controlled weather station Continue Reading
For a number of years, my colleague Andrew has had an old IBM mainframe CPU kept in storage, waiting to be transformed into something new. Hailing from a long-lost era of computing (the system in which this module was used was the 4381, first announced in 1983) – this is a far cry from what

I’ve been meaning to put some content on here for a while and recently I got around to getting an Uno and motor shield. Given I also have access to a 3d printer and have a shedload of microswitches, semis and other goodies knocking around – Robocar is an obvious choice! I’ve had a few

Flip Intro There is something kind of magical about swimming when you are a child. Do you remember growing up and watching your shadow as you swam in the pool, trying to mimic a perfect dolphin kick and imagining you were a mermaid rather than human? We all shared these sorts of memories and a
Quite a lot of coffee is consumed at work but real statistics are missing. For the coffee machines with a can it can be interesting to have a visualization with coffee left in can, water in machine, time left until machine is finished, estimated time until can is empty. This would probably require a modified

Project Description DishShamer solves the age-old problem of getting your roommates to wash their dishes. The kitchen is a communal space. When one individual fails to keep this shared environment clean, there can be two outcomes: conflict and socially awkward confrontations, or placing unfair cleaning burdens on the responsible roommates. By tracking who checks out and returns
Chatty Coasters are interactive coasters that listen for silences and insert provocative conversation starters into them. Chatty Coasters are interactive drink holders that listen for silences in conversation and insert provocative questions into them. In order to encourage healthy, thought-provoking conversation in kitchens, Chatty Coaster waits for drinkers to rest their cup on it and breaks
