This project was completed by Alexandra Pittiglio, Christelle El Feghali and Christian Steixner for our Computational Design and Digital Fabrication ‘Material Manipulation Machine’ Project, Semester 2, ITECH M.Sc Programme Step 1: Concept How can the material and machine be one entity We wanted to explore how a material-machine can be informed by its shape change. …
Introduction / Why this project In 2016 I build my first fish feeder, see Fish Feeder 1. The feeder worked fine for more then half a year. After that period the servos were worn out, causing the program to halt, without sending an error-mail. Oops. I didn’t had the time to correct this fault, because the aquarium …
Story After some my Arduino project remains unclaimed touchscreen, so I decided to realize my chidhood dream to create a chess program. After a couple of months it wins me, but it is not big deal because i do not have any chess rating, just amateur. This project uses Arduino Mega 2560 because of lack …
A group of Researchers from Purdue University in Lafayette, Indiana demonstrated the effect called negative capacitance by making a new type of more energy efficient transistor. This new kind of Field Effect Transistor (FET) proves a theory introduced in 2008 by Supriyo Datta, the Thomas Duncan Distinguished Professor of Electrical and Computer Engineering, and Sayeef Salahuddin, who is a professor of Electrical Engineering and …

Most of smartphones parts are made of silicons and other compounds, which are expensive and easily-breakable. This problem is making all of smart devices manufacturers looking for stronger and cheaper solutions. By combining a set of materials, a group of researchers have successfully discovered a new material which could finally finish the disaster of cracked smartphone …
I got a couple of Microsemi’s C900502 10.525 GHz X-band Doppler radar motion sensors a while ago. This batch was made in UK and had “UK patents 2243495 and/or 2253108 apply” printed on the case. I have seen a teardown of an HB100 Doppler radar module before and was wondering if I this one is …

Researchers at the University of Houston reported in the journal Nature Communications the discovery of a new design that significantly improves the development of a battery based on magnesium. Magnesium batteries are considered as safe resources of power supply – unlike traditional lithium-ion batteries. They are not flammable or subject to exploding – but their ability to store energy is …

Conductivity is the ability of a material to transfer electrons. It is the opposite of the concept of resistivity which is well known to electricians. However, while we are used to address the topic of conductivity in the field of electronics, things get a little bit more complicated when we try to apply the concepts …
To measure high levels of direct current for overload detection and protection, designers frequently use either a current-shunt resistor or a toroidal core and Hall-effect magnetic-field sensor. Both methods suffer from drawbacks. For example, measuring 20A with a 10-mΩ resistor dissipates 4W of power as waste heat. The Hall-effect sensor delivers accurate measurements and wastes …

A new prototype of a lithium-sulphur battery – which could have five times the energy density of a typical lithium-ion battery – overcomes one of the key hurdles preventing their commercial development by mimicking the structure of the cells which allow us to absorb nutrients. This gets us a long way through the bottleneck which …

When I was working on the the latest version of the Common Parts Library, I realized that it would be helpful to explain why you might pick one type of inductor over another. We started off this series by writing “How to select a capacitor,” followed by “How to select a resistor,” and are continuing …
