A team of researchers with members from the University of California and Rice University has found a way to get a flat transistor to defy theoretical limitations on Field Effect Transistors (FETs). In their paper published in the journal Nature, the team describes their work and why they believe it could lead to consumer devices […]

– Arduino Uno ($25) – 32 x 16 LED Matrix ($20) – Breadboard ($5) – Jumper Cables ($5) – USB A to B Cable ($3) – Computer – 5V 2Amp Power Supply ($10) – A basic understanding of coding in C In order to create this project, many physical materials are necessary, a lot of
Overview This project was done for a Friend Of a Friend. He needs to monitor water flow rate and quantity for his solar heating projects. He is mainly interested in this two inch sensor but also sent along a small plastic hose bib type similar to the Adafruit 828. Both of these sensors are turbine
Ultimamente tenho andado a testar um display TFT de 2.4″ PBC ILI9341 com touch adquirido na ebay por menos de 8euros! Este display gráfico é uma excelente aposta tanto para pequenos projectos como para projectos mais avançados pois inclui a capacidade de leitura de imagens armazenadas em cartão SD. Tem uma resolução de 240×320 RGB.

Summary Electrical accidents are rapidly increasing especially electric line repairs incident due to the lack of communication and coordination between the maintenance personnel and the electric substation staff. The password based circuit breaker device could just be the solution as only the lineman could reliably control the circuit breaker to avoid miscommunication. The system requires
Hey guys, back with another little project that I’ve been fiddling with for the past week. With kids around, every parent is thinking how to make their home safer for the little ones and for everybody in general. One of the most dangerous thing in the house can be the stove and since we have

ermometer with DS18B20 digitaltemperature sensor using Arduino, breadboard, jumpers. So you can measure temperature of the air, liquids like water and the temperature of the ground. *prints the temperature data on the serial monitor of the arduino IDE. DS18B20 is 1-Wire digital temperature sensor from Maxim IC. Reports degrees in Celsius with 9 to 12-bit
