The neuron The neuron can be divided in three main parts: Dendrites, Soma, Axon (Figure 1). Dendrites are prolongations of the soma in shape of trees (dendros in Greek) and they receive most of the excitatory signals. The soma contains the nucleus of the cell and is where most of the proteinic synthesis occurs. The […]
Drones are one of the rising technologies in the world and it became very popular that we see it in news on places that have armed conflicts, aerial photography like GoPro drones and even for customer care like the Prime Air delivery system from Amazon which is designed to get packages to customers using small
Some time ago I’ve build a prototyping board with graphical LCD. It have served for various small projects and prototypes. Had a spare temperature sensor DS18B20 and decided to put simple temperature display project. GLCD board is equipped with Atmega32 microcontroller running at 16MHz. DS18B20 sensor is connected to port D pin 6. LED connected

The Text Video Display is complete! I’ve discovered a simple microcontroller and have taken a new approach to create a 40×25 monochrome text display. I am using an Atmel ATMega8 controller which contains 1k of SRAM and 8K of Flash ROM. I store the character data in the SRAM and the font
Introduction devDuino Sensor Node V 4 is a compact Arduino-compatible microcontroller and is designed to build wireless networks based on transceiver nRF24L01+. You can easily connect other sensors or actuators to this platform, to build your remote monitoring or controlling system. Unlike the version 1,2,3 is on board built-in sensor temperature and humidity. Model:103990074 Feature
audiogetavarage is a simple library you can use to interface with an audio input. It reads data from an ADC pin and returns the RMS value of the input simply using rms avarage. The root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of
For my monthly maker column in Dutch newspaper “De Volkskrant”, I made a coolbox in which you can control the temperature in three separate compartments to keep craft beer at just the right temperature. The contraption I build uses three Peltier-elements to cool, an old desktop computers power source, an LCD to show both the
Choosing components is a series of time-consuming tasks, from surveying the market for possible candidates to properly evaluating performance. As a hardware engineer who has worked in Silicon Valley for 10 years, I have spent significant time developing test plans and specs, building fixtures, and testing components. One of the reasons comparing components takes a
An implantable, microchip-based device may soon replace the injections and pills now needed to treat chronic diseases: Earlier this month, MIT spinout Microchips Biotech partnered with a pharmaceutical giant to commercialize its wirelessly controlled, implantable, microchip-based devices that store and release drugs inside the body over many years. Invented by Microchips Biotech co-founders Michael Cima, the
Summary The solar energy collection is not that easy compared to the different types of power generation system because it has the lowest capacity factor. It has 5 out of 24 hours in a day that it can generate electricity from its solar collection. The only solution to this is by optimizing the 5 hours
