Several of our recent projects have used a 16 bit PIC24 microcontroller from Microchip. The PIC24FJ128GC006 contains two 16-bit ADC channels which makes it useful for measuring voltages more accurately than the 10 or 12 bit ADCs you normally find on microcontrollers. We used this microcontroller for the temperature controller on our recent Soldering Robot […]
A low-magnification tunneling electron microscope (TEM) image of Gr–Si nanoparticle (NP). (b) A higher-magnification image for the same Gr–Si NP from the white box in a. (Insets) The line profiles from the two red boxes indicate that the interlayer spacing between graphene layers is ~3.4 Å, in good agreement with that of typical graphene layers based

Bench power supplies aren’t really pieces of kit that get your pulse racing, they just sit there doing their job, in some cases giving gentle background heating to keep the lab warm in the winter and providing enough ballast to stop your bench wobbling about too much. The traditional bench top power supply always came

DC-DC converters are widely used components that convert DC power from one voltage to another, producing a regulated output voltage. These devices are used in many electronic products, including laptops, mobile phones, and instrumentation. Like any device, DC-DC converters need to be characterized by manufacturers and by engineers evaluating them for a design. Given the
This is a brief review of the capabilities and ease of use of three of the most interesting, innovative and downright disruptive web-based EDA tools: EasyEDA Upverter Autodesk 123D Circuits (formerly Circuits.io) The same simple astable multivibrator circuit is entered into each tool and the design process followed through simulation (where offered), to PCB layout

O facto de ter uma CNC disponível em casa deu-me liberdade para contruir mais facilmente e rápidamente peças que antes demorariam algum tempo a fabricar e que muito provavelmente não iriam ficar tão perfeitas. Isto fez com que novas ideias que me surgissem fossem mais facilmente postas em prática. Esta foi uma dessas ideias e
We´d like to share with you its parameters, as well as hints, which can make your work with this module easier – this is our biggest bonus to sale of modules from company Quectel. Are you interested in compatibility with previous modules? Module EC20 arises from the M10 GPRS module and the UC20 UMTS module.
When we need precision and repeatability, a stepper motor is always the solution. With the way it is designed, a stepper can only move from one step to the next and fix in that position. A typical motor has 200 steps per revolution; if we tell the motor to go 100 steps in one direction,
Do you (still) remember the display of your old CD player, HiFi system or car radio? Have you ever noticed the displays used at your local supermarket that shows you the scanned item and the price of it? These displays have a characteristic beautiful bright blue-green colored glow in common: These are so called vacuum

Nowadays, when “almost everything” works on electricity we can see still more devices connected to mains line. That´s why it often happens, that many small-power devices are connected to one (circuit breaker fused) line. To increase a safety, it´s usually advantageous to fuse particular devices separately – for example by small glass fuses. Somewhere it´s
