What’s inside the new Pebble Time Smartwatch? Dave does a teardown after taking it through the torture test, and gives it a close up view with the Tagarno microscope. How easy is it to disassemble and replace the battery? How much do the components cost? What is the manufacturing quality like? How does the Bluetooth […]

JeVois, which can be translated from French as: I see, is an open-source quad-core camera that can be connected easily with your project whether you are using Arduino, Raspberry Pi or just running it on your PC. JeVois contains a video sensor, quad-core CPU, USB video and a serial port in only 1.7 cubic inches.

Traditionally, asic developments are thought to be the domain of high volume applications. Whilst these designs grab the headlines there are many designs that are successfully undertaken for smaller volume product markets. An example of this is the mixed signal asic for industrial controllers. These controllers cover many industries and come in many forms. The
Mixed-signal asics are good even for smaller volume products Read More »
Without problems and directly at connecting a device. How? With a new Euroclamp MPF03 terminal block with integrated fuse holder. 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

With a little practice, you can make excellent double-sided PCBs by combining a laser cutter with chemical etching. The basic idea is: the laser cutter blasts away spray painted etch resist, then chemicals eat away the exposed copper. Once the copper is gone, the underlying board can be cut again with the laser to make

A processor is a collection of logic circuits that is designed to efficiently process data. There are a number of processors – processor designs are created for specialised tasks, these include the Central Processing Units (CPU), Graphics Processing Units (GPU), Physics Processing Units (PPU) or Digital Signal Processors. An array or vector processor solves computational

The PIC16F170X/171X family features Core Independent Peripherals, such as the Configurable Logic Cell (CLC), Complementary Output Generator (COG) and Numerically Controlled Oscillator (NCO). These “self-sustaining” peripherals take 8-bit PIC® MCU performance to a new level, as they are designed to handle tasks with no code or supervision from the CPU to maintain operation. As a
I recently received an external USB battery as a promotional gift (see image below). While I always thought of these as a superfluous gimmick, I realized that these devices could be quite useful as mobile power source for various projects. After all, dealing with lithium ion batteries in your own projects can be dangerous and

Have you been using float or double variables to perform mathematical operations on embedded systems without a Floating-Point Unit (FPU)? You are doing it wrong! That’s incredibly inefficient. Use fixed-point representation instead. An FPU is an hardware block specially designed to carry on arithmetic operations on floating point numbers. Even though the C/C++ code may work without an
