A microcontroller is a self-contained, but very limited computer — halfway between a computer and a component. The top reasons to integrate a microcontroller into your projects are connectivity and interactivity, and one easy way to get your microcontroller talking with the outside world is standard asynchronous serial I/O. Many devices can communicate this way, […]
With very few exceptions, every electronic circuit needs an oscillator, also referred to as a clock, clock generator, or timing circuit. Its role is to provide the “heartbeat For more detail: MEMS Oscillators Challenge Quartz Crystals in RF Applications

Change list 26 Jul 2015 – added rework instructions for those who want to do it themselves 21 Jun 2015 – new software version to add optional (but default) whitening support between the OneRNG and rngd 20 Apr 2015 – new software version to support another issue with firmware verification – if your board was
This device was built at Recursive Software Development Labs in order to be mounted on a rally car competing in the Estonian National Rally championship. The racing team needed help realizing a reliable measurement device which would output the currently inserted gear on a large, bright led display. The biggest challenge to overcome was that

Today I came across a surprisingly simple approach to installing USBasp and USBtiny drivers for all versions of Windows — XP, 7, 8, 8.1, whether 32-bit or 64-bit, all inclusive! As you may know, installing open-source drivers such as USBasp and USBtiny have been a great pain on some of the recent Windows OS, due

Farnell element14 have announced that they will be stocking the BitScope BS10 measurement device which combines a 2-channel USB oscilloscope, spectrum analyzer, 8-channel logic analyzer and function generator. You can use it with a PC running Windows or Linux, an Apple Mac or even a Raspberry Pi. Sampling rate is up to 40Msample/s giving it
What´s more, M66 is currently the smallest quad band GSM/GPRS moduloe in the world … AT the same time it withstands strong frosts, so it´s ready for a wide spectrum of applications. New extraordinary attractive communication module Quectel M66 asks its place maybe even in your application. Does it deserve it? Most probably yes. Besides
GSM/GPRS module Quectel M66 is proud to be small and that it has a Bluetooth Continue Reading
In this tutorial Dave explains what a PCB spark gap is and how it can be a useful zero cost addition to your PCB layout to help prevent ESD damage. He shows how to easily design them into your board and calculate the approximate voltage rating. And of course has some fun applying 5kV to
I finally finished the next version of my TinyLoadr AVR programming Shield – and it’s not a shield. It’s a standalone USB programmer, so you no longer have to have an extra Arduino laying around. The best part? It’s the same price as the shield was! Read more to find out more about it, or
