Free/low-cost PADS PCB packages from Mentor/Digi-Key

Two versions of the PADS software package (by Mentor, now a Siemens business) have been made available through distributor Digi-Key. Positioned as design software for “the aspiring innovator” both the free and the $499 versions include access to parts libraries and to a circuit simulator. PADS Maker and PADS MakerPro are intended to give commercially proven technology at an affordable price point. The PADS ...

PIC12F1822 + DS3231 + Remote Control

PIC12F1822 is a small microcontroller has only 8 pins which is not enough for building a real time clock using DS3231 with set buttons because the DS3231 needs 2 pins and the LCD screen needs 3 pins, therefore I've only 1 free pin. I connected that pin to an IR receiver and I used a remote control with a lot of buttons where I used only 3 buttons and the problem solved. This post shows how did I build a sim ...

Graphene could be good for Quantum Computing

Graphene has become an all-purpose wonder material, spurring armies of researchers to explore new possibilities for this two-dimensional lattice of pure carbon. But new research at MIT has found additional potential for the material by uncovering unexpected features that show up under some extreme conditions — features that could render graphene suitable for exotic uses such as quantum computing. The resear ...

WiGPSFi – ESP8266 + GPS

If you love finding solutions that could widen horizons – that is something you will like! I wanted to know what my next ESP projects could connect to – and I decided to look for some open WiFis ….  That is the result after two days programming – and 45 min walking arround. Only for testing this technique – Don´t do this at home, please ?  In this blogpost, you can only read about finding and printing out m ...

PICMAN prototyping board using PIC18LF4553

For a long time now I've been wanting to make my own microcontroller-based prototyping board. My original motivation was the unjustified high costs for even the simplest boards (a basic Arduino for $30 - why???) and the challenge of designing something that anyone can make at home within a few hours, with parts that can be cheaply obtained on eBay. Eventually, I came up with the PICMAN. It is: Based on Micr ...

Frequency Detector using PIC 12F683 Processor

This project describes hardware and software I have developed which allows a small 8 bit PIC microprocessor to function as a single frequency detector or tone decoder. Such a circuit can be used to detect the presence of a certain frequency within an analog signal, such as an audio signal.  I could be used in remote control applications, or to detect musical notes, or for any other situation where a specifi ...
