A working model of memoristor has been fabricated by a team of engineers at Hewlett-Packard. The memristor is an element in which the magnetic flux is a function of the accumulated electric charge in the device. In otherwords they have the ability to remember the amount of charge that has flowed through them. For the… Continue reading Memristor
I have been trying to develop a general purpose prototyping board for the Microchip PIC 16F877A . My aim is to build a board with the following features a) All ports and other on board devices must be easily taken out to a solderless bread board. b) In circuit serial programming. c) boot loader. d)… Continue reading Building a PIC 16F877 prototyping board-Part1 Programmer
I have seen several tutorials on the Internet for making professional looking PCBs at home. In fact, I attempted making a few last year with limited success. However, I managed to perfect the technique yesterday. The procedure I used is described in this tutorial. I made some minor changes to materials and made a few… Continue reading Building Printed Circuit Boards at home
I will describe my experiences in receiving long distance FM here. For receiving long distance FM (or FM Dxing) the first thing you need is a good radio. Good receivers are hard to find nowadays. If you can find a Phillips of Sony radio you are half way through. (I think Phillips no longer markets… Continue reading The art of Long Distance FM DXing
My ham radio licence has definitely rekindled my interest in electronics. While searching for some information I have come across the following forums. http://www.electronics-lab.com/ http://www.electro-tech-online.com/ http://www.dutchforce.com/~eforum/ All of then are invaluable resource to home brewers. Electronics lab forum has some excellent howtos and construction ideas. They also have a resources forum where you can find… Continue reading Electronics forum
