Millions of farmers in the world each year face loss of their crop. Its mainly due to crop disease or environmental problems like nature of soil (pH), poor quality of air, and excessive or very low moisture in soil. To get cure from these problems, farmers need to know the fertilizer according to the condition

I recently found six 2.3″ red 7 segment displays in my collection which I purchased from Rapid Electronics when they were clearing out non-RoHS stock. Since I have no clock at my work bench I decided to construct one from some prototyping pad board, a Microchip PIC18F26K20 microcontroller and a Dallas DS32KHZ temperature compensated 32.768kHz

You certainly all know that you cannot trust Wikipedia completely. In our case, it’s not about the lack of credibility but more about incompleteness. It is generally respected that there are more things that belong in the area of nanotechnologies – when something needs to be done from scratch, iPod Nano or Nano-SIM card holder.
FUN but REAL: Nanotechnologies already in SOS electronic… Read More »
The purpose of this article is to demonstrate how you can perform serial port communication in the VBA (Visual Basic Applications – script editor included in any typical Microsoft Excel distribution) but without using the MSComm control or any other third party add-on or ActiveX. 1. Introduction The great advantage of this method, which uses

DoE 2016 is a known term naming stringent regulations established by DoE (department of energy USA) valid from year 2016. Among other things it brings a requirement for a standby power consumption of small adapters to be below 0.1W. In Europe we have here a limit of 0.5W for majority of small adapters, but even
