The Internet-of-Things Power Meter (IPM) is a device fixed on top of the regular household power meter that provides detailed information about the electricity usage. Modern power meters have a LED blinking every time a Watt is used, the IPM detects these flashes using a light sensor, counts them, saves the values to an SD […]

In this tutorial we will learn How to make out PIC projects wireless by interfacing a Bluetooth Module (HC-06). In our previous tutorial we have already learnt How to use USART module in our PIC Microcontroller and established communication between PIC and Computer. If you are an absolute beginner then check here for our all […]

A magnetic bit is being switched by bending electrons with the correct spin upwards through the bit. A special anti-ferromagnetic material on top of the bits makes the process reliable. Source: Arno van den Brink Use your computer without the need to start it up: a new type of magnetic memory makes it possible. This […]

Cree has crammed up to 2,250 lm capability into a 5x5mm LED – achieved at 19W. The LED is called XHP50, the first in a family of XHP lighting LEDs. “At its maximum current, the XHP50 provides twice the light output of the industry’s brightest single-die LED, the XM-L2 LED, at a similar lumens per […]

In Part 1 of this tutorial, we discussed about Sensirion’s SHT1x and SHT7x series of humidity sensors, their interface specifications, the communication protocol used for transferring data in and out of the sensor, and the equations to convert their digital outputs to actual physical quantities. These sensors are capable of measuring temperature along with relative […]

Tiny Bootloader This is a bootloader for the Microchip PIC microcontrollers. It is the smallest bootloader, taking less than 100 words of program space; Supports families of PIC devices: 16F, 18F, dsPIC30 (those devices that support self-programming) Does not support yet PIC24, dsPIC33, PIC18xxJyy Download Tiny PIC Bootloader   Features of the firmware Size of […]

It’s very easy! This is a simple GAL programmer that hobbyists will able to use the GAL very easy. Building costs are less than 1/10 of cheaper GAL programmers. This is good for parsonal use. And added an optional function to program to the Microchip’s PIC with using a socket converter. Programer Specifications Supported Device […]
