Minty JDM PIC Programmer using PIC18F4550 microcontroller
Minty JDM PIC Programmer This project details how to build a JDM style programmer to program PIC Microcontrollers using Microchip’s ICSP (In Circuit Serial Programming) and freeware software (PICPgm). Total project cost: less than $10. This device has been tested on both the PIC16F877 and PIC18F4550. Check the PICPgm website to see compatibility with other

I2C keypad using PIC18F4550 microcontroller
I2C keypad This instructable explains how to interface with a 4×4 keypad over an I2C bus. I started this project because I wanted some plug and play input and output modules for easy and fast prototyping of my electronics projects (mostly with PIC microcontrollers). Of course you can use leds and dip switches but they require lots

Sheffield firm slashes LED thermal resistance
Finding a way to deposit vertical dielectric barriers has allowed Litecool of Sheffield to make dramatic cut in LED thermal resistance – from 1.25 to 0.5°C/W is one case – see diagram. Dielectric layers are essential to separate electrical conductors but, with a few notable exceptions like diamond, introduce thermal barriers. Spreading heat before it

Howto Measure RTD (Resistance Temperature Detectors) over long distances
There is a multitude of process parameters nowadays that need to be measured in the industrial environment (temperature, pressure, humidity, force etc.). Out of these, undoubtedly the most common one is temperature, as it influences most manufacturing parameters. It is no wonder then that many solutions have been developed over time to measure it. There
