What to look for I bought Avnet’s $49 Spartan 3A development board but it was discontinued not long afterward – right about the time when I decided I needed a few dozen more. I’ve since done some extensive research (thanks, Google!) to find a comparable thrifty thrill. When choosing a development board, consider what you

Several of our recent projects have used a 16 bit PIC24 microcontroller from Microchip. The PIC24FJ128GC006 contains two 16-bit ADC channels which makes it useful for measuring voltages more accurately than the 10 or 12 bit ADCs you normally find on microcontrollers. We used this microcontroller for the temperature controller on our recent Soldering Robot

The solar energy collection is not that easy compared to the different types of power generation system because it has the lowest capacity factor. It has 5 out of 24 hours in a day that it can generate electricity from its solar collection. The only solution to this is by optimizing the 5 hours solar

Common-Emitter and Common-Collector Transistor Amplifier Calculator for High-frequency Operation Analysis of the bipolar transistor amplifier at low-frequency is relatively easy, and several calculators exist online that do a good job. For high-frequency operation, there are fewer references available. For my projects, I like to build a reference spreadhseet where everything is in one place. This

The ATMega168 is a great general purpose 8-bit AVR microcontroller from Atmel. It has 23 GPIO pins, but sometimes (as I have found) you can run out of I/O pins as your design grows. This happened to me recently when, of the 23 GPIO pins available, 2 were taken up by an external ceramic resonator,

An application note from Texas Instruments, white LED driver with digital and PWM brightness control (PDF!): With a 40-V rated integrated switch FET, the TPS61160/1 is a boost converter that drives LEDs in series. The boost converter runs at 600kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows for the use
