Spent this Labor Day Weekend on a number of projects around the house but still had some time to undertake a couple of simple electronics projects.
The first project was to bread board a simple 5V regulated power supply using parts from Radio Shack and schematics from a couple of helpful websites found via Google.
The end result was a hybrid using the diagram below from http://www.tkk.fi/Misc/Electronics/circuits/psu_5v.html
and the schematic below from the Sparkfun Embeded Electronics Tutorial at http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=57
My design didn’t include the diode or the switch as the Sparkfun design does but did include the 0.1uF capacitor and the LED/resistor. The Sparkfun tutorial also included a diagram of the pinout for the 7805.
The second project was to assemble the Sparkfun Breadboard Power Supply 5V/3.3V (Part No: PRT-00114) http://www.sparkfun.com/commerce/product_info.php?products_id=114 which arrived during the week.
The assembly was a breeze and took less than an hour.
A word of thanks to the folks at Sparkfun for all the good information on their website, the wonderful products they make available and for the speed with which they get things out the door. I have now ordered from them twice and both times have used the USPS Priority shipping option and gotten my order the in three days of placing it.
