I agree. Do you notice that the Electronics section is so small now. All they really sell is cell (mobile) phones and low end RC cars. It is pitiful.

Re: Pi on / off PSU relay switch

@redhawk is it possible to supply a breadboard version (image) or fritzing image? I am a noob to EE and reading schematics. My first attempt was a flop.
Thanks

Hi All, As my addition to the Pi grows, I am very quickly out growing Radio Shack to buy my electronic parts. Where is a good reputable website to buy Transistors, usb micro connectors etc.. I have bought from SparkFun and Adafruit but they a geared toward the DYI crowd (which is great), but I would...

Re: Using the Pi to replicate the Budweiser Hockey Goal Ligh

Yes its possible. Python is a powerful language. There are modules/libraries that can parse XML and RSS feeds. I would start like so: learn how to write a Python program that will consume the RSS feed and Save the score. If the score changes, then send a GPIO pin high to a simple LED with a pull dow...

Re: Connection between Pi and PIC

Hi, I would suggest some reading. I bought this book in December and it covers the basics including using the GPIO pins. From there you need to read how to program micro controlors and pics (not in the book). I would suggest starting with an Arduino and learn that as well. Then you can start to lear...

Re: Pi on / off PSU relay switch

hi, I have a similar circuit that is a bit simplified with a 5vdc relay, 1N4001 diode and an ATTiny85 chip (running arduino code). I have a prototype working but I am new to electronics and my schematic is horrible :P.

Default GPIO output

Hi, If nothing is hooked up to a GPIO pin, does the OS read it as HIGH or LOW. I am trying to run a python script to shut down the Pi safely when a GPIO is set to high. With no GPIO pins connected, pin 2 is reading HIGH. Is this the normal behavior? import RPi.GPIO as GPIO import time import os GPIO...

Re: MAME Button Circuit

Your first circuit looks fine. I would suggest the following; only using a 1k pull-up resistor. Someone may correct me if I'm wrong. 1k is plenty. Also I would wire up your controls on a breadboard using some micro switches first. If all goes well start to plan the actual control PCB.
