Title: Raspberry Pi
Post by: Windpower on August 28, 2014, 04:00:40 AM
I am typing this using my new Raspberry Pi using Midori browser

it is about 2" X 3" and has stereo and and HDMI outputs and 4 USB ports

$39.95 plus some cables, USB keyboard, and an old TV

it works great !

it did take about an hour to set it up (I could do it in about half that time now that I have done it once)

most of that time is sitting waiting for the Linux operating system to boot up the first time

now it boots up in less than a minute

I plugged in a USB WiFi and was into our internet hot spot

A fun new toy

nice. 

I also have been playing with pi.  I discovered retroPie, which is a distribution to be ran on a raspberry pi and has a ton of legacy gaming emulators.  nintendo, super nintendo, atari, nintendo 64, etc..  by going to google and getting roms, I have a cool little box that has about 9000 video games.  nice toy for under 50 bucks.

I had vague notions last year about using one of these as a pump controller / timer.

It does seem well suited to games ..... but it is a not-bad little computer on its own with good video and audio

I think the Arduinos would make a better pump controller, a Uno or even an Adafruit trinket would do it -- you can probably even find some code for it on-line  at github or Ardiuno  at

I did have one problem after I installed the WiFI USB (notorious power users)

The system slowed down and when I double clicked the WiFi config multiple windows of WiFi config would open until it eventually locked up

I thought --OK it ain't perfect

Then I read up on Adafruit and they strongly recommended a separate power supply (not the USB from a computer) because of the voltage drop that is typical of computer USB's and long cables -- not uncommon to get down to 4V4 -- right at the edge of the Pi's requirements

So since I had a new wall-wart regulated 5V supply made by Adafruit for Pi's that is regulated to 5.25 VDC, I tried it and viola --everything worked as advertised

Oh well back to the barn shop project.......

this may be adaptable for your pump controller idea
