So, I ordered my first Raspberry Pi today. Should arrive tomorrow. I am busy downloading the Operating System off the Raspberry site. 1Gb in size! And it's a zip file. Local suppliers didn't have the SD card with the OS already set up. This should be fun trying to get it to download and be in the correct file....

I have a request to design a commercial product and decided to jump into the deep end. I said "yes, I can do it" and will worry about the outcome at a later date.

There are plenty of tutorials available on the net so I am not looking for help.....not yet. I just wanted to see who else uses or would like to use this device. Looking at what it can do, it appears to be an extremely powerful and cost effective device.

Damn! Twice now it has aborted after about 50Mb of downloading saying there is an unexpected error. I can see the fun already beginning.

Yup, I have a Raspberry Pi 2 running Berryboot with Raspian and OpenElec.

Have you tried the torrent links for the OS?

ti haven't. I will ask my kids to help me. Much easier than learning about torrents and downloads. Unfortunately, once that is done, I have to work out the Raspberry stuff for myself.

All part of a big learning curve. I was going to say I'm too old for this but I have to plod on. Something new every day.

What do you use yours for?

If your kids know about torrenting, it'll be a doddle.

Once you've got it downloaded the tutorials on the raspberry pi website are all pretty straightforward.

Basically, I just use mine as a Kodi media player and for hacking around with linux and Python. I have it plugged into the living room TV and use this keyboard with it.

I managed to get the torrent working and unzipped to the SD card. All by myself. Will check it out tomorrow when the RPi arrives. Can't wait.

I will use Python to write the app. I have a basic idea about programming so the learning curve shouldn't be too bumpy. I write PIC assembler and PLC Ladder programs for most of my products.

That's half the battle won.

Sounds cool.

RPi 3 has wireless and bluetooth with a quadcore ARM. Sweet!

How does any LAN and USB work with Pi3? On the 2 and 1, it is my understanding that the chip has a single USB line, which is then connected to a USB hub chip, with some lines from the hub chip exposed as USB ports and one line from the hub going to an Ethernet controller. This causes problems esp if using USB such as storage and LAN at the same time (and it seemed to me that it had low throughput anyway). Does the Pi3 differ? I've also looked into the Banana Pi projects.

The Pi 3 shares the same LAN9514 chip as the Pi 2, so all the USB ports, the Ethernet are multiplexed over a single USB 2.0 channel to the SoC, as usual. However, the WiFi and Bluetooth are instead connected via the SDIO, so won't need to leech off the same bus.

I don't think we're looking at a massive performance boost in real world terms, and it's none at all if you're still using the wired Ethernet port, but there's a little bit of cunning design in there for no extra cost.

Worked first time!!!!!

Now to familiarise myself with a new system. Seems to be as easy as Pi to operate and navigate. I like what I see so far.

Good stuff!

I found a local RPi user group on Meetup. You should see if there's one in your area.

I had look but no luck. We are a bit behind this side of the world.

This message was typed on my RPi. I connected to the office wi-fi, searched for and opened RS and typed this.

I am impressed. This small device, about the size of a pack of 20's, can do so much.

I inserted a usb flash into the slot and could read all pictures. text fles and speadsheets etc easily.

I suppose I'm not used to new devices, that is why I am so impressed.

Damn! Twice now it has aborted after about 50Mb of downloading saying there is an unexpected error. I can see the fun already beginning.

the concept got off to a good start, but the arrival of cheap 1000 core GPU cards, and 30 quid 8 core tablets has altered the market somewhat.

So, I can now read a push button and turn an LED on and off. I can also retrieve a .jpg from the flash drive and display it.

Now to figure out how to configure the I2C bus. I read about there being a bug in the I2C system. Hopefully, it doesn't affect me too much. Has something to do with clock stretching. I need to daisy chain a heap of external controllers onto the system so I can read and write to remote stations.

I used to have one. I managed to install Gentoo on it and was mostly using it over SSH. The plan was to have it storing backings for my laptop and desktop. I don't have a need for that at the moment.

I can now talk to a DS1307 RTC chip via the I2C bus. What a mission! They don't tell you too much about things like that!

Eventually, with the help of 2 mods on the Raspberry Forum, I managed to get it working. One of the mods was part of the development teams and knew what he was talking about.

This Linux and Python gobbledy gook is really testing me.

Going like a Boeing!

I have attached a PIC16F884 onto the I2C bus and can now write to it from the RPi. There is now a RTC, the DS1307, and the PIC slave on at the same time. Each one can be addressed and written to. Next stage is to read from the PIC.

Small steps again.

I think you have made an error. You need the Rhubarb 2100, it's got twice the RAM and the PARP operating system which has more gusto than any ordinary raspberry.

Too late now.....there's no way I'm going through another learning curve.
