Home Pi-Server Issues.

Our print server has recently died, forcing us to consider a new method of using the printer. I decided to (as quick as reasonably possible) to install CUPS on my existing VPN server to create a printer server and it all went well so I decided to create a new box specifically for it, but with a few ...

Re: Easy Arduino - Raspberry Pi serial over GPIO

The Pi TX to arduino RX circuit is best being replaced by just a wire. The emitter base voltage drop means that the arduino will only be receiving a voltage of 3.3 - 0.7 = 2.6 V for a logic one. That will not be very reliable. You must have misread, it's 5 - 0.7 = 4.3V recieved by the Ardiuino RX p...

Re: Easy Arduino - Raspberry Pi serial over GPIO

And tie the ground of the Arduino to the ground of the Pi, otherwise it won't work! I was wondering about that. Didn't think it would be so simple! :? Yes, it is that simple. If you think of a transistor or mosfet, you would normally tie the grounds together there too. Needed to complete the circui...

Re: Easy Arduino - Raspberry Pi serial over GPIO

Hang on - in the example scetch did you mean Serial.begin("9600"); or Serial.begin('115200'); ?? I'm just wondering, as the baud rates should be the same, at least I think... Thanks, Angus. If you red through more carefully I tell you to quote out the lines containing 115200. These lines would prov...

Re: Easy Arduino - Raspberry Pi serial over GPIO

I just wanted to leave a quick additional note... This was purely designed for level shifting, it was not an intention to conenct the arduino to the GPIO serial port for programming. Two things prevent this... 1) The Arduino IDE currently won't recognise the internal serial port, at all, this may ch...

Easy Arduino - Raspberry Pi serial over GPIO

I created really simple level shifter for connecting a Raspberry PI GPIO Serial (pins 6 & 8) to the Arduino serial pins (0 & 1) using transistors (I didn't have a level shifting IC to hand. https://pbs.twimg.com/media/A7g86KCCQAAgwds.jpg You don't technically need to raise the Pi TX to 5V (for the A...

Re: LapDock/RP USB power issues.

I've been using my RasPi with my lapdock for a little over a week and have not had any real apreciable power issues the whole time (I did have a mechanical issue with Micro USB connector on lapdock, but removing the "I've got a case on my phone" plate and filing down edge of my connector works perfe...

Re: Making FPC (Free Pascal) play nice with Scite

I added the Error Code reporting as an after thought and didn't test it. Naturally I wasn't paying attention and did it wrong (it was reporting error code of the echo blank line above it). Here's the fixed code, it functions the same as the old code, even with the blank line. #!/bin/bash "$1" echo -...

Making FPC (Free Pascal) play nice with Scite

I've been using Scite for quite a while as my prefered highlighting editor in Linux. But it's always had trouble playing nice with Free Pascal / Lazurus due to the pascal.properties file being intended for KDE (an issue I previously encountered with Lubuntu). It took me a wee while to figure this ou...

Re: Should have gone to...

You know... I put the guts of a homemade Playstation Lightgun pedal into one of those cases, but mine was a D&A one! And it was awesome for Time Crisis.

Re: Case design FAIL

Oh, don't get me wrong... I meant no offense. I am atrocious at 3D design, so to me it's amazing that, anyone can make, anything. I just thought it was kinda funny (more funny peculiar than funny haha). He's updated it now anyhow. Any case I make for my rPi will likely be akin to the 99p store box m...

Case design FAIL

I found a case design on Instructables.com which is a major oooops moment for whoever designed it. Particularly when you consider they're trying to sell it on Shapeways.com also. http://www.instructables.com/id/Custard-Case/#step1 http://www.shapeways.com/model/523600/custard-case-for-raspberry-pi.h...
