Strange behaviour of Rpi pin12

I have designed a PCB that uses most of the Rpi 2 pins. On my PCB, I have physical pin 12 connected to an LED. The problem is when I try to turn the LED on, it only goes on for less than a second before turning off again. All my other pins that is also simple I/O behaves as expected. It just this da...

Re: using wiringPi and PiAUISuit in raspberry with VisualGDB

I've never used PiAUISuite and QT before but I've used VisualGDB and WiringPi a bit. I'm a big fan of VisualGDB and in my experience you pretty much can import any C++ that can cross compile under GCC into your VisualGDB projects. So I think up to that point you should be able to get things working ...

Re: surveillance system

Why not use wireless 433 Mhz PIR and magnetic door sensor? I recently experimented a bit interfacing to cheap ones that i bought on Aliexpress for about $6 and they work really well. The cool thing is that the range is quite good. I could pick them up almost right through my house. If want go this r...

Re: raspi 2 and ws2812 - printerstatus

Good luck with this. I recently finished a product called EasyPeasy ( https://www.indiegogo.com/projects/easypeasy ) where I also tried to use a Neopixel. I worked fine on my RPi B+, but I simply could not get it to work on the RPi 2. I ended up wasting a huge amount of time and eventually had to re...

Re: DS18B20 Temperature Sensing

Did you use the same resistor on both? I also had cases where the RPi would not detect the sensor until I reboot or change the resistor value etc, and I found that when I used a slightly smaller resistor it worked fine. I also recently went through all the same pains while I implemented my EasyPeasy...

Re: RPi2 433 mhz receiver

Hmmm.... This receiver is actually not too bad. Yes, there is a lot of noise while there is no signal, but as soon as a signal comes in it decodes it just fine. All these reciever modules do this, but it still works and from my experiments with it I was able to get reasonable range from it (pretty m...

Re: Raspberry Pi based Text to Speech device

Thanks for your feedback. The main purpose of this project was to give someone using a small micro like Arduino or PIC and easy way to generate short voice sentences and sound effects. I chose WAV as the file type since its widely known. This was the best way I could achieve my goal as I'm not a spe...

Raspberry Pi based Text to Speech device

I just posted my first Raspberry Pi based Kickstarter project. It's a serially controlled text to speech device and WAV file player. It would be interesting to see how the market would react to such a do-it-yourself project based on Raspberry Pi. If you have a chance, please check it out on https://...

Re: Which language to use?

I was also considering this very same question recently. For me the alternatives was mainly these: 1. .NET using Mono. This looked attractive since my normal preferred programming language is C#. However I got the impression there is not a lot of folks unsing it and I was worried about getting good ...
