Re: Raspberry Pi camera from Rs components lead time ?

If I knew that there wouldn't be a long lead time , I would order from RS but now I ordered from eBay .... I hope I'll get it soon.

Re: Help with controling 4 SSRs - H E L P !!!

To control 4 of them, you would do the same for 4 different GPIO pins, and do as you posted to define "1" or "0" as their output value. Hope this points you in the right direction ^^ And how exactly i connect the ssr with the raspberry pi ?? http://i40.tinypic.com/xnhlkk.jpg which one of the two pi...

Re: Speech To Text

You could try Google's Voice API, if you want to do speech recognition when you do have internet. You can also try Pocketsphinx for offline recognition. The thing is that Pocketsphinx didn't work well for me....... For Google Speech Recognition: http://campus.albion.edu/squirrel/2012/03/01/google-sp...

Re: Good or bad psu ? help..

Does it have a fixed lead or a seperate lead with a USB socket ?. Have you measured the voltage both sides of the F3 polyfuse ?. Some Pis appear to have polyfuses that are a bit high resistance and drop the volatage quite a lot. But, if its doing the job, I'd tend to leave it alone. Some Micro USB ...

Re: Raspberry Pi doesn't stay powered up for long.

Sure. It's F3 on the opposite side from the USB power. I basically I heated the area with a heat gun moving back and forth for about 30 seconds or so. Then I let it cool for a half hour and tried again. The board is still up and running with no freezing or network drops. http://i.imgur.com/XiN8Q.jp...

Re: Raspberry Pi doesn't stay powered up for long.

Well I took the risk of using a heat gun to heat the poly fuse. Let it sit for half an hour and I'm posting this from the Pi itself. I'm going to let it run for the day to see how stable it is. So far so good. It's been stable for the past 15 minutes. :D Been running the Pi for about 3 1/2 hours no...
