Re: Best way to control LED's, sound (and video) simultaneou

I have been playing with the Pi and LED's I am experimenting with an Adafruit LED BiColour Backpack using i2c. Look at Adafruit tutorials. Just a suggestion.

Re: Gertduino for sale. £8 + [email protected]

I supplied the Gertduino with the Blinky Larson Scanner program installed.
First thing to do is read any FAQ's and disable safe boot mode on your Pi. And then follow Gordon's help at

Re: RTC

I am moving on with this complex setup issue for now. I have programmed for use, the M48P chip as a RTC clock. With Gordons instructions. For use by the Raspberry Pi. But have decided to abandon the Gertduino. For a more normal solution with a real DS1307 RTC and not the emulated DS1374 . For my rem...

Re: RTC

So. What is the real time clock on the Gertduino good for? A watchdog and or wake up system, but not keeping the Pi's clock up to date after power downs? I am obviously confused. Not all Pi's are connected to the internet and an NTP server for some applications, so I guess I'm asking can the RTC on...

Will we ever get true graphic acceleration on the Raspberry Pi?

Re: BMP085 - how to set altitude?

With any barometric altimeter you can only read pressure OR altitude you can't read both. The pressure reading assumes you're at mean sea level (MSL) If you know an accurate MSL (aka QNH) pressure value, you can fine tune your altitude value. If your location is above sea level then you need to fin...

Re: Scratch Piface 8 channel Relay

I feel the PiFace has been launched and up to now ignored. The latest instructions for PiFace does not install the latest interface without reading and installing the script manually. I did that an ended up with the latest PiFace Icon on the Raspberry Pi Xwindow desktop.

Woah. This may seem a simple thing with the Pi,s processing power. But commercial ECM's for cars are a hardened technology. Cars are a noisy environment electrically and mechanically. Also commercial ECM's comply with the CANBUS standard. Getting an ECM - Engine Control Module wrong could be disastr...

The best way to go is with stacked photo diodes, to count many more cosmic gamma ray events, and also measure their mass. Cosmic or gamma rays are damaging to human cells if they hit them.

I had the waterfalls running. But the Pi would lock up if tasked too much. I also tried monitoring Airnav frequencies in the 1090 Mhz band, so called secondary radar. This worked well. But the PI was struggling.
