Re: Does anyone know technology for the PI to help people read?

I do not know if it'll have what you are looking for. This is a good lost of education software, it is linked to from debianEdu (education oriented debian distribution) http://www.skolelinux.no/linux-signpost/showUserMenu.php You'll probably need to install, see if it works and try it out.

Re: New AWB algorithm in test firmware

I've not use the camera much, but do have the v1 of both types
Unfortunately I can't send them back up in the rocket for a while,.so will have to be normal testing.

I'm assuming if I use picamera python module, it'll just work?

Sorry, I got the wrong end of the stick, I thought you were trying to poll faster than it would allow, and/or worry about the heating effect at 1second polling.

It's a simple cheap device, design for background room reading I think, so not really a fast changeable device by its target. . If you take it apart you'll find it a simple thermistor and a layed humidity capturing 'square' that are converted into a digital format to make it easier to get a reliable...

Re: A Final Fibonacci Challenge

I was just looking and it seems math, numpy, scipy don't have one (even if something uses it in scipy).
I guess people just don't use it.
There are however a million different ways to do it, if they can do 1million digits or not is another matter.
Probably something for stackexchange.

It felt thin, flexible polythene so went it the landfil bin for us, as usual. Most thin wrappers cannot be recycled (and our county has the highest rate and easy recycling)

GPIO.setmode(GPIO.BCM)
Is just saying which pin naming scheme to use, if I remember correctly


SenseHAT, it uses a LPS25H (pressure/temp) and HTS221 (humid/temp) over i2c.
There is no DHT11.
