A few updates :
A write up for the August tech jam can be found here *. It was a good jam, a few new people and we also managed to help some other visitors too. Physical computing activities going well as well as a useful talk on c++ by Phil Gardner.
My Raspberry Pi 3 is now running Debian 9 (Stretch). After the update scratch 2.0 is now working properly. A few new packages come with the new Raspbian, including Thonny IDE (for python). Scratch 2.0 also has some extra blocks included for more GPIO and I think Sense Hat integration.
The next Tech jam is Saturday August 9th. Plans are work in progress but can be found here *. But we will have more c++, more physical computing and perhaps some Python for beginners. I also found the resources for MinecraftPi so will try and make those available to visitors.
*Link may break after the Tech jam moves over to a new website.
