ttfx, what do you think so far.
My personal way would be to either buy the official Pi3 kit as it looks nice as a present and will work*
Or buy a Pi3 & the official PSU. Spend the money on the official one as it will work and has a nice long lead and no usb cable to faff around with.
If you know a bit about computers and use Windows/Mac
Buy a nice SD card 16 or 32GB
Samsung Evo Plus do very well here and are not overly expensive.
And you can easily put NOOBS on with etcher** (edit see below for correction, minor error by me, you just copy it across following the instructions on the main site)
Buy a HDMI cable, longish so it'll reach the TV easily if that is what you'll be using.
Get a nice keyboard and mouse. Logitech MK270 kit is a nice one, a bit smaller mouse than normal so comfy with smaller hands too.
It's £20 or less, it's wireless and it works.
No wires to worry about and getting in the way or restricting where you sit.
Not sure what Jason is on about with fsk and wpa blah blah, they will not even touch that in a normal setup.
/Me with a 9 and 12 year old using Pi since your younger than that.
Any Code Club/Jam person will know they will be fine at whatever they are given in front of them.in Raspbian.
The hard part is interest and stuff for them to do.
*I don't like the fact the keyboard/mouse are wired and do they provide a UK keyboard for us in the UK yet?
**NOOBS as then they can follow some 'install and setup' . Makes them feel that wasn't too bad and a sense of achievement.
Also an easy way to wipe and reset if thing get messed up, they are kids
Look at PINN for an alternative too.
