Sorry if this has already been asked and answered - the IOTA threads are pretty long and there are at least 3 of them (4 threads, actually, but the fourth one is is too unofficial and reminds me a battlefield, so I discard it

).
I am one of those nasty guys who bought IOTA, but didn't connect on Ryver to participate. No time was available unfortunately. Sure, shame on me and all that...

Anyway, I read lately someone run the IOTA client on the Intel Edison device, and this somehow triggered by curiosity towards IOTA software...
Here comes the question: is there a source code to look at and experiment a little (github..?), and how I can get it together with some instructions (howto) to play a bit with IOTA (in testnet sure) on my OrangePI (btw, it is tested on ARM devices)?
I know someone will immediately redirect me to Ryver... Please do not do that - I am not going to connect there. I just hate all the additional communication media. Forum and emails is well enough for me, and even that I feel is sometime too much for me. And BTW, Ryver GUI is very resource-hungry. I use 5 different devices to connect to Internet, and some of them just cannot handle the load created by its UI.
So is it possible to publish some technical details (source, instructions) here on the forum (preferably in the OP)?
