Had 10 of these made. One is for me, the other 9 are available (won't be built until the end of the month) at cost: £20 with 2nd class postage. Ping me if you want one and I'll set it aside.
(10 built and soldered bulk plus post=£148, 10 connectors=£16, plus packaging and postage - ie. I'm not trying to sell them but to share the cost of building one…if you follow!)
