Just a quick update : made the PCB. Only 1 unrouted wire left (as always), but I'll fix that in no time this time :D New PC arrived (I'ts a laptop, I've never had a laptop!) and I'm excited because it is even faster than my old overclocked i7. Also the oven has been sent by the seller yesterday, so I'll expect it to arrive today or tomorrow. I have two syringes (extra small ones, about 2 grams [fraction of ounce - how much is the ounce btw?], only for tests) of soldering paste, so I'm ready. I bought both leaded and unleaded, because I don't know if the oven will manage to heat to 250°C although it is advertised as so (unleaded paste requires higher temp).
