Remember the weblog post about mains voltage and my plan to work on some circuits involving high voltage?
Well, with fear and trepidation I can announce that the missing link has finally arrived:
That’s an “Aardlekschakelaar” in Dutch, i.e. a Residual-current device.
People are probably either very thankful or very afraid of this thing, judging by the number of acronyms under which it is known: RCD, RCCD, RCCB, GFCI, GFI, or ALCI – take your pick!
An RCD continuously compares the current in with the current out, and breaks the circuit once the difference exceeds a certain threshold. I decided to get the most sensitive one I could find, which trips at 10 mA. I’m terrified of electric shock – especially the non-lethal kind… (no idea about the other variant, and I intend to keep it that way).
Ok, so it took over a month from ordering the RCD to getting it delivered – from a mail-order company here in the Netherlands, go figure. I’ll build the RCD into my super-duper isolation jig as soon as I find some time. I sure don’t want to fiddle with 230V while distracted or in a hurry.
Speaking of which…
There are a large number of people waiting for orders from the JeeLabs shop right now, for which I offer my sincere apologies. The reason is not really lack of time (well, maybe a little…), but the fact that stocks have run out on several items. I’ve got just about everything that’s missing on order right now, but in some cases my hands are tied because things don’t always arrive as quickly as promised or expected.
I’ve been refraining from sending out partial shipments, because it doesn’t really make much sense most of the time (sending out a JeeNode without the matching JeeLink, for example), and because it adds substantially to my overhead. Which is of course my own concern, but it also raises the chance of mistakes, something which I really want to avoid.
Not everything is in yet, but I hope to have just about all shipments ready by this weekend. Please get in touch if you’d rather have a partial shipment sent out soon, rather than waiting until next week. There will be no extra charges for such split shipments.
Crazy times around here. And the long-overdue server migration isn’t making it any easier!
P.S. Don’t get me wrong. I’m still working on quite a bit of fun stuff on the side, so let me finish this slightly panicky post with a little smiley anyway :)
