I heard someone might be doing a UK batch of glasgow boards?
<d1b2>
<ebb> @Attie :)

<Attie> o/
<d1b2>
<Attie> getting a bit high on numbers ... which is far past my expectations (speaks for the team's work I guess - good job!)
<d1b2>
<Attie> i'm collecting emails and countries (EU only please), and will be preparing a message to everyone who's shown interest to go out "soon"
<d1b2>
<Attie> (UK included in "EU"... groan)
<electronic_eel>
Attie: gotta make really sure to ship everything before the end of the year then...

<neverville> Is the hardware out?
<d1b2>
<ebb> In what sense?

<d1b2>
<Attie> @electronic_eel ugh, yeah... hoping it won't even be close, but you never know
<electronic_eel>
unfortunately lead times can become quite a problem once you need more than a few parts
<d1b2>
<Attie> indeed
<d1b2>
<Attie> i'm putting a stop to any more going on the list, but happy to maintain a waiting list in case we get any spares
<d1b2>
<Attie> @esden - would you mind sharing any stats on yield of revC1? if you have them to hand
<d1b2>
<Attie> I think I'm currently planning to put it to the group:
<d1b2>
<Attie> A) go with revC1, probably get boards sooner, hw exists, sw exists, but yield may be lower (driving cost up), or
<d1b2>
<Attie> B) wait for revC2 to be ready, hw hasn't been proven, sw doesn't exist, etc...
<d1b2>
<Attie> I imagine that option B is fundamentally a matter of getting boards slightly sooner than 1b2 would have them on offer, so depending on timescales it may be more sensible to just wait it out
<noopwafel>
fund the purchase of cute puppies to make excessively sad faces at esden
<d1b2>
<Attie> @esden - can you give any insight into the state / timescales on revC2? (I don't mean to add pressure / apologies)
<d1b2>
<Attie> yield on revC1 is certainly a concern - not trying to down play that at all

<tnt>
I mean "yield" is all relative, you can always rework by hand for a few boards ...

[glasgow] electroniceel opened pull request #198: applet.interface.uart: allow to invert the UART line signals (=idle low) - https://git.io/JJd99
<d1b2>
<Attie> true, ok really trying to get a feel for the risk / how many boards may be problematic
<d1b2>
<Attie> a run of ~60x isn't "small" any more (at least for me), so if we're looking at approx 10% requiring rework, that's probably manageable
<d1b2>
<Attie> If it's more like "many of these will need attention", then less so
<d1b2>
<Attie> *s/ok/I'm/
<electronic_eel>
do you have experience with managing runs this size? it will take a lot of effort, even just the taking orders, payment, packaging, shipping part
<electronic_eel>
I once did a group order for smd parts storage containers for 40 people and it was a lot more work than I anticipated
<d1b2>
<Attie> honestly, I don't (was originally expecting 10-15 boards)
<electronic_eel>
and this was just for people in Germany, since I didn't want to do international shipping. And I think that was a good choice...
<d1b2>
<Attie> I'm sure it'll be effort than I'm anticipating, but I hope I'm not being too naive
<d1b2>
<ebb> If it looks like it'll be overwhelming effort, is there any possibility of distributing the work to willing volunteers?
<tnt>
I remember that at the last ccc, pretty much all the boards needed _some_ amount of rework, but they had been partially manually placed ... so for something fully automated, I would expect much less issues. The changes aren't that big and those components/package used on the C1 are used all the time on tons of products ...
<tnt>
What's your CM ?
<d1b2>
<Attie> i have a somewhat willing live-in volunteer, and a local friend who wants a board has offered to help, so it's not just me
<d1b2>
<Attie> good to know, i'll probably use PCBWay, as they've done me well in the past for things on this sort of scale (i.e: footprint scale, not qty)
<d1b2>
<Attie> my big concerns currently are yield/rework and reading up more on shipping to the EU, though i'm sure some unknown-unknowns will come up along the way

<esden> @Attie so the campaign will be launched by the second week of next month. That is the goal now. I want to finish the prototype design this week. Got some really good progress yesterday. Will continue today.

<d1b2>
<Attie> looking forward to the campaign, and I'll be mentioning it to the group too

<Attie> @esden - as I said, I'll be mentioning your campaign to the group... so that I can set expectations: I presume you want to verify the design, it'll be starting ~4 weeks from now, running for a month, and fulfilment sometime after? So realistically boards probably won't be with people until at least 3 months from "now"... does that sound about right?
<d1b2>
<Attie> (if you'd like to keep a lid on it for now, that's fine too)
<d1b2>
<esden> Yeah that is a reasonable and probably optimistic calculation. It really depends on how popular the campaign will end up being. There are some cutoffs where you can save time because the batch is below or above a certain size.
