The Story of a Board One of the many problems I had making
PCBs with EagleCAD
was — well, complete ignorance in all things, but especially price.
I
had no idea what these things cost. So now I will share my pitiful
experience. ... This was a 4-layer 5.7“ width x 6.5” height
board; the inner layers were VCC, ground. The
Eagle count.ulp “user language program” said: AAPCB quoted $2,200; Sunstone $554.30 + their associate Screaming Circuit assembly $550 ==> $1200 or so. These are ridiculously approximate numbers and probably totally unfair, since the engineer in charge was obviously on drugs (me) — and anyway some other circuit won’t have the components, layout, etc. I had. However, it is an actual dollar amount. I’m pretty sure you are seeing it here first. ... I certainly googled a lot.... Idiotically I was surprised how costly the assembly was, but of course there is labor there. In AAPCB’s case, a bright woman or a really bright robot with whom I had 2 or three email exchanges relating to my parts list. The Sunstone/Screaming Circuits combination wasn’t nearly as impressive but, of course, they came in $1K cheaper. Two points:
And that’s all I know ... and more. ... After chickening out, I learned in a few weeks that my EagleCAD design was indeed defective in various embarrassing ways: most notably, I had set the traces to 6 mils, when a more average 10 mils would’ve done fine. ... Indeed once I started poking around, I discovered there was enough room so I could autoroute a 2-layer board without any stinking inner layers, with 10 mil traces. ... I guess I got natural talent.... MoneyI never wanted to make PCBs in my bathtub or hand-solder SMDs with mysterious hidden super-powers or reflow PCBs in my toaster oven. ... I just wanted to use a nice hi-tech tool where I could draw my schematic and magically produce assembled boards. I can sort-of do that, but (1.) it costs more than I expected and (2.) there’re still numerous areas for error, even if the circuit is more-or-less correct. The two issues relate: I wouldn’t mind so much making a few broken cheap boards. But it’s too much money to spend just to find-out I’m an idiot and shouldn’t’ve done 6 mil traces. ... What I really want is a service that will take a month or so, be of course ridiculously cheap because of that, and tell me I don’t need 6 mil traces. ... I am not holding my breath.... Iteadstudio and the Little BoardBut behold, at last, I exhale, and my PCB experiences come to a glorious lifetime conclusion for about $30 / a dozen little 2-sided boards / 30 days, at Iteadstudio. ... See my pitiful triumph in my resume.... —

Don’t Buy a Mini!!!?Before we stroll down memory lane, I must note that the minis you can buy today (Wed 4/1/15) from the kind beneficent Apple have soldered-in RAM. The only excuse for buying one of these things in the past was that the RAM was user-upgradeable. It isn’t anymore. Apple of course charges unconscionable amounts for RAM “upgrades”, but when one could buy them from one’s local internet low-price dealer, it was OK. It is no longer. The rest of the Apple computers are exorbitantly over-priced and unupgradeable — ’cause Apple designs ’em so good of course.... ~$800 2018 Model’s got Upgradeable RAM?Supposedly. Of course for $800 you can buy a pretty good real PC.

2014 iMacbook Pro Laptop (before the imini extinction event)My associate fled to the mac after being repelled by Windows 8. But now it is mine, since it was fled in its turn, to the welcoming arms of Windows 8 again & touch. ... Such are the unfathomable tides of users’ incoherent desires.... USB Ethernet FeatureSo I’ve encountered a heartwarming example of the finest customer extortion — for the rest of us. ... Apparently older Mac operating systems — I kind-of get the feeling the common folk don’t upgrade their mac software, which is the kind of thing “the rest of us” don’t do — these less-advanced macs will tolerate the odd USB-ethernet adapter from several manufacturers. ... But the Mac pro, at least updated to 10.17 or whatever it is, will not. It turns its digital nose up at those lower-class things that “just work” on the degraded and loathsome Windows, and I will get a $30 unit from Apple instead; what do I want with one of these common $10 jobbies I have littering the house?! Why the up-to-date change? Could it have anything to do with these newer macs coming entirely without an ethernet port? Or maybe — gasp! — monetization?!? ... That is, the previous Apple machines had built-in ethernet — even my imini — and the pitiful users only got the USB things for an extra port, or to fix an old mac weary in the saddle whose ethernet had sprung a leak. ... But once you flog machines that feature no ethernet — why it’s time to make ’em pay! ... Or maybe it’s just the people left supporting the Macs — i.e. after the cream is skimmed for the ithings — are so incompetent they can’t do anything else ... take your pick. ... Whatever; it’s a stirring business. ... But the panting slashdot is booming subscription Windows, so maybe usux’ll catch up.... Wireless Internet for None of Us ... or, how it would pretend to connect to the wireless, complain about “no internet”, and refuse to let me enter the passwordYes it just doesn’t work! It’s amazing! ... I still have no idea how to fix it, except in my case my Belkin wireless apparently provides a “5Ghz” version of the wireless server or whatever it is, which the svelte new iMacbook could “see”, unlike all my other machines including the imini, and for that it would ask me for the password like a decent little automaton. Which I gave it and then it worked. I suspect without the slightest basis that it somehow remembered the previous user’s acquaintance with the Belkin wireless network — buried in the hardware somewhere somehow — and that made it cranky. ... That is, incompetence.... And of course my Macs Won’t Talk to Each Other!Yes indeedy. I could see everything on either mac from my nasty low-life Windows (7) machines; but I couldn’t see either Mac — the imini or iMacbook pro — from the other. ... It really is “for the rest of us”. ... Oops I foolishly clicked “Notes” on the task bar — trying to get to text editor foolish child — and the screen’s turned green and the task bar’s disappeared. But it comes back after a minute or two. Really sharp stuff for the rest of us. ... Well I found it, but I can’t save the file anywhere but in the cloud — Apple’s iCloud jihad. ... Ah sweet tyranny. ... So the green screen seems to be here for the duration. Probably just the cheap s--t hardware falling apart. And the dock disappearance? Probably a feature; I “hid” it and it wouldn’t show but then after about a minute it would. So I “unhid” it and made it smaller. Let’s reboot. ... I mean Windows is junk too, but it’s familiar junk. ... Well screen’s still green; maybe it always was? At least it will be forever after now apparently. ... So after the reboot, a cute little TextEditor icon was stuck in the middle of the screen; I suppose I could’ve left it there and wonderful GUI windows covered it up. ... Ahhh! See the desktop picture — the stupid ocean wave — is green at the top. But the green somehow leaked onto the top-of-screen menu bar; that’s what changed. Changing the desktop picture, even back to the stupid ocean, fixed it. Oh Oh it’s probably the unspeakably wonderful transparency feature, which I may’ve turned-off in the maelstrom. ... Take that low-quality Windows! Your desktop pictures don’t so-cleverly infect adjoining graphic elements. ... Well actually I always defeat the cute transparency dumb junk in Windows — which, to its credit, provided an “old-fashioned crude XP-style turn-off cute shimmering features you dumb techno-peasant” mode.... So I will cast off this earthly Macintosh prison — and I upgraded both of the things to the grand rapturous Yosemite. I’m sure they’ll work perfectly then. ... Well actually they did. Possibly “sharing” random folders helped, but surely I did that before? ... Oh well I was able to transfer whole directories from one Mac to another. But they wouldn’t backup/copy to my real Windows systems via my fiendish batch files until I invoked the sovereign cure I’ve read so much about in the Mac magazines, “repair permissions”. Yes it cures warts and straightens legs ladies ’n’ gennlemen, without a trace! ... It’s just like my Windows cacls command, except it does ’em all at once and takes much longer.... —
the ever-cranky programmer 10/8/18: Bedtime for MacintoshIt’s been awake too long. ... Apple’s continuing efforts in aid of glorious planned obsolescence with operating system updates have been poorly-received, and after all the victim user doesn’t have to update. So one of the alternative Apple strategeries is the bulging battery: all my phones got it, as is well known by now, including the destructive fixes to slow it down by 80% or so. ... And now I can whirl my 2014 macbook pro (actually “about apple” says “late 2013”) around in the evenings; the little feet don’t touch the table anymore. ... So cute! 11/9/18: Compulsory Update in MacWin 10?It updated itself! Or last I looked, it’s trying. It was dark and still in the glad morning, so I unplugged the power and the USB and poked at it and eventually it did the Apple logo crawl ever so slowly. ... So, despite my jejeune pitiful fairies-in-the-garden-like delusions, the update is compulsory! ... I am pressing my pitiful aged fingers to my forehead — who does that remind me of?!?!? ... Thinking ... thinking ... thinking. ... Oh!!!! Could it be that other victimize-the-customer at-any-cost murican monopoly!?!?!? To which Apple is so surpassingly superior? ... But Lo! The silly machine eventually started-up and wasn’t updated! ... It went through all the hieratic gestures and sacred rituals of updating, but didn’t! ... Perhaps it’s a cunning psychological torture to force us poor sheep to do the upgrade already. Or perhaps it’s like the imini, its last senility-throes before the darkness. ... Maybe I left it on too long? How the macintoshers used to jape and gape about how dangerous it was to leave a windows machine on, but perhaps it’s got some kind of monopoly fungus? Perhaps I’ll start turning it off/on again. I was putting it into sleep mode by closing the lid because that was easiest; and that’s probably what the power button does anyway this week (no), but I will try. And look forward to failure. ... I only keep the machine alive so if I have a vague whimsical question about “what a Mac does” in such-and-such a case, I can actually find out — there is, of course, no other way, not for any machine in the universe, because all techy talk has become sacred secret omerta. ... Don’t wanna blow the gaffe to the users, do we? Turning OffThe info embargo includes turning the the stupid mac off, which the web assumes is done — get this puerile cluelessness — by pressing the power button! ... But I will blow the gaffe: control+power button, and then Enter, assuming “shutdown” is selected, else I’d have to click “shutdown”. And when it starts up again, it takes a really long time with the slow progress bar, just like cruddy windows, and perhaps that’s what I thought was it installing the TradeConspiracy update. Or perhaps it’s just headed for the planned obsolescence extinction event? ... And oh yes, the totally-optional “Mojave” TradeConspiracy update is announced in a modal dialog — what stays on top of anything else I might want to do, however unlikely, on the computer, and there’s no “X” or even the traditional scammy “later” button, so I can’t click it off. I think clicking its “info” button and clicking-off the result does it for now, but I was busy figuring-out how to power off the machine.... And in the dawdling days turning the silly thing explicitly off was too boring, so now I just close the lid and to make it sleep, as of yore, and I’ll see what it does in its impotent fury....
