I am. VERY.
Snippets of what’s to come when I find some time:
“Mistery” circuit giveaway:
Needle printer head dismantling, because, why not?
And some more relay guts…
And I’m outta time again…!!
Hello, technicians, how are you? Fantastic!
Look at these racks:
Now back at me. Sadly, those are our racks, not yours, but if our purchasing manager had asked, instead of trying to use is half-brain, they could be as god as yours. Look down, back up, yes, you just looked at your keyboard, only $Deity knows why. (source, sort of XD!)
Finally we have racks of our own. However, we also have an imbecile* purchasing manager of our own too.
Because, you know, if you buy something for someone else, you might try asking what they need…shouldn’t you? In fact, our racks are all except the middle one, whose size we have been using for eons through our diferent assemblers. The smaller ones belong to our old (and broken) tin wave solder machine, and the new ones, those big, chunky metal…things…are the new racks our personal imbecile bought.
I should be thankful we only have one of the bigger ones, still their size and weight is enormous compared to the normal one. Damn…some days I just don’t want to wake up, just keep designing pcb’s in my dreams.
*from Classical Latin imbecilis, imbecillus, feeble, weak, probably ; from in-, without + baculus, staff (see bacillus): hence “without support”.
It’s been a while since the last time you heard about that board assembler that it’s-not-that-good-but-it’s-cheap. But when he screws-up, he does it big time, won’t fail you there. (ROFL!)
If you more or less know how Pick&Place machines work, you know they do some adjustments around for each board, so components fall where they are supposed. Sometimes you must help the machine, because the fiducials fall outside machine expectations due to weird panelizing by the board maker.
That’s a bugger, but nothing you can’t overcome, just move the camera around, find the spots and add those values to the program so the machine knows what to find…
If you happen to write down those coordinates with permanent marker…DAMN, MAN, clean them!
Cos’ you won’t be able to clean them, no matter what, once they go through the oven…
And there you go, a pair of expensive boards we can’t sell, nor clean, no nothing…
How many leds are too many?
Do you want to get a board like this for free? Of course you want. If you had to pay for it, it would be bloody damn expensive!
I have said tons of times that I have a great job, it’s time you taste some of it’s wonders too.
So I have a 5 boards like that one, and do not plan on doing anything with them, so I’d like to have some fun before letting them go. (boards run on 40V 350mA, power supply NOT included. Size: 25x25cm, free shipping within reasonable limits)
Complete as many tests as you can, be polite to strangers and don’t cheat:
Yeah, there’s mischief in there. keep yourself centered on achievable goals, and GO! GO! GO!
You have 30 days!
Unofficial presentation of the mistery circuit:
Unfortunately, I made the 0805 footprints just as large as the components themselves, so I can’t solder them by hand.
I will use 0603 instead, wich are still easily solderable, meanwhile, I really wanted to test the circuit, so quickly botched the necessary values from wherever I could:
I could order a stencil for the circuit, or cut one myself on kapton (with the laser), I just didn’t want to bother for the test, as I didn’t had all the components either. (I forgot to order some rarer components…but with 3 weeks delay between ordering and receiving…I keep loosing track of projects).
It works, whatever it is it does, since you still only suspect what it is…
Interestingly, the board fabber did say that the edges where going to be V-Scored, but the boards are nicely machined, so that’s a nice surprise to have.
By the way, I haven’t forgot about the Circuit Giveaway. Once I get the components and have some good photos of the circuit, I’ll announce the winner.
Hot air gun, copper disc for heat distribution and a thin FR4 board…what can go wrong? Especially when the heat control of said airgun is proximity adjusting to the disc with cardboard sheets.
You know, sometimes I wonder what of the things I do [like this] are a normal practice on other companies or it’s just mine (mine in the form of “whomever pays me for having fun at work“). I have coworkers that have been in bigger companies, who say this is NOT normal i so many ways, that they wonder how in hell the company still works…but also I have other friends who work in the repair industry and they tell some scary stories, but individually, they only tell one or two at most…
And my imaginary friends just, well…keep their opinions to themselves.
