content: Bwahaha, just opened a customer's existing design and saw these.There is some sense of humor still around after all!Tim

content: Ahah. Humor or too much time to waste...Incidentally, since the "teepee" kind of looks like it's floating above its connection point, it may actually mislead you into thinking that its galvanically isolated.Humor is not always an engineer's best friend.Not sure what the "5000" means either.

content: Quote from: SiliconWizard on October 29, 2018, 07:13:46 pmKeystone makes a bunch of test points numbered in the 5000s. Their products are almost all numbered, which makes them kind of annoying to search for, but Digikey at least seems to usually get the idea.Tim

content: does anyone else think that doing that at work is opening yourself up to some crap from other people when someones decides its time to sacrifice someone to resolve a problem? unless you work in a utopia I would recommend against this.

Hey look on the bright side, I watch alot of animal planet, my views of corporate function must be a bit skewed. Can't help bringing buffaloes and camouflage to mind though. Not everyone works for WY though

content: Quote from: coppercone2 on October 29, 2018, 09:00:08 pmLike 50% of my time is spent faffing around tweaking traces and wringing my hands over those ugly routes that inevitably make dog legs no matter how I try to place the components...I'd go nuts if I couldn't waste time doing stuff like this...Role model disclaimer: I work quickly, apparently even with faffing about twice as fast as the average person (and with fewer mistakes -- one upside to faffing, it's inspection, ah, yeah, inspection, let's go with that). I don't recommend changing your behavior to replicate mine, if you don't have the experience, comfort with tools, and neuroticism I do.Tim

content: In my early years, I was an IBM assembler programmer. Label names were limited to 8 characters which encouraged cryptic rather than descriptive ones. I had to make a change to a program that had some rather unimaginative label names: AIN, BIN, CIN, etc. in one routine; AOX, BOX, COX etc. in another. The change I had to make was in this latter routine and I needed to add a new label - so in the midst of GOX, HOX and others, I added FOXINSOX.Gave me a smile for a day. You have to havesomefun.

content: Quote from: coppercone2 on October 29, 2018, 09:00:08 pmI'm not saying that what you describe might not happen, but to live your whole life defending against this sort of possibility seems more miserable than getting fired by the sort of people that would actually do this. I mean, if I heard that someone got fired for a reason like this, I wouldn't want to work at that company much longer anyway so being the one to be fired is frankly killing two birds with one stone.

content: Quote from: Brumby on October 30, 2018, 04:42:40 amThe concept of this thread, and you mentioning IBM, reminds me of another story.IBM often calls their computer systems by certain numbers.There was an old valve/tube computer, called the 709.So when that very same computer was converted to be transistorized. They originally tried to call it the 709T(709-T).Because, T for Transistor.The way 709T sounds in English, and because of the expectation of all digit IBM computer names.Many people thought and called the 709T, a 7090, for hopefully obvious reasons.So they (IBM) gave up, and officially called it the 7090.https://en.wikipedia.org/wiki/IBM_7090

content: Quote from: MK14 on October 30, 2018, 05:01:18 amOk, that triggered a story of my own, once while reviewing resume's for a new teammate at a former employer I came across someone who said they'd worked with "Cisco 20950" switches, which was enough to indicate they never had. Those devices were actually 2950's, but if you'd only ever heard the name and never actually seen or managed one, it's easy to be confused hearing "twenty-nine fifty"

content: I dunno about this one.Seems to me that the whole point about a test point is to have access. So tenting it kinda defies that purpose.

content: Sometimes you have to do something for your sanity. At an intern job, which was largely make work, we had to create sketches of the work to be performed at different job sites. They had to have an orientation arrow on them and the interns competed for the fanciest North arrow. Some were really ornate. All done with India ink on vellum paper.This same instinct obviously existed for Medieval manuscript copiers. And now their work is displayed in museums. I am pretty sure that our North arrows will never see this response, but I do regret that I don't have some copies. Of course using the ammonia copiers of the day that would have been painful. And would have faded to nothing by now.

content: I often put little Easter eggs on PCBs, usually under a IC but yesterday I stuck one on an inner layer near the fiducial. I hope that when held upto the light I can see it. It's the little things that can get you through a long day. I'll post a pic when it comes back.

content: I don't do that because you can get a bad rev or some kind of stupid problem and then it just looks bad. If its something you missed that someone realizes at first glance and you have some kinda artistic expression going on the PCB people might get pissed. Especially if its one of those 'if I only spent 20 seconds more re-reading the data sheet for the 15th time' things. Of course no one gives a shit about your sanity and they want to find blame for why the prototype needs more engineering time.Try arguing for your sake when there is a closed door meeting going on where you are not present and it comes up..
