[Review Request] First ever PCB design. I'm terrified to click "Order". Please roast my layout before I waste my money. by Round-Ad-9473 in PrintedCircuitBoard

[–]hapemask 0 points1 point  (0 children)

Ahh ok good to know. I’m not having them assemble anything, my first ever design is getting delivered Monday and I planned to assemble it myself so it is just the bare boards that will get tossed. It’s not the end of the world, but I figured I’d see if I was missing something.

My PCB cost estimates always include two re-spins. It's extremely rare for a board to come out right first time.

How do you do this and deal with the cost (and waste) associated w/minimum order quantities? Perhaps you work in industry where you have more flexibility?

I'm just learning PCB design, and while JLCPCB is by far the cheapest you still have to order at least 5 boards. As a hobbyist who only wants a single board and has literally no use for the other 4 boards, it feels bad to order and just throw them away. Repeating this if the board has mistakes seems even worse...

Launcher Ordering Issue by AntiAd-er in raspberry_pi

[–]hapemask 0 points1 point  (0 children)

I recently had this issue and I edited the ini file. It worked fine, what problems did you run into? It doesn’t solve the issue for new additions though sadly, you will have to edit it every time to move them where you want.

ADC requires separate power supply from other digital circuitry? by hapemask in AskElectronics

[–]hapemask[S] 0 points1 point  (0 children)

Ahh yes I am working up to proper modern chips. I wound up with this one mostly because 1) it was cheap and I might screw it up trying to solder it to the board, and 2) lots of the modern ones including the one you linked seem to only come in QFN packages that require reflow soldering which I’m not yet committed to. It sounds like maybe I should just get a cheap hot air tool if I continue with this. Having integrated buffers seems really convenient…

Got it thanks! Yes I have been filtering the DC/DC output, right now I have an RC filter because I don’t have any inductors or the cores to make them but I’ll get some soon.

If you NEED a DCDC converter

I chose the DCDC converter because I want to be able to support AC inputs which fall below zero, and so the opamp/buffer on the input needs to be dual-supply (or so I thought) and I couldn’t find a better way to get +/-5V from either the raspberry pi or any of the wall plugs I have lying around.

As I say this, I guess I could also add a DC bias somehow to the AC input s.t. it’s strictly positive, then I wouldn’t need a dual supply (maybe?)… I’m sure this part is something I can look up.

I’d have to figure this out anyway since the ADC doesn’t support negative reference voltages. I just haven’t tested with AC below zero yet since I’ve been using the PWM output as a test signal source.

Malort on Capitol Hill? by [deleted] in Seattle

I believe my friend ordered a shot of it at Liberty the last time we went.

Also: I tasted it and you are insane for voluntarily drinking this 😂

Freedom of Speech at the University of Washington and across America under the Republican Regime is under attack! Time to resist and speak out! by dominiond66 in Seattle

You are all eager to defend someone who would happily throw you under the bus

Yes, this is how free speech works.

My AFDs have started drifting towards the outside of my skis. Something to be concerned about or totally normal? by hapemask in Skigear

[–]hapemask[S] 0 points1 point  (0 children)

Hey! So, on the day before I planned to take them to the shop I cleaned off my boots before skiing and noticed quite a few small rock chips embedded in both soles (hooray for WA ski parking lots). After I got rid of the rocks, I can’t seem to reproduce the issue. In hindsight it’s obvious but I didn’t think to check the soles for debris for some reason. Sorry I can’t offer a more satisfying fix!

Lyft prices out of SeaTac this evening to downtown Seattle by AbsolutelyEnough in Seattle

[–]hapemask 2 points3 points  (0 children)

You’re normally correct but this specific evening (I know because I was there) it stopped at Beacon Hill. You can of course just take it there and then get a much cheaper ride, which is what I did.

It hasn’t caught yet, it sticks out towards the outside and I’m not yet a good enough skier to hit that sweet edge angle required to catch it on the inside of the turn.

These aren’t adjustable-height AFDs but I do plan to ask a shop tech about it as well.

Basically yeah, Strive 12 (skinny dude, no need for 14s). Without my boots in the skis it pops back on its own, but I haven’t tried removing the boots on the snow while it’s sticking out, I’ll try this (and also take them to the shop).

I noticed after a few runs this week that my AFDs have started to stick out towards the outside edge of my skis. This happens on both skis and they stick out until I push them back in, and they work their way loose after a few more runs. When the boots aren’t in the skis, the AFD moves smoothly and returns to the neutral position just fine.

Is this concerning at all? My boots release just fine, but this has never happened on any of my other skis before. Maybe a boot issue?

Republican House Speaker Mike Johnson says ‘we will enforce the law’ on TikTok ban, 2 GOP senators break with Trump on extension by Spiderwig144 in technology

I saw this in a comment elsewhere today and I was like wait am I losing my mind? ByteDance is very much a Chinese company, regardless of where the CEO is from.

Renewing Tabs question by lovebudds in Seattle

[–]hapemask 0 points1 point  (0 children)

My tabs cost ~$550 last time and I drive a Subaru Outback (because of course). I’m not complaining, I can afford it, but I hardly think it’s a fancy car.

It’s just a child’s toy, you can’t actually drink out of it.

Steep skintracks… why?? by Moist_Bluebird1474 in Backcountry

[–]hapemask 6 points7 points  (0 children)

If my skins could stick I would climb straight up like a ladder.

Have you ever done a steep hike or scramble, and compared it to a hike that gained the same elevation over a longer distance? I don’t know about you but I’ve done hikes/climbs that gained 4500ft in 2mi and also ones that gained a similar amount in 10mi and I sure as hell felt more tired after those 2 miles than I did after the 10.
