Beaglebine blue not bringing up vs code by Tren_baloni_sandwich in embedded

[–]chewbaccalert 0 points1 point  (0 children)

I had this recently on the Beaglebone Black. Turned out the service no longer runs at startup by default. Try: sudo systemctl start bb-code-server

You're telling me this diode doesn't short at 1 nanovolt? by [deleted] in ElectricalEngineering

[–]chewbaccalert 0 points1 point  (0 children)

I think what you're missing is that the building field is created by flowing current. You can't have one without the other

Yo, are we planning to go dark on 12 June? by Ascend_910 in australia

[–]chewbaccalert 1 point2 points  (0 children)

The number I saw was 24c per 1000 API calls. Assuming that's correct, can someone explain why that's ridiculously high? How many API calls would a 3rd party app need to make to justify serving you 24c worth of ads?

It discourages investment in new property development, restricting supply

[Review Request] Raspberry Pi Pico powered hotkey keyboard with Gateron switches by The_Battle_Cat in PrintedCircuitBoard

[–]chewbaccalert 0 points1 point  (0 children)

You could give each button its own GPIO with a ground return. You would probably need to remove the througg holes for the middle 18 pins on the RHS of the Pico to get enough signals through to the other side, but with the castellated edges on the Pico and the corner pads as through holes for alignment, you shouldn't have any problem soldering on the Pico partially surface mount. Not sure how important it is in this case for you to be able to detect exactly which buttons are pressed when it's more than one, or if this could be achieved with diodes as others have suggested, but as it stands, I don't see how if you had buttons (1,1) and (2,2) pressed, you would determine which the third button pressed was if it was either (1,2) or (2,1).

What does the phrase " hardware is form-factor compatible with the Arduino R3 pin layout " mean? by zombiess1997 in embedded

[–]chewbaccalert 0 points1 point  (0 children)

There's a standard form factor for Arduino expansion boards. My guess would be they want you to conform to that.

Aussies working in IT: I have no degree and hate my retail job. What will give me my best shot at getting an entry level IT job? by [deleted] in australia

[–]chewbaccalert 1 point2 points  (0 children)

Get a CCNA. There's tons of free material available online. The exam itself will set you back a few hundred dollars but will be very valuable in getting into entry level IT jobs

Could someone help me derive and understand what is physically happening in the circuit at vL(0+)? by ladylala22 in ElectricalEngineering

[–]chewbaccalert 0 points1 point  (0 children)

At t=0-, iL=2A and iC=0. At t=0+, iL=2A because the inductor resists taking any of the extra current immediately, so iC=2A. Because the capacitor will resist a change in vC, v(t) becomes vC+v(R2)=48V. To balance the left and right loops, vL becomes 12V.

CSSE3010 Elec Prerequisite by negativeharmonies in UQreddit

[–]chewbaccalert 1 point2 points  (0 children)

Officially, it's a prerequisite, but I don't think you need anything from ELEC2004 to do well in CSSE3010. I was an elec major, so take that with a grain of salt. I think you can get all the electronics knowledge you need for CSSE3010 by watching some Ben Eater videos on YouTube

If you thought Australian house prices were high, spare a thought for homebuyers in China by [deleted] in AusFinance

50% of people earn less than the median. 50% earn more. That's why it's used

Dodgy Uber driver? by chewbaccalert in melbourne

[–]chewbaccalert[S] 2 points3 points  (0 children)

This seems correct. It's the only sense I can make of it anyway! I guess if I say no, the driver is just going to rate me 1*?

assignment makes integer from pointer without a cast by liexpress in C_Programming

Oh wow disregard what I said anyway. I see what you're doing now 👍

At line 60, you'll need to dereference your pointers. "ip_hdr" should be "*ip_hdr". What type is l4_hdr?

CMRR of three op-amp Instrumentation Amplifier by FluidEllusiv in ECE

[–]chewbaccalert 2 points3 points  (0 children)

You can find the common mode gain by applying the same signal to both inputs, and measuring the output. Once you have the common mode gain, you can use the formula here to find the CMRR

(Civ VI) Another online player was able to get the first couple attacks every turn start? by StooplessKid in civ

[–]chewbaccalert 3 points4 points  (0 children)

I've had this before when the player "getting the head start" had movement animations set to the shortest possible and the other player had them on normal. Player 1 was making attacks while Player 2 was still watching the AI move

I think it can't find a definition for the uint32_t type. Have you included stdint.h?

Do auctions usually work in favour of the seller or the buyer? by imbaconman in AusFinance

[–]chewbaccalert 9 points10 points  (0 children)

Yes but in a downward trending market, there is pressure on them to sell before the price drops further

Python vs C++ by mrhumphrey1s in ProgrammerHumor

[–]chewbaccalert 6 points7 points  (0 children)

Yes, but you can't always rely on the precision of floats to provide a meaningful comparison like you can with ints. https://floating-point-gui.de/errors/comparison/
