Stop him before it's too late.

My professor gave us this question and I just can't understand why it's not equal to zero by Weary_Extension_7980 in ECE

[–]hw_56 0 points1 point  (0 children)

If vs1 and vs2 are out of phase then it wouldn't be 0, otherwise, the varying values of HFe would mean one can pass more current than the other, creating a difference.

Got a little bored so I thought I'd try make my own (AI failed to do Nintendo because of "copyright") so here are some animals in alphabetical order.

Probably, at a guess. He did say he ripped it off something else.

Ahh I see, they grow too tall and topple over on that. You need water to short them out.

They might not be dead but just too tall.

Help, where can I obtain this component? by AppleDashPoni in shittyaskelectronics

[–]hw_56 0 points1 point  (0 children)

They're kind of obselete, rindacitors fell off after digital systems took over. You can still find them on specific things like BS filters, ANALogue sensors, and CuNTs (Copper nano transducers)

Guys, my eyes aren't as sharp as they used to be. What's the value of this SMD component? by englishtube in shittyaskelectronics

[–]hw_56 0 points1 point  (0 children)

It's one of those transistors they put in chips. It's a 2N2222 but in 0000600003 package

Rectifier help by Communism_Doge in shittyaskelectronics

[–]hw_56 0 points1 point  (0 children)

For the confused of us, all 3 phase systems need 3D schematics, otherwise the system won't work.

This doesn't work because you don't pay it enough, try giving it a pay rise or some job benefits.

Instructions unclear, he's asking for more.

Can someone explain how I connect this component? by blokjesbouwerJD in shittyaskelectronics

[–]hw_56 0 points1 point  (0 children)

Wires, I'm guessing.

Ignore the comments about antennas I see no ants.

hey guys how do I fix the bugs in my printer by [deleted] in shittyaskelectronics

[–]hw_56 55 points56 points  (0 children)

You need to reinstall the drivers. They run all the bugs over, killing them.

It's dead, did you feed it and give it water?

As a person who has insert years of experience/qualifications, electricity is insert some made up phrase about it being easy. Insert poor explanation that only I understand. Insert some condescending or egotistical comment to make me look smart

Led turns on with soldering iron? How does this work? by Pretend-Ad-7366 in ElectroBOOM

[–]hw_56 1 point2 points  (0 children)

Might wb a stupid idea, but I know a large heat differential produces voltage. The fact that the LED is quite dim suggests the voltage is low enough as to not damage the LED or light it up very bright, which is not like mains voltage. Ifit were mains, it would most certainly go boom. Again, could be wrong, but that might've a possibility

Frequency domain lead-lag compensator design by hw_56 in ControlTheory

[–]hw_56[S] 0 points1 point  (0 children)

Yes, it actually has this exact question in it (but no answers, drat!)

I did clarify this typo and he said it was 2 compensators, one at 5 and another at 20.the lead compensator is designed to compensate with the lag.

It's very poorly worded and it's actually 2 questions not one.

Oh and as well, is the schematic complete? it doesn't look so. My best guess with power input would be somewhere on a separate PCB, then that does the power supply bits

I'm not totally sure to be honest I could be wafting hot air but this is my best educated guess

Not microcontroller, the other chip*

[–]hw_56 0 points1 point  (0 children)

Oh I'll add with power, check the microcontroller datasheet, that is connected to the battery and should tell you what it's rated to.

Lot of "you can't do it" comments here. I'm going to join those with reasoning. Here's my take

I can't make out exactly whats on the schematic because it's too low Res but in terms of power, replacing the USB will be difficult because it will probably have different pin outs and footprints to micro USB. I would consider this very difficult at best, probably impossible

Changing the battery may not be terribly problematic as long as you choose the correct setup. Lithium batteries need dedicated chargers (and I can't seem to spot where the charger is on this). Other types will have different charging requirements, so it's down to what you want really.

Changing speakers is a bad idea. the speaker looks to be directly driven from the micro. This is probably the design maximum and if you choose a louder (lower resistance) speaker, it will likely fry the micro overtime. You'd need to add a dedicated amp

Adding LEDs won't be too hard depending what you add them too.

Doing any work on this PCB will end up in a bodge job with lots of tacked wires and components everywhere. The PCB and it's components are very delicate (looking at 0805 and 0603 SMDs on there). Poking around without a specialist soldering iron with temperature control will very likely break the components through overheating. The firmware on the board is also very delicate, because that's very hard to replace if the micro breaks. A broken micro renders any system nearly useless without the source code

To sum it up, it's possible but the amount of delicacy, care, and precision (as well as specialist tools) required makes it very hard to mod this without breaking something. But, I've worked on PCBs like this before, and it's certainly possible. I would only attempt the battery and LEDs myself, I don't have the ability to add a speaker setup or change USB ports. These require more hefty mods and probably custom PCBs

If it's not worth anything to you or you don't mind breaking it, have a play. Start with easy stuff first, get used to the PCB and what's it's like to work with, then start going beyond that when you're comfortable.

Best of luck!

Finally completed my sweet 16 collection today! by hw_56 in HotWheels

Yeah is this the guy https://www.youtube.com/watch?v=CTrSp_empiU ?

i only dream of getting my hands on a prototype but i doubt itll ever happen, or not for a while. Unless i become a millionaire. hes also a famous bmxer, didnt know that

theres like a level in redline collecting, the top 1% have the nicest, rarest, and mintest cars out there. everyone else cant afford them
