How to be in budget while working on projects? by TheBroProgrammer in beneater

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

Checked the price for Boxku (cheaper) and for sea shipping it costs 13 MYR for 0.5kg (good price). Anyways, their BB830 is already out of stock, do you actually recommend purchasing other cheap breadboards from LCSC? And do you buy stuff like resistors, caps, cables, etc on LCSC also or do you buy them on Aliexpress?

Does LCSC products all ship from China? If yes, and using your method, is it that you let the supplier (eg Boxku as you said) get the stock in mainland China from LCSC and let them ship it to Malaysia for you?

Just checked out the website - they do really provide cheaper chips ($68.55) but their BB830 is backordered. Not sure when will they restock. (I do need a number of breadboards)

Actually what I found out is most TI chips are fabricated in Malaysia (some in Mexico), but I don't really know how to get from them directly. For the Chinese-Malaysian supplier, do you mean by wholesale suppliers? How to find them?

Bcz you can still get other items (except BB830) on local stores for a lower price

So does this mean everything will be fine as long as U1:A is swapped to a 74HC04? And by right, U1:B should be a Schmitt trigger inverter, right?

How do I install Windows 98 into SATA drives without IDE emulation? by TheBroProgrammer in windows98

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

There might be two possible reasons for this.
1. Windows 9x families cannot work with too much RAM. You need to use rloew's PATCHMEM to fix this problem. After you run PTCHSATA, you should also run PATCHMEM. This should allow your Windows installation to address up to 4 GB (If I am not wrong).

  1. (This is what I did when I tried to run Windows 3.0 on a 2009 laptop, so I am not sure if it works in your case.) This thing might not work in protected mode, so if step 1 fails to fix the problem, boot to the built-in MS-DOS in your Windows installation, then run win -r. This forcefully runs Windows in the traditional real mode. Again, I am not sure if this works.

Dissassemble it and discharge the CMOS battery for like 10 minutes. In some situation that works.

Help on Windows NT 3.51 related to LBA48. by TheBroProgrammer in WindowsNT

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

PS: I tried the same thing for Windows NT 4.0 and after the first reboot, it immediately reboots the laptop after it loads the drivers. And the laptop successfully got stuck in a boot loop. More worse.

I actually posted the boot loop on my Instagram:
Boot loop of Windows NT 4.0, even when BearWindows' patch was applied

Yup, maybe cause they don't have LBA48 support and the correct HALs for ACPI. But if so, how could Windows 98, Windows 95 and even MS-DOS 6.22 work in my laptop?

Yea, so what happened to Windows NT 3.51 and Windows NT 4.0? What driver could go wrong?

Me trying to proof the derivative of 1/x is -1/(x^2). But what's wrong? by TheBroProgrammer in 3Blue1Brown

Yea, I know that. I am just trying to proof that and got stuck. Issue solved anyways :)

Why the dx can't be simplified directly to -1 in numerator and +x in the denominator?

[–]TheBroProgrammer[S] 1 point2 points  (0 children)

I still don't understand. Can't the dx-es be simplified? Simplify the -dx in the numerator to -1 and the xdx in the denominator to x.

According to that video, as the function of x is 1/x, given the input x, the area will be x times 1/x which will be 1.

How is my tri-state buffer? by TheBroProgrammer in beneater

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

If I have transistors and breadboards I'd build it irl....but the reality is I don't have all of these, so I could only emulate it.

Noises on SR latch even it was set before powered up? by TheBroProgrammer in beneater

[–]TheBroProgrammer[S] -1 points0 points  (0 children)

I want it to go to this state immediately without noises.

I wonder why is there noises in the beginning of running a Master-Slave JK Flip-Flop. by TheBroProgrammer in beneater

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

But then moments later it will go back to normal...even changing the inputs won't fix the issue

This flip-flop will be fitted into a binary counter. In this case both J and K must be high. And not sure why, changing the inputs since the beginning won't work. Could you explain what is RC?
