Wow - about 45 minutes to compile the plan9 kernel on an original Raspberry Pi.

Thank you, Alex Fantastic Video!

is it compatible with Raspberry Pi 5?

Hi, I just came across your web site and youtube channel. Everything looks dead, what happened?

Any suggestions for which power bank would be sufficient for the Pi?

9:41 if it were me, I would have used the google lens app that automatically translates what you point the phone's camera at

Thanks for sharing, Alex! I discovered another video recently where the chap used a spiral point tap (otherwise known as a gun nose tap) as opposed to the spiral flute tap you used. It pushes the swarf out ahead of it, so really better for through holes (such as the ones you did). I tried it out, and it really works wonders! So mu better than the standard 4-flute tap, which leaves "crunchies" inside the hole and leaves a very rough thread. Try one, and you will not be disappointed! They are also much stronger, so can be used in steel without fear of breaking. Cheers!

Hello, is it possible to get the code to test my PI3, i think some of my GPIOs are out of order...

WOW ! THAT WAS HELL... SIMPLE. NOW I HAVE A PLAN AFTER MY LAPTOP DEATH.

It's a shame they chose elegance over stability. The data ports (whether on alt data or pogo pins) fail utterly with the slightest bit of interference... Like, any electronics in the vicinity, or USB devices plugged in. A true shame. With this design, it needs shielding to function properly with any reliability. Highest fail rate of any USB hubs I've tried.

hi I am trying to control steper motor with microstep driver by pwm. RPM of the motor depends on the frequency so higher frequency mean higher RPM. When i tried 1000hz my osciloscope mesured 880hz, when i tried 2000hz osciloscope mesured 1580hz and when i tried 3000hz osciloscope mesured only 2130hz. Can someone explain why?

Couldn't you use a rubber band to hold the pieces in place? Keeping it straight up and down!

I have a number of leftover screens like N133HSE, B156HAN02, etc; and I see a number of their driver boards sold at AliExpress. What I don't see, though, is a mounting case with a stand to house the resulting solution. Are these on sale, or should they be done by every DIY enthusiast individually ?

could you plis put the code in the coments section ?

how to connect raspberry pi with driver?

I always like the smell of the fluxed solder, but it's the lead fumes that are the problem with leaded solder - avoiding the neurological damage exacerbated by breathing in the fumes is the main issue. But I have to agree that lead-free solder is a right pain to use. Nice instructions in the video, though 👍

Excellent video. Thanks for taking the time to make it. FYI, a little flux will make this a whole lot easier.

I bought this one

Aint Gonna Lie Thats awesome

Brilliant, witty pi is a must have with every pi

Can witty pi work with other raspberry pi form factor and same gpio setup boards?

I have a board hooked up to the screen from my old toshiba laptop and it works fine but I have to start up the Pi to a tv screen first and then switch it over to the stand alone laptop screen from my old laptop. The screen stays blank and says no signal until I start it up to the tv and then switch it. What do I have to do to just start it up to my old screen? Thanks in advance, Mike

Great video, Thanks. I got a board from ebay and the screen comes up in Chinese so I have to figure that out from your directions. My problem is the Pi400 does not display on the screen unless I start it up to my tv screen and the switch the hdmi plug back to this screen from the tv I had it hooked up to. Any idea what the problem is? Thanks, Mike

Can this be run straight from Debian command line? I don’t have the GUI installed as running lite version of Linux. Thanks.

Thanks for the video. Now I know how to make my lcd screen work with my laptop project

Interesting but only tests output! what about the input(s)?

Do you think the threads in acrylic will last long if you screw and unscrew often with a metal screw in it? thanks!

Thank you, for this gr8 video ! Would it make any sense do connect both the ceramic and the external antenna by just adding a blob of solder to the external connector ?

Sure beats using a pocket knife!!

How abt reverse, the screen to be many pi + screen then = alot of camera?

I got resistance drift on each resistor, anyone know why this happening?

What about heat? Is the board getting hot over time?

The same chip does not necessarily mean the same sound. In my experience, the most important factor is not the DAC itself, but the noise coming into the DAC over the power lines. If you feed the DAC directly from the same power supply that is used for the CPU, then you usually end up with a lot of digital background noise, which significantly hurts the signal-to-noise ratio. Additionally, if the user lowers the volume by -12 dB (for example in KODI), then the background noise can render the audio unusable. Keep this in mind the next time you are testing another converter. Wack up your amplifier volume, play some quiet sounds and listen to the noise floor / distortion etc.

but no one has issues with tapping through a thin piece of acrylic even with regular taps. the problem is when you try to tap through the side of a 1/2-inch plexiglass without going all the way through. then that son of a gun cracks everywhere...

Awesome video. Very helpful! God bless. Always remember that Jesus Christ loves you all so much! Jesus Christ forgives all sins. Jesus Christ is God, Savior, and King!

Can you use the laptop keyboard and trackpad too? as Bluetooth or wired?

Just a little question. You said you had two laptops die from overheating. How is that possible? Laptops throttle when they get too hot, and shut down when necessary way before any real damage is done. How did the defects show themselves? I mean absolutely no respect with this, I just work in IT for a few years and never heard of a laptop that "died from overheating". Now I'm a little bit concerned about my daily driver as that little 14" dwarf isn't exactly running cold either.

Just wow!

Hi any chance that there’s a usable driver board already in the donor laptop? Thanks

Thanks for sharing your testing :)

What goes inside APA?

Could you show an example of running some of these commands from python. Great video.

Amazing. Thank you!

How come your not answering all of the questions here?

Too costly. Use a better dsi LCD from mobile market, that berry lcd has extra converter board

I wish you had used circuit board holders. Your fingers were too close to the soldering iron.

Just watch last 1 min

did first one about 6 yrs ago , have a few more now ,,I have a 2 that are old 22" all-in-one Dell computer lcd's , they are one day going to be Magic Mirror's , any luck !
