No easy way as of the moment. This has been a blocker for rpi_ws281x, the open source Userspace Raspberry Pi library for controlling WS281X LEDs. You can see the solution and follow the discussion here: github.com/jgarff/rpi_ws281x/issues/528

Sorry, no idea about your question related to SafePal to Binance transfer.

Yes, this drive is compatible with all T14s gen1 and T14 gen1 laptops.

You can use the open source hardware Raspberry Pi add-on board that I've designed ANAVI Gardening uHAT and the Python3 examples provided for it to build a irrigation system for your plants. Another interesting option is to integrate it with the popular open source solution Home Assistant.

@LeonAnavi thanks!

Yes, you can set up DOSBox-X with Windows 98.

@LeonAnavi would I need more than 1 MB ram

Yes, it is a mess. It is kind of an industry trend that the laptop designers follow. This year Intel launched Lunar Lake with integrated RAM within the SoC (as on-package 16GB or 32GB LPDDR5X-8533 RAM). Shortly after releasing this I read news Intel regrets doing it and won't do it for the next generation SoCs. We'll see how it goes.

Unfortunately, as far as I know you cannot purchase a replacement easily. As of the moment Renesas DA9091 is not available through popular distributors such as Mouser, Farnell or DigiKey. Eventually, you may consider desoldering DA9091 from another broken rpi5 (with other issues).

Yes! As an alternative to the webcam you can also consider using the special Raspberry Pi cameras that are attached to the CSI connector on Raspberry Pi Zero.

They have several boards for retro computing nowadays. I purchased Neo6502 but I haven't even started with it yet. Which one do you have? I feel your pain regarding shipping fees. Olimex are neighbors so I didn't have to pay high shipping fees for these boards but I know how it goes for board from other vendors...

You will need to create a Yocto/OE machine configuration for your custom board.

Yes, I have built it using Yocot/OE layers meta-freescale, meta-freescale-3rdparty and meta-freescale-distro. The machine name is olimex-imx8mp-evb and the image is core-image-weston.

Thank you sir.

It would be very helpful if you make a video of building the image for a custom board. Thank you so much for the reply and everything and for sharing your knowledge

@somashekarkiran9991 you are welcome :)

@@somashekarkiran9991 making a custom board capable of running embedded Linux and doing the hardware bring-up takes a huge amount of time and can't be fitted in a short video. Actually for this Olimex SoM I have contributed several bits upstream as part of building the image that you see in the video to meta-freescale, meta-freescale-3rdparty and the downstream Linux kernel fork linux-fslc-imx. You can have a look at my GitHub pull requests to learn more about the details: github.com/Freescale/meta-freescale/pull/2025 github.com/Freescale/linux-fslc/pull/694 github.com/Freescale/meta-freescale-3rdparty/pull/309

I am not sure it is going to work out well. These SSD1306 displays have small resolution. The one on the video is with 128x64px. Why don't you use the luma.oled Python3 library in your case?

Hm... I am not sure. It might. Probably better buy HP dock station in this case. Depends on the laptop. What HP laptop do you have?

You can check if 12V is supported by the power supply with function isVoltageDetected as part of the negotiation and implement whatever you want to do if it is not available. You can modify the demonstrate Arduino sketch as an example. It is available at GitHub.

Thank for watching the video. It seems that you are experiencing an odd issue. Did you try it on another computer? On which OS is this happening?

@LeonAnavi I didn't try in another computer, I will. My OS is Windows. Btw, my keyboard key switches are blue. Thank you anyway.

@@ppppppppyyyytoppp the color of the switches shouldn't matter in this case. Try to install the OMEN app for Windows that configures the keyboard. I am Linux guy so I haven't used it but it might help. Also when you can try the keyboard on another computer. The lights require additional power so this might be an issue in your case. Do you get any of the lights below the keys on when you plug the keyboards?

Yes, I see your point. Thinkpad P1 is definitely a power hungry beast.

Yes, I tend to use Raspberry Pi Zeros for headless low-power embedded Linux projects. It still fits really well for them. I absolutely agree that the rest of the boards with the same form factor don't invest enough in software support and because of this doesn't have a large community of users. Btw, speaking about these boards, I recently published a longer video for XPI-3566-Zero which is the same form factor as Raspberry Pi Zero but with better hardware and Rockchip RK3566.

@@LeonAnavi I'm just now getting into IoT things and am looking for some interesting ideas to do with these... and yes the idea of having a tiny linux computer I can stick anywhere opens up a world of possibilities.

@@PikesPeace-lul explore add-on boards for Raspberry Pi Zero. I have made several open source hardware uHATs for various use cases: infrared, gardening, controlling LED strips, etc.

What is your experience after switching from a Thinkpad to Dell XPS series? Some of the XPS laptops look pretty nice.

Good question. Some T490 models have "touch style fingerprint reader on palm rest, match-on-chip". It is an optional feature. I have to check if this particular unit has one.

Good point! I've just checked. The Intel firmware takes 9 seconds. The loader takes another 7 seconds, the kernel for a bit more than a second and 23 seconds for the user space. Surprise, surprise the total boot time according to systemd-analyze is 41-42 seconds (not 25sec as I said in the video). I didn't pay attention to this when preparing the video. The thing is that actually the laptop is operational in about 25 seconds and I can open a terminal but there are another 10+ seconds for GNOME desktop environment to be fully initialized.

Nice, T410 is a solid model! Are you using with a Linux distribution?

@@LeonAnavi yes since age 16 until now I'm 21

@marlenmarko77 well done! Which distro do you use on t410?

Yes, good point. Radxa ZERO 3W is similar to XPI-3566-Zero ZERO. Unfortunately I don't have it so I can't make a side by side comparison right now. Do you have experience with Radxa ZERO 3W?

Well... This is gen 1 and a few months ago gen 5 made a debut on the market.

Sure, but we are at the point where laptops are pretty serviceable for years, as long as you don't want them to be top gaming machines ;)

I agree in general. T14s in particular is not so serviceable because of the soldered RAM to the system board and the keyboard whose replacement is hard. Because of this I prefer T14.

@@RalfPinkaire-f7w cool! The AMD model must have better performance.

Thanks! According to the datasheet it is MIPI-CSI.

I asked Geniatech and they confirmed this is a MIPI-CSI interface for a camera. It is awkward but the "LCD" label on the printed circuit board is just a component identification used during manufacturing and doesn't directly indicate a display interface.

My primary laptop is Lenovo ThinkPad X1 Yoga i5-1235U. I have been using it for more than a year but it went under repair while in warranty. The process was straight-forward and the laptop was repaired in about 2-3 days. The T14s laptop from the video is from 2021 and the warranty has expired and I didn't experience any technical issues with it so far. What kind of issues do you have with your laptop?

@@LeonAnavi Have 6 Lenovo laptops. If you have bad luck and you get a defective piece and call them more than 3 times, they don't turn back. I am using 13900HX with all addon features like 32GB and 8GB graphics and so on.

Which Lenovo models do you have? Keep in mind there is a huge difference between ThinkPad and other Lenovo models. There is also difference between the ThinkPad series. I have been using the T series quite a lot through the years. I own and have experience with T460s, T480s, T490, T490s, T14 Gen 1, T14s Gen 1 and X1 Yoga i5-1235U. Only the Yoga had a hardware issue during the warranty period and it was quickly handled.

its not related to models; it's related to the service provided by Lenovo.

In which region are you? ThinkPad customer care in my region is handled by IBS Bulgaria and it was excellent. As far as I hear they provide pretty much the same good services for ThinkPad warranty repairs in the EU and the UK.

Yes, absolutely! Soldered RAM is hard to be repaired. Earlier this year Intel went a step further with integrated RAM into the Lunar Lake SoC for better performance. However, the latest headlines are saying that even Intel admits it as a mistake.

Bull. It almost never goes wrong.

I use the HDMI 1.4b port on M75q

My pleasure! I am happy to hear this short video is useful :)

ANAVI Dev Mic is available for purchase at Mouser and Crowd Supply: www.mouser.bg/ProductDetail/ANAVI-Technology/ANAVI-DEV-MIC?qs=iLKYxzqNS75%252BzWeKsr6W6Q%3D%3D

Probably ThinkPad T14 or P14s will be a better fit. They are a bit more bulky than T14s from this video but have Ethernet port and expansible RAM. Both are quite similar. P14s comes with a dedicated NVIDIA graphics card.

Good point! Thank you for mentioning it.

Which is better?

@@Blueyopo afaik in theory TLC perform better and last longer.

@@LeonAnavi thanks the info

3 EUR sounds as a bargain. Is it with the same Macrosilicon MS2109 chip? You mentioned yours is without a heatsink. Have you considered an upgrade by adding a small heatsink to protected it from over heating?

@@LeonAnavi Yes, same chip. I've bought other 2, waiting for delivery. When they arrive I'll check if they have the same missing heatsink.

@@LeonAnavi ok, just received the other two. The package is slightly different, the graphics are bigger, looks made by two different manufacture. Same main CHIP (MS2109, but different serial) but the EEPROM chip named "U7" on the board is different (the first purchase was a AT24C16, the second one is a MS24C16. Also the second bunch is glued on the case from the bottom. The board have the same version and production date (2020_07_16). Everyone without a heatsink. I was thinking to install one, but actually the product doesn't look to become that warm when in use.

Yes, you can connect a OLED 1.3" SSD1306 display with resolution 64×128 over the SPI or I2C bus on XIAO ESP32C6.

@LeonAnavi I need make holographic cube but problem was I need smaller Esp32 & 1.3 TFT display 240x240 resolution. kzbin.info/www/bejne/iIKqq2ypqqqfpZosi=TIFgz_XBhiY5xiXQ

Use the Waveshare ST7789 240x240 1.3" display: www.waveshare.com/1.3inch-lcd-module.htm

The GPIO is 3.3V tolerant. Please consider using an optocoupler if you need to read higher input voltages. I have shown how to do it for 12V or 24V in another video: kzbin.info/www/bejne/noWkh4JqqpaXZ9Usi=kx-rTGOo9E_W-I5V

I think Ducky offers this keyboard in several different colors and you can change the keycaps of the Cherry MX switches with white keycaps that you like.

Yes, you are right :) I cleaned it a bit after putting the new NVMe SSD in.

No, sorry I don't have a slower video. Please just pause or replay the part you are interested in. On 1:30 the connector on the far left is for the power supply. The Thunderbolt 4 cable connects the laptop to the dock. It goes in the 3rd connector from left to right that again can be seen at 1:30. It is marked with a label that shows a laptop and a lightning. The display ports for your monitors are in the middle. There is also an HDMI connector next to the display ports. I have two HDMI monitors: one is connected to the HDMI port and the other is connected through a Hama HDMI to display port adapter. This can be seen at 4:05.

Thanks ✌️

No, the other microUSB port (the one on the far right) is just for powering Raspberry Pi Zero 2.

Great to hear! Have you performed any other upgrades on your T490?

@LeonAnavi Not yet. I'm new to ThinkPad community. Later on I'd like to see how much memory I can upgrade, right now it has 512. And I haven't personally opened the machine, a friend of mine upgraded it for me and got it from the overseas so it was really inexpensive like less than $300. I work as a content writer so most I do is open 100s of tabs that's why I got 32 gigs. Anyway, do suggest if you have any ideas. I also use two external monitors so I'll be buying it's docking station. And oh, it's the qhd model non touch and the panel is simply amazing. I haven't used a keyboard like this one.

As you can see in the video, if you need more space the upgrade of the SSD is easy. Owning a docking station is a pretty handy. The price of the 2nd hand compatible docking stations drops rapidly for older models like this. It is good idea to buy one at a decent price. Last but not least using a Linux distribution is a game changer in terms of improved performance for T490 but of course you need to get used to Linux if you haven't used it before.

@@LeonAnavi As a matter of fact, i did install Ubuntu yesterday especially since my cousin hyped it so much. However, I don't like few things, touchpad isn't working normally, windows gestures are had to figure out and a few other things makes me really uncomfortable. I think i'll be switching back unfortunately. Thanks for the suggestion though.

What's wrong with the touchpad? Nowadays Ubuntu GUI is basically a GNOME desktop environment with some Ubuntu specific configurations. You can configure it further for your taste but yes, indeed it takes time to get used to it if you are switching from another OS and/or different desktop environment.

Raspberry Pi 5 is the first board from the family with a chip at 45-degree angle. As far as I know it has been done to simplify the wiring of the Gigabit Ethernet PHY because of the constrained space on the PCB.

Well, honestly Raspberry Pi CM4 is with quad-core 64-bit ARM SoC so it performs far better. However, STM32MP157 is very affordable chip and it is appropriate for industrial applications where high performance is not required.

@ thanks
