Incredible build! It looks very similar to a USB power supply I designed a couple of years ago but never ended up finishing. I used a standard Mean Well 24V power supply, an INA139 for current measurement, and an RP2040 to drive a small OLED. I had 10 output modules, each with a SW3518 for 1x USB-A and 1x USB-C. The modules connected to the main board with a 0.1 inch header and communicated over I2C. You've done a much better job than I would have done, the PCBs look beautiful!
There's another version of this project spanned over a few videos, and it has some nice piano music instead of a voice over. I'd say if the author simply put the same piano music on this video it would be best.
@@komplikatorful I just hate ALL AI voices. More realistic AI voices are even worse in many ways, because they are in the uncanny valley. It's like listening to a simulacrum of a human being, with nothing behind it.
@@user-qh7xv2bg2v Yeah, for me it is also much worse to have an AI voice than let's say a music. It's because *all* AI voices are shit - some more, some (slightly) less. Same goes for AI avatars. I end up not listening/watching the video and instead my focus is drawn to the slight imperfections and errors the AI does. I really hate it, social media is full of this and when I hear that AI voice, I automatically click dislike & move on. Honestly I would not mind paypaling @MrNDIY $50 or so - so he can buy a microphone on amazon and try to do some voicover if he wanted to really improve his videos 💪 It may not enough to buy the very best one, but it should be enough to get something that is at least good enough 🙂
All device should support such an analyse BY LAW. This is mandatory. Few questions: How much is the cost over all for this project ? Should you sale your device, would you pout a price tag on it ? There are few different issue you are solving while displaying this type of analyse: one of them is your description of how the display is working. It helps an eternal newbie to understand how this display interface with the rest. As you probably know, the value whole over is greater than the addition of all it's part. I'm a french speaker, and would display your work if your AI voice could speak the langage. Enabling your work to get in touch of more people in the large french community world wide.
Great work! Make a video of the plexi design and contruction please. Also I believe it would be smart to make a smaller version with only one pd3.1 and one 5v4a and a small oled.
@@MrNDIY-iu6ym I do not think so. I am a nerd and I like your videos, and I am sure there's more. You can extent your social media platform to facebook. You can make reels on Facebook, Instagram, Tiktok (Highly Recommended). But, do not upload the whole video so that they will get excited on your results.
Lovely PCBs and thanks for the intro to the IP6557! I would make a couple of changes though. I'd just connect the bulk 24v through the mounting posts for the PCB rather than those fragile and expensive board-to-board connectors. With gold plated contact pads and brass posts, good contact should be achieved at this relatively high voltage. The other thing is I'd use 12v bulk power which should be fine as you have buck/boost converters for the PD voltages. That way you can use a low cost high power computer power supply and you'd have 5v as well as 12v available at high currents so the 5v outputs could maybe just be an efuse. Finally, I'd use I2C rather than the somewhat outdated RS485. Over these short distances I2C would be fine, but if you wanted something more robust, CAN would be a more up to date choice.
Good idea. But I think there are two issues that need to be careful. 12V is converted to 20V or 28V, which makes the input current of the BOOST converter very large. I am not sure whether the IP6557 can work well in this mode. I2C can replace RS485. In fact, I originally planned to design an I2C interface instead of RS485. But designing an I2C slave device on STM32 has some challenges. I worried about its stability and abandoned this solution.
If you can make each port have a retractable cable, or even half the ports, I would buy one no question. If I can drop the wall charger blocks AND stop looking for cables 10 times a day... It would literally pay for itself in saved distractions. Probably weekly for me hahaha
im curious, since you chose not to build the device in such a way where you can't use every module at full load, did you build in any sort of protection/warning for this? or will the device just trip off when drawing to much current?
No need to trip. Whether it is AC/DC or DC/DC, the output is pulled down when there is overcurrent. It will not cause damage to itself or the electrical equipment.
Sorry, but this design is wrong from the beginning to the end. It looks fancy and nerdy, but that's all, it's much more designed to wow effect at some makers con than being a useful device. 1. Buck/boost converters are complicated. WHY it utilizes a 24V bus in situation you need 28V on the output? Using 30V+ you end up with simple buck converter. 2. Why every output board contains its own MCU? You can put I²C A/D converter on it. 3. Why there is not low voltage bus to power all that MCUs? 4. RS-485 is another horrible idea, it's asynchronous serial protocol, which means every MCU connected through this requires relatively precise timing (xtal). Using serial synchronous bus does not require this. 5. Why there is so many voltage references? One precise reference could be distributed across all that boards. 6. Why there are DIP switches? This could be easily negotiated through the connector between the main board and the output board? 7. Why the hell that thing runs linux just to show output voltage and current? Now I've reached the point where all that previous issues start making their weird and ugly sense. Using linux with some python (or even much worse) shit is much easier than learning how to code. This thing supports some serial async interfaces, but it lacks support for I²C and similar things. This is just perfect example how to not design electronics, because, in real world, things should be simple to manufacture and cost efficient, which this definitely is not. This is made to wow effect similar to impress weird people. I've seen similar things in the past like opamps made using tubes only just to „achieve specific sound“ or alarm clock made using NAND 7400 logic only, now I've seen this nonsense and I am almost sure there are much more to come, but I somehow feel I can't take no more, I am completely disgusted. It's your money and your time, I don't care. If this is what you want, then, ok, go for it, but there is a lot of great things outside this weird social bubble. They are complicated, they are hard to do, they are definitely not inclusive, but they are REAL. You have potential, but you are wasting it just to impress some weird people inside relatively small social bubble.
Thank you. Your suggestions are obviously quite professional and mostly feasible. But unfortunately, you confuse "consumer products" with "DIY". For a product design, cost, development time, stability, and benefits are the most important factors to consider. But for "DIY", what I am good at, what I am not good at, what I have, what I don't have, what makes me feel happy in the design process, and what makes me feel boring, this is the most important. If you look at it from the perspective of product design, this DIY has no meaning. It is expensive, has poor stability, and the ultimate goal is just to power some small devices. So from this perspective, there is no need to discuss the details, because it has not reached that step at all. From the initial demand, it is a worthless thing. But for DIY, the situation is completely different. I use my knowledge to realize my ideas, and I enjoy it, which is the most important. I can use RS485 to transmit a limited number of bytes of information, or I can use GTH in FPGA to transmit these bytes of information at a rate of up to 10Gbps. The key is which one I am good at and which one I hope for, rather than which one is the most cost-effective and which one is the best in the eyes of "others". There are many people on youtube who have such ideas, but due to limited knowledge, they often have no way to realize these ideas. I make similar equipment to make myself happy, and make videos to make people with similar ideas happy. Some people who are ready to make things by themselves may get some inspiration. You can't think that others are wasting their time just because you don't like such videos or productions. For example, you spend dozens of minutes browsing this video, or other youtube videos, just to complete a certain "work" or "task"? I don't think so. Some of those videos make you feel happy, while others make you feel disgusted. This is the emotional value, which is an important part of DIY, and sometimes, the most important one.

Yes, I've seen some similar designs and they are very interesting.

The readout is SWEET but it serves no purpose above a power strip+chargers and charge analyzer from aliexpress.

OpenWRT. I buy a development kit and it contains a openwrt firmwire. I didn't change this option.
