@@suspiciousstew1169 I think it's more common in rugged devices. Stuff that's meant to be used in a quarry, in the field, by surveyors, etc. are more likely to have these. I think. It used to be a big thing in more high end laptops, but now that most people can get a laptop if they want (as the cheap ones are usable), most people work in the city, every coffeeshop has free wifi and every phone can now be used as a hotspot it's far less common.

[@putraadriansyah8082]

If you're going to use a PC PSU as external power supply again in the future, try to make a USB Optocoupler to trigger the green wire so you don't need to jumper the psu with paperclip and don't need to remove it because as soon as the board powered on/off, the optocoupler will also get powered on/off, and also it will trigger the PSU on or off. Try a cheap PC817 with some resistor

[@gordslater]

When you run two PSUs, it's best practice to bond the case ground to case ground (assuming both of them have metal cases) ...AS WELL AS... the zero volt rails to each other. Keep these seperate - for example, bond the cases with one heavy ground wire. Seperately, bond both 0V rails (black wires, usually) together. In your situation here, I assume you#re using a 19V plastic brick PSU and the second PSU is the $5 metal case ATX PSU, so, being unable to bond the PSUs cases because one is plastic, you simply make sure the black wire of the second PSU is very firmly connected to the chassis 0V of the mini PC, usually the metal case is directly connected to the 0V line. I've guessing that there was a potential differance ("a voltage" to most people) between the 0V rail on one PSU and the 0V rail on the other PSU. The only thing linking the two 0V rails together was the screening earth braid on the SATA cables, so current was flowing on the SATA screen. This sort of thing can cause all sorts of wierdness. It's not so much about mains safety grouding (to anyone in the US), or "earthing" (in the traditional British English sense - electrical engineers really call that equipotential bonding of exposed metalwork. Nope, it's actually more about making sure that leakage currents or noise voltages don't affect both the devices you are powering AND the PSU regulators themselves. In simple terms: "it's f-ing complicated" :) The potential difference can easily occur do to RFI Y-capacitors on the mains input of one or both PSUs, as the caps are never perfectly equal value and also have a inherent leakage current. This is why you get a "tickle" from the DC power lead on some laptop PSUs. For years I've wondered how gamers could get away with running 2 PSUs in the same case to power a huge GPU, in reality, without bonding the 0V rails there coiuld be all sorts of unusual currents flowing across their GPU and through the PCIe (or PCI/AGP/IDE) socket in a similar way to the way your SATA lead was trying to equalize the two independetly floating 0V rails. For anyone running NAS systems with lots of disks and 2 or more PSUs, it was less of a problem back in the day because each spinning HDD had a nice fat metal case and was screwed directly to the mounting rails in a metal chassis. The HDD 0V rail was internally connected at or near the power connecter on the disk to the metal disk case via the PCB mounting screw pads. But recently, as people do this with SSD and their plastic cases, the problem is occuring on 2-PSU DIY NAS boxes too.

[@trrjecto4459]

Only for my understanding, it will be enough if I connect the PSU case to the ProDesk case? At the PSU a screw at the mounting bracket with a wire and then the attach somewhere at the ProDesk case, like a case screw?

I was recently working on an HP SFF pc that only had 2 sata ports, one was in use for the DVD drive and one for the internal hard drive. We added a 2.5" SSD to it but there was no extra sata port. I found on Amazon you can get a little adapter that is the same size as a wifi card that has 2x SATA ports on it so I put that in there and connected the DVD drive to the expansion board and put the SSD into the motherboard. Works awesome. The PC is used on Ethernet so didn't need wifi (and the slot actually came empty on this model of SFF PC!)

Just a tip: Limine boot loader can help to tie together two completely different operating systems together that want to be the only OS on your system, like Windows and Linux (or FreeBSD). Not super plug and play, as there's no default config file and documentation is fairly thin, but it's super doable to glue virtually anything together with Limine (within reason) and have it stick. I've been dual booting with it between different machines and OS for about a year now, and it's been rock solid.

Curiously not all of these slots were created equally.

Got a HP 800 G4 mini, a newer model that the one showed in the video. Did and experiment with one of those E-key 2.5 gigabit ethernet cards, great fun. Managed to snag an actual Intel-based card (i225) for pretty cheap and mounted it in the G4. Was a tight fit for the E-key card, then the actual Ethernet port (the dangly end like shown in the video) had to be fastened somehow. I managed to get it securely mounted INSIDE the G4 by first of all insulating the metal on it with electrical tape (important), then I used those plastic-coated metal wires you get from packages (I always save those, good to have) and tied the Ethernet port down. There are multiple holes on the back of the PC where you could fasten such wires. The card works great and the port sits flush with the back of the PC.

Is the external antenna required for wifi? The wifi card doesn't have signal?

[@gustersongusterson4120]

Peter's video was really cool to come across! I appeciate the run though of all these devices, thanks.

[@DigitalTalon]

Watching the video and it's clear you've never experienced the thrill of running 2 PCUs together! 😂😂 Reminds me of the good ol' days when I first started mining; we had to make sure they were properly earthed together. Ah, the memories! ⚡

I've found the slot useful for non wifi, much like you. With the Dell MFF PC's they have Realtek NIC's onboard. Which suck as vmware ESX 7 or later doesn't support them. Rather than have USB adatpers hanging out, put in an Intel 210 gigabit NIC in to slot. The older dell MFF PC's have a VGA hole, which nicely takes the RJ45 connector. It looks almost factory fit. Vmware 7 or 8 will then install. Once vmware is running, you can pass the onboard Realtek NIC through to an OS to use natively if you want. Is how I did my openense firewall - use the Realtek NIC as the external interface, and use the Intel as the internal bridge, alongside other VMs. I don't have an overly quick internet connection, so not an issue for me with regards to the internal NIC contention

for me the coolest thing i found was esim or lte or whatever adapter

[@Myself-yh9rr]

I hear on the ones with a "whitelist" the computer will just show an error message and not boot. I also heard that they have been stopping that. It is no guarantee that you don't have a whitelist restricted computer. I think the main reason they did do it at all was to keep someone from using WiFi cards intended for other countries that don't meet or follow all of the FCC regulations. When it comes to these things it is amazing all of the things the manufacturers must do to avoid upsetting the FCC (or similar organization where you might live).

I recently installed the coral dual TPU in my wifi slot, however, it did not work at all. The bios picked it up as a GND device, but it does not show up under the PCIe devices on Linux. I have an "asrock z690m-itx/ax" motherboard, which according to the specifications supports: "type 2230 WiFi/BT PCIe WiFi module and Intel® CNVi (Integrated WiFi/BT)". So if you see this, be aware!

I was recently looking for something to use the Wi-Fi socket on a Fujitsu FUTRO-S920 and found a M.2 NGFF to PCI-E Adapter Card to accept an NVMe, which is a nice boost to the mSATA that it came with.

[@brajanubgan88]

About the 2x sata, if you're going to use 2.5 drives you can wire them to the usb ports for power It may not be the most elegant solution, but it should work as long as they don't require 12v I recommend grabbing molex to sata adapters, cutting the molex socket along with 12v cables and wire it up to an old, broken usb cord, that way you can easily replace it, extend it or do whatever you want with it

[@gordslater]

My own experience is that 2.5 inch HDDs (both spinning and SSD) need only 5V In theory, 3.3V may be required for some disks, but I haven't seen one in the wild. 3.5 inch HDDs require both 12V and 5V though.

[@rexsceleratorum1632]

That is exactly how I powered the boot SSD of my previous server

[@ALittleBitOfEverything-wd9ee]

​@@rexsceleratorum1632 That's both very clever and sort of scary if it was a production server in a business environment. I think that I can learn from you. Do you have a channel or website?

[@ALittleBitOfEverything-wd9ee]

​@@gordslaterIn my ignorance, does modern USB but not version 4 / Thunderbolt have sufficient amperage to power high capacity drives? I know that the new standards designed to be able to charge a laptop can handle up to about 100 watts, and I dimly recall USB 1.0 being specified for enough wattage that it could handle things like adapters for serial and other legacy ports (plus the standard was designed to allow up to 127 or 128 connected devices) but I thought that the generations between 1 and 3.something were fairly minimal amperage? Hence why when I plug my smartphone into the USB 2 port it says "charging slowly" instead of the fast charge I get with a 2.3 amp wall adapter. But I am aware that I could be confused about all of this, and I have not ever really needed to investigate HD or SSD power draws. Thank you very much.

[@rexsceleratorum1632]

@@ALittleBitOfEverything-wd9ee Nothing so dramatic, just my home server in the form of an old laptop (hardware and electricity being expensive by Indian standards). I wanted to attach a few SSD's to it (for RAID) using various shenanigans involving mini-pcie to sata adapters and even a micro-sata to sata cable that I soldered together. I don't have a channel, I'm really bad at documenting things.

[@Raintiger88]

A few months ago, I bought several B, M, A, E , B+M and A+E and maybe B+E key adaptors (they are packed away) for testing on a latte panda delta 3 and one other MB that I just can't recall at the moment. This was a bit of a flashback to some of the headaches I had while attempting this. I'm reasonably certain that many of my problems were related to the BIOS. Not sure if the devices were whitelisted/blocked in the BIOS or how/why an engineer would even go through the trouble to block and/or enable only certain things, but I do recall having issues getting them to work properly. Adding to the frustration was the fact that BIOS (for the most part) is still secret sauce stuff and I just don't know how they limit and/or allow just certain PCIe devices (or any other device). I can only say that I eventually gave up. I really wish I could have found a completely open BIOS that I could have flashed that would just simply treat any PCIe device as something communicating on the PCIe bus - but that doesn't seem to be the case. Before I ever do this again, I want to find a completely open BIOS that I can configure and flash at will. It really shouldn't be that difficult.

[@ALittleBitOfEverything-wd9ee]

Did you have these experiences using the LattePanda, the other motherboard, or both? And if you don't mind sharing, what are your other experiences with the LattePanda Delta? I am on a tight budget right now, so I am considering getting one of their new Sigma series with the 32 GB of RAM now available and using it both as my main computer for a while and to learn Arduino.

[@Raintiger88]

The only thing I did last year was pull it out of the box and power it up to make sure it was working as expected. I think it has win11 on it and the arduino software in right on the desktop.. I think it's a really cool product and I don't regret buying it. I just don't have the time to learn arduino right now.@@ALittleBitOfEverything-wd9ee

Those Coral modules are UNOBTAINIUM at any reasonable price or without exorbitant shipping fees!

[@charleshines2142]

I heard that they used to whitelist like that but don't really any more. I heard HP was one of them that used to do it. I had a more modern HP laptop from the last couple years and upgraded its WiFi myself. I used an AX200NGW and that is even though it wasn't listed as one of the cards that the laptop could have came with if it was a model based off the same motherboard. I just had to get another antenna for it. It only had the cable for one antenna. I just stuck it down somewhere inside the case, it seems asenine to make us mess with the display bezels and do all of that work to get to it. I just made sure to put it where it will not short something. I also taped down the small bit of excess cable but never sharply bent it anywhere. I just needed it to stay in place so it won't move and get pinched when I close it again. I have a new roll of 3M electrical tape for that. The new card worked, none of the computer refusing to boot with it or any of that

For AI in an M.2 A+E-key 2230 slot, look at the Hailo-8. No affiliation, I just like it better than Coral.

before the russian/ukraine war i got a PCI adapter to use the Dual TPU over a normal PCI slot. works great in my server with Frigate..

I’m fairly certain that the mini PCIe slot can be used to add GPUs to mini machines that have no other PCI slots

If you decide you want to do the 2.5gbe in one of those hp mini's let me know Ill print and send you a couple adapters so the port isnt just hanging out the back.

You can power 2.5" drives on a mini pc without an external psu by taking 5v from usb ports. It's very easy to hack a cable by cutting and old usb cable and joining it to a sata power connector from an old psu.

[@marcg1043]

Great inspiration...liked the 2.5G NIC atapter idea. SATA drives not realy practical because those SFF boxes dont offer enough power to run HDs anyway....But still thanks for another great video. For 2.5G is a 2.5G switch sufficient or don't you also need to add a special 2.5G router?

[@LazyBunnyKiera]

They make an E-key to PCIe adapter, similar to m.2 m-key to PCIe for egpus. It can support 2 lanes of pcie, usually 3.0. I had an old laptop i wanted to get it for, but the adapter was too expensive for what it was. 2 lanes of pcie gen3 would be fine for something like a gtx 1050. I wish my current laptop uses an e-key slot for it's wifi, but instead the wifi is soldered on. If it had an e-key, i could use a pcie wifi card, AND still tap into the usb lines to install some internal USB devices.
