Does it say anywhere on your website what has changed between the different revisions and also what revision you're currently on?
I saw somewhere someone posted they had a NFC S4-mini v5 - is v5 the most current one? And how do we know what changed from v4?
I think that person who posted that was mixing it up with an NCASE M1, which is currently on V5. For as long as I've been following the S4 (which to be honest wasn't long at all, probably 6 - 7 months), I only know of two versions. I'll let Josh chime in to either confirm/deny/or add to my description. The only changes in the current version are:
1) The cases are no longer powdercoated. It's expensive and harder to get near perfect results. However, Josh has said that he will do some small limited edition runs in powder when he finds a color he likes. Obviously these will also be more expensive than the standard models.
2) The mounting holes for the DC power jack hole has been elongated to allow the use of an HDPLEX DC-IN as well as other panel mount DC jacks without modifications.
3) A Kensington Lock slot was added to the top of the case which also attaches to the inner chassis as well.
@MrNintend0 I am currently running the SF600 externally with no issues. However, i did cheat and just jump the ground to PS_ON at the psu. I just recently decided that I was going to try making a custom cable harness for it that only carries enough 12V/Ground/and the PS_ON line to the pico so that I can get the PSU to turn on and off with the computer. However, when I did a preliminary test, the PSU would only click on then off when I pushed my power button on the PC.
All I did was take a wire and shove it in the PS_ON pin of the pico (on the 160XT it is pretty accessible) and connect it to the PS_ON on the PSU. I am guessing that there is a sense wire or something that I am missing? However, the PSU turns on just fine if I jump PS_ON directly to ground. Any idea what I'm missing here?
*EDIT1* Never mind, I think I was looking at the 24 pin from the wrong side >.<
*EDIT2* Tried the "correct" pin and the PSU doesn't do anything
If all goes well, then I should hopefully have one 16/3 or maybe 14/3 cable going from my PSU to the S4. I plan on using a 6 pin mini-fit jr connector at the S4 case since I am having trouble finding a decent DC power connector that will handle 15 amps that will look okay. From there, power can go straight to my 1060 SC without having to go to the pico first since the PSU will not always be on. That will eliminate having to go all the way to the pico and then back. I will obviously still need to run 12V and ground to the pico for the motherboard power and possible peripherals.
I believe the reason why it didn't work is because the Pico wasn't getting power in the first place... yet. When you hit the power button on a PC, it sends a signal to the motherboard to ground the PS_ON wire, which tells the PSU to send power to the rest of the system. With your setup, the problem is that while you also had it connected to the SF600, the Pico didn't have access to any power (no power from the SF600 yet), therefore the system could not start before the Pico could be fully "charged" (voltage rise) from the SF600.
To simplify it:the power switch tells the Pico and SF600 to start. The SF600 was already "primed" and lets the power flow to the Pico. The Pico, which is supplying the heart of the system with power, isn't "primed" yet. Therefore, the PC doesn't have power to use and cannot start, so it cancels the PS_ON signal, which in turn turns both PSU's off.
Note that this is only theory. I have very, very basic electronics knowledge (enough to have some common sense, but no real "intelligence"), so someone correct me if I'm wrong please.
If you're using the SF600 as a replacement for the power brick, you'll need to ground the PS_ON wire before you can push the power button on the PC for the Pico. The cheapest way would be just using a short jumper wire. The best way would be wiring a small SPST toggle switch to the wires, then if you really wanted, put the switch in an easy to access location near the S4.
Anyways, remember that the Mini-Fit Jr. pins are rated at 9 Amps per pin, which leads us to 108 Watts per pair of 12V+ and Ground pins.
