Ah yes, december has arrived, and with it, some good and bad news. First things first. Finally, the sata to m.2 adapter came.


So now for the serious part, the money part. I'll start with the bad news.

The cryptocurrency im using to fund this project's value has cut in half and it doesnt seem to be going up much.

Now for the good news:

I found a way I can probably use my CPU in this indeavor to possibly increase my earnings by almost double. But that'll be at least a week from now until I start getting the double earnings.

I'm kinda in a sticky situation, things may take much longer than I had anticipated.

and for the case design, I'm kinda holding off on that, I don't have much time to work on it. I'll do it eventually, trust me on that.

I know it's been a while but this project is not dead. I finally made a "breakthrough" and found the pinouts of the connector. The yellow ones and the green one seem to be 12V, the gray and purple ones are 5V, and the rest of them (black, blue, brown) seem to have 0V, so they are ground. However, I don't have a cpu or ram to test, and as I'm aware there are certain signals needed in order to possibly activate some of the "0V" lines.

As for the money aspect: I have been saving up, Bitcoin price has gone up, and hopefully soon I'll have ~$80 minimum of crypto currency to work with. hopefully enough to effectively end the base part of building this thing, without a dGPU. Another great thing is that although I might have mentioned it, CPU prices for this motherboard have gone down a crap ton, sometimes up to 30% from when I started this project

Ram: 16.99
CPU: 39.99
Storage: $25 (though I am a bit skeptical buying used ssds)

=$82.99, though there might be some other fees and stuff that need to be taken into account. Hoping XRB gets to $1, then I'll have $100 to work with.

Another slightly unrelated piece of good news is that I actually have a credit card now, and I will be able to start another project soon, one that hopefully won't take months to gather the funds to get.

update:
I was able to get this from a broken laptop. For free. These things are pretty expensive, and I might be able to get another for 8GB total. This will significantly reduce the time and money to make this into a working system.
Dumpster diving for PC parts is a pretty good idea if you can find somewhere with proper e-waste dumpsters. A lot of very useful stuff to be harvested.

Tbh I don't know if there are that many near my area. Also I would just go there and take stuff and leave if I were to find one?

Pretty much, though it depends on the site and local laws. Some places don't care at all and you can just go and grab stuff, while some places have locks on their dumpsters and/or cameras watching them. Doing some recon first is a good idea. I've heard of plenty of people just asking for permission and getting it, but of course YMMV. I used to periodically plunder the electronics dumpster at a shopping centre where I used to work, which was in a recycling room needing a key card and with camera surveillance, so I guess I had privileged access there. Security never bothered me about it, though I didn't make it very conspicuous either. Got a few beat up but working laptops out of it that I spruced up, installed Ubuntu on and gave to a local organization helping newly arrived refugees. Also various bits and pieces like laptop RAM and HDDs, plus an LCD that I've (in a very ghetto way) made into a portable monitor. While I haven't tried it myself, I used to work with a guy who said the local university was a prime source of free used computer hardware due to their sheer size and regular upgrade rotation (IIRC he got a lot of stuff directly from their IT department, though he did also literally go search their dumpsters st night).

Bigger update: at the best of times, the crypto trade i had set went through. I now have 115 nano(XRB), and literally right at this moment it is at its highest price this month. i had been debating whether to wait or not, but whatever.

115*1.18= ~$135

Bought:
CPU(i5-4570s, came with unknown thermal paste) $37.99
SSD(256GB m.2 sata Dell LiteOn) $29.98
Sata 3 to m.2 adapter(I lost the other one) $2.98
cheap AC wifi adapter $5.29(I may have been able to get this cheaper, too late)
Mini PCIe to x16 adapter $5.79
SATA powered fan hub $2
250W Flex ATX PSU $20 (a bit sketched out about this, but if it fails, I can file an eBay complaint and also I wouldn't feel too bad, as I didn't really spend any of my actual money on this build)

I still have about $27 left. I probably will use it to save for a graphics card in the future, although I might try and get a cheap monitor. I do have a monitor already though that was cheap.

I used all the rest of the gift card on some cheap 60mm Chinese fans, that are 3 pin so I don't have to peg then 100% all the time. I also got a potentiometer type thingy to control it because id rather not have it running 100% all the time.

Also on the gpu side of things, I'm going to at least temporarily use a 1060 from another computer I have. It might fit, just barely. But it will be a bit bottlenecked by the pcie x1 2.0 and I think it would be better for me to use a lower power one so I don't have to cripple the 1060, and I can have better gpu thermals.

Some parts arrived today, a flex-atx psu and a cpu.


its an i5-4570S, the psu is 250W. I put the CPU in there and realized that zipties wouldn't work. So i had to think of a way on how to fit the cpu cooler. I took the half broken intel mounting mechanisms and secured the cooler in a diagonal pattern, which worked. I don't know how thermals will be and if it has good contact, but it should be fine.


yeah, its pretty ghetto. It was pretty rough, and im worried i may have broken something, but that shouldnt be too much of an issue as the motherboard was $8.

I tried to get a display out, and...

nope. But that is what I was expecting. I was trying to find the 2 pins i would need to short to get the system running, and i may have shorted it. I saw sparks. Maybe i should get the power button assembly, but it is quite literally 3 times the cost of the motherboard(though to be fair the motherboard was $8). So, thats out of the question for now. and I ran out of ebay credit. heres to more waiting.

The other thing it may be is that I wouldn't be able to use a secondary monitor as the primary display. if you look at the motherboard, there is actually a 30 pin LVDS panel. I have absolutely no idea how lvds works. Will I be able to use an adapter from lvds to hdmi or something? Maybe I have to get the specific model of screen that was used in this. maybe I have to get any normal lvds display. but then we run into the same problem again. they're expensive.


So I'm out of options other than wait for my crypto to accumulate to make the next purchasing decision. i've also started redoing the whole case design while keeping the same dimensions, though i may have to start over yet again because of the daugher board or something.

worst case scenario is just that I buy a semi-broken lenovo m73z off of ebay, and those are really expensive (for my budget).\


also idk why but discord images are sometimes broken.

i might be able to get an m71z or m72z power button for cheaper but theres no guarantee it will work.
