WOW.... Snakes & Ladders ?!?!
What the FUCK.
That is all.
Will this do minesweeper, yes?
How quiet/noisy is it?
Just finished a prototype temperature controller that measures the difference between ambient and coolant temp, and runs the radiator fans to keep the difference down.
Very simple, using two thermistors, an op-amp, and a mosfet.
The circuit has variable resistors that can vary the gap between the ambient and wanted temperature, and gain control that adjust how fast the fans speed up to reduce the difference.
The fan is controlled linearily, so no funky PWM here. Wouldnt be that hard to implement, but for now, its just going to be a linear control. There are 4 fans to control, so if the mosfet gets really hot, i may just watercool it...
Fairly quiet, the fans are only running on 5 volts, and with my temperature controller, will be even quieter, unless im gaming, where they will speed up automatically.
I second that
Well i have moved the temp control over to PWM.
Analog linear control is such a pain in the ass
I have also put some new mesh on the front of the machine, and reached my goal of a stable good overclock.
NEWS NEWS NEWS
PWM temperature control is in beta stage and being tested now.
I am not sure if its sensitive enough yet, it doesnt speed up that much under load.
But some testing will see how it goes.
but the real news is i finally located the side panels!
Not just any perspex, but real tough polycarbonate.
I have two pieces, and its fairly large, so there will be enough left over for the top, and any other bits i want to "hide" behind smoky dark perspex.
here it is testing on the UV watercooling.
Flash is on, so it actually looks a lot better then that.
and with UV off.
I hopefully should be able to cut it and fit it tomorrow!
With flash off, you can barely see a thing apart from the leds on the motherboard, which im going to cover anyway.
With the UV tubes off, its going to be hard to see whats inside.
UV on, and all the cool stuff comes to light.
Unreal! i love the choice of side panels, something different from your usual clear perspex!!
I didnt manage to get the polycarbonate cut today, the place was closed.
Will try tomorrow.
In other news, i have redone the pipes for the ram, hoping to get a bit of of an even cool, before it kept air locking.
I have also put a particulate filter in, using mesh. This is to catch pieces of metal and plastic floating around in my loop due to the whole home made nature of the beast.
This will also be a part of the bleed system that will all conglomerate into a water feature of sorts that will bleed coolant and air from all catch points into one place, and then be pumped back into the system.
This will add more pipes, another small pump and other cool things. Its getting more complicated, which IS a bad thing, but i cant help myself. The more complicated, the more pipes, the more twisted up it will look on the inside.
I have redone my coolant system due to the silicone tubing going opaque, and very slightly porous. The pipes were going white, and I could always smell the coolant, even though there was no leaks.
So i have moved nearly everything over to 4mm vinyl tubing that doesnt get affected by the coolant, and is totally transparent.'
My polycarbonate is cut, and i will attatching them this weekend hopefully.
Pics of the new tubes!
They are thinner, and a bit tough, but it gives the machine a lot more organic look, which suits my theme of "jain technology"
The UV cathodes will be going as soon as i find a good cheap source of UV leds.
WE HAVE SIDE COVERS!!!!
Polycarbonate is fantastic stuff. There were at least 3 seperate occasions, including actually dropping the stuff on its edge that would have completely destroyed a perspex sheet.
Polycarbonate just bounces.
Very nice indeed.
Hats off... you've really gone all out!
Looks brilliant. Really impressive watercooling. It's gotta be one of the best mods I've seen in ages.
I really like it how the polycarbonate is secured to the frame of the case, so rather than being a window it's a see-through side panel. The colour of it suits the style of the case well, especially with the UV lights on.
take the top off the optical drive and spin it 90o so you can see the disk spinning
The drive is only there temporarily. Its coming out into the super mod thats still a secret.
Actually I think I just read its work log...
