WHO would like for a "starter" cirquit for Prometeia Mach1???

[hipro5]

As we all know,Prometeia Mach1 is NOT capable of starting our computer properly.......As a matter of fact it doesn't even work.....ONLY a few mobos can suport that(ex. EPOX 4PCA3+)

Now who wants a designed circuit giving it free for the public to solve this problem once and for all???...You will NOT have to put a second PSU(some of you have done) so as to feed the Prometeia first.......It is very simple and you can do it by your self (if you know some things about electronics and soldering things) OR you can give the circuit to a repairing TV technician of your neighbour so as to do it for you...

It is working with ALL mobos out there...... ;) :D

Let's see........

[Jack]

sounds awesome!

Hipro is there anything you can't do? :slobber:

you can truely do amazing things hipro! :)

i'm still waiting for the DDR maximizer,
so i don't have get out of my chair and mod my mobo ;)

Yea.......A lot of things....... :D

[morbidj]

That would Rock Hipro, man keep up the good work.

[bias_hjorth]

YES YES.. would be awesome! Could it be designed so it´ll startup with a variable delay that you could choose uself..

[hipro5]

Yes it could......... :D

[hipro5]

OK.........10 votes is OK for me so far.............I design it in no time (bam-bam as we say here in Hellas)....... :D

Take it....... :D

http://www.thelab.gr/images/Hipro5/Temp/Prometeia's%20Starter_png.png

COMPONENTS :

IC1 = LM555

RESISTORS :

R1 = 100 KOhms
R2 = 25 turns trimmer of 1 MOhm
R3 = 15 KOhms
R4 = 2.7 KOhms
R5 = 560 Ohms

CAPACITORS :

C1,4,5,6 = 100 nF/25Volts(or above)
C7 = 2.2 uF/25Volts
C2,8 = 100 uF/25Volts
C3 = 1000 uF/25Volts


D1,2,3 = 1N4002(1Amp diodes)


RELE's = 12VDC(coil) - that can handle 1Amp(for "secure" rele's reasons)....

T1 = BC546C (or equiv.)

JP1,2,3 = Dual Pinheads male......


Before we put it into out rig (computer) we check it if it works properly and for trimming reasons...

Before we start we HAVE to "Short-circuit" the "JP3" so as the timmer (LM555 - IC1) start working - this is done by "closing" the T1 (BC546) transistor circuit to the rele "K2" and feeds the IC1 with voltage...

The LM 555 works as a timer...We trim the R2 so as to get 1.5 sec time on RELE "K1"...We will hear a "tic - tic" low noise coming from that rele...REMEMBER that to start working the IC1, we HAVE to short circuit the JP3...

Now imagine that we have it on our Prometeia Mach1...Prometeia's "reset" is already short circuited by default...When Prommy reaches the proper temperature (subzero), it "releases" it's reset pins' to an "open circuit"...When this happens, T1 will be "on" and CUT the IC1's Voltage so as NOT to "give" any other resets on the motherboard...You can now reset your mobo as usual.... ;)

Feel free to ask anything ........

P.S. Sorry about my English technical spelling..... :D

Yes.........Thank you.......

[bias_hjorth]

wow that went fast.. If I only had the skills and part to built it :D

[echow87]

totally confused just by looking at the pic...

mind producing these and sell em?

edit: looks like the board inside the mach...how about modding the boards for a fee :)?

Not intented to prodused and sell them......Too much work to do already......Take the cirquit and go to someone who knows about that so as to make it for you...... ;)

[Hell-Fire]

Very nice circuit work hipro. :up:

[enzoR]

how about a sticky?

[bias_hjorth]

I vote for sticky..
We circuit noobs gotta have time to do this :D

[Hell-Fire]

Consider it stuck gents. :up:

[hipro5]

Sticky for now........Well...Thanks a lot..... :D :toast:

Now.......HOW about design for you AND the PCB so as I can do your life easier???....... :D :toast:

[tennvols_69]

can you design a circuit for us custom direct die guys thats like the prommys as i hate having to wait by my comp for it to cool then turn on. and it would be nice to have auto shutdown if temp goes to high.please hipro5 it would be much appericeated by me and many im sure.

You could find a lot of those with double relays built in as was the Prommie Mach1.......... ;)

[G H Z]

Very cool hipro,

Has anyone make this yet? Just wanted some results before I attempt one;) It is annoying to go thu all the steps now when powering up/down.

DON'T worry .......It works like a charm.....I've builted 5 off them already.......It has been tested a LOOOOONNNGGGG time ago...... :D

I'm just now publishing it...... ;) :)

[Think]

Wow..great job. I wonder who I can call to build it for me in Toronto?

[JNav89GT]

I'm obtuse, can you explain a few areas to me please :(

[craig588]

K1 and 2 are relays

[blowsion]

c'mon hipro make some and sell them ,i need one for a second hand mach1 i have here
you can do it am sure ;)

[hipro5]

Sorry M8.........No extra time to do so...... :(

[sai]

Could anyone make me one of these ? What will the parts cost ?

[black rose]

I might end up with a free couple of weekends. I'd be willing to slap a few together.

[Think]

I might end up with a free couple of weekends. I'd be willing to slap a few together.

I'd be interested in one as well!!

Let me know :banana:

[black rose]

I'd need an idea of how they are encased and dimensions, since I don't have access to one of my own :(

[hipro5]

Because I don't have much time here , IF someone who's capable of geting a film of the circuit , make it PCB and solder the parts on it , whould surelly help others who can't do that........IF someone wants to send him a film of the PCB so as to help the others out there , please PM me so as to help him out......Thanks..... :)

[rhino56]

another nice advance in technology hipro. i wonder why they made the mach one with such a problem circuit anyways.

[SPL15]

Hey Pretty Good Hipro!!

Got some questions/Comments though. So this circuit basicly pulses the reset of the motherboard constantly until the Mach I microcontroller reaches the set temp which stops the reset pulses and resumes normal operation? So basicly instead of the constant reset short the Mach I microcontroller gives, this circuit makes the reset short pulse every 1.5 seconds.

It think this is a very good solution if you dont want to use an outboard 12 volt supply. I'm happy there's someone else here that knows engineering!! Good work!!!

The way I did it though (Which is MUCH more complicated than your solution) was to use a 75 Watt single output 12 volt switching power supply and use it to power the mach I Microcontroller, fans, waterpump, lights, 12 volt accesories and standby circuit. I use the reset output from the Mach I pretty much the same way you use it.

Basicly What my design does different is that it keeps the computer totally off until the temperature is reached, which lets the unit cool down much much faster. When temperature is reached, I use a one shot pulse (500mS)to fire a relay that shorts out the power button on the case which turns everything on. Also, Since I use 120 VAC fans, I use the Mach I hysteresis settings to control when my computer shuts off since they are not used by the fans and heater anymore. I basicly shut off or turn on my mach unit and the computer portion turns on and off automatically. I use the fan speed setting to determine at what temp my computer shuts off. I use the hysteresis signal to fire another one shot pulse to a relay which shorts out the power button on my case. I have windows set up to shut down when the power button is pressed so When the temp rises to -5 Celsius, my computer shuts down automatically from the Mach microcontroller's hystersis fan speed setting.

I think for most people though, your design is much much better because it is much less complicated to build and implement and you dont have to drastically modify wiring in the mach unit like you do with my design. Again great work!

[hipro5]

Thanks SPL15 ...... :toast:

Yes I had mine with the circuit described in these pages and after that I used an external PSU also for the Prommie too.......BUT most pll with the Mach1s whould like something to be a bit "easier"........and fast enough to be build......They don't want to involve many things together.......That's why I've posted that....... ;)

P.S. I have tottaly forgoten of this thread........Shi(f)t I've promised someone a piece of this thing and I forgot it.......I'm sorry......I'll build it as soon as posible...... :(

[SPL15]

Ya I agree 100%. I'm glad there is someone lookin out for the normal people who don't have the knowledge to design and build a complex circuit to do something that should have been done by the manufacturer. Your circuit definitely accomplishes this goal with little work involved.

I know exactly what you mean about forgetting to build someone something!!! I'm guessing your as busy as I am with your real job. Glad you take the time to help out people though, I know I should more than I do, but just dont have the time/motivation. People like you help the industry more than you'll ever know.

I'm planning on doing a tutorial on making PCB's from UV light sensitive boards. I think it's the easiest/cheapest way for hobbiests to build a PCB. It'll definitely help people make this project even easier for people.

[JOSTech]

lol what funny about this is my friend knows well more about computers than i do but i can read this scamatic and know what it means and if my friend looks at this he has know clue what it means

You are definitely the smarter of the two!!

Computers and electronics are totally seperate identities, just like electricity and electronics. It's insulting when I say I'm an electronics engineer and people reply with "Oh you fix computers?" or "Oh my dad does that, he is an electrician". Most people dont realize people design electronics, they are not magically made by Computers.

Learning computers is easy, learning electronics and understanding it is much harder. It's really funny when I'm explaining the reasons why something wont work in a computer to someone who has a masters in computer science at my main job. If you can understand electronics, computers are a joke to understand.

Full ACK!

Damn, I hate this sentence. I don't know how often I had to hear that! Well I earn some money by administrating some computer networks to live while studying and every time I talk to a customer and tell them what I'm studying I get that answer. Ok, it's obvious but I hate it. Everytime I fix damn windows problems I know why I went to university: I don't want to do that for life-time! I wanna do something interesting and for me it's elecrical engineering.


hipro5: Fine that you've made a prommy control unit. :) I wanted to do that when I started studying but due to the lack of time I dropped that project. And short time after that I sold my prommy. Your solution is as simple as good :). I thought about a completely new controller with LCD.

[froudeg]

Nice job hipro :)

Even tho that 'pulsing reset' system does work on a lot of motherboards - it certainly doesnt work on all of them....i created a similar function a year or so ago to try and get round the boot issue with Abit IC7 mobo's.......

Even though the pulsing reset does stop the board from booting fully - with the IC7 motherboard it doesnt stop the cpu from getting power during the initial startup stage of the prommy as it gets down to temperature....with a heavily overclocked/volted chip and a cold boot i found the temperature would rise faster than the unit could pull down and i'd have to shut it off.

Some other mobo's also go mental with the pulsing reset - i cant remember for sure but i think my abit nf7-s would starting beeping like crazy and refuse to boot if i pulsed the reset....although it may have been a different mobo but i know at least 2 mobo's i had here did it.

The only sure way to have a phase change unit to start a pc, without boot issues or running the risk of the cpu burning out during the startup phase, without the use of an external psu....is to do it like asetek have and have the 12v and 5v lines from the ATX power connectors, intercepted and cut off by relays, along with the PS_ON wire to the mobo.

Note: Just a word of warning - P4 internal thermal shutdown circuitry does not function when the chip is in reset, i had a m8 burn out 2 p4's during boot up with a vapo setup that didnt cut the extra 12v atx header during the startup stage :/

[bmac11]

Hey guys.. first post and new to vapo..

Has anyone made one of these? I am getting a mach 1 (today!! :) ) and want to make one, but I am some what lost on reading the circuit design. I don't understand what some of the symbols represent. I'll have no problem building one, I just need a kick in the right direction. A few questions..

1. Can I just get the parts and and solder them on to something like perf board? Is this how its done?

2. Where can I find the parts to do it?

3. I've searched for guides about circuit design but haven't found anything that explains what the symbols mean or that are useful.. anyone have any good links?

thanks

[bmac11]

ttt

[MeltedDuron]

hey black rose if your still making these i might want one 'coz i get my mach 1 next week.....

[bmac11]

find me some help on how to read that diagram and I'll consider making a few of them

[persivore]

If anyone wants me to put one of these together for them, I should have some time when I finish college in the next 2-3 weeks. I can't put anything together on a PCB because I don't have the equipment to make them, but I can build it on stripboard/veroboard.
If you want one, just drop me a PM, and I'll work out a price. I'm in the UK tho, so postage might cost quite a lot if you want me to post internationally.

[wittekakker]

I was just wondering how to build something familiar to that.
Going to watch u'r design tomorrow, must get some sleep now.

[bmac11]

Will I need that psu to psu cable when I have one of these?

[CaTalyst.X]

ill slap a few of these together for people in the US if there is still a demand. Shoot me a PM for pricing etc.

-CaT

[spastikman]

Hipro, could you design us the PCB ? :D tks !

[bmac11]

I MIGHT have several of these professional made.. hopefully!! How many people are still interested? Not sure on price yet, but probably not too much. I'm going to try to supply adapter cables too so the unit can be hidden inside the prommie.

[wittekakker]

Dunno how exactly, but yesterday I found this thread again. Seems to be dead, but I have still have a question here so sorry for digging it :p:

There seems to be problems here, but this morning I wanted to test this out meself, and everything did just fine. I installed all wires of my Mach 1, pushed the power-on button and the mach 1 started to cool dwon. My pc went on too, but in idle and blank screen. On -3x°C the mach was on good temp and fans started to slow down, but also my pc booted.
I have mach 1 + DFI nf4 Ultra-D.
Is this normal that it works on DFI nf4 or could it be possible I have a newer revision of the mach or something like that?

[Butcher_]

I'm curious as to why hipro used two relays there for power switching. Given the small currents involved I'd have thought a couple of MOSFETs would do the job better - less power, longer life span.
