Custom phase change controller "Golden Froster"

[pythagoras]

Maybe tyrou thought, as I did, that Argentine uses 110v ac supply.

If you use 220v then he has no problem

John.

[Ssilencer]

Yeap, I tought so, anyway, no problem to do a 110v version one.

Funny thing we being talking for other people we are the advanced diplomatics

[Tyrou]

Great, I didn't know that argentina uses 230V

very nice controller there.
if you know what you doing with PIC chips and LCD's you can make a hole lot of things. my last job they designed HF radios they were using some really cool chips, ones where you program the chip to tell it what pin does what, makes routing pcb tracks alot easier, i was only a service tech though, no designing for me, I would like to though.
in a few years i hope to go to university to upgrade me electronics diploma to an engineering degree in instrumentation and control or electrical engineering.

I want 20 please!

[Golden_Eagle]

I want 20 please!

You´ll have to wait a little !! I´m working as hard as I can

[9mmCensor]

It would be awesome if you made a simple temperature monitor like the Crystal Fontz 633.

That would be sick.

[Malachia]

I want 20 please!

one is my birthday present???

kayl: keep studuing! it´s the best you can do, if you want to be somebody, just remember! "... knowldege is power"

well, it can be done, but I think it wil be better to get wichever you find in the market, just to save some money.

Any other case, just send me a PM

Here we go...
This is the Control Card


This is the Power Card

[wambas]

And what about something for a 220V fan? :P

[Ssilencer]

Hey wambas, throw that 220v fan to the toilet (not a good idea)
You get what you pay for (anything is posibble)

thanxs, the pcb layout looks neat and well planned.

[bmod]

Very well planned and designed guys. cant wait to use this in my system to replace my
prommy controller. Looking foward to add more temp probes.

[Epsilon]

I will try to make one of my own
i study electronics (will be going for industrial automation instead of electronics part) so i could make my own .

[total_assault]

very nice, im just wondering what the electronic component is called attached to the heatsink I've seen it before in pc power supplies cant make out what it is.

MOSFET's?

[Golden_Eagle]

actually they are voltage regulators, transistors and other staff

[Unknown_road]

are those triac's on the power board?

[Aphex_Tom_9]

actually they are voltage regulators, transistors and other staff

arent the things which are bolted to the sinks MOSFET's? that was his Q (as i saw it)

[Unknown_road]

voltage regulators look a lot like mosfets and mosfets are transistors

[Golden_Eagle]

Unknown_road you are right,, and yes there are some triac´s for the compresor and the pc-psu, Maybe ill start using relays to remove those big hs´s

[Rabbi_NZ]

Very nice work Golden_Eagle, thorough design and tidy work

I'm in the process of trying to design one for myself too... a few tips (nothing that would give away any specifics) would be greatly appreciated.

1) Do you also supply the power supply for the compressor, or do you just plumb into the existing circuitry to turn it off/on?

2) To maintain a set temperature do you:
* Turn compressor on/off?
* Throttle compressor speed?
* Turn the condensor fan on/off?
* Something else?

3) Did you use Thermistors for temp monitoring or something else?

Thanks in advance for any help you can give me

1) The compressor is feed by the 220v line; the controller switches the energy when it´s needed.
2) The temp goes free, it reaches a balance between the phase changer´s
and the precessor´s one.
3)I use ic´s for the probes
