stc 1000+

[nosco]

Just wondering if anyone on here has tried one of these units. I had a quick search but could'nt find anything. Surprising if thats true coz even with my lack of electronics and programming knowledge it sounds pretty easy. Im just waiting on some Dupont jumper cables?. With a UNO, 5x5 pin headers and some jumper cables it cost about $17. I have an Elitech STC which isnt compatible but the first STC I bought for my ferm fridge is. So I'll use the Elitech as a back up.

So has any one used them before as a ferm controller? I have already loaded up the UNO with the biz. Just waiting on an ale and then ill give it a go on a pils that i have waiting.

Yeah mate, the hardest part is holding the pins onto the stc. If it fails just run it again. Surprised a search didn't turn up with anything.

Pm me if you have any dramas.

This is one of the good threads on this subject.

I've just flashed one for Mardoo, when I checked for the latest version I note there are a few new versions of the firmware.

One interesting one is the single vessel brew control firmware. It can control a pump and 2 elements!

Okay, this has 'win' written all over it. Moad and Mardoo, we will be talking... :beer:

There is also a supplier on aliexpress that has the right hardware for around $25 delivered. It has to be v1 A400_p

is that already modded to 0.1'c accuracy? (not that I think 0.3 is bad.. but you know.. it aint 0.1'c )

Any time mate, the RIS is delicious thanks very much.

Not sure what the accuracy of the STC is but you can set the hysteresis to .1 if that helps? I'll be controlling my ferment with a BCS soon enough!


Edit: I know what you meant now, yeah within .1 either side so a range of .3 is the best you will get with the STC. I don't think it is a problem though as you will get that variation within your fermenting beer anyway wouldn't you?

I did see that one. Pretty dam cool but I'm wondering if it would be easier to wire up a really cheap PID. I'll stick with a ferm controller for now.

 

[Moad]

my thoughts too nosco, PID is $70 vs stc of $25 and some effort although both look equally as confusing to program at first

edit: on second thought auberins ramp/soak model is about $90 delivered so it does come out a bit cheaper!

I was thinking more along these lines. Id be happy with manual control and a pump at this price if it could run my 5500w element. Im still a relative noob so baby steps. Its a rex c-100 which Tex n Oz mentioned in another post of mine but Im not sure if he was taking the piss or not. Still PIDs look pretty easy to wire up but Id still have to get my mate to help out.

 

[Crusty]

Do you plan on selling any flashed versions moad?
They look the goods that's for sure.

the custom firmware allows you to program step mashes etc without fiddling, maybe not as accurate as PID's but not sure.

Happy to do it for cost, they don't take long to flash. PM me if interested

I've got 4 STC 1000's & saw somewhere how to tell if their flashable.
I can't be arsed trying to find it.

Open it up like so. Look at the printing on the board.

 

[Crusty]

Well bugger me, all mine are flashable.
I downloaded that programming zip from GitHub but it doesnt contain the picprog file that I need.
I'd like to get the board to flash mine + some mates here even though Moad has made a very kind offer to do it for me.

It's quicker to use the web based profile editor to download the file.

Select stc 1000+ vanilla single probe.

Put in a couple fermentation profiles, eg.
Ale, lager, nottingham faux lager.

Then download that.
