Stc-1000+

Amazon only has unflashed from what I can tell, and inkbirds are all single program and no ramping from the descriptions.

Depending on where you live I can flash an STC1000+ and ship it to you. Shipping might be a killer.

Minneapolis. I may just buy the arduino or a friend may have one to use and diy it!

I still use a STC1000+ but there are better options out there now. Look at Fermentrack and the BrewPiLess threads on this board

Here is a doc that Lee put together sorting out all of the controllers

Thanks for the info!!

Not sure if this unit can be flashed to run STC1000+ but for six bucks it's worth a shot.

Can anybody tell if this unit can be flashed? https://www.homebrewtalk.com/forum/threads/cheapest-i-found-stc-1000.672358/#post-8723065

US $56.00 That's an insane price and if he sells one I hope he kicks back $50 to alphaomega
Edit: Wow, the guy has sold 4 units at 54 bucks each.

Looking for a link to print a 3D enclosure for the STC1000

One of my STC1000+'s bit it and I can't figure out how to fix it. Can anyone vouch for the flashability of the
this link? It has worked for me before, but it's been about 3 years and I want to confirm if possible. Thanks!

It says its an

temperature controller STC-1000 A-400P version

in the description - I would email the vendor and make sure

 

[Bigdaddyale]

What's wrong with the old one? I think people have repaired them by replacing the relays

 

[Bigdaddyale]

 

[stoneBriar]

I'm not sure. The display no longer lights up, but the pins leading to the PIC have 5v across them. I'm not sure where I can check to see what's wrong.

I got nothing other than checking all the caps for bulging tops or leaking schmoo

 

[stoneBriar]

So nothing seems obviously wrong. I have an Arduino Nano with the correct picprog loaded to it, I plugged that into my STC, the Nano blinked green then the STC made the slight buzzy “I'm flashing” noise when I plugged in my Arduino. The green light on the nano board blinked fast for 2 min, then quit (standard as I recall) but when I unplugged the nano and put the STC on mains power, the LED still didn't turn on. I don’t know enough about Arduino to get them all hooked up together and “ping” the STC. Heck at this point I can't even get the Arduino Software to recognize the nano...

I can take a look to your STC and Arduino if you manage to pass it some how to Seattle area.

Much obliged Brumateur. Got a bit more info! I managed to power the PIC directly via an external 5v power supply and it lit up just fine. I bet the power supply is dead. I confirmed it's receiving 120v in, but as best I can tell (chemist, not electrician) it's only putting out 5v instead of 10. Anyone got a line on a replacement for that little orange box? Or a diagram of what to poke with a voltmeter to confirm my hypothesis?

The "Orange box" is a transformer and , most likely, it's OK. Semiconductors failing much ahead usually. Could you make a picture of area near transformer?

The yellow arrows when grounded at the yellow circle are 5v DC. I'm pretty sure those are the other side of the transformer. The AC side of the transformer reads line voltage. ignore the red and blue wires, they run to nothing right now (was for an old project).

As a work around you can take 5V wall charger and solder it to 5v and GND
Use at least 2Amp 5V charger

Between the arrow you must have AC voltage 6 o 7 volts at least.
there is a 4 legged round rectifier bridge next, that will produce 12V DC, since the relays are 12v.
Right where the red wire is soldered there is a transistor shaped voltage regulator, 78L05 I guest.
That one is the main suspect to be blow off.

 

[stoneBriar]

Great info, thank you Lalo_uy! I ordered 2 replacements and they are on their way. I'll post here confirming if they are the flashable 110v versions.

 

[stoneBriar]

Confirmed. I order 2 of THESE and changed the "color" to 110v. Both flashed easily and the board is stamped with A-400P v 1.1

V1.05 of Matt's software.
Been using it in SP mode just for a kegerator. Went to go tap my new brews today and it was not cold. Unit was on but not the fridge, then I saw a indicator light that I don't remember. It's the decimal point for F or C. Can't find anything on it in the manual. Is this light a indicator of my problem? Thanks!

 

[Bigdaddyale]

How many sensors are you running?I think that's the indicator for the second sensor

 

[Nrose07]

Just one.
