Some good news from the supplier I've been working with for these controllers; they were able to add a resistor and a 3-position terminal block to the board so that no physical mods will be needed in order to add the 2nd temp sensor. I've ordered 50pcs of these, along with 100 sensors, so will...

If you want to mount the motor under the table, couldn't you just mount the mill under the table too and go to a direct drive and avoid all the pulleys/chains/belts? My direct drive setup is still going strong, no issues. Sent from my iPhone using Home Brew

Yes, this is a flashable unit.

This thing is definitely sweet, but it's overkill for the application. This motor could handle this load 24/7 in a production/factory environment. That's awesome and I've got no problem with it at all other than cost. If money is no object, drop the $200 and you'll have an awesome setup that...

Edit: sold

Interesting. This is the first "unflashable" version I've seen with the power & sensor terminals close together. Looks like that check is no longer legit. Crazy how many versions of this thing we've come across so far! Sent from my iPhone using Home Brew

This is awesome! FYI, I had to make a small tweak in the sketch to get this to work with the fahrenheit version; after uncommenting the #define for AUTOMATIC_UPLOAD_FAHRENHEIT, I also needed to remove the "AUTOMATIC_UPLOAD_CELSIUS ||" from the #ifdef statement a few lines down. I don't think the...

Mats is definitely the STCmaster, but I may be the less glamorous "flashmaster" as I have about 350 under my belt so far! Sent from my iPhone using Home Brew

Plug in USB, then start Arduino software, then open serial monitor and flash. Before you do the next one you need to close the Arduino software and unplug the Arduino. Then make the connection to the next STC, plug the USB back in, open Arduino software, flash, repeat. And no, you cannot flash...

Settle down kids, save it for the playground. Here's the inlet I use: http://www.alliedelec.com/search/productdetail.aspx?SKU=70133364 Sent from my iPhone using Home Brew

Is there a reason you can't just use the blow off tube for the larger batch you're brewing today? Typically, blow off tubes are used for the vigorous primary fermentation and can be replaced with airlocks when things calm down (or you can just leave them hooked up). Sent from my iPhone using...

Check Surplus Center, they usually have pretty good deals on motors and gear reducers, e.g. this one

Yeah, I suppose I should change that. I only have 20 or so units left , though, so not going out of my way to advertise them. Sent from my iPhone using Home Brew

Correct, I still have plenty of the flashed/flashable controllers available. Thanks. Sent from my iPhone using Home Brew

There is no such thing as a "legitimate" STC-1000, unfortunately. There are many versions and, to my knowledge, no way to determine which one was the original and which ones are copies. All we really know is that version 1.0 is the one that works for STC-1000+. Sent from my iPhone using Home Brew

Yes, Alpha is in Sweden, this was developed on a 220 unit.

So I'm putting this firmware to the test today! I've got a RIMS tube mounted on my MLT and I'm cycling water. I've got a BCS setup to measure temp at the inlet & outlet of the MLT (see pics). Constant Output mode works well / reliably. Constant Temp mode does not seem to work consistently, I...

Yes, having dipped my toe into the waters of Chinese electronics manufacturing to secure a source for the correct version of these things, I can tell you that this is exactly what's happening. They all claim to be "the factory" and will tell you that everyone else is copying them! They also...

Closing this thread as it is no longer relevant to the 'For Sale' category. Please continue the discussion on this thread. Thanks, Will

That, and the relays are rated for >10A, but the PCB/system is not. Sent from my iPhone using Home Brew
