I'm curious - why use a arduino yun at $70 when you can use a raspberry pi at $35? Is it about the stability of using a micro controller?

Hi Mat, Now that you can flash the EEPROM separately, I'm wondering about the possibility of reading the settings, and writing them back in a simple format. I was thinking of smothering that would write pr0 temps and days in one hit. One type of interface code be a web page that had the...

This one has a single ssr output , who knows what the chipset is! http://www.dx.com/p/xmt612-pid-1-2-pid-temperature-controller-black-205178

Ha - that's funny! I added it so I'd have a reference to the forum, git page and forum, and my wiring - I was going to fill in the back story later. I'll have to do a post for you of my mashing controller- I'm controlling a ssr for mash temperature, with real time pH measurement as well. It can...

One option is to add to the arduino serial commands, 'v'. It could show the code version, and possibly EEPROM content version if you go that way. Another would be a power on version number, however this would require a start up timer of sorts... So may not simple!

Sorry - I was not clear. If it was on the menu, it would be a read only item - the up/down would not have any effect - only exit up a level. Personally I don't like the multi-key sequence things - I always found it tricky on the original unit. The version would need to be stored in programme...

Is there room on the setup menu to add ver menu? Then you could show the firmware build number. This would be useful for determining if a unit needs to be updated after it's been in the field for a while...

I managed to flash a v1.0 with the etherten board. It was a wiring issue, I had the vcc going to the arduino vin, rather than vcc. Dooh. How it managed to power up the stc-1000 from that is a wonder!

The stickers on the outside of the units have slight differences. Perhaps we can determine a v1.0 board From the graphics?

That is surprising as I thought there was only 500ma on a USB port.

The source shows this ID Serial.print("Device ID is: 0x"); Serial.println(deviceid, HEX); if((deviceid & 0x3FE0) == 0x27C0){ Serial.println("STC-1000 detected.");

What power supplies are people using? Is 1amp enough to run the uno and the stc-1000? Thanks

I uploaded to a freetronics ether 10 board. The detect seems to be sporadic, and it won't flash, I get the following STC-1000 NOT detected. Check wiring. Device ID is: 0x27C5 STC-1000 detected. Device ID is: 0x0 STC-1000 NOT detected. Check wiring. Device ID is: 0x0 STC-1000 NOT detected...

I have a rev 1.1 power board unit like Disney7. I can't read the chip markings, however it does have 20 pins. Iscpdat and iscpclk appear to the 7 segment so look accessible. nMclk runs from 4 through a resistor, and then seems to go through the board to behind the display. It looks like it would...

Thanks Mat for sharing this project. I have been controlling my mash with a custom written node.js app on a raspberry pi. I was wondering how much space you had left in the stc-1000+ memory. Would there be enough space to support using the serial out as a Data logger? And perhaps take serial...
