got the software done. Here is a picture of the front panel. If anyone interested in using this software let me know. I can send you a copy of the executable.

Fine tuned software today it works great. Also ordered the relay bases, so when they get here I will wire them up and install the relays. This thing is getting close to done enough to cook a batch.

Dude the coke coolers are just sick man! awsome, I'm jelous.

check roto mold they ship ups and it was a good price when I baught mine.

Success! I received the DAQ today and installed it in my PC and it works! So far I hooked up the PC to the "electronics cradle" and ran the software to verify it controls the PLC correctly and that is all good. PLC is switching like its supposed too and the thermocouples are reading temps. So...

Good news! Got another DAQ for 100.00 off ebay. It should be here sometime next week. With it installed I should be controlling the PLC and monitoring the temps by end of next week. I also ordered a couple relays and bases so I can start laying out the 18 relays on the electronics cradle and...

Here's a picture of the electronics cradle with the PLC and interface board installed. Now I have to put the 18 relays that the PLC will control on it also and then mount it under the diamond plate of the rig.

got some bad news today as I was testing the setup noticed thermocouples were not registering any temp values. Turns out the DAQ card is not working properly so I have to get another one. Bummer. But on a lighter note, got the PLC mounted to the electronics bracket along with the interface board...

Here is the updated schematic.

Did the ladder logic and it works as planned so I have 16 outputs that I can control by what address I present on the 8 inputs. I also got interface board almost finished. Here is a picture of it. I am now working on updating the schematic to show the new wiring configuration and will post that...

Got the power supplies! I did the test circuit and I was right had to adjust I/O input resistor to 1.5K ohm to reduce input current draw to acceptable level. While doing all this, I decided to use the DAQ as an address input to the PLC. This way I can setup the ladder logic to use a sequence of...

I had marks in mine also found out if you heat it up too much it birnishes and makes the marks. I found that if you keep it moving and don't dwell on a spot too long even if spot isn't finished move on and come back to it in a few minutes to give it a chance to cool and you will keep the spots...

Got all the parts needed for the circuit except the power supplies. China's slow boats are getting faster haha. Setup a bread board with the circuit on it and am going to run some tests on it to make sure my calculations for current draw etc. are correct before I plug it into my DAQ card and...

well what do you know, the slow boat from korea just showed up with my thermocouples! got them mounted now I just got to put circuit together and wire them up when the rest of my components get here.

Well mounted the hot surface igniters and installed a drain pipe in my brew room. I received the parts from mouser that I ordered for the circuit yesterday. I am going to mock up part of the circuit on a bread board and do some testing on it. I can't put it all together until I receive the power...

I received my igniters and I noticed there is no reference to where the ideal place is to place them by burner. What was the distance you placed yours from the burner and is it supposed to be sticking into the flame or next to the flame of the burner.

I got the thermal igniters today in the mail. Unfortunately the rest of the components needed to build the control circuit are on a slow boat from china (1 is on a slow boat from Korea) and aren't expected here until Jan 20th! That sucks. So in the mean time I am going to make a brew on this...

Oops upladed the older version of schematic. Here is the new version.

Cabel showed up for the DAQ card and I got the schematic done for it. I am going to have to build some circuitry to be able to use the DAQ to its fullest. Here's a schematic.
