Theres no major reason, as you can probably tell this is a pretty big example of a project that has run away. The thought was:
1. Looks cool.
2. Were soldering fittings so the hard plumbing actually makes it cheaper fitting wise (only need to drill triclamp blanks). We have also access to tubing benders and such.
3. Price, while it is more work I can get 1/2" .035" SS tubing for ~$2.30/ft locally when i factored in shipping to the silicon it was actually more.

We were going to make them ourselves. Solder in some 1" Ferrules, drill some 1.5" TC blanks and solder in a 90 deg compression fitting. As I said, with the 50L kegs, I'm not sure the limited measuring range of them makes them worth doing. Still undecided, for now were not going to bother soldering the ferrules in for them.

Thanks, in general the build has been slow progressing so I've had lots of time to plan that out. That said my biggest mistake was putting the main power on the right, and the breakers on the left (hence all of the 6AWG wire jammed at the top), I really should have bought the bus bars you can get for those breakers (and probably just stuck with 2 elements like a sane person).

Thought I'd post two of the smaller items I recently completed.

22mm RGB Pilot Lights:
As I am using the BrewTroller, there is an addon board (RGBIO8) that supports wiring of auto/manual switches and will drive RGB (multicolor) LED's so that 1 LED can display any number of colors to indicate staus (ie. Red=off, green = manual on, blue = auto on, yellow = auto off, or whatever you choose). As you don't seem to be able to buy 22mm RGB pilot lights I decided to make some.

Picked up some standard 22mm White Pilot Lights off ebay and ripped out the guts. Sanded the end with some emery cloth to better diffuse the light (works pretty well). I then soldered them to some pin headers to provide a connector, glued the pin header and LED into the gutted pilot light. It was pretty tedious but they turned out pretty well.

DIY DS18B20 Temp Probes:

Picked up some 1/4" .020" SS tubing to use to make some temp probes and tubing for the volume sensors. Cut them and had the ends TIG welded shut. I bored out some TC end caps and silver soldered the tubing into it. The brewtroller guys recommend (along with the OEM) that for longer runs/noisy environments you add a RC filter at the probe. I then soldered a resistor and surface mount capacitor at the end of the probe (most painful part by far, not the best soldering in the pic but by this time I had lost most of my patience). I then soldered the probe to some 3 conductor wire added some heat-sink compound in the probe end and inserted the assembly. I crimped the tubing down on the cable, and used some adhesive heat shrink to seal it all up. Pretty happy with how they turned out as well.

Default Temp Probes

You made your own temp probes?.......Hhhhmmmmm now that has me thinking....did you flare the end before you welded/soldered it to the TC end cap?
I know your going the Adrno route.....Will these also work with PID's?

Going to be dropping you a PM.

No, I didn't flare it. I had a 1/4" hole drilled out in the center of the end cap, also had a small fillet put on the wet side of the end cap (to make soldering a bit easier), and soldered on this side. It appears to be plenty secure, I haven't used them to brew yet but I have leak tested them by connecting to a garden hose (which should be more pressure then they will ever see)

These particular sensors wouldn't work as I'm using the DS18B20 sensor chip, you could do the same thing and insert a PT100 RTD element though which you could then use with a PID. RTD sensors are much more available though, so you may be better off buying vs making.

IE: http://www.ebay.com/itm/RTD-PT100-Te...item3a79cc4bf2

I still have some more cleaning/polishing to do in the attached pic, but you get the idea.

Here's a pic of my control panel model so far (still a work in progress).

The white lights are RGB LED's that will be tied to the 3pos switches below them (red= off, green of on, blue = auto on, etc). The two switches on the bottom far sides are likely going to be control for the exhaust fan and the one on the left may be a water supply motorized ball valve (for auto-filling) still undecided on that one tho

The yellow led's are 240V fed directly off the output to the elements, as a final indication as to what elements are being fired.

A few more pics of a little bit of progress. Also in process of getting the control panel water jet cut, got everything else for it so I should have that finished soon.

Is that a trub filter on the bottom of the keggle? I wonder if it will clog like that.

Yes, it's the Brewers hardware one.

Perhaps, results seem mixed. Also considering adding a false bottom to BK to provide some extra filtration, time will tell though. When you say "clog like that" where were you thinking it would be placed?
