Oh! I forgot all about this... I'm so sorry! Did you ever get your carboys?

Don't fear code. Here's code for a PWM running at 1hz. This is a complete program for a ATtiny85 based PWM. No resistors, no capacitors, nothing. I've made more complex curves, but this is all you really need for a traditional, linear, 0%-100% PWM. #define potPin 1 #define ssrPin...

!! Hahahahahahahahha!

I expect I'll be drawing my own shield in Eagle and having a batch of boards done by iTead. I've had excellent luck & results so far with both. I haven't done the first bit of Android programming yet, I don't even own the tablet. For now, I'm guessing that putting a bluetooth module on my...

Awesome build! I bought my first Arduino about a year ago, I suppose. I think I've done pretty well with it. I've been brewing, with a breadboard & Arduino, a mashtun on a bench and my e-keggle propped up on some ammo cans. I bought a welder last weekend, so the sculpture build is now...

I did finally find a number of good threads regarding choice of tube & angle. One point that I had not contemplated at all: 0.125 steel will be easier for a novice welder (such as myself) to handle without blowing through. Another bit of good news - I found a steel shop here in Jacksonville...

What about the use of 0.065,then? I'm searching, but not finding, threads regarding wall thickness. The cost for 2" square, 0.065 and 0.125 are $219 and $366, respectively. That's with cuts and delivered to the door by Online Metals.

It seems widely accepted that 2" or 1.5" x 0.125 square tubing is excessive for our needs for a single-tier system, despite its common usage. I've seen some builds from bedframes, and other thinner material as well, but they seem to get less attention and discussion than the over engineered...

I should have nearly enough leftover parts to do this. And that will work awesome for sous vide!

How do you feel the 140 dealt w/ 1/8 mild? I'm looking at getting a first welder, very soon. I'm drawn to the 140 to make use of the 115 outlet (and save a couple hundred bucks!), but fear I'll regret it and wish I'd gone w/ the 180.

I have. That's all I keep now. My oldest resurrection to date is a sample that was stored something like 2 years and 4 months before I re-streaked it. The yeast woke right up, as if I had stored them just a week ago. I do keep them in a fridge, just because the unused little shelf on the...

I'm glad I ran it through the strainer on the way into the keg!

Here's another I put together w/ no provision for PID included. It's much simpler, just a 555 based PWM. I put all of the components within a 1.25 circle on the back, w/ the knob & indicator LED's on the front, so anyone could mount it by drilling a 1.25" hole, and 4 small holes.

Let's see if this works.

I guess I'm at the extreme end of the bell curve. Mine won't even consider tasting anything I brew, but supports my habit in every way. She encourages me to brew more frequently, to buy more gear, etc, etc. I can't always let her know that I'm looking at a particular piece of gear because, if...

I have a couple that I'm putting "the last batch" through now. How soon do you need it?

I agree! I read your code awhile back. After MUCH trial-and-error, I realized that the key to the PID library is only using PID once you are at/near the setpoint, and to use something else to get you into that band. Then, a long time after THAT, I realized that you had already been down this...

You would think so, wouldn't you? However, I did some tests setting "coarse" to 6 and 7. In my system, I need to back off at 8. Any more, and I start to overshoot. Which is exactly what I did first. Then I took a day, basically, just trial-and-error all day long with different settings...

And here's how it turned out:
